Long-Term Follow-Up of Cardiac Rhythm in 320 Patients After the Cox-Maze III Procedure for Atrial Fibrillation

Abstract

In a single-moment electrocardiogram evaluation 9 years after the cut-and-sew CM-III, 82% of patients were in sinus rhythm or other regular supraventricular rhythm. These findings support a long-lasting positive effect of the CM-III procedure, which is relevant when evaluating current nonpharmacologic therapies for AF.

Surgical management of atrial fibrillation at the time of septal myectomy

“…For concomitant AF ablative surgery, outcomes with the classic Maze III lesion pattern (either cut-and-sew or cryoablation) can be expected to be superior to those achieved with "modifications" of the original lesion set (15,16). When using the original lesion pattern, the long-term success rate did not vary on the basis of the classic predictors of failure (15,17).…”

“…Early success with concomitant AF ablation associated with non-HCM aortic valve disease and mitral valve disease is above 75% in the absence of the classical risk factors for poor prognosis (age beyond 75, LA Diameter over 50 mm, duration of AF more than 5 years and non-paroxysmal AF) (13,14). For concomitant AF ablative surgery, outcomes with the classic Maze III lesion pattern (either cut-and-sew or cryoablation) can be expected to be superior to those achieved with "modifications" of the original lesion set (15,16). When using the original lesion pattern, the long-term success rate did not vary on the basis of the classic predictors of failure (15,17).…”

Thoracoscopic Pulmonary Vein and Left Atrial Posterior Wall Isolation Combined with Left Atrial Appendage Resection in Patients with Long-Standing Persistent Atrial Fibrillation

“…It became the gold standard in surgical treatment of AF. However, due to technical complexity (median sternotomy and the use of a cardiopulmonary bypass) and assumed increase in morbidity, CM III is not widely used nowadays [16,17] .…”

Examination of Electrophysiological Parameters of the Atriums in Patients With Long-Term Persistent Form of Atrial Fibrillation and Valvular Heart Disease

“…В исследовании A. Albage и соавт. [26], в котором перед проведением операции «Лабиринт III» 27 пациентам выполняли исследование проводящей системы сердца, у 15 % пациентов было выявлено нарушение проведения по правому предсердию.…”
