Atrial mechanical function following an intraoperative linear radiofrequency procedure for atrial fibrillation

Specific linear left atrial lesions in atrial fibrillation: intraoperative radiofrequency ablation using minimally invasive surgical techniques.

OBJECTIVES A specific left atrial (LA) linear lesion concept for treatment of paroxysmal and permanent atrial fibrillation (AF) was tested using intraoperative ablation with minimally invasive surgical techniques. BACKGROUND Curative treatment for patients with chronic AF is among the main challenges of interventional electrophysiology. METHODS Seventy patients (mean age 53 +/- 10 years) wi...

intraoperative radiofrequency and cryoablation for atrial fibrillation in patients with valvular heart disease

patients with valvular heart disease and suffering atrial fibrillation of more than 12 months duration have a low probability of remaining in sinus rhythm after valve surgery alone. we performed intra-operative radiofrequency ablation or cryoablation as an alternative to surgical maze ііі procedure to create linear lesion lines for conversion of this arrhythmia to sinus rhythm. a total of 30 pa...

Radiofrequency ablation for atrial fibrillation

Esophageal injury following radiofrequency ablation for atrial fibrillation: injury classification.

Pre-operative left atrial mechanical function predicts risk of atrial fibrillation following cardiac surgery.

OBJECTIVES The purpose of this study was to examine whether left atrial (LA) mechanical function, as measured by LA total emptying fraction (TEF), is a predictor for the development of post-operative atrial fibrillation (POAF) following cardiac surgery. BACKGROUND POAF is an important and frequent complication of cardiac surgery. LA enlargement has been reported to be a risk factor for POAF, ...
