Abstract

Doppler echocardiography was performed in 80 consecutive patients (22 men, 58 women), aged 38 ± 16 years, who had mitral valve prolapse diagnosed by two-dimensional echocardiography. Of the 80 patients, 16 (20%) were asymptomatic and 11 (14%) had a normal physical examination (no click or murmur). The M-mode echo, cardiogram was negative for mitral valve prolapse in 11 patients (14%) and equivocal or nondiagnostic in 19 patients (24%). Mitral regurgitation was evaluated using pulsed mode Doppler echocardiography and was quantified by the mapping technique as minimal or mild when a holosystolic regurgitant jet was recorded just below the mitral valve into the left atrium, and as moderate or severe when the jet was detected at the mid- or distal left atrium. Mitral regurgitation was found in 55 (69%) of the 80 patients and it was minimal or mild in 47 patients (59%) and moderate or severe in 8 (10%). In 20 (36%) of the 55 patients with Mitral regurgitation by Doppler technique, a systolic murmur was not detected and each of the 20 had only mild mitral regurgitation. Left atrial and left ventricular size were significantly smaller in patients with mild or no regurgitation as compared with the eight patients with moderate or severe regurgitation. These eight patients were all men (six over 50 years of age) who usually presented with dyspnea and a holosystolic murmur; the Mitral valve prolapse was holosystolic by M-mode and involved both leaflets by twodimensional echocardiography. In conclusion: 1) Mitral regurgitation as assessed by Doppler echocardiography was common in patients with mitral valve prolapse, but was usually mild and not always associated with an audible murmur. 2) Significant Mitral regurgitation was rare (10%) and usually occurred in men with Mitral valve prolapse who were more than 50 years old.
