Comparison of the inoue and single balloon techniques during long term percutaneous balloon mitral valvoplasty follow-up. Analysis of risk factors for death and major events.

Objective: To analyze the long term evolution of patients undergoing percutaneous balloon mitral valvoplasty comparing the Inoue and Balt single balloon methods, and to identify predictors of death and major events (death, repeat balloon mitral valvoplasty or mitral valve surgery).

Methods: The follow-up for the single and Inoue balloon groups were 54 +/- 31 (1 to 126) months and 34 +/- 26 (2 to 105) months, respectively (p < 0.0001).

[Gender influence on the immediate and medium-term progression after primary percutaneous coronary intervention and analysis of independent risk factors for death or events].

Objective: Determine gender-related differences and risk factors for death and events, both in-hospital and at six-month evolution, of patients admitted within the first twelve hours of ST-segment elevation acute myocardial infarction and who underwent primary percutaneous coronary intervention.

Methods: Between July 1998 and December 2000, 199 consecutive patients were enrolled in the study, with elevation myocardial infarction and without cardiogenic shock, outcome, in-hospital and six-month progression were studied.

Results: Clinical characteristics were similar in both groups, except that women were older than men (67.

[Percutaneous mitral balloon valvotomy. Long-term outcome and assessment of risk factors for death and major events].

Objective: To identify the factors that predict death and combined events, (death, new mitral balloon valvotomy, or mitral valve surgery) in long-term follow-up of patients undergoing percutaneous mitral balloon valvotomy.

Methods: Follow-up was 49.0+/-31.
