Brief Summary: This study will characterize the accuracy of a commercially available artificially-intelligent stethoscope in determining which childhood murmurs suggest underlying congenital structural heart disease and therefore warrant diagnostic echocardiograms.

Detailed Summary:

Heart murmurs can be ausculted in most pediatric patients, but underlying Congenital Structural Heart (CSH) Disease is rare. Nevertheless, CSH Disease is often first suggested by the presence of a murmur. Primary care providers refer pediatric patients to Cardiologists for murmur evaluations with low accuracy, and this pattern results in:

  1. needless emotional strain on many patients with functionally normal hearts and their families,
  2. increased morbidity and mortality rates for rare patients with delayed cardiac diagnoses, and
  3. exorbitant costs to society.

Referral accuracy for murmur evaluations probably is low because the differences between innocent and pathological murmurs can be subtle. Computer-assisted analysis of heart sounds may increase the accuracy of primary care referrals to pediatric cardiologists, but the accuracy of the only FDA-approved artificially-intelligent cardiac auscultation system, Zargis Medical Corporation's Cardioscan®, has never been determined prospectively in an unselected population of live pediatric patients. As a primary endpoint, the study herein proposed would prospectively compare the sensitivity and specificity of the Cardioscan® with that of CHMCA's Pediatric Cardiologists in the identification of cardiac pathology among 300 new and unselected pediatric patients referred to CHMCA's cardiologists for murmur evaluations, using two-dimensional transthoracic echocardiography as the common gold-standard. Double-blinding will be in place. The study also will attempt secondarily to gauge the clinical significance of pathology missed by the Cardioscan®, to define sub-populations of patients among which the Cardioscan's® judgment should be considered less accurate, and t

Current Primary Outcome: Sensitivity of the Artificially-Intelligent Stethoscope as compared with that of Pediatric Cardiologists in determining which patients needed echocardiograms because they have congenital structural heart disease [ Time Frame: Not applicable; all data collection for any given patient will be completed within less than 12 hours--usually MUCH less than 12 hours. ]

Original Primary Outcome: Same as current

Current Secondary Outcome: Specificity of the Artificially-Intelligent Stethoscope as compared with that of Pediatric Cardiologists in determining which patients needed echocardiograms because they have congenital structural heart disease. [ Time Frame: Not applicable; all data collection for any given patient will be completed within less than 12 hours--usually MUCH less than 12 hours. ]

Original Secondary Outcome: Same as current
