162: Percutaneous mitral balloon commisurotomy in patients with restenosis after surgical commisurotomy: A comparative study - 01/07/14
Résumé |
Methods |
We performed percutaneous mitral balloon commisurotomy (PMC) in 361 patients to compare the effectiveness of PMC between patients with mitral restenosis after surgical commissurotomy (group 1) and patients with unoperated mitral stenosis (group 2). Thirty-nine had undergone closed or open mitral commissurotomy 8.4 years before.
Results |
There were no significant differences in clinical profiles between the two groups. The mitral valve area was increased from 1.1 0.31 to 1.94 0.58cm2 in group 1 and 0.94 0.3 to 2 0.7cm2 in group 2 (p>0.05). The mitral gradient was decreased from 14.6 5.9 to 6 2.6 mm hg in group 1 and 18 7.0 to 7 5.3 mm hg in group 2 (p>0.05). The increment of mitral regurgitation and significant left to right shunt after PMC were not significantly different (8.9% versus 13.7%, 4.2% versus 8.4% respectively). Optimal results were attained in 81% of the patients in group 1 and in 88.3% of the patients in group 2 (p>0.05).
Conclusion |
These results suggest PMC in mitral restenosis after surgical commissurotomy may be safe in selected patients and may be equally effective as in unoperated mitral stenosis.
