M-mode echocardiography in normal children and adolescents: some new perspectives

Area of Science:

• Pediatric Cardiology
• Biomedical Engineering
• Medical Imaging

Background:

• Echocardiography (ECHO) is crucial for assessing pediatric heart health.
• Establishing normative data is essential for accurate diagnosis in children and young adults.
• Current echocardiographic reporting methods may lack standardization for pediatric populations.

Purpose of the Study:

• To determine normal M-mode echocardiography values in a diverse pediatric cohort.
• To develop predictive equations for key echocardiographic parameters.
• To facilitate standardized quantitative M-mode echocardiographic reporting in pediatric cardiology.

Main Methods:

• Computer-assisted analysis of M-mode echocardiograms from 202 children and young adults (25 days to 23 years).
• Graphical display of cardiac measurements against body surface area with regression lines and 2 standard deviation ranges.
• Multiple linear regression analysis to derive predictive equations using age, height, weight, sex, race, and heart rate.

Main Results:

• Normal M-mode echocardiography values were established and graphically displayed for left/right heart parameters.
• Predictive equations for echocardiographic dimensions and function were generated.
• Comparison of derived values with existing published equations indicated consistency.

Conclusions:

• Quantitative M-mode echocardiographic reporting is proposed to be standardized and accessible.
• Developed predictive equations can aid in accurate interpretation of pediatric echocardiograms.
• This work supports the integration of computer-assisted measurements for routine pediatric cardiology practice.
