Öğe Advanced heart failure and future of mechanical assist devices: a Consensus Report on Cardiology and Cardiovascular Surgery(Baycinar Medical Publ-Baycinar Tibbi Yayincilik, 2016) Yilmaz, Mehmet Birhan; Akar, Ahmet Ruchan; Ekmekci, Ahmet; Nalbantgil, Sanem; Sade, Leyla Elif; Eren, Mehmet; Orhan, R. Gokcen; Ozbaran, Mustafa; Yagdi, Tahir; Kucuker, Seref Alp; Gurbuz, Ali; Tokgozoglu, LaleHeart failure is a progressive disease. A considerable portion of patients reach an advanced or terminal phase later or sooner, despite all of the developments in diagnosis, management, and follow-up and alternatives which can slow the disease process. As well as the palliative care of the patient in the terminal phase, definite recognition of the patient with advanced disease is vital for the consideration of therapeutic options in this patient population. Overall management and care of patients with heart failure obligates a collaboration of multiple disciplines. In addition, patients with advanced heart failure should be managed by a "heart team", as indicated by the guideline recommendations, since it requires a close communication and collaboration among cardiologists, cardiovascular surgeons, and other medical staff who are responsible for taking care of these patients. In Turkey, we have experienced physicians for managing patients with advanced heart failure. However, we are unlikely to be sufficient in the distribution of the centers and equal accessibility for all patients to therapeutic options. Hence, we still have more to do for the referral of eligible patients and patient circulation issues. This consensus report is developed to strengthen the connection between experienced and certified centers and the centers which take care of heart failure patients independent of the disease phase and other healthcare staff to increase awareness and to provide updated information for the current conditions of Turkey.Öğe Analysis of Heart Rate Variability With Electromyography in Heart Transplant Recipients(W B Saunders Co-Elsevier Inc, 2009) On, Arzu; Karapolat, Hale; Zoghi, Mehdi; Nalbantgil, Sanem; Yagdi, Tahir; Ozbaran, MustafaObjective: To investigate vagal parasympathetic functions by electromyographic R-R interval variation analyses in heart transplant recipients. Design: Cross-sectional and longitudinal study. Setting: Department of physical medicine and rehabilitation, university hospital. Participants: Early (n=8; <3mo) and late (n=17; >1y) heart transplant recipients and healthy volunteers (n=20) were included. Interventions: Not applicable. Main Outcome Measures: The R-R interval variations at rest and in response to deep breathing, Valsalva, and tilt/standup maneuvers were analyzed in all patient and control groups. Further, 8 early heart transplant recipients were followed up at the sixth and twelfth months after transplantation. Results: Compared with controls, both early and late transplant recipients had significantly lower R-R interval variation ratios (P<.05). There were no statistically significant differences between the early and late groups (P>.05). R-R interval variation ratios showed no significant changes from baseline (P>.025) in the early heart transplant recipients. Conclusions: The findings of the study suggest that parasympathetic activities are suppressed in the early stage after heart transplantation and do not significantly recover with time. The electromyographic analysis of R-R interval variation is a simple test that may offer an attractive alternative for routine evaluation of autonomic dysfunction in heart transplant recipients.Öğe Analysis of Heart Rate Variability With Electromyography in Heart Transplant Recipients(W B Saunders Co-Elsevier Inc, 2009) On, Arzu; Karapolat, Hale; Zoghi, Mehdi; Nalbantgil, Sanem; Yagdi, Tahir; Ozbaran, MustafaObjective: To investigate vagal parasympathetic functions by electromyographic R-R interval variation analyses in heart transplant recipients.

