Left main coronary artery and right pulmonary vein compression by a large pulmonary artery aneurysm

Left main coronary artery and right pulmonary vein compression by a large pulmonary artery aneurysm.

Pulmonary artery aneurysms are uncommon and may be associated with significant morbidity and mortality. The unique combination of left main coronary artery and upper right pulmonary vein compression by a large pulmonary artery aneurysm is reported. Furthermore, the aetiology, clinical manifestations, complications, diagnostic approach, and possible therapeutic interventions are briefly discussed.

CASE REPORT Left main coronary artery and right pulmonary vein compression by a large pulmonary artery aneurysm

P ulmonary artery aneurysms (PAAs) are uncommon. Depending on their size and location, they may lead to complications such as extrinsic compression of the left main coronary artery and the upper right pulmonary vein, as we describe in our case. Other complications are thrombus formation, secondary thromboembolic phenomena, and rupture. Therefore, awareness of this condition and its diagnosis ar...

Left main coronary artery compression by an enlarged pulmonary artery.

Compression of the left main coronary artery by a giant pulmonary artery aneurysm.

We present a 70-year--old man who had a past medical history of dilated idiopathic pulmonary artery, incidentally diagnosed at the age of 23 years. He was asymptomatic until a year ago when he was admitted for an episode of anginal chest pain in the context of paroxysmal atrial fibrillation. At rapid rates, he showed pathological ST segment descent. A coronary angiography showed a slight stenos...

aneurysms of the left main coronary artery are exceedingly rare clinical entities, encountered incidentally in approximately 0.1% of patients who undergo routine angiography. the most common cause of coronary artery aneurysms is atherosclerosis. angiography is the gold standard for diagnosis and treatment. depending on the severity of the coexisting coronary stenosis, patients with left main co...
