Abstract

OBJECTIVES: Favourable results have been reported for monitored anaesthesia care that includes local anaesthesia and conscious sedation [minimalist approach (MA)] for transfemoral transcatheter aortic valve replacement (TAVR). However, the efficacy of MA is still controversial in Japan. We describe our experience from a Japanese multicentre registry. METHODS: Between October 2013 and April 2016, 1215 consecutive Japanese patients with symptomatic, severe aortic stenosis undergoing TAVR with self-expandable or balloon-expandable valves were prospectively included in the Optimized transCathEter vAlvular intervention-Transcatheter Aortic Valve Implantation (OCEAN-TAVI) registry. Of these patients, we retrospectively reviewed 921 consecutive patients who underwent elective transfemoral-TAVR. We evaluated the perioperative results of MA-TAVR and non-minimalist approach (NMA) TAVR using propensity score matching analysis. RESULTS: A total of 118 patients underwent MA-TAVR, and 802 patients underwent NMA-TAVR [median age 84 vs 85 years, P = 0.25; Society of Thoracic Surgeons (STS) score 7.6 vs 6.4, P = 0.01]. One hundred eighteen matched pairs were compared after propensity score matching. In-hospital mortality and stroke/transient ischaemic attack were not significantly different between the MA-TAVR and the NMA-TAVR groups (2.5% vs 0.8%, P = 0.3; 1.7% vs 0.8%, P = 0.6, respectively). Major or life-threatening bleeding and the transfusion rate were significantly lower in the MA-TAVR group (3.4% vs 17%, P = 0.003; 6.8% vs 29%, P = 0.0002, respectively). The total intensive care unit days and length of hospital stay were significantly lower in the MA-TAVR group (P < 0.0002). CONCLUSIONS: MA-TAVR has similar results to NMA-TAVR in terms of mortality and stroke in this Japanese multicentre registry. Shorter procedure time and hospital stays were seen in the MA-TAVR group. MA-TAVR is as safe and effective as NMA-TAVR.
