[Left ventricular outflow obstruction due to accessory mitral tissue].

An asymptomatic 31-year-old woman was studied because she presented a systolic ejection cardiac murmur. The echocardiogram showed a mobile, sac-like mass attached to the ventricular surface of the anterior mitral leaflet and its chordae tendineae and papillary muscle. This structure moved to the left ventricular outflow tract during every systole occupying the subaortic area. Conventional and color-coded Doppler examination revealed left ventricular outflow obstruction caused by the accessory mitral valve tissue that produced a high-velocity turbulent flow pattern in the subaortic area where the sac-like structure approximated to the outflow tract walls.

[Left ventricular pseudoaneurysm. The dynamics and flow patterns analyzed by Doppler echocardiography].

A patient with antecedents of ischemic cardiopathy is presented. Echocardiographic exploration revealed the presence of an accessory cavity in connection with the left ventricle behind the basal segment of the posterior left ventricular wall, the characteristics of which were compatible with a ventricular pseudoaneurysm. The Doppler study (both conventional and color coded) allowed us to determine the multiphasic characteristics of the flow between both cavities, and its relation with the variations of volume of the same, as well as with the transmitral and aortic flows. The filling of the pseudoaneurysm was observed to begin before initiation of the ejection through the aorta. Initiation of emptying towards the left ventricular cavity took place in the late systole, and there was a new flow inversion towards the pseudoaneurysm in the early diastole coinciding with the rapid ventricular filling, and therefore before producing the atrial contraction.
