Second-generation cryoballoons (2-CBs) are widely used in atrial fibrillation (AF) ablation, however, the optimal freeze dose is still under debate. Recently, the time-to-isolation (TTI), which is the time until an acute pulmonary vein isolation (PVI), is noted based on clinical and experimental studies, and a TTI-guided strategy has been proposed. However, in real-world human CB procedures, the direct association between the TTI and PVI durability has not been well examined. We sought to investigate whether the TTI plus >120 second freezes, when the TTI is <60 seconds, accurately predicts a durable 2-CB ablation PVI.

Safety and efficacy outcomes of left atrial posterior wall isolation compared to pulmonary vein isolation and pulmonary vein isolation with linear ablation for the treatment of persistent atrial fibrillation.
Pulmonary wall isolation (PWI) is increasingly used as an adjunctive lesion set to compliment pulmonary vein isolation (PVI), especially in patients with persistent atrial fibrillation (AF). The objec...
Ablation index (AI) is useful to complete circumferential pulmonary vein isolation (CPVI) for atrial fibrillation (AF), but the role of radiofrequency power in AI-guided CPVI remains to be elucidated.
Pulmonary vein antrum isolation by radiofrequency ablation has become a preferred treatment for atrial fibrillation. The aim of our research is to study the anatomy of the PVantrum and its related str...
The significance of inducibility of atrial fibrillation (AF) after pulmonary vein isolation (PVI) in patients with AF remains disputable and polarizing. Therefore, we investigated the prognostic value...
Atrial fibrillation (AF) is a growing healthcare burden, for which pulmonary vein isolation (PVI) using cryoballoon (CB) or radiofrequency (RF) represent attractive therapies. Women are at higher risk...
The investigators prospectively investigate the differences between contact-force guided pulmonary vein isolation (PVI) and conventional pulmonary vein isolation in patients with paroxysma...
Comparison of Circumferential Pulmonary Vein Isolation Alone Versus Linear Ablation in Addition to Circumferential Pulmonary Vein Isolation for Catheter Ablation in Persistent Atrial Fibrillation: Prospective Randomized Controlled Trial
The purpose of this study is to compare the clinical outcomes depending on catheter ablation strategy for persistent atrial fibrillation. After randomization, investigators will conduct ci...
Comparison of Circumferential Pulmonary Vein Isolation and Complex Pulmonary Vein Isolation Additional Linear Ablation for Recurred Atrial Fibrillation After Previous Catheter Ablation: Prospective Randomized Trial (CALRA-AF)
The purpose of this study is to compare the clinical outcomes depending on catheter ablation strategy for repeat ablation procedure among the patients with recurred atrial fibrillation aft...
We conduct a randomized study comparing the safety and effectiveness of two interventional ablation techniques for treatment of paroxysmal atrial fibrillation: the segmental pulmonary vei...
Objective: This prospective study aims to examine the outcome of atrial fibrillation (AF) ablation after permanent pulmonary vein antrum isolation or pulmonary vein antrum isolation plus l...
The segregation of patients with communicable or other diseases for a specified time. Isolation may be strict, in which movement and social contacts are limited; modified, where an effort to control specified aspects of care is made in order to prevent cross infection; or reverse, where the patient is secluded in a controlled or germ-free environment in order to protect him or her from cross infection.
Restriction of freedom of movement of individuals who have been exposed to infectious or communicable disease in order to prevent its spread; a period of detention of vessels, vehicles, or travelers coming from infected or suspected places; and detention or isolation on account of suspected contagion. It includes government regulations on the detention of animals at frontiers or ports of entrance for the prevention of infectious disease, through a period of isolation before being allowed to enter a country.

The splitting of an ancestral species into daughter species that coexist in time (King, Dictionary of Genetics, 6th ed). Causal factors may include geographic isolation, MUTATION, migration, random GENETIC DRIFT, and HABITAT geometry.
Narrowing of the PULMONARY VEIN.
The separation and isolation of tissues for surgical purposes, or for the analysis or study of their structures.
