[Giant pulmonary artery aneurysm: etiology and an exceptional 17 years natural course]. / Anévrisme géant de l'artère pulmonaire : aspects étiologiques et évolutifs exceptionnels sur 17ans.

ABSTRACT

True pulmonary artery aneurysm (AAP) is rare and represent less than 1% of intra-thoracic aneurysms. We report a case of a AAP in a patient with a likely cor triatrium sinister, with an obstructive membrane responsible for pulmonary hypertension, explaining AAP. The long-term evolution of 17 years is made to an uncomplicated myocardial infarction. The patient died eight months later suddenly probably due to the rupture of the PAA.
