David Crosby is on the mend after undergoing emergency heart surgery on Valentine's Day.
A not posted at his official web site informs fans that Crosby "underwent a cardiac catheterization and angiogram, based on results of a routine cardiac stress test. The left anterior coronary artery was found to be 90 percent blocked and two stents were placed to provide blood flow to his heart muscle."
The posting said Crosby avoided a full-fledged heart attack and is "expected to have a full recovery," though he's postponing scheduled solo shows in San Francisco and Los Angeles until April.
The Crosby, Stills & Nash tour starting March 4 in Richmond, Va., will not be affected. Crosby said in the posting that, "I am very glad that I listened to my doctors and my family. It seems I am once again a very lucky man. I'm sorry to have to move the (concert) dates but I promise the music will be good when we do play them."
Crosby, of course, is no stranger to health issues; he had a liver transplant during 1994 and also suffers from type 2 diabetes.
His new album, "Croz" -- his first solo set in nearly 21 years -- debuted at No. 36 on the Billboard 200 and No. 2 on the Top Folk Albums chart after its January 28 release.
