Multiphase super-resolution CT imaging demonstrated that peri-device leaks following Watchman implantation exhibit dynamic variation across the cardiac cycle, becoming conspicuous during systole.

Super-resolution multiphase cardiac CT reveals that peri-device leaks can demonstrate dynamic variation with the cardiac cycle, highlighting the need for multiphase acquisition for accurate detection.
Nagpal et al. (2026) conducted a case report in Paroxysmal atrial fibrillation with prior Watchman device implantation (n=1). Super-resolution CT imaging (Precise IQ Engine, PIQE) with 1024 matrix was evaluated on Detection of peri-device leak (PDL). Multiphase super-resolution CT imaging demonstrated that peri-device leaks following Watchman implantation exhibit dynamic variation across the cardiac cycle, becoming conspicuous during systole.
