Atrial fibrillation (AF) is the most common cardiac arrhythmia. The incidence of AF increases with age and is associated with increased stroke, heart failure and mortality. Persistent and long standing persistent AF is difficult to treat and often refractory to medical therapy and catheter ablation. Areas covered: This article reviews the historical development of the surgical Cox-MAZE procedure and current hybrid and minimally invasive surgical approaches for the treatment of persistent and long standing persistent AF...

Background: The radiofrequency (RF) maze procedure can effectively restore sinus rhythm in most patients with persistent atrial fibrillation (AF) and mitral disease. However, long-term results and predictors for late AF recurrence are still under investigation. Methods: From December 1995 to November 2011, 207 consecutive patients with persistent AF and mitral disease underwent RF maze procedure and concomitant mitral surgery. The mean age was 54±12.4 year-old...

OBJECTIVES: Oral anticoagulants have inherent risks. In the absence of clear evidence, anticoagulant use after surgical ablation for atrial fibrillation remains variable. This study examined patient outcomes with and without oral anticoagulants after successful surgical ablation. METHODS: From October 2011 to April 2016, 239 consecutive patients underwent biatrial Cox Maze IV operations for persistent atrial fibrillation. All patients received endocardial left atrial appendage obliteration...

Introduction: Atrial fibrillation is the most common cardiac arrhythmia in the United States. It has been associated with a reduction in patient quality of life and more serious complications such as stroke and heart failure. The aim of this study was to compare the efficacy of commonly performed invasive procedures in keeping patients in normal sinus rhythm. Methods and Results: A retrospective chart review was performed on all patients who underwent primary radiofrequency catheter ablation, the complete Cox-maze, or the hybrid maze at OSF Saint Anthony Medical Center between January 2010 and December 2013 (n=140)...

BACKGROUND: Rhythm control is challenging in patients with extended atrial fibrillation (AF) duration and persistent/long-standing persistent AF. Among surgical approaches to treat AF, the Cox maze procedure performed using alternative energy sources remains superior to other beating heart techniques. We examined permanence of safety and success for the on-pump, minimally invasive, stand-alone Cox maze procedure 5 years after surgery. METHODS AND RESULTS: Stand-alone, right 5 cm minithoracotomy, Cox maze III/IV procedure for nonparoxysmal AF was conducted in 133 patients (mean follow-up=65±34 months)...

OBJECTIVE: Atrial fibrillation (AF) is associated with an increased mortality risk. The Cox-maze IV procedure (CM4) performed concomitantly with other cardiac procedures has been shown to be effective for restoring sinus rhythm. However, few data have been published on the late survival of patients undergoing a concomitant CM4. METHODS: Patients undergoing cardiac surgery were retrospectively reviewed from 2001 to 2016 (n = 10,859). Patients were stratified into 3 groups: patients with a history of AF receiving a concomitant CM4 (CM4; n = 438), patients with a history of AF unaddressed during surgery (Untreated AF; n = 1510), and patients without AF history (No AF; n = 8911)...

OBJECTIVE: The appearance of atrial fibrillation is associated with significant clinical deterioration in patients with obstructive hypertrophic cardiomyopathy; therefore, maintenance of sinus rhythm is desirable. Guidelines and most articles have reported the results of catheter ablation and pharmacologic atrial fibrillation treatment; nevertheless, data regarding concomitant procedures during septal myectomy are limited. The aim of this study was to assess the outcomes of concomitant atrial fibrillation treatment in patients with obstructive hypertrophic cardiomyopathy...

Atrial fibrillation (AF) may appear during the natural clinical course of hypertrophic cardiomyopathy (HCM). It is regarded as a complication of HCM and is a marker of advanced disease. AF is more likely to occur in untreated, obstructive HCM. Unfortunately, this represents a turning point that puts patients at increased risk of further disability, stroke and death. The presence of obstruction is an indication to proceed with septal myectomy to improve or resolve symptoms by ameliorating diastolic dysfunction...

