Eligibility Criteria

Inclusion

  • 1\. Patient undergoing the procedure is older than 18 years, has severe aortic valve stenosis (according to ESC guidelines) and is planned for cardiac catheterization as part of the pre-operative (SAVR) or pre-percutaneous (TAVI) work up.
  • 2\. The patient has an intermediate (50-90%) coronary lesion that requires further evaluation.
  • 3\. The patient undergoing the procedure is male, or if female, has no childbearing potential or is not pregnant.

Exclusion

  • The procedure is an emergency and/or the patient is unstable.
  • Pregnancy or lactation
  • Haemodynamically unstable patients
  • Killip class III-IV heart failure
  • Previous coronary artery by-pass in the artery being assessed
  • Contra-indications for adenosine administration: severe asthma or pre-existing type 2 AV-block
  • No significant coronary artery disease (\<50% stenosis on angiography).
  • Critical coronary artery disease deemed by the Heart Team to require immediate revascularization
  • Patients will be excluded from the SPECT study (secondary objective) if they have a left main coronary stenosis \>50%, triple vessel disease, previous myocardial infarction in the same coronary artery \& tandem lesions (separated by \>10mm) requiring independent evaluation in the same coronary artery since these factors interfere with the SPECT analysis.
