Key result
Lower median sternotomy for AVR links to ~92% scar satisfaction and similar safety versus full sternotomy.
Why the study?
To compare perioperative outcomes between minimally invasive lower median sternotomy and conventional full median sternotomy in patients undergoing isolated aortic valve replacement.
Does minimally invasive lower median sternotomy improve perioperative outcomes compared to conventional full median sternotomy in patients undergoing isolated aortic valve replacement?
Cohort (n=41)
Does minimally invasive lower median sternotomy improve perioperative outcomes compared to conventional full median sternotomy in patients undergoing isolated aortic valve replacement?
Minimally invasive lower median sternotomy is a safe and feasible alternative to full median sternotomy for isolated AVR, offering equivalent perioperative outcomes and superior cosmetic results.
LMS may support use as a less invasive AVR option with comparable early outcomes; leaves open confirmation via larger randomized trials.

Wang et al. (2026) conducted a cohort in Isolated aortic valve replacement (AVR) (n=41). Minimally invasive lower median sternotomy (LMS) vs. Conventional full median sternotomy (FMS) was evaluated on Patient satisfaction with scar appearance (p=0.001). Lower median sternotomy for isolated AVR showed similar early safety to full median sternotomy, with significantly higher patient satisfaction with scar appearance (92.0% vs 37.5%, P=0.001).