Total artificial heart implantation made for the purpose of extending the life span and bridging to transplantation in patients with end-stage heart failure is a good option. We present our initial experiences in the anesthetic management of total artificial heart implantation cases performed in our institution. Five out of seven patients (46.8 +/- 8.4 years) were taken to surgery with inotropic support. Four patients were diagnosed as dilated cardiomyopathy. Three patients were subject to cardiac arrest during the preoperative period and mechanical ventilation was applied for one of these patients. Intraoperative ketamine, midazolam, fentanyl, rocuronium were used in doses of 192 +/- 89 mg, 8 +/- 3.5 mg, 335 +/- 157 mu g and 192 +/- 43 mg, respectively. Fresh donor blood, fresh frozen plasma, thrombocyte and erythrocyte suspension requirements were 2.1 +/- 1.6 unit, 2 +/- 1.8 unit, 0.43 +/- 0.5 unit and 0.6 +/- 0.9 unit, respectively. At least one complication developed in all of the patients; four patients who had sepsis and renal failure died and; 3 patients who were not subject to this complication were discharged from the hospital. Total artificial heart implantation made for the purpose of bridging to transplantation for end-stage heart failure patients is a valuable option and its anaesthetic management is challenging. It is important that anesthesiologists have knowledge about the implanted device and the surgical procedure.Öğe Assessment of right ventricular systolic function in heart transplant patients: Correlation between echocardiography and cardiac magnetic resonance imaging. Investigation of the accuracy and reliability of echocardiography(Wiley, 2017) Simsek, Evrim; Nalbantgil, Sanem; Ceylan, Naim; Zoghi, Mehdi; Kemal, Hatice Soner; Engin, Cagatay; Yagdi, Tahir; Ozbaran, MustafaBackground: Right ventricular (RV) function has great impact on the survival of heart transplantation recipients; therefore, careful evaluation is of high clinical importance. However, there is no standard conventional echocardiographic parameter to assess RV systolic function. Herein, we evaluated the correlation between echocardiographic parameters of RV systolic function and ejection fraction assessed by cardiac magnetic resonance imaging (MRI RVEF) in heart transplantation recipients. Method and Results: Forty-three patients with at least 6-month heart transplantation history were included in this study. Each patient had conventional echocardiography and cardiac MRI evaluation, followed by endomyocardial biopsy and right heart catheterization, which were performed in six hours. Echocardiographic parameters of RV systolic function, RV fractional area change (RV FAC), tricuspid annular plane systolic excursion (TAPSE), RV myocardial performance index, and RV global longitudinal strain, were compared with MRI RVEF (P values were < 0.001, < 0.3, < 0.9, and < 0.4, respectively). RV FAC was the only parameter to strongly correlate with MRI RVEF (r=0.747, P < 0.001); and RV FAC 48.5% value had 90.5% sensitivity and 90.5% specificity to predict the pathologic reference value of MRI RVEF <= 50% (AUC: 0.96; 95% CI, 0.908-1.013). Conclusion: To our knowledge, this is the first prospective study to evaluate the correlation between the echocardiographic parameters for RV systolic function and MRI RVEF in heart transplantation recipients. RV FAC is the only parameter to correlate well with MRI RVEF, and its routine use in the follow-up of heart transplantation recipients should be considered.Öğe Association between caregivers' coping and children's psychiatric symptoms in the heart transplantation process: A pilot study(Wiley, 2021) Kafali, Helin Yilmaz; Kalyoncu, Tugba; Ozbaran, Burcu; Kalyoncu, Emir; Tuncer, Osman Nuri; Ozturk, Pelin; Ozbaran, MustafaOur aim was to investigate whether there is an association between caregivers' coping and children's psychiatric symptoms and quality of life in adolescent heart transplant (HTx) recipients and HTx candidates with left ventricular assist device (LVAD). Fourteen patients were recruited for this pilot study (HTx (n = 8), LVAD (n = 6)). Schedule for Affective Disorders and Schizophrenia for School Aged Children, Present and Lifetime Version (K-SADS) was administered to detect the psychiatric diagnosis of patients. Children's Depression Inventory (CDI), State-Trait Anxiety Inventory, and