Pulmonary hypertension causing left main coronary artery compression

Left main coronary artery compression by an enlarged pulmonary artery.

Left main coronary artery to left atrial fistula causing mild pulmonary hypertension.

A73-year-old man with a 6-month history of exertional chest tightness and dyspnea was referred for evaluation. No risk factors for coronary atherosclerosis were present. Left cardiac catheterization revealed coronary arteries without significant stenoses and mildly impaired left ventricular function (ejection fraction, 55%). A fistula from the main stem of the left coronary artery to the left a...

Left main bronchus compression due to main pulmonary artery dilatation in pulmonary hypertension: two case reports.

Pulmonary arterial dilatation associated with pulmonary hypertension may result in significant compression of local structures. Left main coronary artery and left recurrent laryngeal nerve compression have been described. Tracheobronchial compression from pulmonary arterial dilatation is rare in adults, and there are no reports in the literature of its occurrence in idiopathic pulmonary arteria...

[Stenting in primary pulmonary hypertension with compression of the left main coronary artery].

Primary pulmonary hypertension is often associated with angina-like chest pain of uncertain etiology. Left main coronary artery compression by the pulmonary artery is a treatable cause of angina and should be considered in these patients. We describe a patient presenting with primary pulmonary hypertension, clinical angina and extrinsic compression of the left main coronary artery by the pulmon...

Severe Compression of the Left Main Coronary Artery in a Patient with Chronic Thromboembolic Pulmonary Hypertension.

Extrinsic compression of the left main coronary artery (LMCA) can occur in patients with an enlarged pulmonary artery trunk secondary to severe pulmonary hypertension (PH). This phenomenon rarely occurs in PH; moreover, few reports have shown that chronic thromboembolic PH can be a triggering factor for this syndrome. Herein, we describe a patient with extrinsic compression of the LMCA with chr...
