Background: To report a long-term single-site experience of the cut-and-sew Cox maze III procedure for atrial fibrillation (AF).

Methods: A total of 232 consecutive patients underwent the Cox maze III procedure for symptomatic therapy-refractory AF, with concomitant surgery in 34 patients. Follow-up data were obtained from electrocardiograms, patient visits, questionnaires, and medical files.

Background: The cut-and-sew Cox-maze III procedure is the gold standard for surgical treatment of atrial fibrillation. The aim was to study early and long-term mortality based on registry analyses in Swedish Cox-maze III patients.

Methods: Preoperative and early postoperative data were analyzed in 536 patients (male/female (425/111), mean age 57 ± 8.

Atrial fibrillation (AF) is a common arrhythmia among patients scheduled for open heart surgery and is associated with increased morbidity and mortality. According to international guidelines, symptomatic and selected asymptomatic patients should be offered concomitant surgical AF ablation in conjunction with valvular or coronary surgery. The gold standard in AF surgery is the Cox Maze III ("cut-and-sew") procedure, with surgical incisions in both atria according to a specified pattern, in order to prevent AF reentry circuits from developing.

Purpose: To explore the effects on atrial and ventricular function of restoring sinus rhythm (SR) after epicardial cryoablation and closure of the left atrial appendage (LAA) in patients with mitral valve disease and atrial fibrillation (AF) undergoing surgery.

Methods: Sixty-five patients with permanent AF were randomized to mitral valve surgery combined with left atrial epicardial cryoablation and LAA closure (ABL group, n = 30) or to mitral valve surgery alone (control group, n = 35). Two-dimensional and Doppler echocardiography were performed before and 6 months after surgery.

Objectives: To assess the effects of intraoperative left atrial epicardial cryoablation on rhythm and atrial and ventricular function.

Design: Thirty five patients with coronary artery disease and documented atrial fibrillation underwent coronary artery bypass surgery and concomitant cryoablation. An age and gender matched control group of 35 patients with atrial fibrillation underwent bypass surgery alone.

Non-inferiority trials are questionable when death and serious complications are included among outcomes. The term itself "non-inferiority" is misleading, since such a study would not demonstrate that a new treatment is non-inferior to a control treatment, but simply that the inferiority would not reach a pre-specified level, deemed as acceptable by the designers of the trial. Group cross-over, assay-sensitivity and the need of a placebo arm are major issues for the reliability of non-inferiority trials.

Background: Left ventricular (LV) diastolic function and right atrial (RA) size are not routinely included in preoperative echocardiographic examination in patients undergoing cardiac surgery with concomitant ablation for atrial fibrillation (AF).

Objective: To investigate the role of echocardiographic variables including LV diastolic function and RA area in long-term rhythm outcome prediction, in patients with documented AF undergoing intraoperative ablation concomitant to coronary artery bypass grafting (CABG).

Methods: Thirty-five consecutive patients, scheduled for CABG, and with a history of paroxysmal or permanent AF for 8.

Objectives: : This meta-analysis sought to determine whether surgical ablation improves clinical outcomes and resource utilization compared with no ablation in adult patients with persistent and permanent atrial fibrillation (AF) undergoing cardiac surgery.

Methods: : A comprehensive search was undertaken to identify all randomized (RCT) and nonrandomized (non-RCT) controlled trials of surgical ablation versus no ablation in patients with AF undergoing cardiac surgery up to April 2009. The primary outcome was sinus rhythm.

Objective: : This purpose of this consensus conference was to determine whether surgical atrial fibrillation (AF) ablation during cardiac surgery improves clinical and resource outcomes compared with cardiac surgery alone in adults undergoing cardiac surgery for valve or coronary artery bypass grafting.

Methods: : Before the consensus conference, the consensus panel reviewed the best available evidence, whereby systematic reviews, randomized trials, and nonrandomized trials were considered in descending order of validity and importance. Evidence-based statements were created, and consensus processes were used to determine the ensuing recommendations.

Objective: The aim of the study was to compare energetic metabolism in the myocardium during coronary surgery with and without cardiopulmonary bypass by means of microdialysis.

Methods: Twenty-six low-risk patients were prospectively randomized to off-pump versus on-pump surgery. Microdialysis was used to sample myocardial interstitial fluid during and for 23 hours after surgery.

Aims: Our aim was to compare the long-term effects on rhythm and quality of life (QoL) after left atrial epicardial radiofrequency (RF) ablation vs. no ablation in patients undergoing cardiac surgery.

Methods And Results: Thirty-nine patients with ECG documented atrial fibrillation (AF) scheduled for coronary artery bypass grafting (CABG) with or without concomitant valve surgery were consecutively elected for epicardial RF ablation.

Objectives: We sought to assess the clinical and survival benefit of atrial fibrillation surgery in patients submitted to mitral valve surgery after stabilization of postoperative rhythm at 1 year.

Methods: One thousand seven hundred twenty-three patients were enrolled. Patients with follow-up of longer than 1 year (n = 972) were divided into 3 groups according to surface electrocardiographic rhythm during follow-up visits: stable sinus rhythm, stable atrial fibrillation, and intermittent rhythms.

Aims: The efficacy of epicardial left atrial (LA) cryoablation in eliminating atrial fibrillation (AF) in patients undergoing mitral valve surgery (MVS) is unknown. We hypothesized that MVS combined with LA cryoablation is superior to MVS alone.

Methods And Results: Sixty-nine patients with permanent AF, included at four centres, underwent MVS with or without epicardial LA cryoablation.

Background: Health care consumption and costs for the treatment of atrial fibrillation are high. Atrial fibrillation is effectively treated by the surgical Maze III procedure according to the Cox method. We describe the effects of this procedure on health care consumption and economy.

Metabolic surveillance of the myocardium is of great interest in cardiac surgery. Microdialysis allows sampling of chemical substances from the interstitial fluid for immediate analysis. The two objectives of this study were to develop a technique for simple and safe implantation of a commercially available microdialysis probe (CMA-70) into the myocardium and to obtain reference data for further use and metabolic control.

Background: Cardiac surgery induces a systemic inflammatory activation and alterations in the hemostatic cascade. The responses contribute to postoperative complications but may also have protective effects. We investigated the relationship between inflammation, hemostasis and bleeding after off-pump coronary artery bypass surgery (OPCAB).

Objective: To investigate the time course of troponin-T release into the extracellular fluid of the myocardium and to distinguish between a rise in troponin-T due to implantation trauma and an increase due to cardiac arrest during coronary surgery.

Design: Microdialysis probes were implanted in the heart of seven patients soon after sternotomy. Troponin-T was measured in the microdialysates and in peripheral blood from 3 h before to 24 h after heart arrest.

The interstitial fluid of the human myocardium was monitored in 13 patients undergoing aortic valve and/or bypass surgery before, during, and after hypothermic potassium cardioplegia. The regulation of glucose and lactate was studied after sampling with microdialysis. The following questions were addressed.

The sutureless aortic connector system was recently developed to create anastomoses between the aorta and saphenous vein grafts for coronary artery bypass grafting. Ten consecutive patients scheduled for coronary artery bypass grafting were studied; in each patient one proximal anastomosis was performed using the aortic connector and another was sutured in the conventional manner to serve as the patient's own control. One graft in the sutured group had a significant stenosis and one of the grafts in which the aortic connector was used, was occluded.
