Clinical Validation of Pouya-Heart
Evidence-Based Research Supporting Early Detection
Pouya-Heart is supported by more than 20 years of clinical and scientific research in pediatric heart-sound analysis. Its development is grounded in peer-reviewed studies conducted in neonatal and pediatric populations, demonstrating strong diagnostic performance, clinical relevance, and real-world usability across different healthcare settings.
Newborn Screening & Early Detection of CHD / CCHD
What was studied
Can Pouya-Heart support early detection of congenital and critical congenital heart disease in newborns?
What studies show
- Accurate identification of CHD and CCHD in the neonatal period
- Detection of heart abnormalities missed by routine clinical examination
- Correct classification of innocent murmurs as healthy
- Analysis of heart sounds at levels below human hearing capability
Key Study: Bordbar et al. (2023)
Large-scale neonatal screening study
Population:
Newborns
Setting:
Hospital neonatal units
Key outcomes:
- Accurate and cost-effective CHD screening
- Identification of defects not detected by standard examination
"We accurately and cost-effectively screened for congenital heart malformations and identified cases not detected by standard medical examinations."Read publication

Murmur Interpretation in Infants & Children
What was studied
Can Pouya-Heart reliably distinguish innocent (normal) murmurs from pathological murmurs in children?
What studies show
- High sensitivity and specificity for murmur classification
- Reliable separation of innocent and pathological murmurs
- Fewer unnecessary referrals
- Effective use by family physicians and non-specialists
Key Study: Kocharian et al. (2013)
Pediatric murmur differentiation study
Population:
Infants and children
Setting:
Pediatric and primary care referrals
"Given the high sensitivity and specificity of the system, its use is recommended to support timely referral, particularly in underserved areas."Read publication

Use in Everyday Clinical Practice
What was studied
Can intelligent heart-sound analysis be used effectively outside specialist cardiology centers?
What studies show
- Reliable use by nurses, family physicians, and non-specialists
- Applicability in hospitals, clinics, and community healthcare settings
- Support for timely and appropriate referral decisions
- Integration into routine clinical workflows
These findings support the use of Pouya-Heart in both specialist and non-specialist care environments.
Book Chapters
The scientific basis of Pouya-Heart is also documented in international book chapters covering:
- Intelligent phonocardiography
- Machine-learning decision-support systems
- Edge computing and connected healthcare
These contributions place CAPIS research within the broader fields of medical informatics and biomedical engineering.
Scientific Dissemination
CAPIS research has been presented at international conferences in pediatric cardiology, biomedical engineering, and medical informatics, contributing to knowledge exchange across Europe, Asia, and the United States.
What the Clinical Evidence Demonstrates
Across multiple studies and populations, the evidence shows that Pouya-Heart:
provides clinically meaningful heart-sound interpretation
distinguishes innocent murmurs from pathological findings
detects abnormalities missed by routine auscultation
supports early and appropriate referral
performs reliably across diverse care settings
