The Undertaker Details Heart Issues, Recently Underwent Surgery

WWE icon The Undertaker has opened up about his recent heart issues and how he underwent surgery shortly after WrestleMania 41.

One of the most recognisable people in pro wrestling history, The Deadman was one of many guests in Las Vegas over WrestleMania weekend. Along with making appearances at WWE World, he also inducted his wife and former Women’s Champion Michelle McCool into the Hall of Fame as part of the 2025 class. However, according to the couple, he was not supposed to travel to the city to be a part of the event.

After a lengthy hiatus, Undertaker’s Six Feet Under podcast returned, this time with McCool as the co-host instead of Matt Lyda. Additionally, the podcast was released on WWE’s YouTube channel as opposed to the standalone show it was previously.

Speaking about what happened, McCool confirmed that her husband underwent heart surgery after the day after they got back from WrestleMania:

Michelle McCool: “It’s because of the heart issues you’ve been having weeks prior. Which, by the grace of god, we found out just by — It ended up being terrifying. The day we got home from WrestleMania, the next day at 6 am, we were at the hospital for a little bit of heart surgery.”

Undertaker: “Just a little bit.”

Michelle McCool: “It was your heart.”

Undertaker: “There was that little sidebar going on.”

Michell McCool: “A sidebar for five weeks. It was terrifying.”

Undertaker: “I wasn’t supposed to go to Vegas.”

Michelle McCool: “You weren’t supposed to go anywhere. You didn’t want me to tell anybody. Not fair to me, not fair. We were in the hospital for four nights two weeks before WrestleMania. Yeah, you weren’t supposed to go. I’m not mad at it because I’d probably be the same [way], but it was terrifying, I couldn’t focus on anything else. All I wanted to focus on was you, your heart, and getting you in with the best cardiologist, which we eventually did but that took a lot of phone calls. Several nights in the hospital. By the grace of god you are here, but out of the words of the doctor himself, it could’ve turned out badly had we not found it that day.”

Undertaker: “You did. You made me go have a test done.”

“I Didn’t Know Anything Was Wrong”: The Undertaker On His Recent Heart Issues

Continuing, the couple also elaborated on when they realised something was wrong with Undertaker, noting that the Hall of Famer also had abnormal readings:

Michelle McCool: “I did. That I had scheduled in January, that’s crazy about it. You went to the doctor March 28th, I’ll never forget. Then you called me and you were like, ‘They won’t run the heart exam.’ Just a routine heart scan that we were gonna do.”

Undertaker: “I didn’t even know that anything was wrong.”

Michelle McCool: “Got you into another [appointment] about an hour later. They had one appointment open. Come to find you, you had been in chronic a-fib for who knows how long. But the scary part was that you didn’t feel any symptoms, so we didn’t know. Yeah, you came in a few times out of breath and I’d bust your balls like, ‘Dude, you were just throwing the ball with the dog, why are you so out of breath?’ Or going up the stairs to pray with the kids, ‘Why are you out of breath’, not thinking it was an actual heart issue. So, yeah. Medicines didn’t work and we ended up in the ER on a Friday. Of course you wouldn’t stay the night. At the end of Kai’s flag football all day Saturday, you looked at me and said, ‘I’m still in a-fib.’ because you were doing it with the watch. I was like, ‘If you’re not out of a-fib when we’re getting ready to go to church tomorrow morning, we’re going to the hospital.’ Thankfully you agreed.

Michelle McCool: “We went to the hospital, numbers were out of wack. Heartbeat was out of wack. Your ejection fracture of how the blood was pumping or whatever was 30%, it wasn’t much. Supposed to be 100%, obviously. We ended up staying in the hospital for four nights where they actually had to cardiovert you and shock you back to a normal rhythm. That sadly lasted, what, 24 hours. Maybe 48. After four days we go home, two days later you’re back in a-fib. Man I was stressed.”

Later in the interview, Undertaker and McCool confirmed that the issues have since been resolved.
