High-power short-duration ablation of the superior vena cava: safety and efficacy using the right superior pulmonary vein roof as a landmark

Using the RSPV roof and SVC junction as anatomical landmarks for SVC isolation may offer a safe and effective approach. Additionally, HPSD ablation (50 W/7 s) of the SVC was achieved without the use of routine PN mapping in this cohort, resulting in successful isolation and a low incidence of transient PNI. This suggests it may represent a potential alternative strategy; however, the occurrence of PNI underscores that techniques such as PN mapping remain crucial for risk mitigation.
