RESUMEN

El propósito del presente trabajo consiste en demostrar la elevada incidencia de mortalidad en los enfermos que cursan con valvulopatía aórtica del tipo de la estenosis, en fases avanzadas del padecimiento, que se manifiestan clínicamente por datos de disfunción ventricular con Insuficiencia Cardiaca. Esta disfunción ventricular se manifiesta por la presencia de gradientes transvalvulares aórticos bajos, y deberá diferenciarse entre disfunción ventricular reversible, cuyo tratamiento será el reemplazo valvular aórtico, y la disfunción ventricular irreversible, en los cuales el tratamiento quirúrgico no aportará beneficio.
