Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Assessing physiology and fractional flow reserve in particular after PCI could represent a further step to determine whether stent implantation and stenosis removal will be effective to relieve subjective and objective signs of ischemia.
Hypothesis:
Resting gradients such as whole cycle Pd/Pa and diastolic dPR and FFR will be abnormal (below ischemic threshold) in \> 20% of cases despite optimal stent implantation and angiographic result.
The use of physiology assessment in previously intervened vessels in patients referred for persisting or recurring angina might help operators to decide upon further intervention.
