Cox maze operation without cryoablation for the treatment of chronic atrial fibrillation

Randomized study of surgical isolation of the pulmonary veins for correction of permanent atrial fibrillation associated with mitral valve disease

“…16 This technique was modified by others, and in some reports cryoablation was not used. 17,18 More recently, Fieguth, Wahlers, and Borst 19 and Haissaguerre and colleagues 20 demonstrated that pulmonary veins, inside the left atrium, are the main focus of triggering and maintaining paroxysmal AF. In this situation and on the…”

Procedimiento de Cox-maze III para la fibrilación auricular. Un estudio preliminar

“…Finalmente, respecto a la no utilización de criolesión en los puntos clásicos descritos por Cox, como son el istmo mitral y el istmo cavo-tricuspídeo, existen reportes previos acerca de la no utilización de crioablación en el procedimiento de Cox-maze III 22 . La premisa es que se tiene que dividir quirúrgicamente todo el espesor del tejido muscular hasta llegar a la grasa epicárdica, la cual no es conductora de electricidad.…”

Isolamento das veias pulmonares em pacientes com fibrilação atrial permanente secundária a valvopatia mitral

“…The association of the Cox technique with mitral valve disease correction became attractive due to the high prevalence of this disease, and it has proved to be effective 4,5,25,26 . However, the complexity of the incisions necessary for performing the Maze procedure and the need for additional instrumentation (cryoablation) hindered its diffusion, leading the researchers to develop simplified alternative techniques 14,15,27 .…”
