[Long-term results of percutaneous mitral valvuloplasty in patients over 50 years old].
Advanced age has been identified as a predictor factor for complications and poor outcome at Percutaneous Mitral Valvulotomy (PMV) with balloon, nevertheless this has been associated to the inadequate valvular anatomy, whereby the contribution of each factor needs to be determinate.


OBJECTIVE
Describe the immediate and final outcome of PMV with Inoue balloon in patients over 50 years old and associate complications with age and Wilkins score.


METHODS
A retrospective and analytic study was performed with a data base of 430 patients. We included all the patients proceeding from the Centro Medico Nacional Siglo XXI Cardiology Hospital. From January 1996 to December 2005.


RESULTS
We selected 137 patients with rheumatic mitral stenosis. We found a Mitral Valvular Area (MVA) before the PMV proceeding of 1.01 cm2 +/- 0.18 and 1.99 cm2 +/- 0.30 post PMV (P < 0.001), with pre procedure transmitral gradient of 14.3 +/- 3.18 mm Hg and of 4.3 +/- 2.6 mm Hg post (P < 0.001). In 128 (93%) the immediate proceeding was considered successful. The Wilkins score was 8.41 +/- 1.31. The observed complications were present in 19 (13.8%), stroke in 3 (2.2%), tamponade in 3 (2.2%), conduction disorder in 5 (3.7%), severe mitral insufficiency in 7 (5.1%), residual interatrial communication in 1 (0.7%). A clinical and echocardiographic follow-up was performed in 113 (83%) MVA was > 1.5 cm2 in 113 at 70 [IBM1] months average, 1.1 to 1.49 cm2 in 14 (10.2%) and < 1 cm2 in 9 (7%).


CONCLUSIONS
PMV with Inoue balloon in patients over 50 years old is a procedure with an immediate high successful index and of acceptable risk. We found a restenosis index of 27 (19%) after long follow-up 70 months average.
