Mick Jagger, 75, the Rolling Stones icon, recently went in for surgery to have a heart valve replaced after a mystery illness. This caused the Rolling Stones to postpone all future shows.
A source reported shortly after the surgery that Jagger's procedure was successful and was being monitored closely by doctors in New York for signs of complications.
Mick later thanked fans on social media for all their support, saying: "Thank you everyone for all your messages of support, I’m feeling much better now and on the mend - and also a huge thank you to all the hospital staff for doing a superb job."
Jagger underwent a a transcatheter aortic valve replacement (TAVR), a minimally invasive surgery which meant surgeons avoided having to open up his chest. The heart valve was repaired using a catheter that accesses a major artery and he should have a reasonably quick recovery.
