| Popis: | Percutaneous mitral valvuloplasty (PMV) was performed in 57 patients with mitral stenosis. Twenty-three women and 34 men (mean age 28 +/- 10 mean +/- SD) were included in the study. A single-balloon (trefoil or bifoil) technique was used in 49 patients and a double-balloon (trefoil + monofoil) technique in eight. After a 3-month follow-up period, right- and left-sided cardiac catheterization was repeated. In the single-balloon group there was improvement in the mitral valve gradient (16.10 +/- 5.99 to 4.41 +/- 2.03 mm Hg), mean left atrial pressure (22.65 +/- 6.13 to 9.76 +/- 3.01 mm Hg), and mitral valve area (0.89 +/- 0.22 to 1.95 +/- 0.46 cm2/m2). Mean pulmonary artery pressure and mean pulmonary wedge pressure decreased to 19.33 +/- 4.19 mm Hg and 10.73 +/- 2.60 mm Hg from 32.94 +/- 7.90 mm Hg and 21.49 +/- 5.98 mm Hg. Cardiac output increased to 6.86 +/- 0.56 L/min from 5.57 +/- 0.66. All improvements were statistically significant (p less than 0.001). In the double-balloon study group, mitral valve gradient (23.75 +/- 2.77 to 4.50 +/- 1.94 mm Hg), mean left atrial pressure (31.63 +/- 3.57 to 9.50 +/- 1.94 mm Hg), mean pulmonary artery pressure (44.00 +/- 6.36 to 18.88 +/- 7.10), and mean pulmonary wedge pressure (29.25 +/- 3.73 to 10.25 +/- 1.85 mm Hg) all improved significantly (p less than 0.001). Mitral valve area and cardiac output increased from 0.89 +/- 0.15 to 2.44 +/- 0.44 cm2/m2 (p less than 0.001) and from 5.46 +/- 0.76 to 7.15 +/- 0.52 L/min (p less than 0.002), respectively.(ABSTRACT TRUNCATED AT 250 WORDS) |
