Combining OCT and FFR for Decision-Making in PCI: Insights from the FUSION Study

Description

Percutaneous coronary intervention (PCI) remains a cornerstone of treatment for patients with coronary artery disease, yet optimal procedural decision-making is challenged by limitations in traditional angiographic assessment. Emerging technologies such as fractional flow reserve (FFR) and optical coherence tomography (OCT) offer complementary solutions to these challenges. The FUSION study demonstrates that while angiography and OCT tend to overestimate the need for revascularization compared to FFR, OCT-guided stent selection is far superior to angiography alone, reducing discrepancies in device sizing and enhancing procedural safety.

Learning Objectives

Upon completion of this activity, participants will be able to:

Critique the limitations of angiography and justify the use of physiological indices in PCI decision-making.

Apply OCT findings to select appropriate stent diameter and length during PCI planning.

Design a procedural workflow that integrates FFR and OCT for efficient PCI decision-making.

Assess the clinical benefits and limitations of combining FFR and OCT in routine PCI practice.
