Cardiac murmurs in children

Area of Science:

• Pediatric Cardiology
• Neonatal Auscultation
• Congenital Heart Disease

Background:

• Approximately 50% of children have cardiac murmurs, but less than 1% indicate congenital heart disease (CHD).
• Cardiac murmurs can be the initial clinical indicator of significant CHD in pediatric populations.
• Despite routine newborn screenings, about 50% of CHD cases may go undetected.

Purpose of the Study:

• To provide a simplified, comprehensive update on cardiac murmurs in neonates and children.
• To highlight the importance of recognizing red flags in pediatric cardiovascular assessments.
• To emphasize essential auscultatory skills for diagnosing heart murmurs and related conditions.

Main Methods:

• Review of current literature on pediatric cardiac murmurs and associated conditions.
• Emphasis on clinical skills for auscultation and physical examination.
• Discussion of syndromic associations with common CHDs.

Main Results:

• Cardiovascular signs and symptoms in neonates and children with murmurs can be variable.
• Differential diagnosis relies on murmur characteristics (systolic, diastolic, continuous) and location.
• Identification of pathological murmurs and red-flag signs necessitates prompt referral.

Conclusions:

• Accurate identification of critical murmurs requires significant clinical expertise.
• Understanding red flags and syndromic associations aids in diagnosing pediatric CHD.
• Prompt referral to pediatric cardiology is crucial for infants with concerning murmurs.
