Key result
Minimally invasive Port-Access-assisted aortic valve replacement was safe and effective with equivalent clinical outcomes to conventional surgery, though it required significantly longer operative times (237 vs 190 minutes, p<0.001).

Absolute Event Rate: 237% vs 190%
p-value: p=<0.001
A hybrid, minimally invasive Port-Access approach to aortic valve replacement is safe and effective, offering equivalent postoperative outcomes to conventional sternotomy despite longer operative times.
Leshnower et al. (2006) conducted a cohort in Aortic valve disease requiring primary isolated aortic valve replacement (n=58). Minimally invasive Port-Access-assisted aortic valve replacement (MPAVR) vs. Conventional aortic valve replacement (CAVR) was evaluated on Total operative time (minutes) (p=<0.001). Minimally invasive Port-Access-assisted aortic valve replacement was safe and effective with equivalent clinical outcomes to conventional surgery, though it required significantly longer operative times (237 vs 190 minutes, p<0.001).
