INTRODUCTION

Heart murmurs are common in infants and children. Evaluation of a murmur is the most common reason for referral to a pediatric cardiologist [1,2]. While the reported prevalence of congenital heart disease is approximately one percent, a majority of children have innocent murmurs at some time [3,4]. Being able to distinguish a murmur associated with heart disease from a benign etiology is important for diagnosis and management (table 1).

Common causes of heart murmurs in infants and children will be reviewed here. The approach to evaluating cardiac murmurs, identifying newborns with critical heart disease, and evaluating children with suspected heart disease are discussed separately:

(See "Approach to the infant or child with a cardiac murmur", section on 'Heart murmurs'.)

(See "Identifying newborns with critical congenital heart disease".)

(See "Suspected heart disease in infants and children: Criteria for referral".)
