Incidence and Predictors of Stroke and Silent Cerebral Embolism Following Very High-Power Short-Duration Atrial Fibrillation Ablation.

ABSTRACT:

Background and aims

Cerebral thromboembolism is a dreaded complication of pulmonary vein isolation (PVI) for atrial fibrillation (AF); its surrogate, silent cerebral embolism (SCE) can be detected by diffusion-weighted brain magnetic resonance imaging (bMRI). Initial investigations have raised a concern that very high-power, short-duration (vHPSD; 90W/4 sec) temperature-controlled PVI with the QDOT Micro catheter may be associated with a higher incidence of SCE compared to low-power long-duration ablation (LPLD). We aimed to assess the incidence of procedural complications of vHPSD PVI with an emphasis on cerebral safety.

Methods

We enrolled 328 consecutive patients undergoing their PVI procedure using vHPSD. A subgroup of 61 consecutive patients underwent diffusion-weighted
