Conduction Abnormalities Following Combined Surgical and Transcatheter Approaches for Severe Aortic Stenosis and Coronary Artery Disease
To evaluate conduction abnormalities and the requirement for permanent pacemaker implantation (PPI) in patients with complex coronary artery disease undergoing aortic valve replacement, specifically comparing clinical outcomes related to conduction disturbances between TAVR + PCI and SAVR + CABG strategies.
Key Findings:
Conduction abnormalities were prevalent in both treatment groups, with a significant incidence of PPI required post-intervention, particularly in TAVR + PCI patients.
The rates of high-grade atrioventricular block were notably high in patients undergoing TAVR + PCI, raising concerns about long-term management.
Long-term outcomes related to conduction disturbances and PPI were not well understood, necessitating further investigation.
Interpretation:
The study highlights the importance of monitoring conduction abnormalities in patients undergoing aortic valve interventions, particularly in the context of combined procedures for CAD, and underscores the need for further research.
Limitations:
Retrospective design may introduce selection bias.
Limited generalizability due to single-centre study.
Short follow-up duration for some patients may not capture long-term outcomes.
Potential confounding factors inherent in retrospective analyses.
Conclusion:
Both TAVR + PCI and SAVR + CABG are associated with conduction abnormalities and PPI, but further research is needed to clarify long-term implications.
