Imaging Studies for Cardiovascular System II:Types of Echocardiography

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
Cardiac Catheterization I: Pre-Procedure Overview01:28

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...

Cardiac Catheterization III: Left Heart Catheterization

Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...

Coronary Artery Disease V: Interprofessional Care

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...

    Area of Science:

    • Cardiovascular Imaging
    • Interventional Cardiology

    Background:

    • Coronary stent visualization is challenging due to thinner struts.
    • Accurate stent expansion and positioning are crucial for optimal outcomes.
    • Stentboost Subtract offers improved visualization of deployed coronary stents.

    Observation:

    • Enhanced stent visualization (ESV) uses motion compensation and multiple non-contrast images.
    • The technique assesses stent morphology, expansion, and overlap.
    • Six cases utilizing ESV were reviewed for clinical and angiographic characteristics.

    Findings:

    • ESV facilitated identification of bifurcation stenting techniques.
    • Precise stent positioning and assessment of stent-vessel relationship were improved.
    • ESV aided in identifying stent underexpansion and was additive to intravascular ultrasound (IVUS).

    Implications:

    • ESV is a novel tool for non-invasive assessment in coronary interventions.
    • This technique complements IVUS and may reduce its necessity.
    • ESV enhances the evaluation of stent positioning, expansion, and stent-vessel interactions.
