ABSTRACT

Background. Restrictive cardiomyopathy is an uncommon disease in the Western World, where echocardiogram represents an excellent diagnostic tool in these patients. Objective. To present our experience in the echocardiographic evaluation of patients with restrictive cardiomyopathy. Material and methods. 8 patients were included, all of them were evaluated with at least 2 echocardiographic criteria for restrictive cardiomyopathy. With transthoracic echocardiography we evaluated the anatomical characteristics and with pulsated Doppler we evaluated the ventricular filling patterns. Later on we corroborate the results with a transesophageal study. Results. 8 patients were recruited, from those 6 (75%) presented symmetrical restrictive cardiomyopathy, and two with asymmetric restrictive cardiomyopathy (25%). These 2 also had intraventricular thrombus (25%). The average result of the E/A relation was of 4.16±1.09, the average time of deceleration of the E wave was of 76.75±15.69, the calculated mode was 70 and a median of 75; the average of the maximum speed of the E wave was 1.57±0.21, the maximum speed average of the A wave was 0.38±0.08, and the average of the TRIVI was 70.5±3.42, with a mode of 70 and a median of 70. The findings in the transesophageal study match in 95% with the data of transthoracic echocardiography. Discussion. Echocardiography continues to be a useful tool for the diagnosis of this disease. The anatomical characteristics and ventricular filling pattern constitute the initial data to establish the diagnosis by image. Conclusions. echocardiography was a useful toll for the diagnosis of restrictive cardiomyopathy.
