Key result
Partial upper median sternotomy for AVR links to longer operating times but similar outcomes versus conventional sternotomy.
Why the study?
The theoretical advantages of mini-invasive cardiac surgery including partial upper median sternotomy for aortic valve replacement needed comparison with conventional median sternotomy.
Does partial upper median sternotomy improve perioperative outcomes compared to conventional median sternotomy in patients undergoing isolated aortic valve replacement?

Should not alter surgical approach for isolated AVR; leaves open whether minimally invasive techniques improve outcomes in randomized settings.

Does partial upper median sternotomy improve perioperative outcomes compared to conventional median sternotomy in patients undergoing isolated aortic valve replacement?
p-value: p=<0.001
Partial upper median sternotomy for aortic valve replacement increases operating times without improving clinical outcomes compared to conventional sternotomy, offering only cosmetic benefits.
Masiello et al. (2002) conducted a cohort in Isolated aortic valve replacement (n=200). Partial upper median sternotomy vs. Conventional median sternotomy was evaluated on Operating times (p=<0.001). Partial upper median sternotomy for aortic valve replacement significantly increased operating times (p<0.001) but yielded similar clinical outcomes compared to conventional median sternotomy.
