World Heart (WHRT) Stock Price, News & Analysis

World Heart Corporation (WorldHeart) is engaged in the development and sale of ventricular assist devices (VADs), particularly the Levacor Rotary VAD (Levacor VAD or Levacor). VADs are mechanical assist devices that supplement the circulatory function of the heart by re-routing blood flow through a mechanical pump allowing for the restoration of normal blood circulation. VADs are used for treatment of patients with severe heart failure, including patients whose hearts are irreversibly damaged and cannot be treated effectively by medical or surgical means other than transplant. Bridge-to-Transplant therapy (BTT) therapy involves implanting a VAD in a transplant-eligible patient to maintain or improve the patient’s health until a donor heart becomes available. In August 2012, HeartWare International, Inc. acquired WorldHeart.
