Paul McCartney underwent a secret heart operation in November, it was revealed last night.

A source told the Sun: “Paul had been complaining about not feeling well and saw a Harley Street specialist at The London Clinic.”

“Tests were carried out and the decision was taken to operate. Paul had a coronary angioplasty in a private hospital. It was all very routine but any work on your heart is a big deal.”

The source added that the 65 year old former Beatle “is in very good shape. He does regular exercise and is fit. He eats well and does not carry any excess weight. He has always been in exceptional health, which is remarkable when you think of the rock ‘n’ roll lifestyle he once had.”

“[But he] felt there was something not quite right and sought professional help. Thankfully the operation went well and Paul feels great.”

The operation helps unclog arteries in the heart to allow blood to flow better through the organ.
