Hollywood Private Hospital implants Asia-Pacific's First MRI-conditional cardiac resynchronisation pacemaker
Sep 17, 2012
Hollywood Private Hospital is once again at the forefront of medical and technological innovation as one of the hospital’s cardiologists implanted Asia-Pacific’s first ‘MRI conditional’ cardiac resynchronisation (biventricular) pacemaker.
The 71-year-old man who received the revolutionary pacemaker was complaining of worsening shortness of breath and swollen ankles due to fluid accumulation. He was diagnosed with heart failure due to dilated cardiomyopathy (where the heart becomes weakened and enlarged and cannot pump blood efficiently).
His heart failure was difficult to treat despite maximal medications. He had suffered a recent stroke in March 2012 thus necessitating the need for a device that could be implanted to help improve his heart function and still be safe for future possible cranial MRI scans.
Many patients with pacemakers are restricted from undergoing MRI procedures as it interferes with the pacemaker’s functions and leads.
However, the new BIOTRONIK EVIA ProMRI® HF-T device from BIOTRONIK Australia Pty. Ltd, has widened the scope of medical treatment that has previously been restricted for people fitted with cardiac resychronisation pacemakers. This is an important consideration as a significant number of patients with pacemakers may be affected by other conditions that often require MRI scanning.
Cardiac resynchronisation pacemakers are designed to help treat patients with heart failure. It sends small, undetectable electrical impulses to both lower chambers of the heart to help them beat together in a more synchronised pattern. This improves the heart's ability to pump blood and oxygen to the body in addition to medical therapy. The device itself is actually a miniaturised computer and a battery, contained in a small titanium metal case that is about the size of a pocket watch.
Consultant Cardiac Electrophysiologist Dr Shakeeb Razak, who performed the revolutionary procedure, said several thousand people in Australia get a pacemaker implanted every year and many among them may need an MRI scan during their lifetime.
“In the past patients would be barred from undergoing any MRI scanning as exposure to magnetic radiation could cause complications. But this new MRI conditional cardiac resynchronisation pacemaker is a game changer for patients as it ensures they can safely receive future diagnostic imaging as well as advanced features such as comprehensive heart failure diagnostics, the unique patented Closed Loop Stimulation ® (CLS) technology and the BIOTRONIK Home Monitoring® remote monitoring service that allows for early detection of any potential problems. ” said Dr Razak.
Recently appointed Director of Cardiology at Joondalup Health Campus, Dr Jenny Deague said the cardiology team at both Hollywood Private Hospital and Joondalup Health Campus who are part of the Ramsay Healthcare Group, were delighted to lead the way in this medical advancement.
“This is truly revolutionary and demonstrates how we can improve the scope of our care and treatment to more of our patients.”
