Visually Guided Laser Treats Arrhythmia

Facebook X LinkedIn Email
DALLAS, May 28, 2010 — A new treatment known as a visually guided laser balloon catheter can successfully interrupt abnormal electrical pulses in patients and pigs with intermittent, irregular heartbeats, reports the American Heart Association. Severe cases of irregular heartbeat may require a procedure called ablation, which destroys a group of "misfiring" cells to stop abnormal electrical impulses that cause erratic heartbeats. Investigators aimed at cells in the pulmonary veins, which carry blood from the lungs to the heart. In the clinical part of the study, they ablated the misfiring cells with 100...Read full article
