Optimization of the hot balloon ablation strategy using real-time pulmonary vein potential monitoring.

Real-time assessment of PV isolation can be achieved during HBAs with single-shot techniques. (TTI-TTRT)s <4.5 seconds and TTIs <33.5 seconds predicted for acute isolation. Ablation time after isolation >148.5 seconds in superior PVs and >120.5 seconds in inferior PVs were effective application durations.
