Anesthesia Management for Transapical Transcatheter Aortic Valve Implantation: A Case Series

Objective The purpose of this study was to review the management of anesthesia for transapical transcatheter aortic valve implantation. Design Retrospective review of collected data. Setting University-affiliated heart center. Participants One hundred consecutive patients with severe aortic stenosis. Interventions General anesthesia followed by an established fast-track protocol. Materials and Methods A total of 100 patients with significant AS received transapical transcatheter aortic valve implantation. The patients were treated following a fast-track protocol. The mean arterial pressure was maintained above 65 mmHg by volume and/or inotropes during the procedure. The mean arterial pressure was increased above 75 mmHg to avoid hemodynamic deterioration before starting rapid ventricular pacing for the balloon valvuloplasty and the valve implantation. Transesophageal echocardiography was used to assess valve size and for hemodynamic monitoring. Eighty-one patients were treated completely off pump. There was a significant decline in mean arterial pressure from pre- to postvalvuloplasty (74.7 ± 9.1 mmHg v 63.6 ± 11.3 mmHg, p < 0.001) and from pre- to postimplantation (76.5 ± 12.6 mmHg v 67.2 ± 12.7, p < 0.001). The first 10 patients in the study intentionally were placed on cardiopulmonary bypass, and 9 patients required cardiopulmonary bypass because of hemodynamic deterioration. Conclusion A well-designed anesthetic plan as well as an understanding of the surgical procedure and the hemodynamic effects of rapid ventricular pacing are required to ensure successful outcomes in this new surgical option for high-risk patients.
