Summary
Coronary artery calcification (CAC) involves active biological processes and forms calcified nodules. Advanced intravascular imaging guides percutaneous coronary intervention (PCI) strategies for better patient outcomes.
Area of Science:
- Cardiovascular Medicine and Interventional Cardiology
- Vascular Biology and Atherosclerosis Research
- Medical Imaging and Technology
Background:
- Coronary artery calcification (CAC) is a key indicator of advanced atherosclerosis and procedural complexity in percutaneous coronary intervention (PCI).
- CAC is now understood as an active biological process involving inflammation, oxidative stress, and cellular differentiation, not merely passive degeneration.
- Calcified nodules are an advanced plaque phenotype associated with significant clinical complications, including thrombosis and stent failure.
Purpose of the Study:
- To review the biological and biomechanical mechanisms underlying coronary calcification and calcified nodule formation.
- To compare multimodality intravascular imaging criteria for characterizing calcified nodules.
- To discuss contemporary imaging-guided PCI strategies for managing calcified lesions.
Main Methods:
- A structured literature search of major scientific databases (PubMed/MEDLINE, Web of Science, Scopus) was conducted.
- Inclusion criteria focused on publications from 2020-2026, yielding 83 relevant articles for narrative synthesis.
- The review synthesizes information on pathobiology, intravascular imaging, and interventional strategies.
Main Results:
- Identified diverse mechanisms driving CAC, leading to various calcific phenotypes, including problematic calcified nodules.
- Detailed criteria for characterizing calcified nodules using intravascular ultrasound (IVUS), optical coherence tomography (OCT), and hybrid imaging.
- Summarized advanced PCI techniques like atherectomy and intravascular lithotripsy for modifying complex calcified lesions.
Conclusions:
- Integrating pathobiology, imaging, and lesion-specific PCI strategies offers a clinical framework for managing calcified nodules.
- Standardized imaging definitions and validated treatment algorithms are needed for optimal patient care.
- Future research should focus on AI-assisted plaque characterization and prospective treatment validation.

01:25Imaging 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...
01:28Imaging 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...
01:26Coronary Artery Disease II: Pathophysiology
Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...
01:30Acute Coronary Syndrome III: Diagnostic Studies
Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
01:20Imaging 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...

01:28Cardiac 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...
