Brief Summary
Computed tomography (CT) has become an established tool in the diagnostic workup of patients with suspected coronary artery disease (CAD). The availability of coronary CT angiography (CCTA) before the invasive procedure allows stratifying case complexity and can be used to improve patient selection for PCI, to plan and guide therapeutic interventions. Beyond the diagnostic and therapeutic phase, it helps to better organize the catheterization laboratory workflow. The P4 study is an investigator-initiated, multicenter, randomized study with a non-inferiority design of patients with an indication for PCI aiming at comparing clinical outcomes between two imaging strategies to guide PCI, being coronary CT-guided PCI strategy (investigational technology) and IVUS-guided PCI strategy (comparator). After identifying the presence of a significant coronary stenosis, the patient will be randomized either to CT- or IVUS-guided PCI groups. Both CT and IVUS-guided PCI will be performed following the P4 trial protocol. When the procedure is completed, post-PCI FFR will be measured. All patients will be followed in hospital, at 30 days (±15 days), 12 months (±1 month) and yearly until 5 year.

Outcome Measures
Primary Outcomes (1)
rate of MACE between CCTA- and IVUS-guided PCI strategy

12 months follow-up
Secondary Outcomes (23)
Compare in-hospital resource utilization between CCTA- and IVUS-guided PCI strategies.

Study Arms (2)
CT-guided PCI strategy
EXPERIMENTALQAngio CT Research Edition is a software suite providing several functionalities for the analysis of coronary computed tomography angiography (CCTA) scans to extract and present relevant information on the coronary vasculature for further clinical investigation. Also, QAngio CT Research Edition allows to export this information for later viewing during x-ray angiography (XA) procedures to help physicians plan and guide the interventional procedure.
intravascular ultrasound (IVUS)-guided PCI strategy
ACTIVE COMPARATORIntravascular ultrasound (IVUS) is an invasive intravascular imaging technique able to visualize the coronary vessel. The use of IVUS-guided PCI has been endorsed an recommended by the European Society of Cardiology. The device is considered part of standard of clinical care.
Interventions
CT-guided PCI with standardized pre-procedural planning and online guidance.
use of IVUS during PCI procedure (standard of care)
Eligibility Criteria
You may qualify if:
- The subject must be at least 18 years of age and younger than 80 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 elective 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 ≥6 leads plus ST-segment elevation in aVR, life-threatening arrhythmias, mechanical complications of MI, resuscitated cardiac arrest, GRACE risk score\>140.
- All target lesions must be planned for treatment only in vessels with RVD ≥2.5 mm and ≤4.0 mm.
- No more than 2 target vessels are allowed. A bifurcation counts as a single lesion even if the side branch is planned to be treated.
- Subject must provide written Informed Consent before any study-related procedure.
You may not qualify if:
- Age \<18 years or ≥80 years old
- STEMI as clinical presentation.
- Uncontrolled or recurrent ventricular tachycardia.
- Hemodynamic instability.
- Severe renal dysfunction, defined as an eGFR ≤30 mL/min/1.73 m2.
- Atrial fibrillation, flutter, or arrhythmias.
- Previous PCI or CABG.
- The target lesion is in the left main coronary artery
- BMI ≥35 kg/m2.
- Insufficient CT quality assessed by the Core lab.
- Comorbidity with life expectancy ≤ 2 years.
- Inability to take DAPT (both aspirin and a P2Y12 inhibitor) for at least 12 months in the patient presenting with an ACS, or at least 6 months in the patient presenting with stable CAD, unless the patient is also taking chronic oral anticoagulation in which case a shorter duration of DAPT may be prescribed per local standard of care.
- Planned major cardiac or non-cardiac surgery within 24 months after the index procedure Note: Major surgery is any invasive operative procedure in which an extensive resection is performed, e.g., a body cavity is entered, organs are removed, or normal anatomy is altered. Note: Minor surgery is an operation on the superficial structures of the body or a manipulative procedure that does not involve a serious risk. Planned minor surgery is not excluded.
- Prior PCI within the target vessel within 12 months.
- Subject has known hypersensitivity or contraindication to any of the study drugs (including all P2Y12 inhibitors, one or more components of the study devices, including everolimus, zotarolimus, biolimus, sirolimus, cobalt, chromium, nickel, platinum, tungsten, acrylic, and fluoropolymers, or radiocontrast dye that cannot be adequately pre-medicated.
