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.
