Key result
A standardized approach using a horseshoe-shaped lesion set with optimized and contiguous ostial RF lesions achieved a very high rate of acute SVC isolation safely and in mostly less than 10 minutes.
Why the study?
The superior vena cava is one of the most common non-pulmonary vein triggers for atrial tachyarrhythmias, prompting evaluation of a standardized electrical isolation approach.
Does a standardized approach using a horseshoe-shaped lesion set with optimized and contiguous ostial RF lesions safely and efficiently achieve acute electrical isolation of the superior vena cava?
Observational
Does a standardized approach using a horseshoe-shaped lesion set with optimized and contiguous ostial RF lesions safely and efficiently achieve acute electrical isolation of the superior vena cava?
A standardized horseshoe-shaped RF lesion set provides a safe, time-efficient (mostly <10 min), and highly effective method for acute electrical isolation of the superior vena cava.
May support safe, efficient acute SVC isolation; leaves open long-term outcomes and need for randomized validation.
The superior vena cava (SVC) is well described as one of the most common non-pulmonary vein (PV)-triggers for atrial tachyarrhythmias (ATA). In our study we evaluated a standardized approach for electrical isolation of the SVC from the right atrium using a horseshoe-shaped lesion set with optimized and contiguous ostial RF lesions. The results are promising, demonstrating a very high rate of acute SVC isolation in a safe and time efficient manner (mostly less than 10 min).

Hilfiker et al. (2022) conducted an observational in Atrial tachyarrhythmias. Standardized approach for electrical isolation of the SVC using a horseshoe-shaped lesion set with optimized and contiguous ostial RF lesions was evaluated on Acute SVC isolation. A standardized approach using a horseshoe-shaped lesion set with optimized and contiguous ostial RF lesions achieved a very high rate of acute SVC isolation safely and in mostly less than 10 minutes.
