An Extremely Rare Variety of Anomalous Coronary Artery: Right Coronary Artery Originating From the Distal Left Circumflex Artery
نویسندگان
چکیده
A single coronary artery (SCA) is a rare congenital anomaly of the coronary circulation, which is often associated with myocardial ischemia and other congenital cardiac anomalies. A 77-year-old woman visited our hospital complaining of typical chest pain. Coronary angiography revealed an isolated SCA. The right coronary artery did not originate from the aorta, but instead emerged from the distal left circumflex artery, with significant stenosis at the proximal portion of the left anterior descending artery. A stent was successfully implanted at the culprit lesion. There was no perfusion defect detected by a cardiac SPECT study.

Clinical Implications of Congenital Absence of Circumflex Coronary Artery
Introduction: Coronary artery anomalies are rare clinical entities reported in 0.6% to 5.6% of diagnostic coronary angiographies. Anomalous origins of coronary arteries from distal segments are rarely reported. Presented herein is a coronary anomaly in which the circumflex artery (CX) originated as a continuation of the posterolateral branch of the right coronary artery (RCA) w...
متن کاملCongenital Absence of Left Circumflex Coronary Artery
Congenital absence of left circumflex artery is a rare congenital anomaly of the coronary arteries. The prevalence of the anomaly in different studies ranges from 0.6% to 1.3%. Of these, 80% are benign and asymptomatic and 20% are clinically important. We report a 56-year-old man presented with acute resting chest pain who was diagnosed as having acute anterolateral infarction accompanied by el...

Single coronary arteries are rare congenital anomalies in which the whole heart circulation is supplied by a coronary artery arising from a single ostium. Single left coronary artery with right coronary artery (RCA) originating from distal left circumflex artery (LCX) is a very rare anomaly with only few cases reported in the literature. We report a 44 years old male presenting with anterior my...

The incidence of anomalous left circumflex coronary artery (LÇX) originating from the right cusp of aorta is a rare finding. Ït has prevalence rate of 0.30% to 0.37% which may be overlooked by Çardiologists, and may lead to the improper treatment of the patients. Here, a 50 years old woman with non specific complaint referred to the clinic is introduced.
