About This Trial

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.

Who Can Join?

Inclusion Criteria: * The subject must be at least 18 years of age and younger than 85 years old * Subject must have evidence of myocardial ischemia (e.g., stable angina, silent ischemia (ischemia in the absence of chest pain or other anginal equivalents), unstable angina, or acute myocardial infarction) suitable for PCI. Patients with a clinical indication for revascularization presenting with stable coronary artery disease or stabilized acute coronary syndrome defined as follows unstable angina (Braunwald class IB, IC, IIB, IIC, IIIB, IIIC), patients with NSTEMI without high-risk features such as recurrence of chest pain, ST-segment depression>1mm in โ‰ฅ6 leads plus STsegment elevation in aVR, life-threatening arrhythmias, mechanical complications of MI, resuscitated cardiac arrest, GRACE risk score>140. * All target vessels must have reference vessel diameter (visually assessed by CCTA) โ‰ฅ 2.5 mm * Subject must provide written informed consent before any study-related procedure Exclusion Criteria: * STEMI as the…
