The Implementation of Intravascular Ultrasound and Fractional Flow Reserve in the Percutaneous Treatment of Very Long Coronary Artery Lesions

November 9, 2022 updated by: Povilas Budrys, Vilnius University Hospital Santaros Klinikos
A single center, prospective, observational study to investigate the impact of intravascular ultrasound (IVUS) on the functional percutaneous coronary intervention (PCI) result (assessed with fractional flow reserve (FFR)) and one-year target vessel failure (TVF) rate after percutaneous treatment of long coronary artery lesions

Study Population

Patients with functionally significant long coronary artery lesions amenable to percutaenous coronary intervention.

Description

Inclusion Criteria:

  • Chronic coronary syndrome (stable angina; staged PCI to other lesions after acute myocardial infarction with ST segment elevation);
  • Acute coronary syndrome without ST segment elevation (unstable angina or myocardial infarction without ST segment elevation);
  • Functionally significant (FFR ≤ 0.8) lesion requiring a stent length of ≥ 30 mm and amenable for percutaneous coronary intervention.

Exclusion Criteria:

  • Patient's age ≤ 18 years;
  • Acute myocardial infarction with ST segment elevation;
  • Treatment with dual antiplatelet therapy contraindicated;
  • Survival expectancy ≤ 1 year;
  • Known allergy to sirolimus, everolimus or zotarolimus.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The proportion of patients with optimal physiology result
Time Frame: 1 day
Post PCI FFR value ≥ 0.9
1 day
The proportion of patients with optimal anatomy result
Time Frame: 1 day
If all the four following IVUS criteria met: (1) good stent apposition; (2) good stent expansion (minimal stent area (MSA) >90% of distal reference lumen area and/or MSA ≥5.5mm2); (3) plaque burden 5mm proximal and distal to the stent <50%); (4) no stent edge dissection.
1 day
The proportion of patients with optimal physiology and anatomy result
Time Frame: 1 day
Post PCI FFR value ≥ 0.9 and all four IVUS criteria met
1 day

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The rate of target vessel failure (TVF)
Time Frame: 12 months post PCI follow up
Composite endpoint (target vessel related death (TV-death), target vessel related myocardial infarction (TV-MI), ischemia driven target vessel revascularization (TV-R))
12 months post PCI follow up
