Key result
AV delay optimization in ventricularly paced adults with CHD identifies a shorter ~100 ms optimal setting.
Why the study?
AV delay optimization to improve diastolic filling and cardiac output in ventricularly paced patients is virtually unstudied in complex congenital heart disease.
Does AV delay optimization improve diastolic filling time and velocity time integrals compared to nominal settings in ventricularly paced adults with congenital heart disease?
Observational (n=9)
Does AV delay optimization improve diastolic filling time and velocity time integrals compared to nominal settings in ventricularly paced adults with congenital heart disease?
Absolute Event Rate: 100% vs 150%
In ventricularly paced adults with congenital heart disease, optimal AV delay is typically shorter than nominal settings and improves diastolic filling and cardiac output parameters.

May support individualized shorter AV delays in paced ACHD; hypothesis-generating for outcome trials.
Moore et al. (2021) conducted an observational in Congenital heart disease with ventricular pacing (n=9). AV delay optimization vs. Nominal AV delay setting was evaluated on Optimal AV delay. AV delay optimization in ventricularly paced adults with congenital heart disease yielded a median optimal AV delay of 100 ± 20 ms, which was shorter than the nominal setting of 150 ± 20 ms.
