Percutaneous mitral valvuloplasty. Results and follow-up

pp 409-414

Abstract

Since november 1988 to may 1991 we performed 19 procedures of mitral valvuloplasty for mitral stenosis. All the patients were female and mean age was 44.4 years. Twelve patients were in class I-ll and seven in class III-IV. Five patients had atrial fibrillation, and two previous open heart commissurotomy. One patient was pregnat (sixth month). One patient with combined (mitral and tricuspid) stenosis was submitted to double valvuloplasty. The technique was conventional single balloon in four patients, double balloon in one and Inoue balloon in twelve patients. The primary success was 73.7 % (14/19). The failures were due to: failure in the transeptal puncture in two patients, failure in the cross the mitral valve in one patient. One patient develop severe mitral regurgitation. One patient died because a stroke. The left atrial mean pressure decrease from 21.9 ± 2.25 to 9.3 ± 1.63 (P < 0.(01). The mean gradient decrease from 13.6 ± 1.83 to 3.9 ± 10.21. The mitral valve area increase from 1.31 ± 0,4 cm2 to 2.47 ± 0,7 cm2 (P<O.OOI) and the cardiac output increase from 4.69 ± 0,93 to 5,71 ± 1.15 (P < 0.001). The mean follow up was 9.67 month (1-24). The 85.7 % (12) of patients were free of symptoms. Two patients both done with single balloon technique had recurrence at 12 and 24 month follow up respectively.
