Acute Myocardial Infarction of the Right Coronary Artery Originating From the Distal Left Circumflex Artery

Abstract

A case of acute myocardial infarction (AMI) of the distal left circumflex, near the origin of an aberrant right coronary artery is presented. Coronary stenting was successfully performed. According to several reports, this anomaly is a common site for coronary atherosclerosis, but this is the first report of AMI. (Circ J 2008; 72: 2092 -2095

Ramus Circumflexissimus-A Rare Coronary Anomaly Detected by Coronary Computed Tomography Angiography

“…Like our patient, most patients who reported did not develop symptoms or signs of cardiac dysfunction 6–15 . However, because the entire heart is supplied by an SCA, the occurrence of atherosclerosis or other pathology in the coronary artery carries an increased risk in these patients 16–19 . Even in the absence of coronary atherosclerosis or thrombosis, ventricular tachycardia and sudden death have both been described in infants as well as in adults with L‐1 type single coronary artery.…”

“…[6][7][8][9][10][11][12][13][14][15] However, because the entire heart is supplied by an SCA, the occurrence of atherosclerosis or other pathology in the coronary artery carries an increased risk in these patients. [16][17][18][19] Even in the absence of coronary atherosclerosis or thrombosis, ventricular tachycardia and sudden death have both been described in infants as well as in adults with L-1 type single coronary artery. The relationship between the coronary anomaly and the clinical picture in these patients remains unclear, and is not supported by evidence of ischemia or infarction in these reports.…”

Successful Percutaneous Coronary Intervention for Anomalous Coronary Artery Origin

“…Koroner arter anomalilerine bağlı miyokart iskemisi, koroner arterlerin doğuştan atrezisi veya darlığı, koroner arterin pulmoner arterden çıkması, anormal seyri veya koroner fi stül olgularında koroner çalma sendromuna yol açarak oluşabileceği gibi, bu anomalilerin üzerine eklenen vazospazm veya aterosklerotik darlığa bağlı olarak da gelişebilmektedir. Çeşitli çalışmalarda, kardiyak kateterizasyon yapılan hastaların yaklaşık %1-2'sinde KAA saptanmıştır (1,6) . Anomalili anatominin doğru görüntülenmesi, hastaların tedavisinin uygun bir biçimde planlanması açısından önem taşımaktadır.…”
