Left ventricular diverticulum: A case report and review of the literature

“…Some authors divided the left ventricular diverticulum into muscle type and fiber type. Others divided it into 2 groups based on diverticulum location: the apical type, always associated with other congenital heart abnormalities, and the non-apical type [2 , 5 , 11] . The diverticulum can be congenital or acquired.…”

“…LVD is often discovered incidentally during an examination of other organs, based on echocardiography, cardiac magnetic resonance, and cardiac MSCT. On echocardiography, a tubular structure or a sac communicating with the ventricles is seen, usually originating from the heart apex, with flow signal inside, contraction according to the left ventricular rhythm [5] . On cardiac MSCT, diverticula may have different shapes and sizes, but most are tubular structures, communicating with the ventricles.…”

“…On MRI, the diverticulum has the same signal as the ventricle, with synergistic contraction of the ventricular muscle. Some small diverticula may collapse during ventricular systole [5 , 8 , 17] . No signal change or abnormal enhancement, no necrosis or fibrosis is seen [8] .…”

“…Congenital left ventricular diverticulum (LVD) is a rare congenital anomaly with a prevalence of 0.4% or 3 in 750 cardiac death autopsies [1] , [2] , [3] . A left ventricular diverticulum is defined as an enlarged structure containing the endocardium, myocardium, and pericardium and displays normal systolic contraction [4 , 5] . The left ventricular diverticulum is often diagnosed during early childhood because it is frequently associated with other cardiac and midline thoracoabdominal anomalies.…”
