The 56-year-old percussionist, better known to fans as Clown, opened up about the issue during a recent appearance on Rick Rubin's Tetragrammaton podcast.
Crahan explained that he sought medical attention after feeling unwell once the tour ended, leading doctors to discover a heart problem that now requires surgery.
Slipknot Star Reveals Heart Condition After Recent Tour
According to Setlist.fm, Slipknot last performed live in July 2025 at the Inkcarceration Festival in Mansfield, Ohio.
The appearance followed a busy European summer festival run that included stops in Spain, Portugal, France, Germany, Denmark, Belgium, and Italy.
"I have a skipping heart and I got to get a surgery," Crahan told Rubin. "I found this out after my last tour. I went in, I wasn't feeling good, and I went in and the nurse was trying to get an EKG thing going on and it just wasn't happening."
"I kind of fell asleep and I woke up. I'm like, 'Are you going to get this thing?' And she's like, 'Oh, it's not working.' They thought I was having a heart attack right there. My heart skips and apparently I've taught myself to be like a cross-country runner."
Crahan admitted he is overweight and explained that the condition significantly impacts his heart rate, causing sudden drops that leave him feeling physically drained.
Crahan Says Surgery Should Help Improve Symptoms
The musician said the episodes can feel overwhelming when they occur, "I feel like I'm dying."
"I got to get a surgery," he added. "It's a very easy surgery. You're usually out on the same day. It's not like they rip you open. This is something about the electricity."
Crahan also acknowledged that his career with Slipknot has given him access to specialized healthcare.
"I got a concierge doctor because I'm in Slipknot and I'm able to go to levels and they're like, 'No, you're going to feel better," he said.
"You better get in shape because you got to do more now at 56,'" he said. "And it's just like I just can't believe it, man, that this was me. It's wonderful. I'm lucky."
Currently, Slipknot has no scheduled live performances for 2026.
In April, the band finally released the long-discussed Look Outside Your Window project as part of Record Store Day.
Originally recorded in 2008, the album remained shelved for years and became one of heavy metal's most talked-about unreleased projects.
Only 2,300 copies were released during the exclusive April 18 run.
Crahan previously described the material as more "melodic" than a traditional Slipknot record, with a stronger "rock-music vibe."
