Some of the most impressive advances in treating late-stage heart failure have come from the research sector investigating implantable devices. Several very different models of implant are currently under research, each of which is designed to correct specific problems in the failing heart. Whether blood flow can be improved by better regulation of the heartbeat — provided by the pacemaker-type implants used in cardiac resynchronization therapy — or by a pump that physically moves blood out of the heart — provided by a left-ventricular assist device — dedicated devices will certainly play a major role in future heart failure care.
