Mini-Sternotomy Versus Conventional Sternotomy In Aortic Valve Replacement Surgery; A Comparative Study.

Abstract

To assess safety; efficacy and efficiency of mini-sternotomy in aortic valve replacement in comparison to conventional sternotomy on short term follow up. This comparative study between 45 patients having aortic valve replacement via fullsternotomy versus 45 others planned for upper j-shaped mini-sternotomy, was conducted from May 2019 to February 2022 in Kafrelsheikh university hospital, Egypt. Data was collected and statistically analysed to assess outcomes. Mini-Sternotomy approach was compared to conventional approach on the aspects of cardio pulmonary bypass (CPB) (p=0.153) and cross clamp (CC) time (p=0.673),. There was significantly less postoperative bleeding (p<0.001), rate of blood transfusion (p<0.001), duration of ICU stay (p=0.013) and total hospitalstay (p=0.022) in ministernotomy approach in comparison to conventional sternotomy. For primary isolated AVR, lessinvasive techniques are a realistic, practical, and good alternative that offers better postoperative results than Full Sternotomy.
