Sex differences in ventricular arrhythmia: epidemiology, pathophysiology and catheter ablation [PDF]

Reviews in Cardiovascular Medicine, 2022
Evidence on sex differences in the pathophysiology and interventional treatment of ventricular arrhythmia in ischemic (ICM) or non-ischemic cardiomyopathies (NICM) is limited.

Ablation technologies

Surgery Open Science, 2022
Ablative therapies have recently emerged as an alternate to the gold-standard liver resection in treatment of malignant liver tumors. These modalities include radiofrequency ablation and microwave ablation which utilize thermocoagulative energy and microwave energy, respectively, to create a complete necrosis zone encircling the lesion. In this review,

Pulsed Field Ablation for the Treatment of Atrial Fibrillation: PULSED AF Pivotal Trial

Circulation, 2023
Background: Pulsed field ablation uses electrical pulses to cause nonthermal irreversible electroporation and induce cardiac cell death. Pulsed field ablation may have effectiveness comparable to traditional catheter ablation while preventing thermally ...

O-23 HEPATITIS B VIRUS STATUS OF ORGAN DONORS IN ARGENTINA

Annals of Hepatology, 2023
Introduction and Objectives: Argentina is considered an area with a low prevalence of hepatitis B virus (HBV). However, the real prevalence of the disease is unknown. We aimed to study the prevalence of HBV in potential cadaveric donors.

Effect of MRI-Guided Fibrosis Ablation vs Conventional Catheter Ablation on Atrial Arrhythmia Recurrence in Patients With Persistent Atrial Fibrillation: The DECAAF II Randomized Clinical Trial.

Journal of the American Medical Association (JAMA), 2022
Importance Ablation of persistent atrial fibrillation (AF) remains a challenge. Left atrial fibrosis plays an important role in the pathophysiology of AF and has been associated with poor procedural outcomes.

O-12 CHARACTERIZATION AND UTILIZATION OF HCV-POSITIVE DONORS IN ARGENTINA

Annals of Hepatology, 2023
Introduction and Objectives: Increased utilization of hepatitis C virus (HCV)-positive organ donors has been endorsed as one of several ways to combat organ shortages. However, HCV-positive donors remain poorly characterized. This study aimed to evaluate

Determination of lethal electric field threshold for pulsed field ablation in ex vivo perfused porcine and human hearts

Frontiers in Cardiovascular Medicine, 2023
IntroductionPulsed field ablation is an emerging modality for catheter-based cardiac ablation. The main mechanism of action is irreversible electroporation (IRE), a threshold-based phenomenon in which cells die after exposure to intense pulsed electric ...
