Acquired cor triatriatum after orthotopic cardiac transplantation.
Orthotopic cardiac transplantation was performed in a 42-year-old woman with idiopathic cardiomyopathy. Postoperative right ventricular failure developed and a transesophageal echocardiogram demonstrated acquired cor triatriatum with marked obstruction to mitral valve inflow and severe right ventricular dilatation. At reexploration, redundant donor atrial tissue was excised correcting the cor triatriatum. She was alive and well with normal hemodynamic parameters 12 months after transplantation.
