Study Arms (1)
Single arm
OTHERCoronary physiology measurements both pre- and post- transcatheter left-sided valvular intervention.
Interventions
1. Pd/Pa, diastolic pressure ratio (dPR), resting full cycle ratio (RFR), FFR, coronary flow reserve (CFR), and index of microvascular resistance (IMR) measurements in the coronary of interest before the valvular intervention. 2. Pd/Pa, dPR, RFR, FFR, vFFR, CFR and IMR measurements in the coronary of interest after the valvular intervention.
Eligibility Criteria
You may qualify if:
- Age ≥ 18.
- a) TAVI cohort: severe aortic valve stenosis for which TAVI is scheduled after discussion in the Heart Team.
- b) TMVr cohort: severe functional/degenerative mitral regurgitation for which TMVr is scheduled after discussion in the Heart Team.
- At least intermediate coronary artery disease, defined as 50-99% diameter stenosis in a vessel ≥ 2.5 mm
- Elective procedure
- Written informed consent
You may not qualify if:
- TAVI cohort: height coronary ostia \< 10 mm
- Severe chronic kidney disease, defined as estimated glomerular filtration rate \< 30 ml/min.
- Contra-indication for intravenous adenosine: severe asthma or chronic obstructive pulmonary disease, known allergy to adenosine or previous reported bronchospasm in response to adenosine.
- Degenerated surgical or transcatheter aortic valve bioprosthesis.
- Vessels that have collaterals to a chronic total occlusion or that are supplied by an arterial or venous bypass graft will not be interrogated in this study.
