Abstract
Background& objectives: Minimally invasive aortic valve surgery has evolved into a well-tolerated, efficient surgical treatment option in experienced centers, providing greater patient satisfaction and lower complication rates. Potential advantages of minimally invasive aortic valve replacement (MIAVR) arise from the concept that patient morbidity and potential mortality could be reduced without compromising the excellent results of the conventional procedure which include improved cosmetic results, safer access in the case of re-operation, less post-operative bleeding, fewer blood transfusions as well as the absence of sternal wound infection. Reduced pain and hospital length of stay, decreased time until return to full activity, and decreased blood product use have also been demonstrated. Methodology: Sixty patients with aortic valve disease randomized into two equal groups; group 2A3 underwent aortic valve surgery through a minimally invasive right mini-thoracotomy. group 2B3 underwent aortic valve surgery through a full median sternotomy. The pre-operative, operative and post-operative data are compared in both groups. Results: There was no statistical difference between both groups as regard pre-operative data. There was no operative mortality in both groups but few post-operative complications occurred in both groups. Total hospital stay, ICU stay, post-operative bleeding, inotropic requirement, ventilatory support, blood transfusion was less in group 2A3, with better cosmetic appearance, while total operation time ,bypass time , cross clamp time and cost effectiveness were more in group 2A3 Conclusions: right mini-thoracotomy approach provides excellent exposure of the aortic valve, offers a better cosmetic scar and safe as full median sternotomy
