All those with murmurs underwent echocardiographic examination. All babies presenting later in infancy were also identified, to ascertain the total prevalence of congenital heart disease in infancy.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>Murmurs were detected in 46 babies (0.6%) of whom 25 had a cardiac malformation. The most common diagnosis was a ventricular septal defect, although four babies had asymptomatic left heart outflow obstruction. A further 32 infants from the same birth cohort had a normal neonatal examination but were found to have a cardiac malformation before 12 months of age.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>The neonatal examination detects only 44% of cardiac malformations which present in infancy. If a murmur is heard there is a 54% chance of there being an underlying cardiac malformation. Parents and professionals should be aware that a normal neonatal examination does not preclude a clinically significant cardiac malformation. The detection of a murmur should prompt early referral to a paediatric cardiologist for diagnosis or appropriate reassurance.<\/jats:p>\n                  <jats:p>\n                     <jats:boxed-text position=\"float\">\n                        <jats:sec>\n                           <jats:title>Key messages<\/jats:title>\n                           <jats:list list-type=\"simple\">\n                              <jats:list-item>\n                                 <jats:p>The prevalence of murmurs detected at routine examination of neonates is less than 1%.<\/jats:p>\n                              <\/jats:list-item>\n                              <jats:list-item>\n                                 <jats:p>About half of murmurs are due to an underlying cardiovascular malformation<\/jats:p>\n                              <\/jats:list-item>\n                              <jats:list-item>\n                                 <jats:p>Early referral of all newborn babies with murmurs for definitive diagnosis is recommended<\/jats:p>\n                              <\/jats:list-item>\n                              <jats:list-item>\n                                 <jats:p>The absence of a murmur does not exclude serious heart disease<\/jats:p>\n                              <\/jats:list-item>\n                           <\/jats:list>\n                        <\/jats:sec>\n                     <\/jats:boxed-text>\n                  <\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/fn.80.1.f43","type":"journal-article","created":{"date-parts":[[2009,4,8]],"date-time":"2009-04-08T11:39:47Z","timestamp":1239190787000},"page":"F43-F45","source":"Crossref","is-referenced-by-count":149,"title":["Prevalence and clinical significance of cardiac murmurs in neonates"],"prefix":"10.1136","volume":"80","author":[{"given":"Sean B","family":"Ainsworth","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonathan P","family":"Wyllie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher","family":"Wren","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[1999,1,1]]},"reference":[{"key":"2025090511315053000_80.1.F43.1","doi-asserted-by":"crossref","first-page":"31","DOI":"10.1093\/oxfordjournals.aje.a113979","article-title":"Congenital heart disease: prevalence at live birth.","volume":"121","author":"Ferencz","year":"1985","journal-title":"Am J Epidemiol"},{"key":"2025090511315053000_80.1.F43.2","doi-asserted-by":"crossref","first-page":"381","DOI":"10.1093\/oxfordjournals.aje.a114978","article-title":"Congenital heart disease: incidence in the first year of life.","volume":"128","author":"Grabitz","year":"1988","journal-title":"Am J Epidemiol"},{"key":"2025090511315053000_80.1.F43.3","doi-asserted-by":"crossref","first-page":"344","DOI":"10.1111\/j.1440-1754.1993.tb00531.x","article-title":"The incidence of congenital heart defects in the first year of life.","volume":"29","author":"Kidd","year":"1993","journal-title":"J Paediatr Child Health"},{"key":"2025090511315053000_80.1.F43.4","doi-asserted-by":"publisher","DOI":"10.1007\/BF00801907"},{"key":"2025090511315053000_80.1.F43.5","unstructured":"Hall DMB , ed (1996) Health for all children.
