Simultaneous Transcatheter Aortic Valve Implantation and Left Atrial Appendage Occlusion versus both Interventions as Stand-Alone Procedures

ABSTRACTBackground: Patients with atrial fibrillation undergoing transcatheter aortic valve implantation (TAVI) have a worse prognosis than those in sinus rhythm. The bleeding risk associated with oral anticoagulation accounts for some of this difference. Left atrial appendage occlusion (LAAO) omits the need for oral anticoagulation in patients with atrial fibrillation. We investigated the feasibility of simultaneous TAVI and LAAO with Lotus and Watchman and compared the results to both interventions as stand-alone procedures.Methods: Fifty-two consecutive patients who underwent either TAVI with Lotus (n = 19), LAAO with Watchman (n = 23) or both procedures simultaneously (n = 10) were investigated. Procedural characteristics, in-hospital- and 30-day-outcomes defined by VARC-2 criteria were compared.Results: There was no significant difference in the amount of contrast medium used between the three groups (TAVI: 89 ± 29 mL; LAAO: 98 ± 54 mL; TAVI + LAAO: 86 ± 29mL; p = 0.923). The total procedural time wa...
