Catheter Ablation: Evolution and Efficiencies

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT The present review includes a discussion the goals and pitfalls of efficiency in the medical profession, a historical perspective on the evolution of catheter ablation in the field of electrophysiology (EP), and the data regarding the relationship between efficiency and outcomes in the EP lab. Focus on efficacy is critical to maximize resource

Acute Effects on Signal-Averaged Electrogram Parameters and Suppressing Premature Ventricular Contractions in Single or Combined Use of Class I Antiarrhythmic Drugs

Journal of Arrhythmia, 2006
Disopyramide (DP), mexiletine (MX), and flecainide (FL) are class I antiarrhythmic drugs. However, these drugs exert different effects on the electrocardiogram (ECG) based on their unique actions on cardiac myocytes.

Clinical Utility of Tissue Proximity Indication With a Variable‐Loop Circular Catheter for Pulmonary Vein Isolation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background The variable‐loop circular catheter (VLCC, VARIPULSE) is a pulsed‐field ablation (PFA) catheter equipped with a Tissue Proximity Indication (TPI) function, which monitors catheter‐tissue contact. Although TPI‐negative sites have been reported to contribute to gap formation, no studies have evaluated the utility of real‐time function.

Time‐Dependent Diagnostic Yield and Therapeutic Impact of Implantable Loop Recorders, Brugada Syndrome as the Exception

Journal of Cardiovascular Electrophysiology, EarlyView.
Diagnostic yield and therapeutic impact varied substantially according to the indication for implantation. Actionable diagnoses were concentrated in the early follow‐up period for syncope and palpitations, whereas late atrial fibrillation detection after cryptogenic stroke could still modify antithrombotic management. In contrast, patients with Brugada

Antiarrhythmic drugs for atrial fibrillation: focus on dronedarone

, 2009
Patients with atrial fibrillation have an increased risk of stroke and heart failure, as well as impairment of their quality of life. Most trials have primarily focused on the prevention of stroke and heart failure, and the improvement of symptoms in ...

Brugada Syndrome in the Pediatric Population: Diagnostic Challenges and Clinical Outcome—Results of the German Multicenter Study COGIA

Journal of Cardiovascular Electrophysiology, EarlyView.
The study examines 76 patients of the German multicenter study COGIA with suspected BrS in 12 centers in Germany. Thirty‐nine patients met the current ESC diagnostic criteria, 34 of whom met the Shanghai Score criteria. Four major arrhythmic events (ACA, SCD, appropriate ICD shock) occurred in the cohort (5.3%), all in the group of patients fulfilling ...

Bilateral cardiac sympathetic denervation of a recurrent refractory ventricular tachycardia occurring after catheter ablation of atrial fibrillation and outflow tract premature ventricular contractions

Journal of Arrhythmia, 2019
Recent studies have demonstrated the utility of cardiac sympathetic denervation (CSD) in patients with ventricular tachycardia (VT) refractory to antiarrhythmic drugs and catheter or surgical ablation.

Feasibility, Safety, and Efficacy of Pulsed Field Ablation for Ventricular Arrhythmias: Insights From a Large Health System Registry in the United States

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Pulsed field ablation (PFA) is an emerging non‐thermal ablation modality with proven safety in atrial arrhythmia ablation. However, data on its performance for ventricular arrhythmias (VA) remain limited. Objective To evaluate the feasibility, safety, and efficacy of PFA for complex VA in a multicenter real‐world US registry ...
