Insights
Cardiovascular magnetic resonance (CMR) offers a new, noninvasive method for assessing diastolic heart function. This technique provides accurate, reproducible 3D evaluations, overcoming previous assessment difficulties.
Area of Science:
- Cardiovascular imaging
- Cardiac physiology
- Medical diagnostics
Background:
- Assessing diastolic heart function presents significant challenges.
- Cardiovascular magnetic resonance (CMR) is an emerging noninvasive imaging modality for cardiac function assessment.
Purpose of the Study:
- To review the literature on CMR for diastolic function analysis.
- To explore the clinical applications of CMR in evaluating diastolic dysfunction.
Main Methods:
- Extensive literature review of CMR techniques for diastolic function.
- Analysis of validated CMR applications including volumetric assessment and myocardial strain analysis.
Main Results:
- CMR enables analysis of ventricular filling, chamber volumes, and 3D myocardial strains.
- Real-time imaging and automated strain analysis enhance regional diastolic function assessment.
- Many CMR techniques are rapidly transitioning to clinical use for diastolic function evaluation.
Conclusions:
- Cardiovascular magnetic resonance (CMR) is a highly accurate and reproducible noninvasive 3D technique.
- CMR is emerging as a valuable tool for assessing diastolic function in various heart diseases.
Background:
The assessment of diastolic heart function has been hampered by multiple difficulties. Cardiovascular magnetic resonance (CMR) is a new, noninvasive technique to study cardiac function.
Methods:
The literature on CMR for the analysis of diastolic function and its clinical applications is extensively reviewed.
Results:
Analysis of ventricular filling velocity and volume flow, volumetric assessment of ventricular chamber volume, analysis of 3-dimensional myocardial strains, and assessment of myocardial energy content are numerous validated applications of CMR. With the advent of real-time imaging and automated analysis of myocardial strains, CMR tagging is a promising method to assess regional diastolic function. Today, many CMR techniques are leaving the experimental or developmental stage rapidly and becoming clinically available for the evaluation of diastolic function in heart disease.
Conclusions:
CMR is emerging as a highly accurate and reproducible noninvasive 3-dimensional technique for the assessment of diastolic function.
