Summary
Aortic valve calcification (AVC) affects 28.9% of patients over 60. AVC prevalence and severity are higher in men and older individuals, but AVC is independent of coronary artery calcification.
Area of Science:
- Cardiology
- Radiology
- Geriatrics
Background:
- Aortic valve calcification (AVC) is a primary cause of aortic stenosis.
- Understanding the prevalence and correlations of AVC with other vascular calcifications is crucial for patient management.
Purpose of the Study:
- To determine the prevalence of AVC, coronary artery calcification (CAC), and ascending aorta calcification (AAC) in patients aged 60 and over.
- To evaluate the correlation between AVC, CAC, and AAC.
Main Methods:
- Coronary computed tomography was performed on 499 patients aged 60+ presenting with chest pain.
- Evaluated coronary artery calcium score (CAC), AVC, and ascending aorta calcifications (AAC).
Main Results:
- AVC was present in 28.9% of patients. CAC (73.8%) and AAC (54.0%) were more prevalent than AVC.
- AVC, CAC, and AAC prevalence and severity were higher in patients over 70 and in men compared to women.
- No significant correlation was found between AVC and CAC or AAC, but AAC and CAC were significantly correlated.
Conclusions:
- Degenerative aortic valve calcification may be an independent process from atheromatous disease in the coronary arteries and aorta.
- Despite shared risk factors, AVC appears distinct from coronary and aortic atherosclerosis.

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...

884
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

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...

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...

Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

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...
