Heart Failure (HF) is a life-threatening chronic condition affecting 26 million people worldwide, in which inefficient heart pumping causes body fluid retention, impacting patients’ quality of life with shortness of breath, fatigue, insomnia, leg swelling among other symptoms. There is still no physiological indicator for increase in body fluid retention and the patient remains asymptomatic for weeks until a sudden, life-threatening condition, Acute Decompensate Heart Failure, arises, resulting in immediate hospitalization. The filling pressure of the left chambers of the heart (Left Atrium Pressure, LAP) increases gradually throughout the process, and is the earliest, most objective marker way to detect ADHF. Vectorious has developed the V-LAP system, the world’s first miniature implant for left-atrial monitoring. The system includes a simple, minimally-invasive implanted device, easy-to-access data and user-friendly wearable device. The V-LAP system helps physicians to help patients help themselves and both reduces hospitalisation and increases CHF patient quality of life. The system has been through preclinical development and is now ready to finalise the engineering of the wearable device and upgrade the software before advancing to clinical testing. The clinical validation will include 20 patients and anticipated to be held in Germany, Italy and the UK.
