Prospektywne, wieloośrodkowe, randomizowane badanie kontrolowane mające na celu zbadanie wartości angiografii tomografii komputerowej tętnic wieńcowych w zrozumieniu i leczeniu wapnia wieńcowego
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.

Szczegółowy opis
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) superiority in final minimal stent area assessed by IVUS, and (2) non-inferiority in 12-month target vessel failure (cardiac death, target-vessel myocardial infarction, or ischemia-driven revascularization).
CCTA-guided strategy uses advanced calcium characterization to inform pre-procedural planning and selection of plaque modification techniques. IVUS-guided strategy follows contemporary intravascular imaging-based criteria for plaque preparation and PCI optimization.
The trial aims to determine whether leveraging non-invasive CT-based calcium assessment can enhance procedural efficiency and stent results while maintaining clinical safety comparable to IVUS-guided PCI.
