Open Surgical Access for Transfemoral TAVR Should Not Be a Contraindication for Conscious Sedation.

OBJECTIVES

The use of monitored anesthesia care (MAC) for transcatheter aortic valve replacement (TAVR) is gaining favor in the United States, although general anesthesia (GA) continues to be common for these procedures. Open surgical cutdown for transfemoral TAVR has been a relative contraindication for TAVR with MAC at most centers. The objective of this study was to review the authors' results of transfemoral TAVR performed in patients with open surgical cutdown with the use of MAC.

DESIGN

Retrospective study design from a prospectively recorded database.

SETTING

Tertiary academic (teaching) hospital.

PARTICIPANTS

Two hundred eighty-two patients undergoing transfemoral TAVR with open surgical cutdown under MAC from 2015 to 2017.

INTERVENTIONS

Transfemoral TAVR under MAC with surgical cutdown for femoral vascular access.

MEASUREMENTS AND MAIN RESULTS

The study cohort consisted of 282 patients with severe aortic stenosis (mean area 0.65 [± 0.16] cm, mean gradient of 48.9 [±13.3] mmHg, and mean age of 82.7 [± 7.31] years). Eleven (3.9%) patients required conversion to GA. First postoperative pain score (0-10) was 2.9 and highest postoperative pain score was 4.6. Major and minor vascular complications occurred in 2 (0.7%) and 6 (2.1%) patients, respectively. Twenty-nine (10.3%) patients were readmitted within 30 days, and 6 (2.1%) patients had in-hospital mortality.

CONCLUSIONS

Open surgical cutdown for transfemoral TAVR can be performed safely using MAC and ilioinguinal block with low rates of conversion to general anesthesia and acceptable postoperative outcomes and pain scores.
