Use case sheets
Four settings where wire-free physiology changes the decision. Each sheet sets out the clinical question, the Coroview workflow, and how to read the outputs.
Obstructive disease
Intermediate stenosis, no wire available
The clinical question
Is this 40–70% lesion flow-limiting? Wire-based FFR is often deferred for time, cost or vessel access reasons, leaving the decision to visual estimation.
Coroview workflow
Run standard diagnostic projections. Coroview reconstructs the vessel in 3D and computes FFR along its full length, with no wire and no hyperaemic agent.
Reading the output
A per-lesion pullback curve and distal 3D-FFR value for each vessel, available within seconds so treatment can be planned in the same sitting.
ANOCA / INOCA
Angina with unobstructed coronary arteries
The clinical question
The angiogram is unobstructed but symptoms persist. Without thermodilution, microvascular dysfunction goes unmeasured and patients leave without a mechanism.
Coroview workflow
Virtual IMR is derived from angiographic flow metrics and proximal aortic pressure on the same diagnostic run, alongside 3D-FFR confirming non-obstructive epicardial disease.
Reading the output
A virtual IMR value indicating whether microvascular resistance is raised, supporting an endotype-guided approach to therapy and follow-up.
MINOCA
Myocardial infarction without obstructive disease
The clinical question
Acute presentations with non-obstructive arteries need mechanism, but invasive physiology is frequently impractical in the acute setting.
Coroview workflow
Wire-free analysis of the acute diagnostic angiogram characterises both epicardial flow and microvascular resistance without extra instrumentation or lab time.
Reading the output
Combined 3D-FFR and virtual IMR profile of both coronary systems, informing mechanism-based management and onward investigation.
STEMI prognostication
Risk stratification after reperfused ST-elevation MI
The clinical question
After successful reperfusion, which patients remain at elevated risk? Microvascular injury drives adverse outcomes but is rarely measured in the acute setting.
Coroview workflow
Virtual IMR is computed from the post-reperfusion angiogram, requiring no additional wire, adenosine or lab time in an already time-critical procedure.
Reading the output
Patients are stratified by degree of virtual IMR elevation, identifying those with severe microvascular injury who are at higher risk of adverse outcomes and may warrant closer follow-up.
