Intravascular Ultrasound Prediction of Myocardial Size and Coronary Computed Tomography-Derived Ischemic Burden for Coronary Lesion (IVUS-CAMS)

April 6, 2025 updated by: Young-Hak Kim, MD, PhD, Asan Medical Center
The aims of this study are 1) to identify IVUS determinants of the CAMS-derived myocardial territories subtended to the diseased vessels, 2) to find IVUS determinant for the extent of CAMS-derived myocardial size, and 3) to develop the mathematical model that integrates the IVUS information about myocardial territory and stenosis severity and predicts the extent of CAMS-derived myocardial size.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

20 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

patients who undergo coronary computed tomography angiography, invasive coronary angiography and IVUS assessment prior to intervention will be enrolled. The patients should have at least one coronary artery lesion (including non-left main and isolated left main disease) with visually estimated diameter stenosis >50%

Description

Inclusion Criteria:

  • Age 20years or older
  • Patients who have at least one epicardial coronary artery lesion (including isolated left main disease or side branch) with visually estimated diameter stenosis >50% and take coronary angiography, CT angiography and IVUS
  • Willing and able to provide informed written consent

Exclusion Criteria:

  • In-stent restenosis
  • Bypass graft
  • Suspected coronary spasm even after sufficient nitrate injected
  • Cases in which the IVUS imaging catheter failed to cross the lesion
  • Poor quality IVUS or CT images
  • Visible collateral flow on angiography
