The Rolling Stones frontman Mick Jagger said he is on the mend after undergoing a heart valve replacement procedure in New York earlier this week.

Doctors were able to access the valve through his femoral artery and were monitoring the 75-year-old singer for any complications, Billboard magazine said, in a report that was posted on Thursday and cited unnamed sources.

Jagger tweeted:

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. — Mick Jagger (@MickJagger) April 5, 2019

The procedure, known as trans-catheter aortic valve replacement, or TAVR, is an increasingly widely used alternative to surgical valve replacement that would require the chest to be opened. TAVR typically allows for shorter hospital stays and quicker recovery times.

Jagger had announced on Twitter last Saturday that the band was postponing a tour of the U S and Canada to give him time to recover from unspecified medical treatment.

“I’m devastated for having to postpone the tour but I will be working very hard to be back on stage as soon as I can,” Jagger said at the time.

Originally slated to begin in April, the No Filter tour is now expected to begin in July, Billboard said.
