Observational analysis shows improved hemodynamic parameters in systolic heart failure patients, highlighting the potential of AV optimization.

AV optimization significantly increased mitral inflow VTI and aortic valve VTI (p<0.001).
Heart rate decreased significantly compared to pre-optimization values (p=0.003).
No changes in AV delay time post-optimization were observed (p=0.685).
Further studies are needed to understand long-term impacts and individual responses to AV optimization.

Pektaş et al. (2025) studied this question.
