[The immediate and midterm results of percutaneous mitral valvuloplasty in subjects over 60].
We have analyzed the immediate and mid-term (1 and 2 years) results of percutaneous mitral valvuloplasty (PMV) by Inoue's catheter in 97 patients < 60 years (Group A) compared with 34 patients > 60 years (Group B). In 61% Group A the patients were in NYHA functional class II, 36% in III, and 3% in I; in Group B, 56% of the patients were in NYHA functional class III, 38% in II, and 6% in IV. Mean mitral valve area was 1.1 cm2 before dilatation in both groups, and a significant (p < 0.0001) increase was obtained in both Group A (0.9 +/- 0.3 cm2) and Group B (0.8 +/- 0.3 cm2). No significant differences were observed between the two groups. Mean transvalvular gradient decreased significantly (p < 0.0001) from 13.6 +/- 5.7 to 7.2 +/- 3.1 mmHg in Group A, and from 9.9 +/- 4 to 6.5 +/- 2.3 mmHg in Group B (A vs B: p < 0.02). Optimal result was obtained in 94% and 88% of Group A and Group B patients, respectively. Suboptimal result was obtained in 2% and 6% of Group A and Group B patients, respectively. These differences were not significant. Failure of PMV occurred in 4% and 6%, respectively. At 1-year follow-up Group A 7 patients and 5 Group B patients showed restenosis; at 2-year follow-up one more restenosis was present in Group A (A vs B at 1 and 2 years: NS). We conclude that PMV is a safe and effective technique in young patients and in patients > 60 years.
