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. Here, we report a 25-year-old male with DOLV with pulmonary stenosis and patent ductus arteriosus who presented to us with hemoptysis, which was due to respiratory tract infection. He improved with standard therapy.
