Abstract
Las asistencias ventriculares son dispositivos esenciales en el manejo de pacientes con insuficiencia cardíaca avanzada. Estas herramientas actúan como puente hacia diversas opciones terapéuticas, entre las que se incluyen el trasplante cardíaco, la terapia de destino o la estabilización del paciente mientras se toma una decisión definitiva. Existen dos tipos principales de dispositivos de asistencia ventricular, clasificados según el flujo que generan: flujo continuo y flujo pulsátil. Aunque los dispositivos de flujo continuo presentan ventajas técnicas, los sistemas de flujo pulsátil ofrecen una mayor similitud con las condiciones fisiológicas normales. Esta dualidad genera una controversia respecto a qué tipo de flujo resulta más beneficioso para los pacientes. Un problema importante en los pacientes con asistencia ventricular es la aparición de complicaciones asociadas al dispositivo, siendo las complicaciones cerebrovasculares las más frecuentes y limitantes. Estas derivan principalmente de la necesidad de anticoagulación crónica y de las alteraciones que los dispositivos inducen en el sistema circulatorio normal...
