Insights

Intravascular imaging (IVI) use in complex percutaneous coronary intervention (PCI) varies widely among operators, despite guideline recommendations. Standardizing IVI utilization is crucial for consistent, high-quality patient care.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Medical Imaging

Background:

  • Intravascular imaging (IVI) is recommended for complex percutaneous coronary intervention (PCI) to improve patient outcomes.
  • Real-world data on the application of IVI in complex PCI procedures are limited.

Purpose of the Study:

  • To audit the real-world utilization of IVI in a consecutive series of PCI cases.
  • To analyze IVI use based on lesion complexity and individual operator practices.

Main Methods:

  • Retrospective audit of 300 consecutive PCI cases.
  • Lesions classified as complex based on characteristics like bifurcation, calcifications, chronic total occlusion, long lesions, ostial location, and left main artery involvement.
  • Analysis of IVI use by lesion subtype and operator.

Main Results:

  • 49% of PCI cases were complex; IVI was used in 53% of complex vs. 23% of non-complex PCIs.
  • IVI use was highest for chronic total occlusions (86%) and left main disease (76%), but below 50% for bifurcations, severe calcifications, and long lesions.
  • IVI use varied significantly by operator (0%-90% for complex lesions) and declined with operator age, but increased with lesion complexity.

Conclusions:

  • Despite guidelines, IVI utilization in complex PCI shows significant operator variability.
  • Standardizing IVI use through education, protocols, and system support is essential for guideline-concordant practice.

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...

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...

Imaging Studies VII: Vascular Imaging

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
