heart lung machine

NEW YORK (AP) -- It seemed like a great idea - doing bypass surgery while the heart is still beating, sparing patients the complications that can come from going on a heart-lung machine.

Now the first big test of this method has produced a surprise: Bypass has fewer problems and is more successful done the old way....

Use of a heart-lung machine during coronary-artery bypass grafting (CABG) doesn't impair outcomes or cognition any more than "off-pump" procedures, according to results of a large randomized trial.
