Amit Agrawal, Dalwinder Janjua, Abdulrahman Ahmed Alsayed Ali Zeyada, Ahmed Taher Elsheikh
Clin Exp Pediatr. 2024;67(4):178-190.   Published online June 19, 2023
· Pediatric heart failure (PHF) is a clinical syndrome featuring various symptoms (shortness of breath, ankle swelling, fatigue) and signs (pulmonary crackles, peripheral edema).
· Congenital heart diseases are the most common underlying etiology of PHF, whereas myocarditis and primary cardio-myopathies are common in children without structural ab-normalities.
· PHF pathophysiology is complex and multifactorial and varies by etiology and age.
· PHF management includes decongestive therapy, treatment of underlying causes, preventing progression, and managing pulmonary or systemic obstructions.
· Drugs should be chosen based on pharmacodynamics, clinical manifestations, hemodynamic state, and renal function.
