Key result
Upper J-shaped mini-sternotomy for aortic valve replacement was associated with longer total operative time (341 vs 196.1 min, P=0.001) but shorter ICU stay and lower pain than full sternotomy.
Why the study?
Minimally invasive approaches are increasingly used for aortic valve replacement, prompting a direct comparison of outcomes between minimally invasive upper mini-sternotomy and full sternotomy.
Does upper J-shaped mini-sternotomy improve operative times and pain scores compared to full sternotomy in patients undergoing aortic valve replacement?

Upper J-shaped mini-sternotomy for aortic valve replacement reduces ICU stay and postoperative pain compared to full sternotomy, despite requiring longer operative times.
Background: Minimal invasive approaches are used more frequently for aortic valve replacement (AVR). This study aimed to compare the outcomes of both minimally invasive upper mini-sternotomy and full sternotomy for AVR. Methods: 100 patients with isolated aortic valve disease were enrolled in this prospective observational study. We grouped the patients according to the technique, group A (n=40) underwent upper J-shaped mini-sternotomy, and group B (n=60) underwent full sternotomy. Study endpoints were operative times and pain score. Results: The mean age of the patients was 46.4±10.1 years. There was no difference in preoperative data between both groups. There was a significant difference in aortic cross-clamp time (87.2± 8.6 vs. 59.2± 6.6 min in group A and B, respectively, p= 0.001), and total bypass time (115.1± 9.2 vs. 75.3± 4.3 min in group A and B, respectively, p= 0.001) between both groups. The total operative time was 341±11.7 and 196.1±18.4 min in groups A and B, respectively (p= 0.001). The ICU stay was 29.4±8.2 hours in group A and 41.2±13.3 hours in group B (p= 0.001). Patients who had mini-sternotomy had lower pain (p= 0.001) and better patient satisfaction score (p< 0.001). Conclusion: J-shaped upper mini-sternotomy is a safe and effective strategy for aortic valve replacement. The procedure may be associated with decreased pain and comparable morbidity to the conventional approach.

Ibrahim et al. (2020) conducted an observational in Isolated aortic valve disease (n=100). Upper J-shaped mini-sternotomy vs. Full sternotomy was evaluated on Operative times and pain score (p=0.001). Upper J-shaped mini-sternotomy for aortic valve replacement was associated with longer total operative time (341 vs 196.1 min, P=0.001) but shorter ICU stay and lower pain than full sternotomy.
