Kathryn's Cardiology Story
Kathryn Yost has ‘places to go and things to do’: Heart surgery has helped her get there.
Kathryn Yost has always had “places to go and things to do.” She and her husband, Glenn, love backpacking in the Smoky Mountains, traveling internationally, being outside, and trying new foods.
When a heart condition she had for over 20 years grew progressively worse, she knew she had to do whatever it took to get better.
In 2004, Yost learned she had mild regurgitant mitral valve prolapse, which keeps the heart from functioning the way it should. At first, it was a condition to monitor at yearly appointments — important, but not disruptive to her daily life — but over time, she found herself quietly adjusting to having less energy.
Looking back, Yost traces the shift to a trip to Greece in 2023.
“Of all our international trips, on that one I had to push myself,” she said. “I would have been happy to stay on the boat. I still did everything we planned, but it was a push. I blamed it on the heat.”
Six months later, during an appointment with cardiologist Rebecca McFarland, MD, Yost learned that the mitral valve prolapse was trending toward severe, and they agreed to continue to watch it closely.
Regurgitant mitral valve prolapse occurs when the valve between the heart’s left chambers does not close properly. When the condition becomes severe, it can cause blood to leak backward through the valve, forcing the heart to work harder and leading to symptoms such as fatigue, shortness of breath and reduced stamina.
By her next visit, Yost’s symptoms had become harder to ignore. With less energy, she had gradually pulled back from the activities she enjoyed, and Dr. McFarland recommended treatment.
“I couldn’t stand at the kitchen counter,” Yost said. “I had to sit on a stool.”
Dr. McFarland referred her to cardiothoracic surgeon Sebastian Pagni, MD, who explained the process for repairing the valve through open-heart surgery.
Cardiac rehab: The road to recovery
After surgery, recovery began with small but meaningful steps. Through cardiac rehab, she focused on rebuilding her strength and looking ahead to what life could feel like again.
“Those people became my best friends while I was there,” she said. “They were so encouraging and so fun.”
Within months, Yost rejoined her Silver Sneakers class, returned to serving on the care team at her church, and traveled with Glenn to Norway. She’s now walking six days a week, giving herself Sunday off.
“I’m recovered,” she said. “I would walk from now until forever.”
