Evaluating FFR Guided PCI in Coronary Tandem Lesions

A Multicenter, Prospective Cohort to Evaluate the Effect of FFR Guided Percutaneous Coronary Intervention in Coronary Tandem Lesions

Observational Asan Medical Center · NCT02797561

This study is testing if using a special measurement called FFR to guide heart artery procedures helps people with multiple blockages feel better and have better results than the usual methods.

What this trial studies

This study aims to assess the impact of using fractional flow reserve (FFR) to guide percutaneous coronary intervention (PCI) in patients with tandem lesions in their coronary arteries. It involves a five-year follow-up to monitor outcomes and effectiveness. The study will include patients who have undergone FFR evaluation of their tandem lesions and have provided written consent. The goal is to determine if FFR guidance improves patient outcomes compared to standard practices.

Who should consider this trial

Good fit: Ideal candidates are patients with tandem coronary lesions who have been evaluated using FFR.

Not a fit: Patients with severe coronary conditions, such as TIMI flow less than 3 or severe calcification, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved treatment outcomes for patients with complex coronary artery disease.

How similar studies have performed: Other studies have shown promising results with FFR-guided interventions, indicating potential for success in this approach.
