Pulmonary vein isolation (PVI) has become an accepted therapeutic strategy for AF.1 The cryoballoon (CB) ablation system has been introduced into clinical practice as a tool for a single-shot anatomical based-PVI, and a comparable efficacy of the CB ablation to radiofrequency (RF) ablation has been demonstrated in a prospective randomised study.2–4
The recently introduced second-generation CB …

Pulmonary hypertension (PH) is a chronic condition that is characterised by elevated pulmonary vascular pressures and can be caused by several disease processes (see Table 1).1 Regardless of the aetiology, PH is a progressive disease with a clinical course characterised by frequent decompensations in advanced stages and often a poor prognosis despite the development of novel therapeutic agents.2…

Atrial fibrillation (AF) is the most commonly encountered arrhythmia in clinical practice. The discovery that pulmonary veins (PV) play a prominent role in the pathogenesis of AF has revolutionised the management of AF. PV isolation has become the most widely used technique for treatment of paroxysmal AF. Since the initial discovery implicating PVs in AF pathogenesis, the mechanistic link between…

AF is the most common sustained arrhythmia, and carries an increased risk of cardiovascular and cerebrovascular complications. The latest estimates on the prevalence of AF portray an alarming scenario, with a steep increase in the number of people developing AF and prediction that the number affected will more than double in the next 40 years.1 Among the strategies to restore and maintain sinus…

Atrial fibrillation (AF) is the most common sustained tachyarrhythmia. Catheter ablation is the most effective treatment for AF, and pulmonary vein isolation (PVI) is the cornerstone of all AF ablation strategies. The use of a radiofrequency (RF) catheter in combination with a 3D electro-anatomical mapping system is the most well established approach to AF ablation. However, manipulating a RF…

EHRA 2023 — Dr Vivek Y Reddy (Mount Sinai Hospital, US) shares the details of a study looking at conformable PVI catheters for pulmonary vein isolation (PVI). The study investigates the use of a highly deformable mesh-like eight-french catheter that has recently received CE mark approval. The trial is ongoing at three centers.

The most common sustained cardiac arrhythmia is AF, which is associated with increased risk of stroke and heart failure, and represents a significant global health burden.1 Pulmonary vein isolation (PVI) is the standard treatment for symptomatic, drug resistant paroxysmal and persistent AF.2 Radiofrequency (RF) ablation, the most widely used ablation technique, aims to achieve circumferential…

In this short video from Arrhythmia Academy's Journal Club, Prof Roland Tilz (University Heart Centre Lübeck, Lübeck, DE) and Prof Josef Kautzner (Institute for Clinical and Experimental Medicine, Prague, CZ) sit down to discuss the use of short-duration-ablation for pulmonary vein isolation (PVI). Prof Tilz provides a 10-minute presentation overview of VHPSD ablation technologies, including…

Catheter ablation of AF has become an established therapy and may have the potential to cure this most commonly encountered sustained arrhythmia. Previous studies have demonstrated that pulmonary veins (PVs) are a major source of the ectopic beats that initiate AF. PV isolation in patients with symptomatic paroxysmal AF refractory to antiarrhythmic drugs is effective; however, it is difficult to…
