A safer technique of aortic root replacement after aortic valve replacement.
Aortic root replacement after aortic valve replacement (AVR) is often complicated by bleeding around the aortic root, which increases the risk of morbidity and mortality, making it a technically challenging procedure. We describe a new technique of aortic root replacement designed to minimize bleeding around the aortic root. This surgical technique focuses on safe dissection and exposure of the aortic root to avoid inadvertent entry into the right atrium or right ventricle; on modifying the proximal anastomosis of the graft to the aortic annulus; and on performing a coronary artery reimplantation that achieves complete hemostasis at the suture lines. We performed aortic root replacement after AVR in four patients over a 4-year period, without encountering any bleeding around the aortic root.
