The median age and weight at operation were 0.15 (range 0.01\u201313.1) years and 4.4 (range 3\u201313.1) kg, respectively. Survival was 100% at the medi follow-up of 12.6 (range 1\u201319.2) years. All patients showed normal left ventricular ejection fraction on transthoracic echocardiogram. In 1 patient, kinking of the proximal left circumflex artery resulted in non-significant obstruction. In all other cases, follow-up catheter angiography revealed unobstructed coronary arteries.
