ABSTRACT: Major aortopulmonary collateral arteries (MAPCAs) are congenital vessels
that arise from the aorta or its first-order branches and are distally
connected to the pulmonary arterial vasculature, thereby providing pulmonary
blood flow. MAPCAs are often associated with cyanotic congenital heart disease
with decreased pulmonary blood flow. Isolated MAPCAs are rare in patients
without congenital heart disease with structurally normal hearts. Sometimes,
isolated congenital MAPCAs can occur without any lung disease. Isolated MAPCAs
represent the occurrence of collaterals in the absence of underlying heart
disease, which commonly presents as heart failure, recurrent respiratory tract
infection, and pulmonary artery hypertension. We report a rare case of
congestive heart failure in a 6-year-old patient with dual arterial supply to
an otherwise normal right lung, with a normal bronchial tree, and a
structurally normal heart. The patient was successfully managed by the closure
of collaterals by Amplatzer vascular plugs II (AVPII) and Amplatzer Piccolo Occluders.