Pediatric Quality of Life Inventory (PedsQL) were completed by adolescents; Brief Coping Styles Inventory by their caregivers. Six of the participants had an internalizing disorder. Optimistic coping strategy score was significantly higher in the caregivers of adolescents without an internalizing disorder than caregivers of those with an internalizing disorder (U = 2.500, P = .005). Utilizing Spearman's correlation, caregivers' optimistic approach (rho = -0.736, P = .004), and self-confident approach (rho = -0.634, P = .020) had significant negative correlations with children's CDI scores. Moreover, caregivers' optimistic approach score had a significant positive correlation with children's PedsQL score (rho = 0.563, P = .045). According to our preliminary results, it seems that caregivers' optimistic and self-confident coping strategies may be associated with fewer internalizing symptoms and a better quality of life in adolescents in the HTx process. A future multicentered longitudinal study will be planned to assess the effect of caregivers' coping strategies on the psychological adjustment of these children.Öğe Association Between Erythrocytosis and Six-Minute Walk Test Distance in Eisenmenger Syndrome Patients(Wiley-Blackwell, 2012) Gungor, Hasan; Ayik, Mehmet Fatih; Karapolat, Hale; Zoghi, Mehdi; Engin, Cagatay; Yagdi, Tahir; Atay, Yuksel; Ozbaran, Mustafa; Nalbantgil, SanemÖğe Association between the low percentage of forced vital capacity and increased mortality after left ventricular assist device implantation(Baycinar Medical Publ-Baycinar Tibbi Yayincilik, 2020) Ekren, Pervin Korkmaz; Ozturk, Pelin; Ertugay, Serkan; Ozdil, Ali; Nalbantgil, Sanem; Engin, Cagatay; Ozbaran, MustafaBackground: This study aims to investigate the effect of low percentage of forced vital capacity measured in the preoperative period on the 28-day mortality in patients undergoing left ventricular assist device implantation. Methods: A total of 131 patients (111 males, 20 females; median age 54 years; range, 47 to 59 years) who underwent left ventricular assist device implantation with HeartWare (TM) between December 2010 and January 2016 were retrospectively analyzed. the patients were divided into two groups according to the results of pulmonary function test as a forced vital capacity percentage of >= 60% (n=113) and <60% (n=18). Both groups were compared in terms of laboratory and clinical characteristics, and postoperative complications. Risk factors for postoperative 28-day mortality were analyzed. Results: Pre- and intraoperative characteristics were similar in both groups, except for left ventricular end-diastolic diameter. the ventilator-free days up to 28 days was shorter (p= 0.046) and the length of intensive care unit stay was longer (p=0.011) in the low percentage of forced vital capacity group. the 28-day mortality rate was also higher (22.2% vs. 9.7%, respectively; p=0.12) in this group. the history of prior cardiac operation (odds ratio: 4.40; 95% confidence interval 1.19-16.20, p=0.026) and tricuspid valve repair at the time of device implantation (odds ratio: 5.30; 95% confidence interval 1.33-21.00, p= 0.018) were found to be independent risk factors for mortality. Multivariate analysis showed that a forced vital capacity of <60% was not associated with mortality (odds ratio: 3.96; 95% confidence interval 0.95-16.43, p=0.058). Conclusion: the length of intensive care unit stay and duration of mechanical ventilation may be longer in patients with a low percentage of forced vital capacity. Although the association between 28- day mortality and low percentage of forced vital capacity is not significant, the risk of 28-day mortality is higher in this group. Therefore, the patients should be assessed carefully before the left ventricular assist device operation.