Herzchirurgie App
Before an aortic valve operation, patients have a list of things to get done: return the admission form, see the dentist, pause certain medications on time, pack a bag. Each of these has its own deadline, and all of them depend on one date: the day of the operation.
Herzchirurgie puts them in one app. You enter your surgery date once, and the app turns every step into a concrete task with a fixed deadline.
Your preparation, step by step
The overview counts down the days until your stay begins and lists the preparation tasks as a numbered timeline, with finished steps checked off. From the day of surgery on, the overview puts recovery first: aftercare and rehabilitation move to the top.
Every deadline is set
Every task is due a fixed number of days before the operation: 14 days for the admission form and the dental check-up, 7 days for pausing medication as described in the invitation letter and for telling family, 1 day for the packing list. The app turns these into real dates ("Bis 19.11.2026") and shows how many tasks are done.
Some tasks only appear when they apply. Privately insured patients, for example, also get "KVNR anfordern": they need to request a health insurance number, which the legally required implant registry asks for.
Check off what's already in the bag
The packing list separates documents from personal items. Every check mark is saved, and a progress bar shows how far along you are. Underlined terms can be tapped for a short explanation, such as why you first wear a hospital gown after surgery.
Explained in plain language
The knowledge section has articles about the operation, each with its reading time. They range from the aortic valve operation itself to waiting times, the intensive care unit, mobilisation, wound care, endocarditis and frequently asked questions.
Surgery moved? Every deadline moves with it
If the operation is rescheduled, you enter the new date in your profile. The countdown, every deadline and every reminder update at once. The app also reminds you not to restart medication on your own that you have already paused, but to talk to your doctor first.
Reminders
If you want, the app reminds you of open tasks three days before they're due and on the day itself, at 9 a.m. Tasks you've finished don't send reminders.
Private by design
Everything you enter is encrypted and stored only on your device. Nothing is sent to the hospital or to third parties, and "Alle Daten löschen" removes it all at any time. The app is deliberately not a medical device. It gives no personal advice on diagnosis or therapy. Which medications to pause, and when, comes from the hospital's invitation letter, not from the app.
