Freedom from reintervention and aortic events
Freedom from valve, ascending aorta and arch reintervention at 5 years was similar with 98% for PEARS vs 94.6% for VSRR (p=0.1) (Kaplan-Meier estimate of freedom from aortic valve (AV) and ascending aorta/arch reintervention for total (A) and matched (B) cohorts, including 95% CIs. Graphs were truncated when less than 15% of patients remained at risk. PEARS, personalised external aortic root support; VSRR, valve-sparing root replacement.
