Key result
CMR identifies rare quadricuspid pulmonary valve alongside a 47 mm left pulmonary artery aneurysm.
Why the study?
Pulmonary valve and pulmonary artery abnormalities are difficult to visualize with cardiac ultrasound, and most descriptions come from autopsy series, limiting clinical detection.
Case Report (n=1)
Raises awareness of rare pulmonary anomalies in asymptomatic adults; extends case literature but leaves natural history and management open.
We present a coincidental finding of quadricuspid pulmonary valve and left pulmonary artery aneurysm. As both the pulmonary valve and the pulmonary trunk with its main branches are hard to visualise with cardiac ultrasound, most abnormalities described so far are from autopsy series. With the increasing use of CMR and its excellent potential for visualising both pulmonary valve and pulmonary arteries, we believe more cases will be discovered in the near future. Although pulmonary artery aneurysm are rare, timely detection may prevent lethal bleeding.

Nollen et al. (2011) conducted a case report in Quadricuspid pulmonary valve and left pulmonary artery aneurysm (n=1). Cardiovascular magnetic resonance imaging (CMR) was evaluated. Cardiovascular magnetic resonance imaging identified a rare combination of a quadricuspid pulmonary valve and a 47 mm idiopathic left pulmonary artery aneurysm in an asymptomatic 58-year-old man.
