This case report describes a rare congenital diverticulum of the heart arising from the coronary sinus in a neonate with hypoplastic left heart.
A diverticulum originating from the coronary sinus was diagnosed by echocardiography in a two day old baby with hypoplastic left heart. At necropsy the diverticulum was seen to arise from the coronary sinus and it penetrated the right ventricular posterior wall.
Segni et al. (Wed,) studied this question.
