An Isolated Congenital Left Ventricular Diverticulum with Mitral Valve Endocarditis

Congenital left ventricular diverticulum is a rare cardiac malformation, which could result in rupture, thrombosis, congestive heart failure, infective endocarditis, ventricular arrhythmia and aortic insufficiency. Most authors propose that patients who are symptomatic and have a higher risk for major complications should undergo surgical treatment. We present a case of isolated congenital left ventricular diverticulum with mitral valve infective endocarditis and anomalous single coronary artery observed intra-operatively. The patient underwent successful surgical repair of the diverticulum by continuous suture of the internal opening inside the left ventricle.
