Reoperative minimal access aortic valve replacement (AVR) is performed through an upper hemisternotomy with peripheral cannulation. This approach limits dissection of mediastinum and especially the left internal mammary artery (LIMA) graft in patients with previous coronary artery bypass grafting (CABG) thus minimizing trauma to the patient. This approach is safe and feasible and may have some benefit over conventional full sternotomy in terms of mortality and morbidity.
再次手术的微创主动脉瓣置换术(AVR)通过上半胸骨切开术和外周插管进行。这种方法限制了纵隔的分离,特别是对于既往有冠状动脉旁路移植术(CABG)的患者,可减少对左乳内动脉(LIMA)移植物的分离,从而将对患者的创伤降至最低。这种方法安全可行,在死亡率和发病率方面可能比传统的全胸骨切开术更具优势。
