Imaging Studies for Cardiovascular System V: CT

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...

Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

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...

Area of Science:

Cardiovascular Medicine
Medical Imaging

Background:

Transcatheter aortic valve replacement (TAVR) is a growing alternative to surgical aortic valve replacement (SAVR) for high-risk patients with severe aortic stenosis.
TAVR has demonstrated improved survival and symptom relief in this patient group.
The PARTNER trial confirmed TAVR's superiority over medical treatment and non-inferiority to SAVR in high-risk individuals.

Purpose of the Study:

To highlight the essential role of preinterventional diagnostic workup in TAVR procedures.
To emphasize the importance of detailed aortic annulus (AA) anatomy assessment for complication avoidance.
To describe the increasing significance of computed tomography (CT) in pre-TAVR evaluations.

Main Methods:

Review of current imaging modalities used for aortic annulus (AA) sizing, including echocardiography, catheter angiography, and computed tomography (CT).
Comparison of 2D imaging techniques with CT for providing comprehensive AA anatomy and geometry information.
Evaluation of CT's role in assessing the vascular access route prior to TAVR.

Main Results:

Computed tomography (CT) provides superior and comprehensive information on aortic annulus (AA) anatomy and geometry compared to 2D imaging.
CT aids in appropriate patient selection and prosthesis sizing for TAVR.
CT is increasingly utilized for evaluating the vascular access route before TAVR procedures.

Conclusions:

Accurate assessment of aortic annulus (AA) anatomy is critical for successful TAVR and complication prevention.
Computed tomography (CT) has emerged as a key imaging modality for pre-TAVR assessment, offering detailed anatomical insights.
CT supports optimal patient selection, prosthesis sizing, and vascular access planning in TAVR.
