Abstract

Ablation of arrhythmias arising from the papillary muscles (PAPs) is challenging. The purpose of this study was to assess the predictors of successful catheter ablation in patients with ventricular arrhythmias arising from the PAPs. Forty consecutive patients (15 women, mean age 51 ± 14 years, left ventricular ejection fraction 0.46 ± 0.13) with refractory PAP arrhythmias underwent mapping and ablation. Catheter stability was assessed with intracardiac echocardiography. Activation mapping and/or pace mapping were performed to identify the site of origin. Electrophysiological data and anatomic characteristics were assessed in patients with effective versus ineffective ablation. Catheter stability was assessed with intracardiac echocardiography. Radiofrequency ablation was acutely effective in eliminating the targeted arrhythmia in 31 patients (78%). The presence of Purkinje potentials at the site of origin of the targeted arrhythmia was associated with an effective outcome (48% vs. 0%; P = .01). The mass of the arrhythmogenic PAPs in the left ventricle was significantly larger in patients with failed versus effective ablation (4.7 ± 2.2 g vs. 2.3 ± 0.6 g; P < .0001). Also, the presence of a matching pace map at the earliest endo...Continue Reading

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.

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.

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.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

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.
