Mini-sternotomy versuMini-sternotomy versuss conventional sternotomy in aortic valve replacement surgery; A comparative study

Résumé

Objectives: To assess safety; efficacy and efficiency of mini-sternotomy in aortic valve replacement in comparison to conventional sternotomy on short term follow up. Method: 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. RESULTS: 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. CONCLUSIONS: For primary isolated AVR, lessinvasive techniques are a realistic, practical, and good alternative that offers better postoperative results than Full Sternotomy.
