RESUMEN
Objective To investigate the characteristic and diagnosis of left ventricular diverticulum. Meth-ods As one left ventricular diverticulum patient was diagnosed by echocardiography in our hospital,we reviewed and analyzed about published in China. Results Left ventricular diverticulum is a rare disease of congenital heart malfor-marion, Echocardiographic characteristics of the left ventricular diverticulum is the saccular evngination of the left ven-tricular wall with the neck of the diverticula being smaller than the body. Left ventricular diverticulum is classified into contractile muscular type and fibrous type ,The saccular wall of contractile muscular diverticulum remain a normal mo-tion and is thinner than the normal wall The saccular wall of the fibrous diverticulum is due to a loss of myocardial thickness, as thin as aneurysm with a dyskinetic motion. Conclusion Left ventricular diverticulum is a rare disease in clinic, echocardiography is very important for diagnosing classifying.
