[Aspects of left ventricular function in children with chronic renal failure]

Area of Science:

• Pediatric Nephrology
• Cardiology
• Medical Imaging

Context:

• Chronic renal failure (CRF) in children presents significant health challenges.
• Cardiac complications are a major concern in pediatric CRF.
• Echocardiography is a key tool for assessing cardiac function.

Purpose:

• To identify morphological and functional cardiac changes in pediatric CRF patients.
• To evaluate the impact of hemodialysis (HD) on left ventricular (LV) systolic function.
• To compare echocardiography's sensitivity with ECG and chest X-ray for LV function assessment.

Summary:

• Echocardiography revealed cardiac abnormalities in pediatric CRF patients, including hypertrophy, cardiomyopathy, valve regurgitation, pulmonary hypertension, and pericardial effusion.
• While systolic function was mostly normal, diastolic dysfunction was observed in several cases.
• Hemodialysis sessions led to improvements in LV systolic function and reduced right ventricle dimensions.

Impact:

• Echocardiography is a sensitive method for detecting cardiac dysfunction in asymptomatic pediatric CRF patients.
• Effective chronic HD programs and antihypertensive treatments can alleviate LV dysfunction.
• Echocardiography is valuable for monitoring LV systolic function during HD sessions.
