MedStar Heart & Vascular Institute Offers Patients World’s Smallest Pacemaker
Miniature Heart Device Provides Patients with the Most Advanced Pacing Technology Available
March 13, 2017
BALTIMORE, Md – [March 13, 2017] The MedStar Heart & Vascular Institute at MedStar Union Memorial Hospital is now offering the Micra trans-catheter pacing system (TPS), the world’s smallest and most advanced pacemaker available, to patients with bradycardia and other single chamber cardiac rhythm disorders. Drs. Glenn Meininger and David Schamp first used the wireless device last week when they implanted the vitamin-sized pacemaker directly into a patient’s heart.
Weighing the same as a penny, TPS is one tenth of the size of standard pacemakers.
Dr. Meininger, medical director of the electrophysiological program for the Baltimore region, implanted the device by inserting a wire catheter through a small incision in the groin and threading the TPS through the femoral artery, into the right ventricle of the patient’s heart. The fully miniaturized pacemaker is self-contained with a battery, and attaches to the heart with small tines. By comparison, a standard pacemaker is surgically implanted under the collar bone, or sewn into a pocket flap of skin. It attaches to the heart with electrode wires that run through the chest’s venous system to the device.
“This little device is quite sophisticated in its design,” said Dr. Meininger. “Because it’s implanted minimally invasively, there’s significantly less risk of complications or infection. It’s cosmetically invisible- no surgical scar, and the patient can be active almost immediately after its implanted. This is truly an exciting advancement in cardiac rhythm pacing therapy, and I am happy to be able to offer the option to our patients.”
Like a standard pacemaker, TPS sends electrical impulses to the heart to help restore a normal heart rhythm to patients suffering bradycardia, a slow heart rhythm. Bradycardia impedes the heart’s ability to pump enough oxygen-rich blood to the body during normal activity, causing dizziness, fatigue, shortness of breath or fainting spells
The Micra TPS has a 12-year battery and is designed to be retrievable.
