The U.S. Food and Drug Administration today approved the Optimizer Smart system for treating patients with chronic, moderate-to-severe heart failure who are not suited for treatment with other heart failure devices such as cardiac resynchronization therapy to restore a normal timing pattern of the heartbeat. The FDA gave the device a Breakthrough Device designation because it treats a life-threatening disease, heart failure, and addresses an unmet medical need in patients who fail to get adequate benefits from standard treatments and have no alternative treatment options.
