Abstract

Background Transfemoral transcatheter aortic valve replacement (TF-TAVR) has enjoyed a rapid diffusion in the US and Europe, but the procedure is resource intensive. Objectives We sought to identify differences in resource utilization between a US and European center to ascertain opportunities for improvement in the performance of TF-TAVR. Methods All patients undergoing TF-TAVR using the Edwards SAPIEN valve series at the San Raffaele Hospital (Milan, Italy) and the Cleveland Clinic Foundation (Cleveland, OH) between January 2011 and December 2012 were included. Resource utilization was defined as preprocedural imaging, intraprocedural imaging, and personnel present during the procedure. Results A total of 158 patients from Cleveland and 113 from Milan were analyzed. Median logistic EuroScore (22.1 vs. 15.5, P = 0.013) and STS-PROM (8.9 vs. 5.0%, P < 0.001) were higher in Cleveland. Thirty-day outcomes were similar. Majority of procedures in Milan were conducted without a cardiac surgeon (79%) or an imaging specialist (99%) present during the case. There was greater reliance on endotracheal intubation (94.3 vs. 3.5%), general anesthesia (GA: 94.3 vs. 4.4%), and intraprocedural TEE (93 vs. 12.4%) in Cleveland, but shorter length of stay (mean: 6.42 vs. 11.16 days). Conclusions We characterized resources used for patients undergoing TF-TAVR in Cleveland and Milan. Important differences included less reliance on GA and TEE and streamlining of procedural personnel in Milan, and reduced length-of-stay in Cleveland. Evolution of TF-TAVR to involve fewer operators must be balanced with the need for ready access to a comprehensive group of specialists in case of emergencies.
