RESUMEN
El procedimiento de Cox-maze ha sido diseñado para
eliminar cualquier tipo de fibrilación auricular ó flutter.
Es un procedimiento quirúrgico que está compuesto por
una serie de incisiones quirúrgicas ó lineas de quemadura
estratégicamente colocadas para eliminar ó interrumpir
cualquier macro-circuito de reentrada ó rotor
en ambas aurículas. Esto es posible gracias a un patrón
de lesiones biauricular completo. Este es un
non-focal
approach, razón por la cual es altamente efectivo eliminando
la fibrilación auricular en una sola etapa. Cada
una de estas lesiones del Cox-maze son críticas, teniendo
siempre que estar ancladas a uno de los anillos valvulares,
o a otra lesión en sí misma. También tienen que
cruzar en su totalidad la extensión de tejido miocárdico
auricular antes de terminar en alguno de sus extremos.
La más crítica de todas ellas, debido a la complejidad de
la anatomía que en ella se encuentra, es la lesión del istmo
mitral. El fallo en su correcta ejecución determina
hasta 15-20% de fracaso en el procedimiento de Coxmaze.
La cryoablación doblemente aplicada en esta zona
es la única fuente de energía alternativa capaz de lograr
una tasa de éxito cercana al 90%. Analizamos el detalle
en este manuscrito.
