Redo TAV
Transforming aortic procedures for cardiothoracic surgeons.
For over 40 years, MHIF has been one of the leading nonprofit research and education institutions in the country. With over 230 active research studies and publications ongoing each year, the organization improves the cardiovascular health of individuals and communities through innovative research and education.
The Opportunity
Led by a world-renowned cardiothoracic surgeon on MHIF’s Valve Science Center Research Team, our team was approached to build the Redo TAV mobile app which completes the suite of apps previously designed and built by KRUTSCH.
The Outcome
A mobile application that enables clinicians to measure the coronary risk to their patients in need of a valve replacement, with both online and offline operability.

"KRUTSCH made it possible to design and deliver the most complex App we have yet developed which will have a global impact on how complex patients are treated. They worked with our team seamlessly to adapt and design the complex workflow while also maintaining the theme used in previous Apps."

The Goal
Continuing our work with MHIF, KRUTSCH approached the project from both a design and backend perspective focusing on accessibility and utilizing existing patterns from this family of apps to speed up the development process where possible.
The Design Focus
With Redo TAV being part of the MHIF suite, it was really important that it looked and felt like it belonged with the pre-existing apps. We maintained commonalities to the other apps, but strictly followed material guidelines to ensure that the app remained accessible, that the component library was consistent, and, additionally, material makes designing for dark mode easy.
The Development Focus
While Redo TAV has similarities within the design as the other MHIF apps, we had a very iterative development process that unfolded. As we dove deeper into development, the scope of the project expanded, and our dev team had to account for a variety of conditions and user behavior that could end up problematic if the logic wasn't carefully designed.
Getting to Work
Similarly to our previous projects with MHIF, we started with a series of workshop sessions to discuss content and functionality of Redo TAV. The main use case for Redo TAV was giving clinicians the ability to assess risk to the coronary arteries when a replacement valve was needed, but providing procedural guides and procedure end data outcomes were beneficial for users to reference.
It was important that Redo TAV fit in with the existing MHIF apps, but we iterated on the design as necessary for features, like CT Planning and Procedure Quick Guide, that were unique to Redo TAV. With an agreed upon visual language adapted using Material Guidelines, we built out high fidelity screens in Figma that were then prototyped to walk users through what their experience would be when going through all the steps of CT Planning and reviewing their risk assessment and summary report.
Maintaining a low-code approach, we worked with the MHIF team to upload content for REDO Tav into Airtable. Airtable allowed for quick data entry and gives the MHIF team a lot of flexibility to update app content as needed. As content is added, or edited, the Airtable scripts that were written could be run to push updates to the users phones.
Staying true to the suite of MHIF apps, we kept user navigation throughout the app to tap gestures when possible. REDO Tav gives clinicians offline operability if needed to measure the coronary risk to their patients in need of a valve replacement, and it is now supported by a relational database filled with content via the cloud managed by MHIF.
