Long-term Outcome of Deferred Lesion Based on FFR

Completed
Conditions
Myocardial Ischemia
Interventions
Diagnostic Test: fractional flow reserve
Registration Number
NCT03079739
Lead Sponsor
University Hospital of Ferrara
Brief Summary

Treatment of ischemic myocardium with percutaneous coronary intervention (PCI) in addition to optimal medical therapy reduces major adverse cardiac events. However, less than half of patients have a noninvasive ischemic evaluation before revascularization. Fractional flow reserve (FFR) can determine the hemodynamic significance of a coronary lesion by measuring the distal mean coronary and aortic pressures during maximal hyperemia. Previous studies conducted principally in stable coronary artery disease (CAD) patients have demonstrated that FFR-guided revascularization improves clinical outcomes, quality of life, and cost-efficiency. However, the reliability and safety of FFR assessment in different setting than stable CAD is unclear. In addition, the majority of studies are performed with the only one device. No data are available from other clinically used devices. The HALE BOPP registry is an investigator-initiated observational study, designed to prospectively include all patients referred for coronary angiography in which at least 1 lesion was evaluated by FFR.

However, the reliability and safety of FFR assessment in different setting than stable CAD is unclear. In addition, the majority of studies are performed with the only one device. No data are available from other clinically used devices.

The HALE BOPP registry is an investigator-initiated observational study, designed to prospectively include all patients referred for coronary angiography in which at least 1 lesion was evaluated by FFR.

All centers capable of performing FFR were invited to participate and there were no predefined exclusion criteria, other than the patient's unwillingness to provide written informed consent.

The decision to perform FFR was left to the operator in each case. The study primary purpose was to evaluate, in the routine daily practice, the long-term clinical outcome of coronary lesions where the treatment was deferred based on FFR result.

An independent corelab will review all angiograms to perform quantitative coronary analysis, calculation of syntax score, residual syntax score, functional syntax score and, in ACS patients, discrimination between culprit and non culprit lesions An indipendent committee will assess and adjudicate all adverse events.
