Undertaker underwent heart surgery in April

The Undertaker (Mark Calaway) and Michelle McCool went through a difficult few weeks earlier this year as Undertaker navigated a heart issue.

Undertaker’s Six Feet Under podcast returned on Thursday with McCool joining the show as its new co-host. On the episode, they revealed that Undertaker underwent heart surgery in April after suffering from chronic AFib (atrial fibrillation), a condition where your heart does not beat regularly, increasing your risk of complications like a heart attack or stroke. Undertaker said he is now “all good” after the procedure, but things could have gone badly if the issue was not found.

Aside from sometimes being out of breath when he’d walk up stairs or play with their dog, Undertaker was not experiencing any significant symptoms. He had a routine heart exam scheduled for the end of March, where it was found that he had been in chronic AFib for a while. Medication did not work and Undertaker ended up having to spend four nights in the hospital a couple of weeks before WrestleMania 41. His heartbeat was off, his ejection fraction was low, and doctors had to shock his heart back to normal rhythm, but it only lasted 24-48 hours before he was back in AFib.

Undertaker said he wasn’t supposed to go to Las Vegas for WrestleMania 41 weekend because of the heart issue, but he still made the trip. He helped induct his wife McCool into the WWE Hall of Fame on the Friday night before WrestleMania. Shortly after getting home from Vegas, Undertaker had surgery done.

“That was a rough five weeks,” McCool said. “Everybody came up to me like, ‘How was Hall of Fame? How was this?’ And I did enjoy it literally when I stepped out on the stage, but we had a lot more important things going on before then.”

Undertaker, 60, has been retired from the ring since 2020. He and McCool will both be coaches on season two of WWE LFG, which premieres on A&E on June 22. Undertaker was also a coach on the first season of the show, while McCool is replacing Mickie James for season two.
