Case Summary: This 2 days old male baby was delivered by normal vaginal delivery without any complication. During routine physical examination, heart murmur was heard and cardiology was consulted for evaluation. His examination showed no dysmorphic features, normal vital signs, normal perfusion, normal first and second heart sounds and II/VI ejection systolic murmur at left sternal border. ECG and chest x-ray were normal and he was diagnosed clinically as a case of possible pulmonary stenosis. Echocardiogram showed (Fig.1 a and b) multiple cardiac tumors with different sizes (ranging from millimeters to centimeters) located in the free wall of both left and right ventricles and interventricular septum. One of these Rhabdomyomas was occupying the right ventricle outflow tract causing moderate subvalvar pulmonary stenosis. Heart Views 2007;8(3)112. © Gulf Heart Asosociation 2007.
