The longest documented left main coronary artery/Dokumante edilmis en uzun ana koroner arter.

A 63-years old man with hypertension presented to our hospital with a complaint of resting chest pain. The patient was 180 cm high and weighed 100 kg. He was admitted to our clinic with a diagnosis of subacute anterior myocardial infarction. On the fifth day of hospitalization coronary angiography was planned. On coronary angiography, a long left main coronary artery (43 mm in length) was seen (Fig. 1). There were critically discrete stenoses at the proximal segment of left anterior descending coronary artery, at the midportion of the right coronary artery and at the proximal segment of the circumflex artery. On ventriculography the left ventricular sizes were normal, akinesia at the anterior and apical portion of the left ventricle, mild mitral regurgitation were seen. The ejection fraction was measured as 38% and coronary artery bypass graft operation was advised.

The left main coronary artery ranges from 3 to 6 mm in diameter and may be up to 10 to 15 mm in length in humans. In an anatomical study, the longest left main trunk was reported to be 23 mm long. The average length of the left main coronary artery was 10.8 [+ or -] 5.52 mm (range = 2-23 mm). The longest reported length was 38 mm. We have reported a patient with 43 mm in length left main coronary artery and subacute anterior myocardial infarction.
