Key result
David I procedure matches Bentall safety with zero mortality despite longer cross-clamp times.
Why the study?
The safety and efficiency of David I procedure compared with Bentall procedure in aortic root disease required evaluation.
Does the David I procedure improve safety and efficiency compared to the Bentall procedure in patients with aortic root disease?
Cohort (n=46)
Does the David I procedure improve safety and efficiency compared to the Bentall procedure in patients with aortic root disease?
Absolute Event Rate: 0% vs 0%
The David I procedure is as safe and effective as the Bentall procedure in the peri-operative period for aortic root disease, despite requiring a longer cross-clamp time.
David I shows perioperative safety comparable to Bentall despite longer clamp times; leaves open need for randomized trials on long-term outcomes.
Objective To evaluate the safety and efficiency in aortic root disease. Methods From April 2017 to April 2018, 46 cases of aortic root disease accepted DavidⅠ[20 cases, 15 males and 5 females, aged(39.6±15.8)years, aortic root diameter was(58.3±4.4)mm] or Bentall[26 cases, 22 males and 4 females, aged(50.8±12.6)years, aortic root diameter was(59.5±5.0)mm], the data in the peri-operation and heart function in recent period after operation. Results No mortality was observed in the study. Morbidity occurred in both group was comparable. Mean cross-clamp time(129.5±28.6)min vs.(94.3±35.3)min(P 0.05). ICU staying time(1.0±0.2)day vs.(1.1±0.3)day(P>0.05). At the latest visit(10.5±6.8)months in David Ⅰ, no obviously regurgitation of aortic valve were observed 0.75±0.44 vs 1.0±1.3(P>0.05). Conclusion Except for the prolonged cross-clamp time, David Ⅰ is safely and effective in aortic root disease compared with Bentall in peri-operative period . The long term results need further follow-up .

Zhou et al. (2019) conducted a cohort in Aortic root disease (n=46). David I procedure vs. Bentall procedure was evaluated on Mortality. The David I procedure was safe compared to the Bentall procedure for aortic root disease, with 0% mortality in both groups but a longer mean cross-clamp time (129.5 vs 94.3 min).
