How to use MRI in cardiac disease with diastolic dysfunction?

Area of Science:

• Cardiology
• Medical Imaging
• Cardiovascular Physiology

Background:

• Left ventricular diastolic dysfunction (DD) is an early, often asymptomatic stage of heart failure.
• DD can progress to heart failure with preserved or reduced ejection fraction.
• It is characterized by impaired relaxation and reduced ventricular compliance.

Purpose of the Study:

• To review cardiac magnetic resonance (CMR) imaging findings in left ventricular diastolic dysfunction (DD).
• To highlight imaging features that aid in identifying the underlying causes of DD.
• To explore how CMR can advance the assessment of diastolic function beyond traditional echocardiography.

Main Methods:

• Review of current literature and established guidelines on CMR in DD.
• Step-by-step analysis of CMR sequences and parameters relevant to diastolic function.
• Correlation of CMR findings with echocardiographic data and clinical presentation.

Main Results:

• CMR offers detailed tissue characterization and volumetric analysis beyond standard echocardiography.
• Specific CMR sequences can reveal patterns indicative of impaired relaxation and altered filling.
• CMR can differentiate causes of DD, such as infiltrative diseases or hypertensive heart disease.

Conclusions:

• Cardiac magnetic resonance (CMR) imaging is a valuable tool for comprehensively assessing left ventricular diastolic dysfunction (DD).
• CMR complements transthoracic echocardiography by providing insights into tissue properties and underlying etiologies of DD.
• Integrating CMR findings can enhance diagnostic accuracy and guide management strategies for DD.
