Outcome of patients undergoing TAVR with and without the attendance of an anesthesiologist

Background During the last few years there is a shift from performing Transcatheter Aortic Valve Replacement (TAVR) under general anesthesia towards conscious sedation and local anesthesia only. In the vast majority of centers, sedation is guided by a qualified anesthesiologist. In our center, all TAVR procedures are being performed under local anesthesia and mild sedation, however, since September 2014, a large portion of TAVR procedures are being performed under local anesthesia without the presence of an anesthesiologist. Here we compare 30 days outcome of patients undergoing TAVR with and without the presence of anesthesiologist in the catheterization laboratory. Methods and results From September 2014 through April 2016, 324 patients (mean age 82.8 ± 6) with severe symptomatic aortic stenosis were assigned to transfemoral TAVR with (150 patients) or without (174 patients) the attendance of an anesthesiologist. Baseline clinical and echocardiographic characteristics were similar between the groups. No difference in procedural and 30-day mortality, vascular complications, and major/life threatening bleeding were observed between the groups (p > 0.1, for all). Conclusions The presence of an anesthesiologist in the catheterization laboratory during transfemoral TAVR procedures did not significantly change 30-day outcome.
