However, even if no annular enlargement procedure is performed, this complication may be encountered after isolated aortic valve replacement because of either extensive decalcification of the aortic annulus or progressive tension on the anterior leaflet of the mitral valve, caused by aortic valve sutures placed adjacent to firm or heavily calcified valve tissue. Routine transthoracic echocardiography may be inadequate for diagnosis of this condition; transesophageal echocardiography should be used both for preoperative diagnosis and for intraoperative management. We report the case of a patient who had severe mitral regurgitation that occurred after aortic valve replacement with a mechanical valve. © 2006 by the Texas Heart® Institute.eninfo:eu-repo/semantics/closedAccessAortic valve/surgeryCardiac surgical procedures/methodsEchocardiography, transesophagealHeart valve prosthesis/adverse effectsMitral valve insufficiency/etiology/ultrasonography/surgeryPostoperative complicationsArticle331545616572871Q3
