Impact of aortic valve function and the need for aortic valve repair on long- term outcomes of valve-sparing aortic root replacement: 13-year experience of David operation
Heart, Lung, and Circulation Nov 26, 2020
Cardoso LF, Dias RR, Dinato FJ, et al. - Researchers investigated results following valve-sparing aortic root replacement (VSARR) and compared if preoperative moderate or severe aortic regurgitation (AR) and or the requirement for aortic valve repair (AVR) during this procedure impacted survival as well as freedom from reoperation rates. A total of 104 patients received VSARR using the reimplantation technique from September 2005 to June 2018: 64% had preoperative moderate or severe AR, concomitant AVR was conducted in 43.3%, Marfan syndrome was present in 16.3%, and a bicuspid aortic valve was present in 12.5%. Findings revealed that performing VSARR was associated with low death rates and reasonable durability of the aortic valve. Survival and freedom from reoperation were not impacted by moderate or severe AR or by requirement for aortic valve repair during the procedure.
