Bicuspid Pulmonic Valve and Pulmonary Artery Aneurysm

Carlos A. Jamis-Dow, George H. Barbier, Mary P. Watkins, Gregory M. Lanza, Shelton D. Caruthers, Samuel A. Wickline


Bicuspid pulmonary valves and pulmonary artery aneurysms are two rare entities, reported in association, and usually attributed to hemodynamic alterations caused by the bicuspid pulmonary valve. We present magnetic resonance images of a patient with a bicuspid pulmonary valve and pulmonary artery aneurysm, and propose an alternative mechanism for this association, based on recent embryologic studies that link anomalies of the semilunar valves and great vessels with derangement of the cardiac neural crest cell development.
