Pulmonary vein isolation (PVI) with cryoballoon (CB) ablation technology is widely used to treat drug-resistant atrial fibrillation (AF). During CB ablation, there is a possibility of forming an ice cap of contrast-color on top of the balloon. If automatic balloon deflate occurs before the ice cap dissolves, embolization to the systemic circulation is possible.

We report a case of a patient with dilated cardiomyopathy who experienced recurrent ventricular tachycardia (VT) and multiple defibrillations following CRT-D implantation. Due to worsening cardiac function, the patient required surgical implantation of a left ventricular assist device (LVAD) as a bridge to heart transplantation. During the procedure, we used the Ensite three-dimensional mapping system to perform activation and substrate mapping of the VT targets, followed by endocardial and epicardial cryoballoon ablation of clinical VT.

Background And Aims: Early rhythm-control therapy in atrial fibrillation (AF) results in higher freedom from atrial arrhythmia (AA) recurrence and improved cardiovascular outcomes. The optimal timing of Cryoballoon ablation (CBA) is unknown.
Methods: We evaluated AA recurrence and procedure-related complications of early vs.

Introduction: A hybrid approach with very high-power short-duration (vHPSD) posteriorly and ablation-index guided HPSD (50 W) anteriorly seems to be an optimal balance between efficiency and effectiveness for point-by-point pulmonary vein isolation (PVI). The aim of the current study is to compare vHPSD/HPSD ablation to cryoballoon ablation (CBA) in patients with symptomatic atrial fibrillation (AF).
Methods And Results: In this retrospective single-center study, we identified 110 consecutive patients who underwent their first PVI with either vHPSD/HPSD (n = 54) or CBA (n = 56).
