Diverticulum or aneurysm of left ventricle

An Asymptomatic Left Ventricular Diverticulum

“…Diverticulum is often difficult to distinguish from aneurysm. As seen in our case, the wall of diverticulum is formed by endocardium, myocardium and pericardium, and contracts normally, whereas an aneurysm is a fibrous saccular lesion and contracts paradoxically (1,8). As in our case, many cardiac diverticulae are clinically silent, but they can cause ventricular disrhythmia, systemic embolisms, or ventricular rupture and sudden death (10,11).…”

“…A weakness of the myocardial wall during the embryogenesis may cause a focal protrusion of the ventricular wall (1).…”

Prenatally diagnosed left ventricular diverticulum with thoracoabdominal wall defect: a case and review of the literature

“…The terms "fibrous diverticulum" or "congenital aneurysm" refer to aneurysm whose etiology is unknown. It usually appears as an isolated anomaly (1,2).…”

“…It is important to differentiate this entity from the ectopia cordis in which no cardiac silhouette is found in the thorax of the chest roentgenograms. A true diverticulum may protrude beyond the thorax but the basic cardiac position remains normal (2).…”

Ventricular Tachycardia Originating from a Heart-shaped Idiopathic Left Ventricular Aneurysm Diagnosed on a Three-dimensional Electroanatomical Mapping System Integrated with CT Imaging

“…Other underlying acquired diseases, such as sarcoidosis, Chagas disease and myocarditis, can also cause this condition. On the other hand, idiopathic left ventricular epicardial pouches are rare cardiac malformations that are usually divided into two types, left ventricular diverticula (LVDs) and left ventricular aneurysms (LVAs), based on histological and morphological analyses (1,2). LVD is characterized by synchronal contractility and the presence of three myocardial layers on histological examination.…”
