Does exchanging catheters over a single transseptal access increase the risk of silent cerebral events during left atrial ablation compared to using different transseptal accesses?
Using a single transseptal sheath and exchanging catheters during left atrial ablation is associated with a higher risk of silent cerebral events compared to using separate accesses.
Exchanging catheters over a single transseptal access to perform left atrial ablation is associated with a significantly higher incidence of SCE compared to an ablation technique using different transseptal accesses for therapeutic and diagnostic catheters.
Deneke et al. (Mon,) studied this question.
