Help Save Lives With Apraise Aortic Stenosis App



B13 ai’s development of APRAISE-AS for the Royal Wolverhampton Hospital stands out as a beacon of innovation in the management of people with severe asymptomatic aortic stenosis. The challenge is identifying the point at which patients develop symptoms, since often they are mistaken as simply a “case of getting older”. This case study delves into how a mobile application, which is being tested in an NIHR funded trial, could potentially transform the management of people with this condition. Initial trial data indicates that use of the app and its deployment as a part of the trial has been beneficial in leading to earlier identification of symptoms and timely valve replacement, contributing to a better patient journey and improved outcomes for three patients to date.

The Challenge

People living with aortic stenosis risk rapid health decline and poor outcomes should the condition become severe and they develop symptoms. Traditional methods of monitoring have often proven suboptimal particularly in terms of enabling the timely detection of symptoms, which can often go unreported, posing a significant challenge in patient management.

B13’s Innovative Approach

Utilising the ‘Venture Mapping‘ process for scoping and defining the project with the clinical team, B13 transformed a conceptual idea into APRAISE-AS, a powerful tool in the treatment of Aortic Stenosis.

Development Journey

The development journey was a collaborative effort. The origin of APRAISE-AS was a concept envisioned by a forward-thinking team in the Department of Cardiology at the Royal Wolverhampton Hospital, led by Professor James Cotton and Dr Nazish Khan. B13 played a pivotal role in transforming this vision into a tangible, user-friendly app supported by a clinician portal to allow for near real time surveillance of patients’ health status and functional capacity.

The Potential for Life-Saving Impact

The most profound impact of APRAISE-AS is its contribution to saving lives. Documented cases include:

– Early detection and surgical intervention for two patients, directly preventing potential fatalities.
– Diagnosis and treatment of a critical secondary condition in another patient, illustrating the comprehensive monitoring capabilities of the app.

User Experience

Patients have found the app easy to use, contributing to higher engagement and consistent data submission. Clinicians have praised the app for its intuitive design and the actionable insights provided through the clinician portal.

Broader Healthcare Implications

APRAISE-AS’s success demonstrates the power of technology in predictive health analytics and proactive patient care. The application could be adapted for a wide range of conditions with minimal adjustments.


APRAISE-AS, developed by B13 ai showcases how innovative digital solutions can be life-saving. This case study highlights the app’s immediate impact and sets a new standard for the future of healthcare monitoring systems.
