Abstract

The electrical disconnection of the pulmonary veins (PV) plays an important role in the ablation strategy of paroxysmal atrial fibrillation (PAF). Circumferential antral ablation with a conventional ablation technique using a steerable ablation catheter is sometimes difficult to perform and does not always result in isolation of the targeted PV. Patients with symptomatic PAF were treated with a novel circular mapping/ablation catheter (PVAC). Ablation was performed in the antral region of the PV with a power-modulated bipolar/unipolar RF generator using 8-10 W until isolation of the vein was achieved. Seven-day Holter monitor recordings were performed off antiarrhythmic drugs at 3 and 6 months after the initial procedure. A subgroup of patients had received an implantable recorder before ablation, and the device was interrogated at the same time. The primary objective of this study is acute isolation of the targeted PV, and the second objective is clinical efficacy with a short-term follow-up. In 73 patients, 290 PV could be reached with the PVAC. Antral ablation was performed in 244 PV showing PV potentials. Acutely, 243 PV (99%) were isolated with the PVAC after 21+/-7 energy applications per patient with a mean fluoroscopy t...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.

Cardiac Conduction System

The cardiac conduction system is a specialized tract of myocardial cells responsible for maintaining normal cardiac rhythm. Discover the latest research on the cardiac conduction system 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.
