Coarctation of persistent right fifth aortic arch and pulmonary sequestration

Abstract

AbstractA 41-day-old boy was transferred to our department with severe congestive heart failure. Digital subtraction counter current aortography, and antegrade aortography, revealed coarctation of a persistent right fifth aortic arch, stenosis of the origin of an aberrant left subclavian artery, and sequestration of the lower lobe of the right lung.As his heart failure seemed to be caused not only by pressure overload to the left ventricle following coarctation, but also by the volume load associated with the shunting effect of the pulmonary sequestration, we performed transcatheter balloon dilation of the coarctation and the origin of the aberrant subclavian artery, together with embolization of the aberrant pulmonary artery. His heart failure responded dramatically to these procedures.
