Imaging Studies for Cardiovascular System III: X-Ray01:20

Imaging Studies for Cardiovascular System III: X-Ray

426
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Cardiac Catheterization IV: Nursing Management

548
Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...

Cardiac Catheterization I: Pre-Procedure Overview

866
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...

479
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...

Imaging Studies for Cardiovascular System V: CT

206
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...

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

Area of Science:

  • Cardiology
  • Medical Physics
  • Radiation Safety

Background:

  • Cardiac catheterization via radial access poses significant ionizing radiation risks to operators.
  • Protecting medical personnel from radiation is crucial for long-term health and safety.

Purpose of the Study:

  • To evaluate the effectiveness of a patient-worn removable shield in reducing operator radiation exposure during radial cardiac catheterization.

Main Methods:

  • A pre-post study design was employed, comparing radiation doses over two one-year periods with five operators.
  • Radiation exposure was monitored using three dosimeters per operator.
  • Key metrics included Fluoroscopy Time (FT) and Dose-Area Product (DAP) per procedure.

Main Results:

  • The removable shield significantly reduced radiation dose to the operator's left bracelet (p=0.003).
  • No significant differences in radiation dose were observed for neck or chest dosimeters.
  • Fluoroscopy Time per exam remained unchanged, while Dose-Area Product per procedure slightly increased.

Conclusions:

  • A removable shield effectively lowers radiation exposure to the operator's upper limb during radial cardiac catheterization.
  • Further investigation is warranted to understand the observed increase in Dose-Area Product.
