Abstract
ABSTRACT Isolated stenosis of the left coronary artery is extremely rare. Studies have shown a 2%–10% incidence of acute myocardial infarction in patients aged 45 years or younger. Stable angina and multivessel disease are uncommon in the young. It is more commonly reported in postmenopausal women. Here, we describe a 30-year-old female who presented to the emergency department with angina. Coronary angiography (CAG) was suggestive of isolated left main coronary artery (LMCA) ostial disease with rest of the coronaries normal. Computed tomography CAG performed with a calcium score of 0 revealed isolated osteoproximal stenosis of the LMCA. The patient was extensively evaluated for all risk factors but was devoid of any. Coronary artery bypass grafting was performed without complications.
