Table 2: Summary of studies evaluating the impact of post-PCI residual SYNTAX score on TAVR outcomes.
| Study | Design | Patients with low and high rSS (n) | rSS cut-off | Clinical outcomes |
|---|---|---|---|---|
| Stefanini et al. 201414 | Single-centre registry | Low rSS = 192 High rSS = 95 |
14 | High rSS is associated with increased risk of 1-year MACCE after TAVR |
| Khawaja et al. 201510 | Single-centre registry | Low rSS = 40 High rSS = 53 |
9 | High rSS is associated with increased 1-year MACCE after TAVR |
| Paradis et al. 201712 | Single-centre registry | Low rSS = 17 High rSS = 37 |
8 | High rSS is not associated with increased 1-year MACCE after TAVR |
| Shamekhi et al. 201713 | Single-centre registry | Low rSS = 140 High rSS = 205 |
3 | High rSS is associated with increased 3-year mortality after TAVR |
| Witberg et al. 201730 | Multi-centre registry | Low rSS = 331 High rSS = 122 |
8 | High rSS is associated with increased 5-year mortality after TAVR |
MACCE = major adverse cardiovascular and cerebrovascular events; PCI = percutaneous coronary intervention; rSS = residual SYNTAX score; TAVR = transcatheter aortic valve replacement.
