Insights
Coronary artery disease (CAD) complicates transcatheter aortic valve replacement (TAVR) outcomes. While CAD presence and complexity worsen survival, angiography-guided percutaneous coronary intervention (PCI) offers no benefit, suggesting a need for new strategies.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Surgery
Background:
- Aortic stenosis and coronary artery disease (CAD) frequently coexist.
- Management of concurrent CAD in patients undergoing transcatheter aortic valve replacement (TAVR) is debated.
Purpose of the Study:
- To assess the association of CAD presence, complexity, and angiography-guided percutaneous coronary intervention (PCI) with outcomes after TAVR.
Main Methods:
- Prospective observational study of 604 patients undergoing TAVR.
- Calculation of baseline and residual SYNTAX (Synergy between PCI with Taxus and Cardiac Surgery) scores (SS).
- Multivariate analysis to evaluate the impact of CAD complexity and PCI on 5-year outcomes.
Main Results:
- CAD presence and complexity significantly correlated with worse 5-year survival and increased cardiovascular mortality.
- Noncomplex CAD (SS 1-22) independently predicted increased all-cause mortality (HR: 1.43; P=0.046).
- Complex CAD (SS >22) significantly increased cardiovascular mortality (HR: 1.84; P=0.041), while angiography-guided PCI did not improve outcomes.
Conclusions:
- CAD presence and anatomical complexity are linked to poorer 5-year outcomes in TAVR patients.
- Angiography-guided PCI did not enhance outcomes.
- Further research into physiology-guided PCI is warranted for optimal management.
Background:
Aortic stenosis and coronary artery disease (CAD) frequently coincide. However, the management of coexisting CAD in patients undergoing transcatheter aortic valve replacement (TAVR) remains controversial.
Objectives:
This study sought to determine whether the presence of CAD, its complexity, and angiography-guided percutaneous coronary intervention (PCI) are associated with outcomes after TAVR.
Methods:
All patients undergoing TAVR at a tertiary referral center between 2008 and 2020 were included in a prospective observational study. Baseline SYNTAX (Synergy between PCI with Taxus and Cardiac Surgery) score (SS) and, whenever applicable, a residual SS after PCI were calculated. A multivariate analysis was performed to determine the effect of CAD, stratified according to complexity, and PCI on 5-year outcomes.
Results:
In 604 patients, the presence of CAD and its complexity were significantly associated with worse 5-year survival (SS 0: 67.9% vs SS 1-22: 56.1% vs SS >22: 53.0%; log-rank P = 0.027) and increased cardiovascular mortality (SS 0: 15.1% vs SS 1-22: 24.0% vs SS >22: 27.8%; log-rank P = 0.024) after TAVR. Having noncomplex CAD (SS 1-22) was an independent predictor for increased all-cause mortality (HR: 1.43; P = 0.046), while complex CAD (SS >22) increased cardiovascular mortality significantly (HR: 1.84; P = 0.041). Angiography-guided PCI or completeness of revascularization was not associated with different outcomes.
Conclusions:
The presence of CAD and its anatomical complexity in patients undergoing TAVR are associated with significantly worse 5-year outcomes. However, angiography-guided PCI did not improve outcomes, highlighting the need for further research into physiology-guided PCI.
