New Treatment for Atrial Fibrillation Reduces Stroke Risk
More options for millions of Americans living with a potentially deadly heart rhythm disorder

|The left atrial appendage is a sac attached to the left upper chamber of the heart where blood clots and strokes originate from in patients with atrial fibrillation. The LARIAT procedure is a minimally invasive procedure to close the left atrial appendage to decrease the risk of stroke. 1. A magnetic wire is inserted into the heart through the groin vein, and matched to another wire from the outside of the heart, inserted from a needle stick into the chest wall. 2. The LARIAT suture is advanced across the magnetic wire connection, to the base of the left atrial appendage. 3. The suture is tied down, closing the left atrial appendage. 4. Over time, the left atrial appendage dissolves
STONY BROOK, NY, March 10, 2014 – Doctors at the Stony Brook Heart Institute Electrophysiology Lab are using a new nonsurgical technique called the LARIAT Suture Delivery Device to treat patients with atrial fibrillation, or A-Fib, who cannot tolerate blood thinning medication.
A-Fib is the most common heart rhythm disorder that causes the upper chambers of the heart to beat fast and erratically. An estimated 2.7 million Americans are living with the disorder, and if uncontrolled, can have serious consequences including stroke and early death. Currently the condition accounts for more than 20 percent of stroke-related deaths.
