Obstructive teratoma in the right ventricle of a newborn: a case report.

Background: A newborn was diagnosed by echocardiogram with an asymptomatic cardiac mass in the right ventricle after a systolic cardiac murmur was detected at birth.

Case Presentation: Nine days after birth, the newborn presented with three syncopal episodes and oxygen desaturation which required resuscitation. The mass induced a complete right ventricular outflow tract obstruction.

Cardiac ochronosis: not so benign.

A 78-year-old patient with ochronosis has developed symptomatic aortic stenosis. He has undergone an aortic valve replacement that was highly complicated by a severe aortic calcification. The right coronary artery was sacrificed and bypassed in order to control a massive aortic root haemorrhage.
