the anomalous origin of the right coronary artery (rca) as a branch from the left anterior descending artery (lad) is a very rare variation of the single coronary artery anomaly. the anomalous vessel arises from the proximal or midportion of the lad and courses anterior to the pulmonary artery trunk in most instances. in this case report, a 61-year-old woman is introduced who underwent coronary...

origination of the right coronary artery (rca) from the left anterior descending (lad) artery is a case of single coronary artery. it is an extremely rare coronary artery abnormality and usually an incidental finding during coronary angiography. a 73-year-old man with a medical history of hypertension arrived with chest pain. medical therapy started for st elevated myocardial ischemia. during h...

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...

detection of causes of sudden natural death is a major problem of physicians and exact inspection of rare causes of sudden death reduces numbers of white autopsies and helps to well performance of justice. anomalous origin of coronary arteries are one of these rare cases that mostly in infants leading to death due to ischemia and heart failure , and sometimes survive until adulthood and attenti...

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...

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...

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital cardiac malformation. We report three cases of ALCAPA who survived to adulthood. The first case was a 51-year-old woman who complained of typical chest pain that was diagnosed with ALCAPA using cardiac catheterization and coronary computed tomographic angiography (CTA). The second case was a 30-...

BACKGROUND Most coronary artery anomalies are congenital in origin. This study angiographically determined the prevalence of different forms of anomalous aortic origins of coronary anomalies and their anatomic variation in a selected adult Lebanese population. Correlation between these anomalies and stenotic coronary atherosclerotic disease was also investigated. METHODS 4650 coronary angiogr...
