Diverticulum of the left ventricle associated with subvalvar aortic stenosis

Multiple left ventricular diverticuli in an asymptomatic adult: Case report and review of the literature

Left ventricular (LV) diverticulum is a rare congenital abnormality for which the etiology, management, and natural history are very poorly understood. Although most often observed as a single diverticulum, we report a case of multiple LV diverticuli in an asymptomatic adult referred for coronary evaluation due to an abnormal electrocardiogram. LV diverticuli are often associated with other congenital malformations, but can also be found in isolation. Cardiac magnetic resonance imaging provides enhanced ability to determine size, location, and morphological characteristics, which may improve lesion assessment and management. A review of the condition and reported complications is discussed.

Contrast harmonic power Doppler imaging of congenital ventricular diverticulum--a case report

A case of an 81-year-old woman with a left ventricular diverticulum who underwent myocardial contrast echocardiography is reported. After administration of the contrast agent, a pulsed Doppler flow measurement clearly revealed the biphasic waveform of the ejection flow in the pre-systolic and systolic phase at the ostium of the diverticular cavity. A harmonic power Doppler image showed that part of the diverticulum wall had similar acoustic properties to the ventricular septal wall. Intracardiac blood flow and myocardial perfusion could be clearly evaluated and a ventricular diverticulum was correctly diagnosed using contrast echocardiography.

Left ventricular septal aneurysm in association with bicuspid aortic valve--a case report

Diverticula of the left ventricle are rare cardiac anomalies. Most cases arise from the apex of the left ventricle and are usually found in children. Only a few cases have been documented in adults. The authors report a case of a 38-year-old woman who presented with dyspnea and chest pain. She was found to have a septal left ventricular diverticulum associated with bicuspid aortic valve, aortic stenosis, and aortic regurgitation. The aortic valve was replaced with the resection of the diverticulum. Pathologic examination confirmed the diagnosis of fibrous diverticulum.
