Key result
Minimally invasive parasternal aortic valve replacement had similar hospital mortality (5.9% vs 7.1%) but shorter median length of stay (5 vs 7 days) compared to standard sternotomy.

Does a minimally invasive parasternal approach improve surgical recovery and outcomes compared to standard sternotomy in patients undergoing primary isolated aortic valve replacement?
Absolute Event Rate: 5.9% vs 7.1%
Minimally invasive parasternal aortic valve replacement may reduce length of stay, blood loss, and pain compared to standard sternotomy, despite requiring longer cross-clamp times.
B Frazier (1998) conducted a cohort in Primary isolated aortic valve replacement (n=31). Minimally invasive parasternal approach vs. Standard sternotomy was evaluated on Hospital death. Minimally invasive parasternal aortic valve replacement had similar hospital mortality (5.9% vs 7.1%) but shorter median length of stay (5 vs 7 days) compared to standard sternotomy.
