A constellation of cardiac anomalies: Beyond shone's complex

Abstract

Shone's anomaly is a very rare congenital cardiac malformation characterized by four serial obstructive lesions of the left side of the heart (i) Supravalvular mitral membrane (ii) parachute mitral valve (iii) muscular or membranous subaortic stenosis and (iv) coarctation of aorta. We report a unique presentation of Shone's complex in a 14-year-old adolescent male. In addition to the four characteristic lesions the patient had bicuspid aortic valve, aneurysm of sinus of valsalva, patent ductus arteriosus, ventricular septal defect, persistent left superior vena cava opening into coronary sinus and severe pulmonary artery hypertension. This case report highlights the importance of a strong clinical suspicion of the coexistence of multiple congenital cardiac anomalies in Shone's complex and the significance of a careful comprehensive echocardiography.
