The Rolling Stones frontman announced earlier this month (Apr19) that the band were rescheduling all their U.S. shows because he needed medical treatment, with rumours then emerging that he had heart issues. 

Now a source has told Billboard.com that the 75-year-old rocker had the operation in New York and is on the road to recovery. 

"Doctors were able to access Jagger's heart valve through his femoral artery and are now monitoring him for any complications that could arise from the procedure, including excess bleeding," the insider explained. 

The procedure, called a transcatheter aortic valve replacement (TAVR), involves doctors repairing the heart valve using a catheter to access the artery without opening the chest - therefore avoiding major surgery. While the recovery time is shorter than if Jagger had had open heart surgery, he will still need to rest for four to five days "so that the artery can heal without any severe bleeding issues".

"He could be up and moving in a few days, but will need some additional recovery time before returning to the stage," the source added. 

The U.S. leg of the band's No Filter Tour was scheduled to kick off in Miami, Florida on 20 April, with 17 shows planned over 10 weeks. However, it's now expected that the dates will be rescheduled for July. 

Following news of the postponement, Jagger issued a statement to fans, expressing his disappointment at cancelling the shows and promising to return to the stage as soon as possible.

"I really hate letting you down like this," he tweeted. "I’m devastated for having to postpone the tour but I will be working very hard to be back on the road as soon as I can. 

"Once again, huge apologies to everyone."
