First Patients Benefit from Pioneering Wireless Pacemaker System in UK

A groundbreaking wireless pacemaker system has been utilized by one of the initial heart patients in the UK, a woman from Hampshire. Medical professionals at University Hospital Southampton (UHS) characterized this technology as a “major leap forward,” anticipating its potential to transform lives. Unlike conventional pacemakers that connect to the heart via wires, these innovative devices are designed for direct implantation into two heart chambers, thereby lowering the likelihood of complications. Patient Karen Cooper described the dual leadless pacemaker technology as a “game changer.” The keyhole surgical procedure was overseen by Dr. John Paisey, a consultant cardiologist at UHS. He explained that the two pill-shaped devices, each smaller than a triple-A battery, incorporate advanced implant-to-implant technology. Dr. Paisey stated, “They talk to each other from different chambers of the heart to maintain the normal sequence of cardiac conduction, closer to a normal heartbeat.” Pacemakers function by transmitting electrical impulses to the heart, prompting it to beat at the appropriate rate. Ms. Cooper, 54, received her initial pacemaker at age 17 following a diagnosis of an irregular heart rhythm. Over several decades, the mother from Romsey had undergone seven wired pacemaker implantations. She indicated that she was “running out of options” due to recurring infections and complications, such as a blood clot in her neck. Known as AVEIR DR, this dual wireless system represents a global first. Southampton stands among the initial hospitals in England to adopt this technology. The implantation of the devices into the heart was performed using a specially designed flexible tube, inserted through a vein in the leg. Dr. Paisey acknowledged that wired pacemakers have preserved millions of lives and offered secure, effective treatment for the majority of patients. However, he noted that alternative solutions are necessary for a minority of individuals. He stated: “This new dual-chamber leadless pacemaker system can be a more effective solution for some patients, improving their quality of life and potentially reducing some of the risks associated with traditional pacemakers.” Prior to this, only a single leadless pacemaker was available, which was not appropriate for every patient. According to Dr. Paisey, the new system carries an approximate cost that is 10 times higher than wired pacemakers, and patient prioritization will be based on medical need. Karen Cooper reported feeling well since undergoing the operation in early November. She remarked: “It has made a very big difference. It’s a game changer. I am not worrying about the wires or infections or anything. I can just get on with life.” For updates, BBC Hampshire & Isle of Wight can be followed on Facebook, X (Twitter), or Instagram.