BACKGROUND: Atrioventricular nodal reentry tachycardia (AVNRT) is common in adults and often involves reentry through ≥2 atrioventricular nodal-atrial connections. Although AVNRT can be a trigger for atrial fibrillation (AF), we have observed new-onset AVNRT after AF ablation procedures. OBJECTIVE: The purpose of this study was to determine whether ablation involving the septum or proximal coronary sinus (CS) during AF ablation may create a substrate favorable for AVNRT...

Atrial fibrillation (AF) is the most common arrhythmia in humans and is known to be associated with an increased risk of stroke, dementia, heart failure and mortality. Non-pharmacological therapy with ablation using either surgical or percutaneous techniques is recommended in drug refractory AF. Early attempts to devise procedures to ablate AF and restore sinus rhythm culminated with the Cox-Maze procedure, the first truly successful procedure. Since then, ablation surgery has been conducted predominately as a concomitant procedure...

BACKGROUND: In elderly patients who have atrial fibrillation (AF), surgical ablation of the arrhythmia during cardiac surgery may be challenging. Despite the reported advantages of ablating AF with the Cox maze procedure (CMP), the addition of the CMP may complicate other cardiac operations. We evaluated the effect of the CMP in elderly patients concurrent with other cardiac operations. METHODS: From October 2007 to December 2015, we enrolled 27 patients aged >70 years who had AF and who underwent the CMP concurrently with other cardiac operations...

BACKGROUND: The absence of atrial contraction (AC) after the maze procedure has been reported to cause subsequent annular dilatation and to increase the risk of embolic stroke. We hypothesized that the lack of AC could increase the risk of permanent pacemaker (PPM) implantation in patients undergoing the maze procedure. METHODS: In 376 consecutive patients who had undergone a cryo-maze procedure and combined valve operation, recovery of AC was assessed at baseline and at immediate (≤2 weeks), early (≤1 year, 4...

OBJECTIVE: To determine whether the etiology of mitral valve disease (MVD), due to either rheumatic or degenerative pathology, influences long-term outcomes after the Cox-Maze IV procedure (CMPIV). METHODS: Between February 2001 and July 2015, 245 patients received a CMIV and concomitant mitral valve procedure. Patients were separated into 2 cohorts based on their etiology of MVD, degenerative (n = 153) and rheumatic (n = 92). Patients were followed prospectively (mean follow-up: 41 ± 37 months) for recurrent atrial tachyarrhythmias (ATAs)...

BACKGROUND: The Cox maze (CM) procedure is routinely performed using surgical ablation technology. Reports are scarce on long-term outcomes of CM, especially for a large series of patients. This study examined the potential impact of surgical ablation energy source on safety and long-term efficacy of concomitant CM procedures. METHODS: The study sample consisted of 709 concomitant CM-treated patients operated on with cryothermal energy only (group 1; n = 386) or combination of cryothermal and bipolar radiofrequency (group 2; n = 323)...

OBJECTIVE: The Cox-Maze IV procedure has been shown to be an effective treatment for atrial fibrillation when performed concomitantly with other operations either via median sternotomy or right minithoracotomy. Few studies have compared these approaches in patients with lone atrial fibrillation. This study examined outcomes with sternotomy versus minithoracotomy in stand-alone Cox-Maze IV procedures at our institution. METHODS: Between 2002 and 2015, 195 patients underwent stand-alone biatrial Cox-Maze IV...

OBJECTIVE: Although the Cox-maze operation is the standard surgical procedure for permanent atrial fibrillation(AF), conversion to sinus rhythm is limited by patient characteristics, including the duration of AF, atrial size, and voltage of fibrillation waves. A surgical strategy based on structural alteration of the electrical substrates of AF is required to achieve better outcomes of AF surgery. Complex fractionated atrial electrogram (CFAE) plays an important role in the electrical substrate of AF...
