What this trial studies

This registry aims to evaluate the feasibility and diagnostic performance of Quantitative Flow Ratio (QFR) analysis conducted by inexperienced medical users in a real-world setting, using Fractional Flow Reserve (FFR) as the gold standard. The study will include patients over 18 years old who undergo clinically indicated FFR procedures at the Institute for Cardiovascular Diseases 'Dedinje'. The focus is on understanding how well QFR can be performed outside of specialized core labs, particularly by those with limited experience. The findings could provide insights into the reliability of QFR in everyday clinical practice.

Why it matters

Potential benefit: If successful, this study could enhance the diagnostic accuracy of coronary artery disease assessments in clinical settings.

How similar studies have gone: Previous studies have shown promising results for QFR analysis, but this registry focuses on its application by inexperienced users, making it a novel approach.
