Area of Science:

• Biomedical Engineering
• Cardiovascular Technology
• Artificial Organs

Background:

• Ventricular Assist Devices (VADs) are crucial for end-stage heart failure treatment.
• Current VAD control systems often lack dynamic adaptation to patient physiological status.
• Need for improved VAD management to enhance patient outcomes and quality of life.

Purpose of the Study:

• To develop and present an innovative algorithm for the dynamic control of VADs.
• To enable VAD hydraulic power adjustment based on continuous physiological and functional parameters.
• To explore new therapeutic approaches for heart failure management through intelligent VAD control.

Main Methods:

• Acquisition of continuous physiological data (heart rate, blood oxygenation, temperature) and patient movements using wearable devices (MagIC & Winpack) and implanted sensors.
• Development of an algorithm to dynamically control VAD hydraulic power.
• Integration of patient activity and emotional status into the control algorithm.

Main Results:

• The proposed algorithm enables dynamic VAD control based on real-time physiological feedback.
• Demonstrated potential for autoregulation of cardiac dynamics in sensorized VADs.
• Successful integration of wearable and implanted sensor data for adaptive VAD function.

Conclusions:

• The developed algorithm offers a novel approach to VAD management.
• Continuous monitoring and dynamic control can significantly improve VAD therapy for heart failure patients.
• This technology paves the way for more personalized and responsive cardiac support.
