Left Main Coronary Artery Compression by an Enlarged Pulmonary Artery

Left main coronary artery compression by an enlarged pulmonary artery.

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.

Systolic compression of left main coronary artery by left ventricular pseudoaneurysm complicated by critical stenosis of left main coronary artery

A 69-year-old man was admitted to the hospital with complaints of exertional substernal chest pain and dyspnea for 3 weeks. His medical history consisted of dyslipidemia, type 2 diabetes mellitus, and valvular heart disease. He had a mitral commissurotomy through a left thoracotomy for mitral stenosis at age 16 years followed by mitral valve replacement with a 25 mm Carpentier Edwards bovine pe...

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...

A Case of Extrinsic Compression of the Left Main Coronary Artery Secondary to Pulmonary Artery Dilatation

Extrinsic compression of the left main coronary artery (LMCA) secondary to pulmonary artery dilatation is a rare syndrome. Most cases of pulmonary artery hypertension but no atherosclerotic risk factors rarely undergo coronary angiography, and hence, diagnoses are seldom made and proper management is often delayed in these patients. We describe a patient that presented with pulmonary hypertensi...
