Imaging Studies for Cardiovascular System V: CT01:28

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Summary
This summary is machine-generated.

Intravascular imaging (IVI) use for percutaneous coronary intervention (PCI) is rising in VA hospitals, yet shows significant variation. IVI demonstrates reliability as a performance measure, but its impact on patient outcomes requires further study.

Area of Science:

  • Cardiovascular Medicine
  • Medical Imaging
  • Health Services Research

Background:

  • Intravascular imaging (IVI) improves percutaneous coronary intervention (PCI) outcomes but remains underutilized.
  • Current quality metrics do not consistently incorporate IVI, hindering its widespread adoption.

Purpose of the Study:

  • To analyze temporal trends in IVI utilization for PCI within Veterans Affairs (VA) hospitals.
  • To assess factors influencing IVI use and its reliability as a performance measure.
  • To evaluate the association of IVI use with clinical outcomes post-PCI.

Main Methods:

  • Retrospective analysis of 136,071 PCIs from VA hospitals (2010-2022).
  • Contemporary cohort (2020-2022) examined for IVI use predictors and performance measure reliability.
  • Statistical models assessed variability sources (hospital, physician, patient) and 1-year clinical outcomes.

Main Results:

  • IVI use increased from 12.3% to 43.1% between 2010 and 2022.
  • Variability in IVI use was mainly attributed to hospital (54%) and physician (33%) factors.
  • IVI demonstrated high reliability (>0.96) as a hospital/physician performance measure, but no significant outcome benefit was observed.

Conclusions:

  • IVI use in VA PCI is increasing but highly variable across providers.
  • IVI meets criteria for a performance measure and should be tracked to promote adoption.
  • Further training and quality improvement initiatives are needed to optimize IVI benefits.
