Background and 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. Methodology: Fifty patients with aortic valve disease randomized into two equal groups; group 2A3 underwent aortic valve surgery through a minimally invasive limited upper ministernotomy. Group 2B3 underwent aortic valve surgery through a right anterior minithoracotomy. Femoral and internal jugular venous with aortic cannulation was adopted with antegrade blood cardioplegia. Resluts: There was no statistical difference between the two groups preoperatively. There was no operative mortality in both groups but few postoperative complications occurred in both groups. Total hospital stay, ICU stay, postoperative bleeding, inotropic requirement, ventilatory support, blood transfusion was similar in both groups, as well as cosmetic appearance and cost effectiveness
