Insights
Diastolic dysfunction, not always systolic, causes heart failure. Cardiac MRI effectively assesses diastolic function, complementing echocardiography for comprehensive heart failure diagnosis.
Area of Science:
- Cardiology
- Medical Imaging
Context:
- Heart failure can stem from diastolic dysfunction, impacting left ventricular filling and stroke volume.
- Transthoracic echocardiography is the standard non-invasive method for assessing diastolic function.
Purpose:
- To evaluate the utility of cardiac Magnetic Resonance (MR) imaging in assessing diastolic function.
- To compare cardiac MR findings with echocardiography for diastolic function analysis.
Summary:
- Cardiac MRI, utilizing flow sequences, demonstrates strong agreement with echocardiography in evaluating diastolic function.
- MRI provides a practical method for analyzing diastolic function by assessing flow dynamics through the mitral valve and pulmonary veins.
Impact:
- Cardiac MRI analysis of diastolic function should be integrated into routine cardiac examinations.
- This integration can enhance the diagnostic capabilities for heart failure with preserved ejection fraction.
Abstract:
Heart failure is not always due to an alteration in systolic function, and a diastolic dysfunction could explain many cases of heart failure with a normal systolic function. Diastolic function depends on the left ventricular filling capacity to ensure a normal stroke volume. It is routinely measured with transthoracic echocardiography, as it is an easily accessible non-invasive test. The MRI, using flow sequences, shows good agreement with the echocardiography, analysing the diastolic function in a practical way, by the flow into the mitral valve and pulmonary veins. In this sense, the analysis of diastolic function should be added as part of a routine cardiac MR examination.
