Objectives: After studying the article titled “Diastolic Dysfunction and the New Recommendations for Echocardiographic Assessment of Left Ventricular Diastolic Function: Summary of Guidelines and Novelties in Diagnosis and Grading,” you will be able to:
Explain the four phases of diastole
Evaluate the 2009 and 2016 recommendations for evaluation of left ventricular (LV) diastolic function by echocardiography
Understand the importance of assessing LV diastolic function
What is the approximate percentage of mild left ventricular diastolic dysfunction (LVDD) in the general population? 7% 32% 47% 21%
Phase 2 of diastole consists of: Slow filling diastasis Active filling (A wave) Rapid passive filling (E wave) Isovolumic relaxation
Which grade of DD is characterized by restrictive filling with elevated filling pressure and noncompliant LV? 0 1 2 3
Which of the following conditions is associated with a disappearance of the A wave? Atrial fibrillation Atrioventricular block Atrial septal defect Cardiomyopathy
What value is considered normal for propagation velocity (Vp)? >25 cm/s >55 cm/s >45 cm/s >35 cm/s
According to DD2009, what value is considered normal for ejection fraction? ≥20% ≥30% ≥40% ≥50%
According to DD2016, how many minimal abnormal parameters are required to diagnose DD? 1 2 3 4
