THE CANADIAN PRESS/HO, Hamilton Health Sciences MANDATORY CREDIT May 15, 2021 - 6:02 AM A simple surgery to remove unnecessary tissue in the heart could prevent strokes in patients with a common condition that requires them to take blood thinners, says the Canadian lead author of a study involving about 4,800 people in 27 countries. Dr. Richard Whitlock, a cardiac surgeon for Hamilton Health Sciences, said when blood being pumped through the heart pools in the left atrial appendage, it may form a clot that could escape and block the blood supply to the brain and raise the risk of a potentially fatal stroke. But Whitlock says getting rid of an appendage in

Simple surgery prevents strokes in heart patients

Credit: Hamilton Health Sciences Hamilton, ON (May 15, 2021) - A simple surgery saves patients with heart arrhythmia from often-lethal strokes, says a large international study led by McMaster University. Researchers found that removing the left atrial appendage an unused, finger-like tissue that can trap blood in the heart chamber and increase the risk of clots cuts the risk of strokes by more than one-third in patients with atrial fibrillation. Even better, the reduced clotting risk comes on top of any other benefits conferred by blood-thinner medications patients with this condition are usually prescribed. If you have atrial fibrillation and are undergoing heart surgery, the surgeon should be removing your left atrial appendage, because it is a set-up for forming clots. Our trial has shown this to be both safe and effective for stroke prevention, said Richard Whitlock, first author of the study.
