title: First application of coronary flow reserve measurement for the assessment of left main compression syndrome in pulmonary hypertension.
abstract: Left main compression syndrome (LMCS) refers to extrinsic compression of the left main coronary artery because of a dilated pulmonary artery trunk. The condition represents an unusual cause of angina, left ventricular dysfunction, and sudden cardiac death in patients with pulmonary hypertension. We present 2 patients with the syndrome who were followed with serial assessments of coronary flow reserve by transthoracic echocardiography to screen for LMCS-related ischemia.
