NCT05007535
Brief Summary:
This prospective, single arm, observational cohort study is designed to assess the safety and efficacy of (high-definition) intravascular ultrasound (HD-IVUS) as guidance for primary percutaneous coronary intervention (PCI) and to assess culprit lesion plaque characteristics and thrombus morphology in patients with ST-elevation myocardial infarction (STEMI).
Objectives:
* To assess clinical outcomes after IVUS-guided primary PCI in STEMI patients.
* To assess IVUS-guided optimization in STEMI patients.
* To assess culprit lesion plaque characteristics in STEMI patients with HD-IVUS.
* To assess and quantify thrombus in STEMI patients with HD-IVUS.
* To explore HD-IVUS derived predictors for clinically relevant aspiration thrombectomy.
Detailed Description:
The SPECTRUM study is an investigator-initiated, single-center, prospective, single arm, observational cohort study investigating the safety and efficacy of (HD)-IVUS as guidance for primary PCI in 200 patients with STEMI. This study enables the assessment of culprit lesion plaque characteristics and thrombus morphology with a 40-60 MHz HD-IVUS catheter.
All study patients will have a protocolized pre-intervention IVUS pullback directly after recanalization (so before any lesion preparation, i.e. balloon dilatation, aspiration thrombectomy or stent placement) and a post-intervention IVUS pullback. Subsequently, if IVUS-guided optimization is performed, a final pullback is highly recommended and considered as the post-optimization IVUS pullback.
The primary study outcomes are target vessel failure at 12 months and incidence of IVUS-guided optimization. More information on outcome measures is provided in the section below.
