Segmental diastolic compression of circumflex coronary artery secondary to pericardial constriction: an uncommon cause of angina pectoris.

Diastolic segmental compression of a native coronary artery is an uncommon cause of chest pain. Here we describe a 24-year-old woman with constrictive pericarditis who had retrosternal chest pain, progressive dyspnea, tachycardia, and bilateral leg edema. She was diagnosed with compression of the first and second obtuse marginal branches of left circumflex coronary artery secondary to constrictive pericarditis. She underwent pericardiectomy and her symptoms were relieved following surgery.
