Title : Assessment of Diastolic Function in Children: The dilemma and potential solution
Abstract: Left ventricular(LV) is characterized by LV relaxation, early diastolic recoil, and myocardial stiffness.LV diastolic dysfunction usually results from impaired LV relaxation with or without reduced restoring forces (and early diastolic suction) and increased LV chamber stiffness resulting in increased cardiac filling pressure. The abnormal diastolic function has been recognized in many cardiovascular diseases and is associated with worse outcomes, including total mortality and hospitalizations due to heart failure. Therefore, accurate assessment of LV diastolic function is crucial as it determines symptoms and predicts outcomes in patients with cardiovascular disease. Unfortunately, despite the multitude of available indices, assessment of diastolic dysfunction remains a challenging area in pediatric cardiology. Studies on the interpretation of left ventricular diastolic dysfunction in children with cardiomyopathy found that adult ASE/EACVI criteria may not be applicable in detecting abnormal diastolic function in the pediatric population. Current advancements in echocardiographic techniques have provided more significant insights on diastolic function assessment beyond traditional measures. This presentation will discuss the dilemma in evaluating diastolic function in children and the potential solution.
