Among selected patients with native pure AR deemed at high risk for SAVR, TAVR is technically feasible and associated with an acceptable risk of early mortality.

The Perceval sutureless valve resulted in low 1-year event rates in intermediate-risk patients undergoing AVR. New York Heart Association class improved in more than three-quarters of patients and remained stable. These data support the safety and efficacy to 1 year of the Perceval sutureless valve in this intermediate-risk population.
