WWAUS Blog: How Mick Jagger cancels show, has heart surgery and tweets to his fans that he is okay and ready to come back at age 76.

Mick Jagger’s recent heart surgery has spotlighted a medical procedure that is increasingly being touted as a less invasive alternative for patients suffering from a heart-valve disease.

Billboard reported April 4 that according to sources the Rolling Stones’ frontman had completed a heart valve procedure called a transcatheter aortic valve replacement (TAVR) in New York. The procedure is minimally invasive and allowed doctors to repair a blocked heart valve using a catheter without having to perform open heart surgery.

The Rolling Stones had to postpone their tour and cancel their May 2 concert during JazzFest due to Jagger’s medical condition.

TAVR is less invasive than open heart valve replacement surgery, which requires surgeons to open the chest. The replacement valve is inserted through a tube in the groin and the procedure can take an average of 45 minutes to complete depending on the patient, according to Dr. Pedro Cox-Alomar, an LSU interventional cardiologist who heads the Structural Heart Valve Program at University Medical Center in New Orleans. The group has performed TAVR procedures at UMC for the past year and along with Ochsner Health System, are the only providers who perform the procedure in New Orleans.
