Abstract

Background Bicuspid pulmonic valves are quite uncommon, being described in only 0.1% of donor hearts, while pulmonary artery aneurysms are even more rare, having been found in 8 out of 109,571 autopsies. This rarity makes it difficult to characterize the relationship between them. Materials & Methods We describe the case of a 66-year-old female who was found to have a bicuspid pulmonic valve and pulmonary artery aneurysm (5.1cm) on imaging by her cardiologist. Discussion & Conclusion This case raises the question of whether the association between bicuspid semilunar valve disease and vascular wall anomalies are more genetic or hemodynamic. Even on the aortic side, despite the robust association between bicuspid aortic valves and thoracic aortic aneurysms, the mechanism still remains unclear. In our patient there was no significant gradient across the bicuspid pulmonic valve, suggesting that hemodynamics are not the primum mobile of this association.
