Insights

Computed tomography (CT) is crucial for planning transcatheter valve interventions (THV), especially for mitral and aortic valves. Further development is needed for pulmonic and tricuspid valve assessments using CT imaging.

Area of Science:

  • Cardiovascular Imaging
  • Interventional Cardiology
  • Medical Technology

Background:

  • Transcatheter valve interventions (THV) are rapidly advancing.
  • Accurate pre-procedural assessment is vital for THV success.
  • Computed tomography (CT) offers detailed anatomical insights.

Purpose of the Study:

  • To define the current role of CT in THV.
  • To review the utility of CT for specific valve interventions.
  • To identify areas for future CT development in THV.

Main Methods:

  • Review of current literature and clinical practices.
  • Analysis of CT-derived measurements and their correlation with outcomes.
  • Evaluation of CT's application in aortic, mitral, pulmonic, and tricuspid valve interventions.

Main Results:

  • CT is a reliable tool for risk assessment and planning in aortic and mitral THV.
  • Empirical CT measurements are increasingly linked to clinical outcomes.
  • CT assessment for pulmonic and tricuspid valves is emerging but requires further research.

Conclusions:

  • CT plays a significant role in current transcatheter valve interventions.
  • Standardization and further research are needed to optimize CT's use in all valve THV.
  • CT is essential for the continued evolution of minimally invasive cardiac procedures.

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 for Cardiovascular System III: X-Ray

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...

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...
