The size-adjustable cryoballoon (POLARx™ FIT), expandable to 31 mm, was developed to improve occlusion; however, downsizing to a 28-mm balloon is sometimes required. The impact of PV morphology, particularly ovality, on occlusion performance remains unclear.</div></div><div><h3>Methods</h3><div>In vitro PV models with long-axis diameters of 30 mm and 24 mm were created, each including multiple ovality indices. Occlusion was assessed using 28-mm and 31-mm POLARx™ FIT cryoballoons. Intraluminal PV pressure was measured as an index of occlusion efficacy, with three repeated measurements averaged for each model.</div></div><div><h3>Results</h3><div>For the 31-mm balloon, a significant negative correlation was observed between ovality index and PV pressure in both model sizes (p < 0.0001), indicating reduced occlusion with increasing ovality.

In 24-mm models, the 28-mm balloon achieved higher and more consistent pressures.</div></div><div><h3>Conclusion</h3><div>Pre-freeze mechanical occlusion differed according to balloon size and PV geometry. The 31-mm balloon performed best in larger, more circular veins, whereas the 28-mm balloon showed more uniform performance across varying shapes, likely reflecting differences in stiffness and compliance.

We report an extremely rare case of late-onset, incessant monomorphic VT driven by abnormal Purkinje automaticity. A 77-year-old male, two years post-inferoposterior MI, presented with symptomatic VT and an exceptionally high premature ventricular contraction (PVC) burden of 29.1 %. The VT's mostly regular rhythm with occasional irregularity, combined with a reduced left ventricular ejection fraction (LVEF) of 48 %, suggested a continuous focal driver with intermittent exit block causing tachycardia-induced cardiomyopathy. High-density mapping revealed a centrifugal activation pattern, with the earliest site showing long, fractionated diastolic potentials adjacent to Purkinje potentials. A targeted regional substrate ablation strategy (\"de-networking\") of the arrhythmogenic substrate successfully terminated the arrhythmia. Consequently, the PVC burden was reduced to 1.5 % and the LVEF recovered to 54 % at one-month follow-up. This case demonstrates that late-onset, incessant VT from a surviving Purkinje network is a curable cause of cardiomyopathy, with targeted ablation leading to arrhythmia suppression and significant ventricular function recovery.</div></div>","PeriodicalId":35900,"journal":{"name":"Indian Pacing and Electrophysiology Journal","volume":"26 1","pages":"Pages 30-34"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146041602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
