VCS is proud to be one of the first cardiology practices in Central Virginia to offer the world’s smallest pacemaker to help treat patients with bradycardia. Dr. David Gilligan and Dr. Guru Mohanty are now implanting the device at Chippenham Hospital. The Micra® Transcatheter Pacing System provides patients with the most advanced pacing technology at one-tenth the size of a traditional pacemaker.
Bradycardia is a condition characterized by a slow or irregular heart rhythm, usually fewer than 60 beats per minute. At this rate, the heart is unable to pump enough oxygen-rich blood to the body during normal activity or exercise, causing dizziness, fatigue, shortness of breath or fainting spells. Pacemakers are the most common way to treat bradycardia to help restore the heart's normal rhythm and relieve symptoms by sending electrical impulses to the heart to increase the heart rate.
What is the Micra Pacemaker?
• Comparable in size to a large vitamin, the Micra TPS is a miniaturized heart device designed to provide the most advanced pacing technology – all while being cosmetically invisible.
• Made by Medtronic, the Micra TPS is unlike traditional pacemakers because the device does not require cardiac wires (leads) or a surgical “pocket” under the skin to deliver a pacing therapy.
• Designed to provide a safe alternative to conventional pacemakers – without the complications associated with leads – the Micra TPS is small enough to be delivered through a catheter and implanted directly into the heart with small tines and delivers electrical impulses that pace the heart through an electrode at the end of the device.
• Customized to each patient’s needs, the Micra TPS automatically adjusts pacing therapy based on a person’s activity levels.
