Transthoracic echocardiography evaluation of double outlet left ventricle: Unique case report and review of literature

Double-outlet left ventricle (DOLV) is a rare cardiac malformation in which both great arteries originate from the morphological left ventricle. DOLV is associated with high mortality, generally due to heart failure, myocardial infarction, or aortic thrombosis. With surgery, the 5-year survival rate is estimated at 70%–75%. Most patients will continue to present with residual cardiac anomalies, such as aortic or mitral valve regurgitation, arrhythmias, or hypertension. We are reporting a complex case of cyanotic congenital heart disease in a 5 month old female infant suffering from DOLV, who presented to us with recurrent chest infections and bluish colouration of skin.
