Abstract

Catheter-based pulmonary vein (PV) isolation has emerged as established therapy for patients with paroxysmal atrial fibrillation (AF). The purpose of this study was to determine the results at 1-year follow-up after PV isolation was performed using a single novel multipolar catheter for mapping and ablation. Patients with paroxysmal AF were screened by cardiac computed tomography for anatomic suitability to undergo PV ablation with the Bard HD Mesh Ablator Catheter (MESH). PV isolation with the MESH was performed only in patients who matched the criteria of four clearly separated PVs with an ostial diameter of 15 to 25 mm. PV isolation with the MESH was performed in 36 (55%) of 65 screened patients. In all 36 patients, all PVs could be mapped with the MESH. Electrical isolation could be achieved in 135 (96%) of 140 PVs that revealed PV potentials. One-year follow-up was completed for 35 patients; one patient was lost to follow-up. Ten (29%) patients reported to be symptom-free and had no AF during three 48-hour ECGs, whereas 25 (71%) patients suffered from AF recurrences. Reablation performed in 11 patients revealed reconnection of three PVs in 6 patients and four PVs in 5 patients. The single-catheter approach using the MESH f...Continue Reading

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.

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.

Atrial Filbrillation

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

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.

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.