Öğe Cerebral strokes in children on intracorporeal ventricular assist devices: analysis of the EUROMACS Registry(Oxford Univ Press Inc, 2018) Schweiger, Martin; Miera, Oliver; de By, Theo M. M. H.; Hubler, Michael; Berger, Felix; Ozbaran, Mustafa; Loforte, Antonio; Seifert, Burkhardt; Gargiulo, Gaetano; Gummert, Jan; Mohacsi, PaulLittle is known about cerebral strokes in paediatric patients supported by intracorporeal continuous-flow ventricular assist devices. We retrospectively investigated patients younger than 19 years of age who were treated with an intracorporeal continuous-flow ventricular assist device in the European Registry for Patients with Mechanical Circulatory Support (EUROMACS) database. The patients were stratified by body surface area in Group 1 [< 1.2 m(2) (n = 13)] and Group 2 [<1.2 m(2) (n = 38)]. Cerebral strokes, both ischaemic and haemorrhagic, were studied. Of the 2941 patients with ventricular assist device (VAD) implants listed in the database, 124 (4%) patients were less than 19 years of age. Fifty-one of them (2%) were supported with a continuous-flow ventricular assist device. Group 1 (6 female and 7 male) had a mean age (+/- SD) of 9 +/- 2.3 years compared with 15.6 +/- 1.8 years in Group 2 (21 female and 17 male). Three (23%) patients died in Group 1 on VAD support, whereas 5 (13%) patients died in Group 2 (P = 0.21; log-rank test). Seven (54%) patients with a VAD in Group 1 and 17 (45%) patients in Group 2 underwent transplantation (P = 0.29); of these, 1 (8%) patient recovered (Group 1) with subsequent device explantation. The other patients, 2 in Group 1 and 16 in Group 2, were still on device support at the time of the analysis. There were no cerebral strokes in Group 1, but 4 cerebral strokes (11% of Group 2, 8% of a total of 51 patients in Groups 1 and 2 combined) occurred in Group 2 (3 patients died; P = 0.26; log-rank test). Taken together, the incidence of cerebral strokes in this paediatric cohort of patients with an intracorporeal VAD was 0.1 per patient-year. The incidence of cerebral strokes in children with intracorporeal VADs (0.1 per patient-year) seems to be low irrespective of the body surface area.Öğe Cerebrovascular accidents in paediatric patients supported by the Berlin Heart EXCOR(Oxford Univ Press Inc, 2022) Rohde, Sofie; Sandica, Eugen; Veen, Kevin; Miera, Oliver; Amodeo, Antonio; Napoleone, Carlo Pace; Ozbaran, MustafaOBJECTIVES: Ventricular assist device support as a bridge to transplant or recovery is a well-established therapy in children on the cardiac transplant waiting list. The goal of this study was to investigate the incidence of and the associated factors for cerebrovascular accidents in paediatric patients supported by a Berlin Heart EXCOR. METHODS: All patients <19 years of age supported by a Berlin Heart EXCOR between January 2011 and January 2021 from the European Registry for Patients with Mechanical Circulatory Support were included. RESULTS: In total, 230 patients were included. A total of 140 (60.9%) patients had a diagnosis of dilated cardiomyopathy. 46 patients (20.0%) sustained 55 cerebrovascular accidents, with 70.9% of the episodes within 90 days after the ventricular assist device was implanted. The event rate of cerebrovascular accidents was highest in the first era (0.75). Pump thrombosis and secondary need for a right ventricular assist device were found to be associated with a cerebrovascular accident (hazard ratio 1.998, P = 0.040; hazard ratio 11.300, P = 0.037). At the 1-year follow-up, 44.4% of the patients had received a transplant, 13.1% were weaned after recovery and 24.5% had died. Event rates for mortality showed a significantly decreasing trend. CONCLUSIONS: Paediatric ventricular assist device support is associated with important adverse events, especially in the early phase after the device is implanted. Pump thrombosis and the need for a secondary right ventricular assist device are associated with cerebrovascular accidents. Furthermore, an encouragingly high rate of recovery in this patient population was shown, and death rates declined. More complete input of data into the registry, especially concerning anticoagulation protocols, would improve the data.