Predictors of Long-Term Outcome after Percutaneous Balloon Mitral Valvuloplasty

Abstract

Balloon mitral valvuloplasty as a treatment for selected patients with mitral stenosis has good long-term results. The long-term outcome after this procedure can be predicted on the basis of patients' base-line characteristics.

Resultados a largo plazo de la valvuloplastía mitral con balón

“…Este modelo ha sido replicado en otras publicaciones 7,12,15,16 y se encuentra ampliamente reconocido como un buen indicador del resultado global de la VMB. Sin embargo, puede tender a sobreestimar la tasa de eventos.…”

“…Su efectividad, en cuanto a la magnitud de dilatación valvular, se correlaciona con el grado de alteración anatómica de la válvula 3 , y los resultados inmediatos son similares a los obtenidos con la comisurotomía quirúrgica cerrada 4 o abierta 5 , pero con menor morbilidad 6 . Del mismo modo, a mediano plazo existe evidencia de sus resultados favorables, con baja mortalidad y más de la mitad de los pacientes libres de eventos 7 . Sin embargo, disponemos de menos información sobre sus resultados clínicos alejados y de los factores que pueden determinarlos.…”

Acute and long-term follow-up results of percutaneous mitral balloon valvuloplasty: a single-center study

“…Predictors of immediate procedural results have been analyzed in prior series and indicate that determinants of success are multifactorial (1)(2)(3)(4)(5)(6)(10)(11)(12)(13). Early risk scores were comprised of semi quantitative assessment of leaflet thickening, subvalvular change, leaflet mobility, and valve calcification, and thus initial procedural experience was limited to patients with pliable, noncalcified mitral valves (14).…”

“…Percutaneous mitral balloon valvuloplasty (PMBV) has been developed as an alternative modality to surgical closed commissurotomy for mitral stenosis (MS) (1), and excellent hemodynamic improvement with favorable outcome has been reported by many investigators (2)(3)(4)(5)(6)(7)(8)(9)(10)(11). Although numerous studies have documented favorable immediate and intermediate-term results, long-term echocardiographic follow-up studies are rare (1)(2)(3)(4)(5)(6)(10)(11)(12)(13).…”
