Abstract

Rhythm control is indicated for patients suffering from symptomatic atrial fibrillation (AF), but remains difficult to establish. We investigated the long-term outcome of Cox maze III surgery in patients with symptomatic lone AF refractory to antiarrhythmic drug therapy. Patients with a history of symptomatic paroxysmal or persistent AF refractory for at least two class I or III antiarrhythmic drugs and without structural heart disease or bradyarrhythmias were included. All patients underwent Cox maze III surgery. Complete success was defined as the absence of AF without antiarrhythmic drugs beyond 3 months after the procedure, and partial success as the absence of AF with antiarrhythmic drug use. A total of 29 patients were included (27 male), with a mean age of 48 +/- 6 years. At the time of surgery, 11 patients (38%) had persistent AF. After a mean follow-up of 4.8 +/- 2.4 years, 79% of patients had complete success, and 2 patients (7%) were free of AF with antiarrhythmic drugs. At the end of follow-up, left ventricular fractional shortening was significantly improved (from 31% +/- 10% to 39% +/- 8%, p = 0.002), left atrial size was unchanged, exercise capacity was within normal ranges, and quality of life was comparable wit...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.

Anti-Arrhythmic Drug Therapies

Anti-arrhythmic drugs are used to prevent abnormal heart rhythms. These medications are used in conditions including, ventricular tachycardia, ventricular fibrillation and atrial fibrillation. Discover the latest research on anti-arrhythmic drug therapies here.

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.

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs. Discover the latest research on Antiarrhythmic Agents: Mechanism of Action here.

Bradyarrhythmias

Bradyarrhythmias are slow heart rates. Symptoms may include syncope, dizziness, fatigure, shortness of breath, and chest pains. Find the latest research on bradyarrhythmias here.
