Abstract: Objective The purpose of this study was to evaluate the safety and clinical oulcomes of aortic valve replacement (AVR) performed with minimally invasive technique.Methods From June 2010 to October 2011,20 cases of minimally invasive AVR were performed.The mean age was (47.60±12.28) ;12 males and 8 females.All patients are ventilated with a double-lumen endotracheal tube,through the 3nd anterior intercostals space with a 5 -6cmskin incision,right femoral artery and vein cannulation are used to establish CPB,direct aortic cross-clamped by Chitwood sliding clamp through the right 4th intercostals space,and completed the aortic valve replacement.Results Mean length of incision was (4.73±0.54)cm.Mean duration of cardiopulmonary bypass was (124±39.83)min,crossclamp time was (97.21±33.17) min.Median intubation time was (13.55±3.87)hours.Median duration of intensive care and postoperative hospital stay was (16.34±3.82)hours and (6.63±1.45) days,respectively.Hospital mortality was 0.There was no perivalvular leakage,Conclusion Minimally invasive aortic replacement with a modified Port-Access approach is feasible,small incisions,more cosmetic,shorter length of bospital stay and less need for blood transfusion are attainable.