Öğe Changes in the obstructive sleep apnea symptoms in heart transplantation patients(Wiley-Blackwell, 2012) Ayik, Sibel; Gungor, Hasan; Ayik, Mehmet Fatih; Karakula, Sultan; Akhan, Galip; Engin, Cagatay; Yagdi, Tahir; Nalbantgil, Sanem; Zoghi, Mehdi; Ozbaran, MustafaÖğe Clinical and hemodynamic features of Eisenmenger syndrome patients at the time of first admission: a tertiary referral-center experience(Aves Yayincilik, 2012) Gungor, Hasan; Ertugay, Serkan; Ayik, Mehmet Fatih; Demir, Emre; Engin, Cagatay; Yagdi, Tahir; Ozbaran, Mustafa; Atay, Yuksel; Nalbantgil, SanemObjective: In this study, patients admitted with the diagnosis of Eisenmenger syndrome (ES) in a tertiary referral center were analyzed. Methods: The data of 20 consecutive patients (mean age: 27.6+1.8 years, 7 male and mean follow-up time: 35.6 +/- 9.1 months) with ES were retrospectively analyzed. Demographic characteristics, symptoms, physical examination, laboratory and hemodynamic parameters were analyzed at the time of first admission. Results: The most frequent underlying heart diseases were ventricular septal defect (VSD) with complex congenital disease (n:8, 40%) and isolated VSD (n:7, 35%). 6-minute walking test distance was 347.9 +/- 33.7 meters and 15 patients (75%) had a functional capacity of NYHA Class III, at the time of admission. ES was diagnosed with catheterization in all patients and mean systolic pulmonary arterial pressure measured by catheterization was 112 +/- 6.8 mmHg. Pulmonary function tests, FVC (forced vital capacity), FEV1 (forced expiratory volume), FEV1/FVC values were respectively, 3.1 +/- 0.4, 2.5 +/- 0.4 L and 76.7 +/- 3.3%. Metabolic tests were performed in all patients at the first visit. Mean VO2 max was 16.7 +/- 1.0 ml / kg/min and VE/VCO2 rate was 53.9 +/- 3.2%. Although PH and partial pressure of carbon dioxide levels were within normal range in blood gas analysis, oxygen saturation and partial pressure of oxygen levels were low. Conclusion: The most common underlying heart disease of ES patients is VSD. In this cases exercise capacity is restricted and this restriction is reflected in laboratory parameters.

Recently, left ventricular assist device (LVAD) implantation has been increasingly used in reducing pulmonary artery pressure (PAP) in patients with PH unresponsive to medical therapy. Herein, we aimed to compare the efficacy of continuous-flow and pulsatile-flow blood pumps on the improvement of PH in mechanical circulatory support patients. Twenty-seven patients with end-stage heart failure who underwent LVAD implantation surgery were enrolled. Fifteen of them (55.6%) had continuous-flow pump (HeartWare Ventricular Assist System, HeartWare, Inc., Miramar, FL, USA), and 12 of them (44.4%) had pulsatile pump (Berlin Heart EXCOR ventricular assist device, Berlin Heart AG, Berlin, Germany). The efficacy of LVADs on the improvement of PH was compared between continuous-flow and pulsatile pumps by the evaluation of systolic PAP, tricuspid annular plane systolic excursion (TAPSE), right ventricular systolic motion (RVSM), right ventricular ejection fraction (RVEF), and grade of tricuspid insufficiency (TI) for each of the study participants. All of the 15 patients who underwent continuous-flow blood pump implantation surgery (Group 1) were male with a mean age of 46.9 +/- 11.7 years, and in pulsatile-flow blood pump implanted participants (Group 2), the mean age was 40.6 +/- 16.8 years, all of whom were also male (P=0.259). Mean follow-up was 313.7 +/- 241.3 days in Group 1 and 448.7 +/- 120.7 days in Group 2 (P=0.139). In Group 1, mean preoperative and postoperative systolic PAP were measured as 51.7 +/- 12.2mmHg and 22.2 +/- 3.4mmHg, respectively, while those in Group 2 were 54.5 +/- 7.5mmHg and 33.9 +/- 6.4mmHg, respectively. A significantly greater decrease in systolic PAP was noticed in patients with continuous-flow blood pumps (P=0.023); however, no statistically significant difference was found when we considered the change in TAPSE between study groups (P=0.112). A statistical significance in the alteration of RVEF, RVSM, and the grade of TI during study visits was not found between the study groups (P=0.472, P=0.887, and P=0.237, respectively). Although the two studied types of LVADs were found to be effective in reducing PAP in heart transplantation candidates with PH, lesser postoperative systolic PAP values were achieved in patients who underwent continuous-flow pump implantation surgery.