The absence of the right superior vena cava in situs solitus is a rare anomaly. It is usually associated with persistence of the left superior vena cava or other cardiac abnormalities.1
We report here an extremely uncommon case of bilateral absence of the superior vena cava, with no associated cardiac anomaly, evaluated through a high-resolution computed tomography (CT) scan.
Clinical Summary
A 14-month-old boy was admitted to our department because of a cardiac murmur discovered during a routine pediatric evaluation. On physical examination, a systolic heart murmur of grade 1/6 to 2/6 was found. No chronic heart failure or syndromic dysmorphism had been found. The electrocardiogram showed sinus rhythm and no evidence of atrioventricular arrhythmia. A transthoracic echocardiogram found a situs solitus, levocardia with atrioventricular and ventriculoarterial concordance, normal-sized ventricles, normal intracardiac anatomy, and the inferior vena cava draining normally into the right atrium. No superior caval vein could be seen.
We performed cardiac CT scanning to confirm the
