Lisa was recently diagnosed with severe mitral valve regurgitation due to due to mitral valve prolapse. That said, Lisa is currently searching for a heart surgeon. She writes to me, “Hi Adam: I live in New York…. And, I am curious… Do you know the name of David Letterman’s heart surgeon?”

As you may know, David Letterman had emergency heart surgery on January 14, 2000 at NewYork-Presbyterian Hospital in New York. David Letterman’s surgeon was Doctor O. Wayne Isom, the Chief of Cardiothoracic Surgery. Due to a blocked artery, Letterman had quintuple heart bypass surgery.

Dr. Wayne Isom

As a result of heart surgery, Letterman missed his first television show in twenty years of late night entertainment. In total, Letterman was out for five weeks during his recovery. Upon Dave’s return to The Late Show, there was a week-long celebration featuring Jerry Seinfield, Julia Roberts, Rudy Giuliani, Bill Cosby, Regis Philbin, etc.

As for Doctor O. Wayne Isom, Letterman’s surgeon, he too is a very celebrated person. Recognition for Dr. Isom’s work includes:

The Greenberg Prize
The American Heart Association’s distinguished Bugher Foundation Award for Achievement in Cardiovascular Science and Medicine
The Hero With A Heart Award from the National Marfan Foundation
The first annual Humanitarian Award from the Larry King Cardiac Foundation
The NYSAE Education Research Foundation
The highly coveted Third Year Teaching Award from Weill Cornell Medical College’s medical students.

I hope that helps you better understand a little bit more about David Letterman’s heart surgery and Doctor O. Wayne Isom, Letterman’s heart surgeon.

I am currently in the process of having Dr. Adams in NY (that Adam speaks of above) review all of my records & tests as I have 100% regurgitation, mitral valve is shot, and needs fixing! It took them ONE day to get my faxed information and CALL ME!! And I am in California! It is a Mitral Valve Repair CENTER … that’s their specialty. They will review all requests for referrals. I want to be SURE I must have a replacement valve … be SURE it can’t be repaired. That is why I am having them review everything. I encourage you to go to the website, there is abundant information there. Dr. Adams is on vacation until Sept. 22 … but after that he will be arranging a conference call for my husband & I to let us know what he feels is the right thing to do. IF I LIVED in NY … I’d be at his door TODAY 😉 !!!
