Key result
David I valve-sparing root replacement demonstrates excellent long-term durability and survival free from prosthetic complications.
Why the study?
The original valve-sparing root replacement technique described by Dr Tirone David in 1992 remains the gold standard for aortic valve reimplantation with proven durability and survival.
The paper provides a detailed step-by-step description of the David I valve-sparing aortic root replacement technique.
David I may remain preferred for durable valve-sparing root replacement; leaves open need for modern comparative trials.
The original valve-sparing root replacement technique initially described by Dr Tirone David in 1992, also known as the David I operation, remains the gold standard for reimplantation of the aortic valve (Video 1).1 This simplest iteration of the technique stands the test of time for durability and survival for patients free from prosthetic valve–related complications.2
