Pulmonary Artery Aneurysm and Coronary Artery Disease in a Patient with Previous Cardiac Surgery

Introduction

Pulmonary artery aneurysms (PAA) - that is, aneurysms with a diameter greater than 5 cm - are very rare lesions and can occur as central or as peripheral types [[1]]. Their cause and pathogenesis is not clear. Documented etiologies include primary or secondary pulmonary hypertension, pulmonary valve stenosis, infections, systemic disorders such as Behçet's syndrome and other congenital and acquired cardiovascular diseases [[2]]. Their natural history and management is controversial. The risk of rupture and dissection is higher in patients with high pulmonary artery pressures.

We present a patient with previous cardiac surgery, a large main, left and right PAA and coronary artery disease.
