Real-world single-center preliminary experience of radiofrequency balloon pulmonary vein ablation for atrial fibrillation.
Indian Pacing Electrophysiol J

Atrial fibrillation (AF) is the most common cardiac arrhythmia and pulmonary vein isolation (PVI) by percutaneous transcatheter ablation is its pivotal treatment. Nowadays, several techniques using different energy sources are used, such as radiofrequency (RF), cryoablation and laser ablation. A new technology that combines the strengths of different techniques has been developed, in particular having both the speed of one-shot techniques and the selectivity and precision of point-by-point RF: the RF balloon (RFB).

Background: Pulsed field ablation (PFA) for paroxysmal atrial fibrillation (AF) has been gaining worldwide acceptance due to its efficacy and safety. A variable loop circular catheter (VLCC, VARIPULSE, Biosense Webster, Inc.) for PFA, recently launched in Japan, includes a Tissue Proximity Indication (TPI) feature to monitor catheter-tissue contact via impedance.

Since its first pathological description over 65 years ago, hypertrophic cardiomyopathy (HCM), with a worldwide prevalence of 1:500, has emerged as the most common genetically determined cardiac disease. Diagnostic work-up has dramatically improved over the last decades, from clinical suspicion and abnormal electrocardiographic findings to hemodynamic studies, echocardiography, contrast-enhanced cardiac magnetic resonance, and genetic testing. The implementation of screening programs and the use of implantable cardioverter defibrillators (ICDs) for high-risk individuals have notably reduced arrhythmic sudden deaths, altering the disease's mortality profile.

Background And Aim: Stent placement for biliary drainage in patients with malignant hilar biliary obstruction (MHBO) has been a topic of long-standing debate, and the best approach remains controversial. Therefore, we aimed to evaluate the efficacy, safety, and removability of multi-hole fully covered self-expandable metal stents (MH-FCSEMSs) in a preclinical experiment using swine hilar bile duct obstruction (HBDO) models and to assess the feasibility and safety of stent placement in patients with MHBO.
Methods: Three minipigs underwent endoscopic retrograde cholangiopancreatography (ERCP)-guided endobiliary-radio frequency ablation (EB-RFA) to establish Bismuth type II hilar bile duct stenosis models.
