[Mitral percutaneous valvuloplasty with Inoue balloon. Long-term results at the National Medical Center " 20 of November" ISSSTE Mexico].

UNLABELLED: Balloon mitral valvuloplasty has, over the last 15 years, become an established interventional procedure for patients with pliable non-calcified mitral stenosis. In this article we describe the long-term outcome of 100 patients from our hospital (National Medical Center "20 de Noviembre" ISSSTE, Mexico City), who were treated with this procedure. Average follow-up was 38.72 +/- 22.4 months. The procedure was successful in 83.3% of the patients. After the procedure, the average valvular area changed from 0.95 +/- 0.16 to 1.62 +/- 0.24 cm2 (P < 0.001) and, at the end of the follow-up time, it was 1.57 +/- 0.29. The trans-valvular mean gradient changed from 8.80 +/- 3.67 mm Hg to 4.74 +/- 1.90 mmHg (P < or = 0.001). Complications occurred in 7.0% of the patients, the most important one being acute mitral insufficiency due to valvular rupture. No deaths occurred. CONCLUSIONS: Balloon valvuloplasty is an effective method in patients with Wilkins score of 8 or less, with minimal risk of complications, and long lasting results. At the end of the follow-up time, patients were in NYAH functional class I.

[Ambulatory pacemaker surgery].

The chronic cardiac stimulation is know since 1958, pacemaker implant was considered a difficult procedure that was performed through cardiovascular surgery and the patient required several in hospital days. On the grounds of new surgical techniques and development of new materials for pacemakers, as well as the rise of Ambulatory Surgery and its application in pacemaker implants, the hospital stay and consequently, costs have decreased significantly. In 1986, Zegelman reported 583 patients subjected to ambulatory pacemaker surgery without mortality. The purpose of this report it to evaluate the efficacy and safety of ambulatory pacemaker surgery. One hundred seventy seven patients from an ambulatory program and 95 from a traditional program were included. Hospitalization time was 15.7 +/- 15.1 hours in the first group and 238 +/- 188 hours for the second, prevalence of complications was 2.2% in the 272 patients. Complications for both groups were similar and were solved, without mortality. We conclude that the ambulatory pacemaker surgery is effective and safe for patients and is cheaper for hospitals. The success of this program depends on the number of implants in each hospital and the operator's experience.
