eMurmur ID - Clinical Performance Evaluation
eMurmur ID - Clinical Performance Evaluation
The differentiation between innocent and pathologic murmurs through traditional auscultation
 can often be challenging, which in the end makes the diagnosis strongly dependent on the
 clinitians experience and clinical expertise. With the development of technology it is now
 possible to help diagnose heart murmurs using computer aided auscultation systems (CAA).
 eMurmur ID is an investigational CAA system (not FDA cleared) and the investigators
 hypothesize that it can distinguish between AHA class I (pathologic murmurs) and AHA class
 III heart sounds (innocent murmurs and/or no murmurs) with a sensitivity and specificity not
 worse compared to a similar FDA cleared CAA system on market.
Inclusion Criteria:

 -  All age groups of patients will be included from 1day old

 -  Patients who are being followed for known congenital heart disease and are returning
 for follow up

 -  Patients referred for a suspected heart murmur

 Exclusion Criteria:

 -  Mismatch between the expert physician's diagnosis (auscultation based) and the
 diagnosis resulting from echocardiography (independently read by a cardiologist
 blinded to the auscultation results). Note: both, the expert physician and
 echocardiography results must independently reach the same diagnosis, which is then
 accepted as the gold standard reference diagnosis to which both devices are compared
 to. This is necessary because not every pathology visible on an echocardiogram causes
 an audible murmur, and not every murmur heard by a medical expert might correlate to
 pathology.

 -  Patient whose behaviour does not allow for a standard auscultation by the physician
 (e.g. a screaming fit).
