Abstract
La insuficiencia cardiaca congestiva es una enfermedad con una prevalencia que aumenta cada año, estimándose que afecta a unos 23 millones de personas en todo el mundo. A pesar de los avances terapéuticos de los últimos años, una vez alcanzada su fase terminal el pronóstico continúa siendo muy sombrío, con una mortalidad que alcanza el 50% al año. En esta fase de la enfermedad, el trasplante cardiaco es el tratamiento de elección, siendo la escasez de donantes su gran limitación. En un intento de salvar esta limitación surgen los dispositivos de asistencia mecánica circulatoria, mostrándose como un complemento o, incluso, como una alternativa válida al trasplante cardiaco. La evolución de estos dispositivos a lo largo de los últimos 60 años ha sido sobresaliente. Desde los primeros dispositivos paracorpóreos, de gran tamaño y de flujo pulsátil se ha pasado a dispositivos intracorpóreos, de pequeño tamaño y de flujo continuo, con una gran mejoría en términos de biocompatibilidad. De este modo, las complicaciones se han reducido drásticamente, lo que se ha traducido en un aumento tanto de la esperanza como de la calidad de vida de estos pacientes...
Congestive heart failure is a disease with a prevalence that increases every year, affecting about 23 million people worldwide. Despite the therapeutic advances of recent years, once the terminal phase has been reached, the prognosis continues to be poor, with mortality reaching 50% in the first year. In this phase of the disease, heart transplant is the treatment of choice, with the shortage of donors being its great limitation. In an attempt to overcome this limitation, mechanical circulatory support devices emerge, showing themselves as a complement or even a valid alternative to heart transplantation.The evolution of these devices over the last 60 years has been outstanding. From the first paracorporeal devices, large in size and with pulsatile flow, we have moved on to smaller intracorporeal devices with continuous flow, with a great improvement in terms of biocompatibility. In this way, complications have been drastically reduced, which has translated into an increase in both survival and quality of life of these patients...
