RESUMO
Helical computed tomographic angiography with differential color imaging technique clearly demonstrated pulmonary venous obstruction in an infant with total anomalous pulmonary venous drainage before and after operation. This technique is less invasive and provides precise spatial information of complicated vascular anomalies.

We evaluated the change of coronary flow reserve using a Doppler guidewire before and after coronary artery bypass grafting to assess the coronary hemodynamic effect of surgical revascularization in a 13-year-old boy with congenital atresia of the left coronary ostium, which is one of the rarest of the congenital coronary anomalies. Coronary flow reserve in the right coronary artery and left anterior descending artery increased significantly after coronary revascularization, and a microvascular bed developed in the left anterior descending artery.
