Buckingham's publicist said in a statement Friday that he experienced chest pains last week and was taken to the hospital where he had the life-saving procedure. The 69-year-old rocker is now recovering at home with his family.
“Each day he is stronger than the last,” his wife Kristen Buckingham wrote on Facebook. “While he and his heart are doing well, the surgery resulted in vocal cord damage. While it is unclear if the damage is permanent, we are hopeful it is not.”
She said the past year has been stressful, but she is thankful her husband is still alive.
Last year, Buckingham sued Fleetwood Mac after being kicked off the band's new tour.
In the suit, which named Mick Fleetwood, Stevie Nicks, Christine McVie and John McVie as defendants, the Hollywood Reporter says the guitarist and songwriter sought his share of the tour proceeds because he still wanted and was able to perform and claimed he would be missing out at least $12 million.
Fleetwood Mac disputed the allegations made by Buckingham.
