By Magnus Nossen, edits by Grauer and Smith The patient is a 70-something female with DMII, HTN and an extensive prior history of coronary artery disease and myocardial infarctions. She's had multiple PCI procedures. She also has sick sinus syndrome (SSS) and intermittent high grade AV block for which she had a dual chamber pacemaker implanted. On the day of presentation she complained of typical chest pain, and stated it feels like prior MI.

Abstract Introduction Influence of early atrial fibrillation (AF) ablation, particularly cryoballoon ablation (CBA), on clinical outcome during long-term follow-up has not been clarified. The objective was to determine whether an early CBA (diagnosis-to-ablation of ≤6 months) strategy could affect freedom from AF recurrence after index CBA. Methods The study included 2605 patients from Korean CBA registry data with follow-up >12 months after de novo CBA.

In this meta-analysis, left atrial appendage occlusion (LAAO) using intracardiac echocardiography (ICE) guidance resulted in a similar procedural safety and efficacy as transesophageal echocardiography (TEE) guidance. ICE-guidance resulted in shorter in-room time, without significant differences in procedural and fluoroscopy time. During follow-up, there was no difference in peri-device leaks, with a significantly higher risk of residual interatrial septal defects in the ICE-guided group.

Abstract Introduction Carina breakthrough (CB) at the right pulmonary vein (RPV) can occur after circumferential pulmonary vein isolation (PVI) due to epicardial bridging or transient tissue edema. High-power short-duration (HPSD) ablation may increase the incidence of RPV CB. Currently, the surrogate of ablation parameters to predict RPV CB is not well established.
