In infants, feeding difficulties can signal congenital heart disease; what is the best initial clinical approach?

• A. Murmur is always present
• B. Feeding difficulties indicate only nutritional issues
• C. Consider cardiac causes and look for a murmur
• D. Immediately pursue surgery for murmur

Answer: (C)

Feeding difficulties in infants can reveal underlying congenital heart disease because the heart must work harder to meet the increased metabolic demands during feeds, and problems with cardiac output or pulmonary circulation often become evident with poor intake, fatigue, or rapid breathing.

The best initial approach is to include a cardiac assessment early. Carefully examine for signs of heart disease and auscultate to listen for a murmur. Finding a murmur can strongly point to a structural defect and should lead to prompt echocardiography and referral for further management. However, a normal auscultation does not completely rule out CHD, so persistent feeding issues or other concerning signs still warrant cardiac evaluation. Immediate surgery isn’t the first step; diagnosis and appropriate medical or surgical planning follow imaging and specialist input.
