RESUMEN
With continuous improvements in surgical techniques， medical engineering and material science， root replacement with composite valve graft （CVG） or Bentall procedure has become the standard procedure for aortic root lesions. As an alternative to the Bentall procedure， valve-sparing aortic root replacement （VSRR） avoids the complications associated with lifelong anticoagulation and mechanical valves； reduces the incidence of thromboembolic and bleeding events； and its favorable haemodynamics and potentially lower risk of endocarditis ensure durable postoperative aortic valve function and a much better quality of patient survival. This article reviews the indications for root replacement with preservation of the aortic valve， the key points of the standardized technique and its long-term results in different patients.
RESUMEN
@#Total root replacement (TRR) with a valved conduit has long been the treatment standard for most aortic root diseases. However, with advances in technology and a deeper understanding of aortic root anatomy and hemodynamics, valve-sparing aortic root replacement (VSRR) and personalised external aortic root support (PEARS) have emerged. It is especially important to choose the appropriate procedure for different aortic root diseases. When evaluating these three surgical procedures, it is necessary to focus on the treatment and prevention of the dissection and balance the short-term and long-term risks of the patients. This article outlines aortic-related diseases and the selection of surgery.
