A Prospective, Multicenter, Randomized Controlled Trial to Investigate the Value of Coronary CT Angiography in the Understanding and Management of Coronary Calcium
Fundación EPIC
Summary
The OPTIMAL randomized clinical trial has been designed to compare two imaging strategies and to test the hypothesis that a calcium modification strategy informed by coronary CT angiography (CCTA) will improve procedural efficiency and effectiveness compared with the current standard of care (IVUS-guided PCI) while achieving similar clinical outcomes in patients with hemodynamically significant calcified coronary artery disease.
Description
The OPTIMAL Trial is a prospective, multicenter, randomized controlled study evaluating whether a coronary CT angiography (CCTA)-guided calcium modification strategy can improve the treatment of patients with hemodynamically significant, calcified coronary artery disease undergoing percutaneous coronary intervention (PCI). Seven hundred patients with flow-limiting stenosis (FFRCT ≤0.80) and moderate-to-severe calcification on CCTA will be randomized 1:1 to either CCTA-guided or intravascular ultrasound (IVUS)-guided calcium modification. The study includes two co-primary endpoints: (1) superi…
