From Modified Haller Index to a Novel Patented Anatomical Measurement Device: Engineering Development, Validation,...

Area of Science:

• Cardiovascular Medicine
• Respiratory Physiology
• Medical Imaging

Background:

• Thoracic morphology significantly impacts cardiopulmonary function and diagnostic imaging.
• The traditional Haller Index (HI) for pectus excavatum requires CT scans and radiation, limiting its use.
• The Modified Haller Index (MHI) was developed as a non-invasive, radiation-free alternative using anthropometry and echocardiography.

Purpose of the Study:

• To review the evolution of thoracic morphometry and the clinical validation of the MHI.
• To introduce a novel patented device for standardized, radiation-free thoracic MHI measurements.
• To highlight the growing evidence on thoracic conformation's clinical significance in cardiovascular and respiratory medicine.

Main Methods:

• Review of historical data and clinical validation studies of the MHI.
• Description of a newly engineered, patented anatomical measurement device for thoracic morphometry.
• Synthesis of evidence linking thoracic morphology to cardiopulmonary phenotypes.

Main Results:

• The MHI is a validated, radiation-free tool for assessing thoracic morphology and its cardiopulmonary impact.
• A novel device standardizes MHI measurements, improving reproducibility and bedside application.
• Elevated MHI values correlate with specific cardiopulmonary phenotypes, including reduced thoracic diameter and altered cardiac/pulmonary function.

Conclusions:

• The MHI and the new measurement device provide a practical platform for standardized, radiation-free thoracic phenotyping.
• Thoracic morphology is a clinically relevant factor across cardiovascular and respiratory diseases.
• Future integration with digital technologies promises advanced digital thoracic phenotyping for precision medicine.
