Review of variations in origin of left circumflex coronary artery.
نویسندگان
چکیده
During the performance of 200 routine coronary angiograms, 5 patients with anatomical variants of the origin of the left circumflex coronary artery were found. The origin and course of the left circumflex coronary artery is described in each case. The practical importance of these variant vessels in patients being considered for coronary artery surgery is emphasized.

Congenital 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...
متن کاملClinical 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 کاملThe Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery (ALCAPA): a Case Series and Brief Review
Background Anomalous left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital cardiovascular defect that occurs in approximately 1/300 000 live births or 0.5% of children with congenital heart disease. There are two types of ALCAPA syndrome: the infant type and the adult type. The most infants experience myocardial infarction and congestive heart failure, and approximately 9...
متن کاملCoronary artery bypass surgery in patients with anomalous circumflex artery.
The anomalous origin of the circumflex artery (Cx) is uncommon and presents course variations that might make the coronary artery bypass surgery (CABG) difficult. Two patients presenting unstable angina were submitted to coronary angiography that disclosed tri-vessel disease and presence of Cx with an anomalous origin and retroaortic course with severe stenosis. Both patients underwent CABG wit...
متن کاملPrevalence of congenital coronary artery anomalies and variants in 726 consecutive patients based on 64-slice coronary computed tomography angiography.
BACKGROUND Coronary computed tomography angiography (CCTA) is helpful in making a precise noninvasive evaluation of coronary anatomy, allowing concomitant evaluation of other cardiac structures. The aim of this study was to determine the prevalence of coronary artery variations detected by 64-slice multi detector CT. MATERIALS AND METHODS The results of ECG-gated CCTA in 726 consecutive patie...
