Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the study is to compare different devices available to measure fractional flow reserve (FFR) in coronary arteries.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The decision to perform a percutaneous coronary intervention (PCI) is usually based on angiographic results alone. Angiography can be used for the visual evaluation of the inner diameter of a vessel. Visual evaluation is limited by inter-individual variability.

Fractional flow reserve provides a functional evaluation, by measuring the pressure decline caused by a vessel narrowing.

The original studies validating the use of FFR were conducted with only one device (St-Jude MedicalĀ®). Recently, new FFR devices have been commercialized but have not yet been compared.
