Abstract
A case of an 81-year-old woman with a left ventricular diverticulum who underwent myocar dial 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 proper ties 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.
