“…However, our case (by PAA diameter of 9.8 cm on echocardiography) can be considered as a huge idiopathic aneurysm compared to the highest reported cut-off for PA diameter. Approximately all patients with PAA present with dyspnea and palpitation [1, 3, 7, 9, 10]. In many cases presence of cardiac symptoms such as auscultation abnormalities or abnormal pulmonary artery in chest radiography raised the suspicion of pulmonary artery abnormality and echocardiography, CT scan, and angiography were further performed to confirm the diagnosis [3, 6, 10, 11].…”

“…Many medical conditions including congenital heart defects, connective tissue disorders, and pulmonary hypertension can cause PAA [1, 5]. However, idiopathic PAA is an infrequent and rarely reported lesion [3]. Noninvasive imaging techniques including magnetic resonance imaging (MRI) and CT can help clinician in diagnosis, but the gold standard diagnostic tool for PAA is pulmonary angiography [2, 4].…”

Idiopathic pulmonary artery aneurysm is a rare condition. This type of aneurysm can be presented with noncardiac symptoms or even asymptomatic. We report a 73-year-old man with a gigantic idiopathic pulmonary artery aneurysm which was referred to our unit for his kidney problems. During his workup we incidentally found the aneurysm by an abnormal chest-X ray and auscultation. Our further evaluations revealed a 9.8 cm aneurysm in transthoracic echocardiography.

“…2) Previous reports have demonstrated several underlying diseases that were considered as possible risk factors for the development of PAA: valvular pulmonary stenosis, congenital heart disease with intracardiac shunting, PAH, vasculitis, and connective tissue disorder. 3,4) The most commonly reported etiology of PAA is its association with congenital heart disease with a large left-to-right shunt and PAH. 5) In our patient, PS was treated with percutaneous transvenous pulmonary valve commissurotomy, and a transthoracic echocardiogram also showed no finding of valvular pulmonary stenosis.…”

Pulmonary artery aneurysm (PAA) is generally a rare lesion, and there is no definitive approach for it. We report the case of a 45-year-old man who was admitted for the evaluation of dyspnea. In childhood, he had been diagnosed with PAA with congenital pulmonary valve stenosis and regurgitation, and he had a percutaneous transvenous pulmonary valve commissurotomy. Transthoracic echocardiogram showed dilatation of the right atrium and right ventricle, with right ventricular hypertrophy. There was severe pulmonary valve regurgitation, and the main pulmonary artery was dilated to 68 mm in diameter. From the surgical findings, the left leaflet of pulmonary valve was torn from commissure with failure to coapt with the other leaflet. After direct sutures of edges of the left leaflet, a nearly normal valvular competence was restored. The PAA was repaired with a Y-shaped 24 × 12 mm Dacron graft replacement. The postoperative course was uneventful, and the patient was discharged.
