Abstract

Left atrial surgical radiofrequency ablation represents an applicable and technically less demanding method for treating paroxysmal or permanent atrial fibrillation (AF) as a concomitant procedure. The aim of this study was to review the long-term outcomes of radiofrequency linear ablation for the treatment of AF limited to the left atrium in 3 groups of patients undergoing cardiac surgery. The study population consisted of 357 consecutive patients, who were divided into 3 groups on the basis of the underlying disease: group I, 126 patients with nonischemic mitral valve disease; group II, 164 patients with coronary artery disease and aortic and/or ischemic mitral valve disease or who underwent other concomitant procedures; and group III, 67 patients with coronary artery disease only. Follow-up times were between 6 and 48 months (mean, 28.3 + 9.4 months). The 30-day hospital mortality rate was 2.80% (10 patients). Total mortality during the follow-up period reached 4.48% (16 patients). At discharge, 66% of group I patients, 64% of group II patients, and 69% of group in patients were in sinus rhythm. After 24 months, 60% of group I patients, 75% of group II patients, and 67% of group III patients were in sinus rhythm. A subgroup ...Continue Reading

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
