Abstract

Background: Dialysis patients with aortic stenosis are generally considered as being at extreme or high surgical risk. Herein, the first clinical trial was conducted to investigate clinical safety and effectiveness of transcatheter aortic valve replacement (TAVR) using the balloon-expandable transcatheter aortic valve (SAPIEN 3, Edwards Lifesciences, Irvine, CA, USA) in Japanese dialysis patients. Methods: The clinical trial is a single arm, prospective, open, non-randomized, Japanese multicenter study. The primary purpose of this trial is to evaluate the efficacy and safety of TAVR using SAPIEN 3 in 28 Japanese dialysis patients. Results: Mean age was 79.2 years and 67.9% were male (Mean STS score was 14.3%). Transfemoral and transapical approaches were performed in 25 (89.3%) and 3 patients (10.7%), respectively. All bioprostheses were successfully implanted. Median intensive care unit stay and hospital stay after TAVR were 1.4 days and 6.3 days, respectively. In-hospital mortality was 3.6% and freedom from all-cause mortality at 1 year was 89.3%. Disabling stroke and life-threatening bleeding at 1 year was 7.7% and 8.5%, respectively. There was no structural valve deterioration during follow-up. New York Heart Association functional status, six-minute walk test, and EuroQOL visual analogue scale score significantly improved through 1 year compared with baseline. Conclusions: TAVR using SAPIEN 3 is safe and effective for the treatment of Japanese dialysis patients with symptomatic severe aortic valve stenosis.
