[Transcatheter cerebral embolic protection in open heart surgery: our initial experience in Ancona, Italy].

BACKGROUND Neurological events after cardiac surgery or transcatheter aortic valve implantation (TAVI) have a dramatic effect on patients' prognosis. Recent development of transcatheter cerebral protection systems aims to reduce their incidence, even if their use is currently limited to TAVI. Here we report our initial experience with transcatheter cerebral protection devices used in patients at high brain embolic risk undergoing cardiac surgery. METHODS Between December 2018 and March 2020, at the Cardiac Surgery Unit of Lancisi Cardiovascular Center in Ancona, Italy, 9 patients (mean age 77 years; median EuroSCORE II: 2.2%) underwent cardiac surgery using a transcatheter cerebral protection system (Sentinel, Claret Medical, Santa Rosa, CA, USA). In all cases, a preoperative computed tomography scan highlighted the presence of severely calcified ascending aorta. RESULTS The brain protection system was successfully implanted in all patients. Total time for device implantation and removal was less than 10 min in all cases. Four patients underwent aortic valve replacement, 2 mitral surgery, whereas 3 received combined valve surgery. Calcified debris were found within filters in 100% of patients. Postoperatively, there were neither neurological events nor major complications. CONCLUSIONS In our experience, transferring transcatheter brain protection techniques and technologies to cardiac surgery allowed us (with excellent results) to avoid palliative percutaneous or medical management in patients with severe aortic calcifications. Waiting for more solid evidence, we believe that our example supports the concept of hybrid surgery as a therapeutic approach capable of extending traditional surgical indications with improved patients' outcomes.
