Abstract
Introduction: coronary arteries anomalies are congenital. Usually, they are asymptomatic. they are found during the coronary angiography or computed tomography angiography. the most common coronary anomaly is separated origin of left anterior descending coronary artery and left circumflex artery coronary artery. Usually, it is a benign anomaly. case report: A 54-year-old male was admitted at the service of cardiology. twenty-five years ago he was diagnosed with mitral stenosis and five years ago as having a thrombotic cerebrovascular accident. Electrocardiogram showed atrial fibrillation trans-thoracic echocardiography showed calcified mitral stenosis, with an anatomical area of 1.1 cm 2 . the patient was treated with oral anticoagulants (acenocumarol), beta-blockers (atenolol), and diuretics (hydrochlorothiazide plus spironolactone). the patient underwent coronary angiography which showed a 75% stenosis of the right coronary artery. the origin and course of right coronary artery was abnormal and thus a ct angiography was performed. the ct angiography confirmed that the origin of the right coronary artery was
Highlights
They are found during the coronary angiography or computed tomography angiography
The CT angiography confirmed that the origin of the right coronary artery was from the left coronary sinus and that the artery coursed between the aorta and the pulmonary artery
It remains unclear whether mitral stenosis was congenital or rheumatic in origin or whether there is any causal relationship between the coronary artery anomaly and mitral stenosis
Summary
Coronary artery anomalies are present at birth. They are usually asymptomatic. A higher incidence of coronary artery anomalies in young versus old people with sudden cardiac death has been reported. Coronary artery anomalies are the second most common case of sudden death in young athletes, after hypertrophic cardiomyopathy. The CT angiography confirmed that the origin of the right coronary artery was from the left coronary sinus and that the artery coursed between the aorta and the pulmonary artery (Figure 3 and Figure 4) Under these circumstances, the patient was transferred to cardiac surgery where the mitral valve replacement and coronary artery bypass graft surgery (between aorta and right coronary artery) were performed. 3) spasm of coronary artery as a result of endothelial injury [1,2,3,4] This anomaly is associated with sudden death in young athletes during exercise. The right coronary artery stenosis was mechanical (compressive) [1,2,3,4,5]
