Congenital coronary artery anomalies presenting in late adulthood with concurrent acquired heart disease: report of two cases.

ABSTRACT

Congenital coronary anomalies can be found in up to 1% of patients undergoing angiography. The most severe of these lesions become symptomatic in early childhood, while others can remain without consequence. However, while being silent in the early decades of life, these asymptomatic anomalies can contribute to the presentation of acquired heart disease and can themselves become clinically significant. We describe the clinical course of two patients with congenital coronary artery anomalies presenting beyond the fifth decade of life with concurrent acquired heart disease.
