Abstract：Objective To assess the diagnosic value of echocardiography in congenital left coronary artery atresia (LCAA).Methods The echocardiographic characteristics of 3 hospitalized cases with LCAA were analyzed retrospectively and compared with angiographic results and surgical findings.Results Two cases were reminded correctly, the other case was misdiagnosed as severe mitral regurgitation.The characteristics of the echocardiography in 3 cases were absence of the left coronary artery ostium from the left coronary sinus, dialation of right coronary artery, moderate to severe mitral regurgitation, increasing echogenicity of the papillary muscles and collateral vessels in septum.Compared with the elder patient, 2 infant patients had poorer left cardiac function and less intercoronary collateral circulation.Conclusion Echocardiography, as a noninvasive method, could reveal congenital atresia of the left coronary artery, and provides more evidence for the further investigation and treatment.
