"The minor TIA [transient ischemic attack] revealed that I have a PFO [patent foramen ovale], a hole in my heart that never closed," the mother-of-six said. She explained that she suffered a stroke because a blood clot was "able to cross over through the hole."
With that said, she is disappointed that she's no longer competing on DWTS, and so are her fans. The ABC show refused to reverse their decision even after an online petition garnered more than 20,000 signatures in an attempt to bring Zolciak back to the competition.
The Bravo star is still keeping positive. "I love Dancing With the Stars," she told Strahan. "It's been the best experience of my life."
While she won't be able to win the mirror ball trophy, Zolciak will hit the dance floor one last time. The 37-year-old confirmed that she will be back for the DWTS finale along with all the other contestants from this season.
Judge Carrie Ann Inaba told ET that she's sticking to her guns when it comes to keeping the Don't Be Tardy star returning as a competitor. "I feel bad for her but those are the rules, and you know, I am a strong abide by the rules," Inaba said. "It would be unfair to the other competitors."
