title: [Isolated congenital diverticulum of the left ventricle disclosed by ventricular tachycardia in a 72-year-old woman].
abstract: A 72-year-old woman presented with poorly tolerated ventricular tachycardia reduced by intravenous amiodarone. The possibility of an ischaemic aetiology led us to perform coronary angiography. The coronary arteries were pathological. Left ventricular angiography revealed limited anterior hypokinesia and a large contractile apical pouch appended to the left ventricle by a long narrow neck. Despite the appearance suggestive of congenital left ventricular diverticulum (contractility, narrow neck) and because of the coexistence of ischaemic heart disease, we preferred to confirm the muscular nature of the diverticulum by myocardial thallium scintigraphy, which showed reversible decreased uptake in the anterior zone related to coronary artery disease, and confirmed the muscular nature of the diverticulum which showed normal thallium uptake. MRI clearly visualized the ventricular ectasia attached by a narrow neck to the rest the left ventricle. This long narrow neck indicated that this muscular diverticulum constituted a congenital diverticulum. The contribution of ultrasonography was limited by a poorly defined point during the examination. This congenital diverticulum, discover during adulthood, and previously asymptomatic, is a rare lesion, in the light of a review of the literature.
