Abstract

The aim of the present study was to evaluate the effects of sinus rhythm recovery on long-term survival after radiofrequency (RF) ablation in patients with permanent atrial fibrillation (AF) undergoing surgery for mitral valve disease. This study included 173 consecutive patients (101 men and 72 women, age 67 ± 9 years) with AF and mitral valve disease who underwent RF ablation procedure associated with mitral valve surgery. Four patients died during hospitalization. At the 6-year follow-up, sinus rhythm was present in 68% of the surviving patients. Thirty-nine patients remained in persistent AF after hospital discharge. In patients with stable sinus rhythm, mortality (10 vs. 30%) and recurrent hospitalization were significantly lower than in patients with persistent AF, but functional capacity improved. The incidence of stroke was also lower in patients with stable sinus rhythm. A pre-operative higher right and left atrial area, pulmonary hypertension, and rheumatic disease were associated with the persistence of AF despite RF ablation. At multivariate analysis, only age and concomitant tricuspid valve repair were independently associated with mortality, whereas the right atria area and tricuspid valve repair were associated w...Continue Reading

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.

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.

Auditory Perception

Auditory perception is the ability to receive and interpret information attained by the ears. Here is the latest research on factors and underlying mechanisms that influence auditory perception.

Atrial Filbrillation

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