Near-infrared spectroscopy-intravascular ultrasound to improve assessment of coronary artery disease severity in patients referred for transcatheter aortic valve implantation (The IMPACTavi registry): Design and rationale
Study context
- Population
- Patients referred for transcatheter aortic valve implantation (TAVI) with angiographic evidence of coronary artery disease (CAD)
- Planned comparison
- Near-infrared spectroscopy and intravascular ultrasound (NIRS-IVUS) positive vs NIRS-IVUS negative
- Primary endpoint
- Major adverse CV events
- Follow-up
- 24-month follow-up
Methodological detailsdesign and rationale, non-randomized, observational, multicenter, Patients receive NIRS-IVUS imaging at pre-TAVI coronary angiography and are followed up to 24 months
- Design and rationale
- Non-randomized
- Observational
- Multicenter
- Patients receive NIRS-IVUS imaging at pre-TAVI coronary angiography and are followed up to 24 months
