Congestive cardiac failure (CCF) is defined as the inability of the heart to maintain an output adequate to meet the metabolic demands of the body, resulting from either systolic or diastolic dysfunction. Systolic failure occurs due to the heart’s reduced pumping efficiency, while diastolic failure arises when the heart cannot fill effectively at low pressures. The key clinical manifestations include dyspnea, hepatomegaly, and peripheral edema due to elevated left or right ventricular pressures1.
Diastolic failure can occur in conditions such as mitral or tricuspid stenosis, constrictive pericarditis, restrictive cardiomyopathy, acute ventricular overload, myocardial ischemia, hypertrophic cardiomyopathy, and dilated cardiomyopathy1
In infants, CCF is frequently linked to congenital heart defects, myocarditis, arrhythmias, Kawasaki disease, pulmonary hypertension, and metabolic conditions like hypocalcaemia or anemia. In older children, causes may include rheumatic fever, systemic hypertension, or infective endocarditis2,3.
Infants typically present with poor feeding, failure to thrive, excessive sweating, and respiratory distress. Older children may show signs similar to adults, such as fatigue, orthopnoea, and weight gain from fluid retention. Physical examination findings may include tachypnea, tachycardia, hepatomegaly, pulmonary congestion, and peripheral edema3.
Management of CCF focuses on treating the underlying etiology, optimizing preload and afterload, and enhancing myocardial contractility. Common pharmacological therapies include diuretics, ACE inhibitors, beta-blockers, and inotropes. In severe or unresponsive cases, surgical interventions such as valve repair or correction of congenital anomalies, or even mechanical ventilation, may be necessary3.

The prognosis is generally favorable, with most patients recovering over weeks to months; however, some may experience residual symptoms. Prevention strategies include prompt treatment of infections and avoiding modifiable risk factors2.
