Accurate modeling of atrioventricular septal defects (AVSD) valves is crucial due to high re-intervention rates. This review found existing modeling platforms need further development for effective AVSD valve study and repair strategy assessment.
Area of Science:
- Biomedical Engineering
- Cardiovascular Research
- Congenital Heart Disease Modeling
Background:
- Atrioventricular septal defects (AVSD) often require repeat surgical interventions.
- Accurate modeling of complex AVSD valve anatomy and repair is essential for improving patient outcomes.
- Current modeling platforms have limitations in addressing AVSD-specific valve pathologies.
Purpose of the Study:
- To systematically review existing modeling platforms for studying abnormal congenital heart valves.
- To assess the applicability of these platforms for atrioventricular septal defect (AVSD) valve investigation.
- To identify gaps and opportunities for developing advanced AVSD valve models.
Main Methods:
- Systematic literature review of scientific sources.
- Screening of 1,050 sources, with 47 included studies.
- Categorization of models into in silico, in vitro, and in vivo approaches.
Main Results:
- In silico models show advancement but rarely target AVSD valves.
- In vitro platforms can compare repair techniques but are not yet used for AVSD.
- In vivo studies offer physiological accuracy but struggle to replicate AVSD pathologies.
- Few existing models are specifically designed or applied for AVSD valve research.
Conclusions:
- Existing modeling platforms require significant advancement for effective AVSD valve study.
- Multidisciplinary efforts are needed to create high-fidelity, reproducible, and physiologically accurate AVSD valve models.
- Improved AVSD valve models can enhance understanding of valve properties and surgical repair strategies.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
