BACKGROUND:

Significant advancements in heart failure therapy are occur through the use of Ventricular Assist Devices (VADs). Cardiovascular diseases are the leading cause of death globally, affecting millions. Heart failure (HF) is a common condition, especially in patients over 65, and is linked to high rates of hospitalization, mortality, and readmissions. Heart transplant, while a treatment option for HF, faces significant challenges like donor scarcity and postoperative complications such as organ incompatibility, infections, and damage to other organs. Therefore, na efficient, lower-risk solution is sought.

METHODS:

Them VADs have emerged as a promising alternative. They can be used while waiting for a heart donor, as a bridge to recovery, or as definitive therapy. A key complication of VADs relates to the external controller, which is connected to the implanted pump via a percutaneous cable and can cause infections.To mitigate this, the Health 4.0 concept introduces the IoT concept like an implanted controller in the patient’s body, reducing infection risk and enhancing quality of life. For interaction with this controller, a wireless Human-Machine Interface (HMI) is required. This interface allows control parameter adjustments for the VAD. Utilizing mobile devices for the HMI enables patients and doctors to access the VAD controller, removing the need for patients to be constantly connected to a nearby machine. Through the HMI, interaction with the VAD is possible, allowing real-time data display and information receipt for patient diagnosis.

RESULTS:

The HMI development for mobile devices allows patients and doctors to easily access the VAD controller, facilitating interactions such as displaying real-time data and receiving diagnostic information. Furthermore, doctors and caregivers can send commands to the controller, like adjusting the VAD. The proposed application contains monitoring screens with line graphs, user profile screens, command screens, and login screens, with authentication and authorization schemes.

CONCLUSION:

Designing and surgically introducing a fully implantable VAD is complex, but the benefits are vast. This approach not only reduces mortality rates but also improves patient quality of life, decreases infection risk. The fully implantable VAD represents advancement in medicine. As technology progresses, VADs evolve, becoming realistic and viable alternatives for patients ineligible for transplants. The project’s development technology is Oracle Apex, a free low-code development platform that allows the creation of applications using pre-defined HTML, CSS, and JavaScript templates. The data sent by the controller will bestored in separate tables, such as blood temperature and heartbeat tables. With data collection and analysis from the VAD, valuable information for patient diagnosis and monitoring can be provided using IoT and the big data concept, enabling more in-depth studies through cloud computing using the stored data.
