Congenital Left Ventricular Outpouching ( Lvo ) - 1685 Words

Congenital left ventricular outpouching (LVO) is an uncommon perinatal diagnosis. Various terms used in the medical literature to describe the LVO are a source of perplexity. The novel classification developed in a recent review by Rad et al attempting to provide a clear differentiation of the mixed definitions based on anatomical and cardiac imaging data. Our report presents a case series of prenatal diagnosis of LVO. The application of Rad et al original classification and its impact on the patients’ outcome are discussed. Introduction: Congenital left ventricular outpouching (LVO) is a rare disorder in which a confined protrusion arises from the left ventricular (LV) free wall. The terms LV aneurysm, LV diverticulum, double-chambered LV and LV accessory chamber have been used interchangeably in the literature [1–9], however anatomical differences do exist between these terms [10]. LV aneurysm is an expansible thin-walled, usually fibrotic myocardium and pericardium, pouch contracting in asynchrony with the LV and has a wide communication with the LV cavity. Conversely, an LV diverticulum has three cardiac wall layers (endocardium, myocardium and pericardium), contracts in synchrony with the LV and has a narrow connection to LV. LV accessory chamber presents an entity that combines some criteria of both aneurysm and diverticulum. Its wall is similar to a diverticulum but it has a wide communication with the LV as an aneurysm. Lastly, double-chambered leftShow MoreRelatedCongenital Left Ventricular Outpouching ( Lvo )1782 Words   |  8 PagesIntroduction: Congenital left ventricular outpouching (LVO) is a rare disorder in which a confined protrusion arises from the left ventricular (LV) free wall.
