Utilizing Fusion Imaging Technology in Aspiration Thrombectomy and Transcatheter PFO Closure: A Novel Approach

Impending paradoxical embolism (IPDE) through a patent foramen ovale (PFO) is extraordinarily rare, requiring rapid recognition and treatment to save lives. We present the case of a 45-year-old female with postthrombectomy IPDE through PFO. A multidisciplinary team decided to proceed with percutaneous aspiration thrombectomy followed by transcatheter PFO closure, guided by fusion imaging (FI) technology (EchoNavigator). The outcome was highly successful, with no further thrombosis and a well-seated occluder after the procedure, and demonstrated excellent results. To our knowledge, this is the first case reported using FI technology in a combined procedure of aspiration thrombectomy and PFO closure. We strongly encourage further research to explore the management of IPDE through PFO and assess the benefits of FI technology in comparison to conventional interventions for such procedures.
