Percutaneous transvenous mitral commissurotomy (PTMC) for severe, symptomatic mitral stenosis was successfully performed in 47 of 50 patients with pliable, non-calcified valves. The procedure resulted in immediate hemodynamic and sustained clinical improvements in all patients. Repeat cardiac catheterization was performed in 22 patients at a mean follow-up period of 15 months (range 12 to 29). The patients were similar to the other 25 patients in regard to gender, age, clinical and hemodynamic characteristics. There were 4 males and 18 females with a mean age of 37 years (range 20 to 61). Immediately after PTMC, there were significant increases in the mitral valve area (1.0 +/- 0.2 to 2.4 +/- .9cm2, p less than 0.001) and cardiac index (3.1 +/- 0.7 to 3.3 +/- 0.7 l/min/m2, p less than 0.05) and significant (p less than 0.001) decreases in the left atrial pressure (25.7 +/- 6.4 to 13.2 +/- 3.9 mmHg), the mitral valve gradient (15.7 +/- 5.7 to 3.9 +/- 1.4 mmHg), mean pulmonary arterial pressure (41.5 +/- 10.7 to 29.2 +/- 10.9 mmHg) and the pulmonary vascular resistance (4.2 +/ 3.4 to 3.5 +/- 2.9 Wood unit). At follow-up study, the mitral valve area (2.2 +/- 0.7 cm2) and the left atrial pressure (12.6 +/- 3.7 mmHg) remained unchanged. There were further decreases in the mean pulmonary arterial pressure (22.4 +/- 5.9 mmHg, p less than 0.05) and the pulmonary vascular resistance (2.0 +/- 1.5 Wood unit, p less than 0.05). There were significant (p less than 0.05) increases in the mitral valve gradient (6.6 +/- 2.5 mmHg) and the cardiac output (3.6 +/- 0.7 l/min/m2).(ABSTRACT TRUNCATED AT 250 WORDS)
