Summary
Transcatheter aortic valve replacement (TAVR) requires a team-based imaging approach. This review guides the use of multimodality imaging for TAVR planning, implantation, and follow-up.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Severe aortic stenosis management has been revolutionized by transcatheter aortic valve replacement (TAVR).
- TAVR necessitates a comprehensive, team-based approach utilizing multiple imaging modalities throughout patient care.
Purpose of the Study:
- To provide expert opinion and evidence-based guidance on integrating multimodality imaging in TAVR.
- To serve as a single resource for imaging strategies across the TAVR continuum.
Main Methods:
- Review of current literature and expert consensus on imaging modalities for TAVR.
- Structured guidance across pre-procedural, intra-procedural, and long-term follow-up phases.
Main Results:
- Each imaging modality offers unique strengths and limitations crucial for TAVR.
- Multimodality imaging is essential for optimal pre-procedural planning, intra-procedural guidance, and post-procedural monitoring.
Conclusions:
- Effective integration of multimodality imaging enhances TAVR patient care.
- Further research is recommended to refine best practices for imaging in TAVR.

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...
01:21Imaging Studies for Cardiovascular System IV: CMRI
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...
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...
01:19Imaging Studies VII: Vascular Imaging
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
01:20Imaging Studies for Cardiovascular System II:Types of Echocardiography
Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...

01:22Mitral Valve Prolapse II: Assessment and Management
IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular tachycardia.
