    THIS COMPLAINT IS FROM A LITERATURE SOURCE. THE FOLLOWING LITERATURE ARTICLE HAS BEEN REVIEWED: LIN Y, LIN Q, ZHAO L, LIANG X, LIU F, ZHAO Q. AN INTEGRATED APPROACH TO RADIOFREQUENCY ABLATION OF PARA-HISIAN ACCESSORY PATHWAYS IN PAEDIATRIC PATIENTS. HEART RHYTHM. 2026 JAN 8:S1547-5271(26)00017-2. DOI: 10.1016/J.HRTHM.2026.01.002. EPUB AHEAD OF PRINT. PMID: 41519350. BACKGROUND: PAEDIATRIC PARA-HISIAN ACCESSORY PATHWAY (PHAP) ABLATION CARRIES GREATER CHALLENGES THAN IN ADULTS DUE TO SMALLER KOCH¿S TRIANGLES. OBJECTIVES: WE AIMED TO DEVELOP AN ABLATION STRATEGY TO ENHANCE BOTH EFFICACY AND SAFETY IN THIS POPULATION. METHODS: THIS SINGLE-CENTRE RETROSPECTIVE STUDY INCLUDED 41 PAEDIATRIC PATIENTS (MEDIAN AGE 10 YEARS) BETWEEN JANUARY 2023 AND SEPTEMBER 2025. THE STRATEGY COMPRISED: (1) PACE-MAPPING VALIDATION OF VENTRICULAR INSERTION SITES IN MANIFEST PATH WAYS, USING ADENOSINE-INDUCED MAXIMAL PRE-EXCITATION AS A TEMPLATE; AND (2) SUBVALVULAR RETROFLEXION FOR CATHETER STABILISATION IN PATIENTS =10 KG. ENERGY DELIVERY WAS TITRATED WITH GUIDANCE FROM PARA-HISIAN PACING TO DISTINGUISH NEAR-FIELD HIS SIGNALS, AND ATRIAL OVERDRIVE PACING WAS USED TO MONITOR AV CONDUCTION DURING ANY JUNCTIONAL ACCELERATION. CONCLUSIONS: OUR INTEGRATED ABLATION STRATEGY EFFECTIVELY ADDRESSES THE UNIQUE CHALLENGES OF PAEDIATRIC PHAP ABLATION, ACHIEVING DURABLE EFFICACY AND HIGH PROCEDURAL SAFETY. LOT, MODEL, AND CATALOG NUMBER ARE NOT AVAILABLE, BUT THE SUSPECTED BWI DEVICE IS POSSIBLY ASSOCIATED WITH REPORTED ADVERSE EVENTS: SOFTER IRRIGATED CATHETER (THERMOCOOL¿, BIOSENSE WEBSTER), STIFFER CONTACT FORCE-SENSING CATHETER (SMARTTOUCH¿, BIOSENSE WEBSTER). OTHER BWI PRODUCTS: 3D ELECTROANATOMIC SYSTEM (CARTO, BIOSENSE WEBSTER). NON-BWI DEVICES: SR-0 LONG SHEATH (ABBOTT), AGILIS¿ STEERABLE SHEATH (ABBOTT), LABSYSTEM PRO MULTICHANNEL SYSTEM (BARD ELECTROPHYSIOLOGY). ADVERSE EVENT(S) AND PROVIDED INTERVENTIONS FOR BWI DEVICES: UNK_THERMOCOOL SF NON-NAV QTY 1: 1 CASE OF FIRST-DEGREE AV BLOCK TRANSIENT CONDUCTION DISTURBANCES. QTY 3: 3 CASES OF MOBITZ I CONDUCTION DISTURBANCES. QTY 12: 12 CASES OF JUNCTIONAL RHYTHM. ADVERSE EVENT(S) AND PROVIDED INTERVENTIONS FOR BWI DEVICES: UNK_SMART TOUCH UNIDIRECTIONAL. QTY 1: 1 PATIENT A 1 YEAR-OLD WAS FOUND TO HAVE A DEVELOPED A SUPERIOR MID-PARASEPTAL AP CASE, A PERSISTENT INCOMPLETE RIGHT BUNDLE BRANCH BLOCK DURING THE REVERSE-C MANOEUVRE, THIS DID NOT AFFECT COMPLETION OF THE PROCEDURE AND SHOWED NO PROGRESSION DURING FOLLOW-UP.
