Precise Procedural and PCI Plan (P4)
Precise Procedural and PCI Plan (P4) Randomized Clinical Trial Integration of Coronary Computed Tomography Angiography in the Catheterization Laboratory to Plan and Guide Coronary Percutaneous Procedures
Source: ClinicalTrials.gov · Last updated 21 Jan 2026
Brief summary (registry, in English)
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.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Previous PCI or CABG.
- 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.
- Prior PCI within the target vessel within 12 months.
- The subject has received a solid organ transplant that is functioning or is active on a waiting list for any solid organ transplants with expected transplantation within 24 months.
- The subject has previously received or is scheduled to receive radiotherapy to a coronary artery (vascular brachytherapy) or the chest/mediastinum.
- The subject has a history of bleeding diathesis or coagulopathy or has had a significant gastro-intestinal or significant urinary bleed within the past six months. The subject has had a cerebrovascular accident or transient ischemic neurological attack (TIA) within the past six months, or any prior intracranial bleed, or any permanent neurologic defect, or any known intracranial pathology (e.g., aneurysm, arteriovenous malformation, etc. The subject has a life expectancy \<2 years for any non-cardiac cause.
- Subject is currently participating in another investigational drug or device clinical study.
- Pregnant or nursing subjects and those who plan pregnancy in the period up to 2 years following index procedure. Female subjects of child-bearing potential must have a negative pregnancy test done within 7 days prior to the index procedure per site standard test.
Other illness
- Atrial fibrillation, flutter, or arrhythmias.
- 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.
- 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.
- The subject receives immunosuppressant therapy or has known immunosuppressive or severe autoimmune disease that requires chronic immunosuppressive therapy (e.g., human immunodeficiency virus, systemic lupus erythematosus, etc.). Note: corticosteroids are not included as immunosuppressant therapy.
- The subject has a documented or suspected hepatic disorder as defined as cirrhosis or Child-Pugh ≥ Class B.
- Presence of other anatomic or comorbid conditions, or other medical, social, or psychological conditions that, in the investigator's opinion, could limit the subject's ability to participate in the clinical investigation or to comply with follow-up requirements, or impact the scientific soundness of the clinical investigation results.
Lab values
- Severe renal dysfunction, defined as an eGFR ≤30 mL/min/1.73 m2.
- Subject has a platelet count \<100,000 cells/mm3 or \>700,000 cells/mm3.
Age
- Age \<18 years or ≥80 years old
- Comorbidity with life expectancy ≤ 2 years.
Other
- STEMI as clinical presentation.
- Uncontrolled or recurrent ventricular tachycardia.
- Hemodynamic instability.
- The target lesion is in the left main coronary artery
- BMI ≥35 kg/m2.
- Insufficient CT quality assessed by the Core lab.
- Unable to provide written informed consent (IC).
Who the study is looking for
- 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.
