Accuracy of Cardiac Auscultation in Asymptomatic Neonates with Heart Murmurs: Comparison Between Pediatric Trainees and Neonatologists

The overall ability of pediatric trainees in identifying congenital heart disease (CHD) was moderate [area under the curve (AUC) = 0.855] and significantly lower compared to neonatologists (AUC = 0.919, p = 0.007). However, at “lower” levels of clinical confidence (i.e., clinical diagnosis of possibly pathologic murmurs), pediatric trainees had good ability in excluding CHD (sensitivity 94.6%; negative likelihood ratio = 0.09). The ability of cardiac auscultation for diagnosing CHD in asymptomatic neonates is limited and dependent on the physician’s experience and level of clinical confidence. Echocardiography should remain an option for all neonates with a possibly pathologic murmur.
Bottom Line: If you are in a place where echocardiogram is not readily read by the pediatric cardiologist, then you may record it with Littman's stethoscope (Digital) and email it. Studies have shown that one can reduce the echiocardiograms being done to rule out a pathjological murmur.
