Short Report

Abstract

Congenital mitral regurgitation is relatively rare. It can be due to congenital malformation of the valve apparatus, associated structural heart defects, or results from myocardial dysfunction leading to deformation of the valve annulus. Hence, careful delineation of the pathologic processes involved in the mechanism is critical when evaluating patients presenting with congenital mitral valve regurgitation. Congenital anomalies of the coronary system are one of the serious associations, which needs prompt recognition and treatment to prevent fatal complications. We report a case of congenital atresia of left main coronary artery in an asymptomatic 8-month-old presenting with an incidental finding of mitral valvar regurgitation. Appropriate investigations and management lead to restoration of normal coronary blood flow and valve function. This particular case illustrates that congenital coronary anomalies may present in an otherwise asymptomatic child. It should be considered as one of the possible differential diagnosis in unexplained mitral regurgitation. Early recognition and prompt surgical treatment can radically modify the prognosis.
