Validation Of Quantitative Flow Ratio (QFR) - Derived Virtual Angioplasty

Validation Of Quantitative Flow Ratio (QFR) - Derived Virtual Angioplasty

Prospective intervention study to assess the accuracy of the predicted QFR-derived virtual angioplasty compared to hyperaemic and non-hyperaemic pressure-wire derived indexes after PCI, as well as with QFR post-PCI.

Inclusion Criteria:

• Patients submitted to a coronary angiogram with at least one non-left main stable coronary stenosis with PCI indication.

Exclusion Criteria:

• Severe stenosis of the left main coronary artery.
• Patients admitted with ST-elevation myocardial infarction.
• Culprit lesions in Non-ST-Elevation Acute Coronary Syndromes (NSTEACS) patients.
• Unability to identify the culprit lesion in NSTE-ACS patients.
