Abstract
|
|
Introduction:
Congenital anomalies of the coronary artery have an incidence of 1% and isolated single coronary artery without other congenital cardiac anomalies has an approximate incidence of 0.024–0.066% in general population. This rare entity can be diagnosed incidentally during life, however may lead to symptomatic or asymptomatic myocardial infarction and sudden heart attack, even among young athletes. The prognosis varies according to the anatomic distribution, associated atheromatous disease and associated vascular anomalies.
Case Report: A 45 years old male with presentation of a single coronary artery from the right coronary sinus with subsequent coursing between the aorta and pulmonary trunk arteries and mid anterior descending artery segment course through the myocardium. Patient presented with non-typical angina symptoms, normal resting electrocardiograph, myocardial perfusion scintigraphy suspect to reduced left ventricular blood flow but negative angiographic evaluation. Conclusion: Thin bridges cannot be demonstrable angiography, so anatomic and panoramic CT-evaluation give more information especially if associated with functional evaluation. Knowledge of physiology, normal and variant anatomy, is most important in managing congenital and acquired disease, and variation in coronary arterial patterning is frequent. | |
