Spectrum of coronary anomalies and their categorical approach: rare case series.

The incidence of coronary artery anomalies (CAAs) is 0.2-1.2% of the population. Its paradox of being a rare entity with presentation ranging from sudden cardiac death, congestive heart failure, myocardial infarction to being clinically silent, asserts a challenge to its treating physician. Among the various major categories of CAA, we describe four different types of these anomalies in our retrospective evaluation over 2 years. They include - coronary cameral fistula with coronary aneurysm, congenital atresia of left main, anomalous aortic origin of left anterior descending (LAD) and circumflex artery (LCx) with malignant LAD course, anomalous origin of left coronary artery from pulmonary artery (ALCAPA). Although the child with ALCAPA succumbed despite every possible and available timely efforts, other patients had good postoperative recovery and a brief hospital stay.
