Active retiree's life saved by TAVR heart surgery
13 Apr
Summary
- A previously healthy 66-year-old experienced a near-fatal collapse.
- Severe aortic stenosis was diagnosed just before a serious cycling accident.
- Less-invasive TAVR surgery allowed for a rapid recovery and return to activities.

John Cantrell, a 66-year-old grandfather who maintained an active lifestyle through cycling and pickleball, was diagnosed with severe aortic stenosis in August 2024. Despite having no symptoms or family history of heart disease, his condition became critical when he fainted and crashed his bicycle the very next day. The accident resulted in broken ribs, a fractured collarbone, and a punctured lung.
Doctors confirmed his blood wasn't being pumped correctly due to the condition. Aortic stenosis, if left untreated, can lead to a median survival of only 18 months and a mortality rate similar to advanced cancers. Cantrell chose the less-invasive Transcatheter Aortic Valve Replacement (TAVR) procedure over a mechanical valve replacement.
Undergoing TAVR surgery in October 2024, Cantrell was amazed by his swift recovery. He successfully completed cardiac rehabilitation, enabling him to resume cycling and treadmill running. He has received positive check-ups and is now focused on spending quality time with his family, including a recent trip to Japan and an upcoming anniversary cruise.
