Left ventricular diastolic function in atrial fibrillation: Methodological implications and clinical considerations

Area of Science:

• Cardiology
• Echocardiography
• Diastology

Background:

• Left ventricular diastolic dysfunction (LVDD) assessment is vital due to its correlation with cardiac disease progression and prognostic value.
• Echocardiographic parameters for LV diastolic function generally align with invasive measurements, the current gold standard.
• No single echocardiographic parameter can fully assess LVDD.

Purpose of the Study:

• To review various echocardiographic methods for estimating LV diastolic function.
• To address the challenges of assessing LV diastolic function in patients with atrial fibrillation.
• To highlight the importance of LVDD assessment for complete clinical evaluation.

Main Methods:

• Analysis of established echocardiographic parameters for LV diastolic function.
• Evaluation of methods not dependent on atrial systole for use in atrial fibrillation.
• Exploration of novel echocardiographic techniques for diastolic function assessment.

Main Results:

• The E/A ratio, a common parameter, is often infeasible for LV diastolic function assessment in atrial fibrillation.
• Methods independent of atrial systole are necessary for accurate evaluation in this patient group.
• Novel techniques show promise but require further validation for clinical practice.

Conclusions:

• Comprehensive echocardiographic assessment of LV diastolic function is mandatory for patients, particularly those with atrial fibrillation.
• Despite challenges, LVDD evaluation remains essential for complete clinical assessment and patient management.
• Continued research into novel echocardiographic methods is needed to improve LVDD assessment accuracy.
