NCT02105480

Brief Summary

The purpose of this double-blind pivotal clinical utility study is to determine on a large patient population whether heart murmurs can be reliably detected with high sensitivity and specificity using a locked, automated algorithm-based phonocardiogram analysis (also referred to as computer aided auscultation (CAA)). Each patient is auscultated and diagnosed independently by a medical specialist. Additionally, for each patient, an echocardiogram is performed as the gold-standard for determining heart pathologies. The CAA results are compared to the findings of the medical professionals as well as to the echocardiogram findings. Hypothesis: The specific (locked) CAA algorithms used in this study are able to automatically diagnose pathological heart murmurs in premature babies and newborns with at least the same accuracy as experienced medical specialists.

Outcome Measures

Primary Outcomes (1)

  • Number of correctly diagnosed heart murmurs through locked, independent algorithm based auscultation and traditional stethoscope based auscultation by medical experts

    Each patient is screened and diagnosed regarding a potential heart murmur by a medical expert through standard stethoscope based auscultation. Heart sounds are recorded using an electronic stethoscope and analyzed and diagnosed independently (with no external input) by a locked algorithm. A final diagnoses for each patient is made by a medical expert by performing an echocardiogram, the gold standard method for heart murmur detection. The diagnoses of both the medical expert and the algorithm are finally compared to the echocardiogram based diagnosis (after completion of patient recruitment).