Öğe Complement consumption during cardiopulmonary bypass: comparison of Duraflo II heparin-coated and uncoated circuits in fully heparinized patients(Sage Publications Ltd, 1996) Hamulu, Ahmet; Discigil, Berent; Ozbaran, Mustafa; Calkavur, Tanzer; Kara, Erkan; Kokuludag, Ali; Buket, Suat; Bilkay, OnolHeparin attachment to synthetic surfaces is one means of improving the biocompatibility of clinically used cardiopulmonary bypass (CPB) circuits. To assess the effect of heparin-coated circuits on complement consumption during CPB, 40 patients undergoing elective myocardial revascularization were prospectively randomized either to a group in which a completely Duraflo II heparin-coated circuit was used for perfusion (heparin-coated Group, n = 20 patients) or to a control group (n = 20 patients) in which an uncoated, but otherwise standard circuit was used. Full systemic heparinization was induced (activated clotting time, 480 seconds) in all the patients included in the study, regardless of which perfusion circuit was used. The two groups did not differ significantly in terms of bodyweight, aortic crossclamp and extracorporeal circulation times. No patient had difficulty in weaning from bypass and the postoperative period was uneventful in all patients. Concentrations of C3 and C4 were found to be within the 'normal' range in the prebypass period in both groups. There were no significant intergroup differences with regard to C3 and C4 consumption during CPB. We conclude that Duraflo II heparin-coated circuits have no effect in reducing complement consumption during CPB in fully heparinized patients.Öğe Depression and anxiety levels of the mothers of children and adolescents with left ventricular assist devices(Wiley-Blackwell, 2012) Ozbaran, Burcu; Kose, Sezen; Yagdi, Tahir; Engin, Cagatay; Erermis, Serpil; Yazici, Kemal Utku; Noyan, Aysin; Ozbaran, MustafaOzbaran B, Kose S, Yagdi T, Engin C, Erermis S, Yazici KU, Noyan A, Ozbaran M. Depression and anxiety levels of the mothers of children and adolescents with left ventricular assist devices. Abstract: VADs have been used to provide treatment for end-stage heart failure. Parents may feel overwhelmed with the VAD regimes responsibility and be affected from this process beside children. In this study, we aimed to evaluate the depressive and anxiety symptoms of mothers of the first eight children equipped with a VAD in Turkey. The mothers of eight pediatric patients living with VADs were filled BDI and STAI at first month of VAD implantation (E.I) and secondly six months after their first evaluation (E.II). In E.I, the BDI mean score of mothers was 20.87, in E.II 14.37. STAI-S mean score was 53.37 in E.I and 43.62 in E.II. The Wilcoxon nonparametric-paired t-test revealed significant difference between baseline and end-point STAI-S scores (Z: -2.035; p: 0.042), and for BDI scores (Z, -1.965; p, 0.049). Prolonged usage of VAD may increase distress in parents. Psychiatric evaluation and support of the primary caregiver is important for the well-being of the pediatric patients.Öğe The detection of cardiac tamponade by hemodynamic transesophageal echocardiography after left ventriculer assist device implantation(Turkish Soc Cardiology, 2015) Kursun, Mustafa; Nalbantgil, Sanem; Ertugay, Serkan; Engin, Cagatay; Yagdi, Tahir; Ozbaran, MustafaÖğe The detection of cardiac tamponade by hemodynamic transesophageal echocardiography after left ventriculer assist device implantation(Turkish Soc Cardiology, 2015) Kursun, Mustafa; Nalbantgil, Sanem; Ertugay, Serkan; Engin, Cagatay; Yagdi, Tahir; Ozbaran, MustafaÖğe The detection of cardiac tamponade by hemodynamic transesophageal echocardiography after left ventriculer assist device implantation(Turkish Soc Cardiology, 2015) Kursun, Mustafa; Nalbantgil, Sanem; Ertugay, Serkan; Engin, Cagatay; Yagdi, Tahir; Ozbaran, MustafaÖğe Diagnostic Performance of Late Gadolinium Enhancement Analysis of Cardiac Magnetic Resonance Imaging in Monitoring Acute Cardiac Allograft Rejection(Elsevier Science Inc, 2013) Simsek, Evrim; Nalbantgil, Sanem; Ceylan, Naim; Zoghi, Mehdi; Nart, Deniz; Kursun, Mustafa; Engin, Cagatay; Yagdi, Tahir; Ozbaran, Mustafa
