Abstract

Among the causes of left ventricular outflow tract obstruction, accessory mitral valve tissue is one of the last described and least studied. At present echocardiography permits a complete exploration of the atrioventricular valves as well as left ventricular outflow tract. In this study we evaluate the information obtained in four patients with two-dimensional echocardiography and color-coded Doppler by both transthoracic and transesophageal approaches. The information was compared with catheterization results. In none of the three cases in which hemodynamic study was performed, diagnostic angiographic images of the anomaly were obtained. Transesophageal echocardiography gave additional information about the mitral valve and subvalvular apparatus, the site of accessory tissue implantation and associated lesions.
