[Analysis of the right ventricular function by simulation (author's transl)]

Area of Science:

• Cardiovascular physiology
• Biomedical engineering
• Cardiac mechanics

Context:

• Previous studies explored replacing right ventricular components with prosthetics.
• A novel epicardial chamber demonstrated pulsatile pressure generation.
• Understanding the right ventricle's pumping mechanism is crucial for cardiac repair.

Purpose:

• To quantify the contribution of the interventricular septum and free wall to right ventricular function.
• To utilize a simulator to analyze the biomechanical performance of the right ventricle.

Summary:

• The interventricular septum did not contribute to right ventricular pump action.
• Septal movement was observed towards the left, not into the right ventricular cavity.
• The interventricular groove shift was limited to the apical half of the ventricle.

Impact:

• This research clarifies the functional roles of right ventricular structures.
• Findings inform the design of more effective cardiac prosthetics and surgical interventions.
• Provides insights into right ventricular mechanics for treating heart conditions.
