| Popis: | We studied the mechanism of severe mitral regurgitation (MR) secondary to acute myocardial infarction and the prognosis of patients who underwent surgical mitral repair. The subjects were nine patients (2 men and 7 women) ranging in age from 58 to 78 years (mean, 73), who underwent immediately surgical treatment for acute MR. The site of infarction was inferior in eight patients and anterior in one. Severe congestive heart failure, shock or hypotension existed in all patients. The mechanism of MR was accurately diagnosed with two-dimensional and Doppler echocardiography in five patients with leaflet prolapse, and ruptured papillary muscle in four patients with restricted motion of the posterior leaflet and central regurgitation. Mitral valvuloplasty was attempted in six patients (two with ruptured papillary muscle and four with papillary muscle dysfunction. Three patients underwent mitral valve replacement on the 4.2 (mean) hospital day. Death occurred in one patient who had already developed severe multiple organ failure by admission. One patient with mitral valve replacement underwent reoperation for late thrombosis of the artificial valve. No cardiac events occurred over the long term in patients with mitral valvuloplasty. We concluded that mitral valvuloplasty, when technically feasible, is the procedure of choice for acute ischemic MR because valve-related events are less than valve replacement. |
