Comparison of Patient Outcomes of Transfemoral Transcatheter Aortic Valve Replacement Using Pre-Sedation Radial Versus Post-Sedation Femoral Arterial Sites for Blood Pressure Monitoring

To compare outcomes among patients with and without preprocedural radial arterial catheters who underwent transfemoral transcatheter aortic valve replacement (TF-TAVR) under deep intravenous (IV) sedation and to assess predictive variables for preprocedural placement. Single-center, retrospective, cohort analysis. Department of Anesthesiology, Pain Management and Perioperative Medicine, Henry Ford Hospital, which is a tertiary care, university-affiliated hospital. The study comprised 157 patients. The primary focus was the 106 patients who underwent TF-TAVR when routine placement of preprocedure radial arterial catheters was abandoned. They were analyzed for hospital length of stay, 30-day mortality, and predictive factors of preprocedure placement. The remaining patients served as historical controls when routine radial artery catheter placement was practiced. Patient, procedure, and provider factors were analyzed. The transitional period consisted of 169 consecutive days from April 13 to September 28, 2017. A reference group of historical patients served as a control. Seventy-five of 106 patients did not have a preprocedural radial arterial catheter. The primary outcome measures of length of stay and 30-day mortality within the transitional group were not different. Secondary outcome measures included identification of predictive variables for preprocedure placement and outcome comparisons between the transitional and historical groups. Anesthesia provider (p = 0.015) and ejection fraction (p = 0.039) were significant factors. There were no differences in outcome measures. There was no difference in primary outcomes in patients with or without radial arterial catheters for TF-TAVR. The findings of this study suggest anesthesia provider and ejection fraction were significant factors for preprocedural placement.
