On the other hand, patients who had bypass with the aid of a heart-lung machine also had no evidence of a higher risk of lowered mental function afterwards, something that prior studies had suggested might be a concern.<\/p>\n\n<p>The studies were presented Monday in San Francisco at the annual meeting of the American College of Cardiology (ACC).<\/p>\n\n<p>Bypass surgery involves the transplant of a vessel sourced from elsewhere in the patient&#8217;s body to &#8220;bypass&#8221; a clogged artery servicing the heart. The procedure can be done while the heart is temporarily stopped and the patient is placed on a heart-lung machine, or it can be done in an &#8220;off-pump&#8221; mode, in which the surgeon lifts the still-beating heart out of the chest cavity to perform the necessary grafts.<\/p>\n\n<p>Initially, experts worried that off-pump bypass might be too risky, especially for more frail patients.
