A case of congenital left ventricular diverticulum in an adult patient

Abstract

Abstract Congenital left ventricular diverticulum (CL.koVD) refers to a localized cystic protrusion of the ventricular wall that interacts with the heart cavities through a narrow channel and is a rare heart malformation. In recent years, many cases of this disease involving infants and children have been reported, while few cases involving adults have been described. The case of an adult with CLVD who underwent successful surgery was retrospectively evaluated. The echocardiography examination indicated that the apical myocardium of the left ventricle was thin and bulging outward and that the contractile movement was significantly reduced. During the surgery, it was observed that the left ventricle was enlarged, and a left ventricular diverticulum structure was observed on the left side of the apex. A bovine pericardial patch of the corresponding size was used to continuously suture and repair the internal orifice of the diverticulum. The postoperative pathology revealed that the resected sample was composed of full myocardial tissue. This report focused on the imaging characteristics of left ventricular diverticula to improve the understanding of CLVD. With its simple, economical, and noninvasive characteristics, echocardiography presents the best option for diagnosing a ventricular diverticulum.
