New, Tiny Pacemaker Implanted Directly Into Heart

Half the size of a AAA battery, device requires no surgery, could last 14 years

(COLUMBUS, Ohio) May 2014 – Doctors at The Ohio State University Wexner Medical Center are among the first in the country to implant a tiny, high-tech pacemaker directly into the heart of patients, and to do so without surgery.  Only 24 millimeters in length, the pacemaker is fed through an artery in a patient’s leg and, using tiny prongs, is attached into place on the heart.

“These devices are 90 percent smaller than current pacemakers and don’t require wires or leads to be fed through the patient’s chest in order to work,” said Dr. John Hummel, an Ohio State cardiologist who is among those leading the investigation into the effectiveness of the new generation of pacemakers.

“Getting rid of the leads cuts down on complications considerably,” said Ohio State’s Dr. Ralph Augostini. “I think this is the biggest advancement in pacing technology in nearly 15 years."

Once in place, the pacemaker constantly monitors the condition of the patient and only activates when necessary.  “That allows these devices to be extremely efficient,” Hummel said.  “With that kind of intermittent pacing, they could last as long as 14 years.”

WORLD’S SMALLEST, LEADLESS HEART PACEMAKER IMPLANTED AT OHIO STATE

COLUMBUS, Ohio – It’s about the size of a large vitamin pill and, for the first time in Ohio, the smallest heart pacemaker available is being tested at The Ohio State University Wexner Medical Center.

Doctors at Ohio State’s Richard M. Ross Heart Hospital recently implanted the tiny device in a Columbus woman as part of a global clinical trial to test its safety and effectiveness. Unlike conventional pacemakers, which require a chest incision and electrical leads that run through a vein to the heart, this device is wireless and is threaded through a catheter, then attached directly to the heart muscle.

“With this investigational device, the battery, the pacing electrodes, everything is in a little piece of metal sitting inside the heart. We believe that will eliminate a lot of risk for infection and complications,” said Dr. John Hummel, a cardiologist and principal investigator of the trial at Ohio State.

If this transcatheter, leadless pacemaker technology works the way doctors hope, they say it could not only benefit patients, but the minimally invasive approach would be more efficient.

“I think this could be a significant development in pacing procedures. This could cut our procedure time by more than half,” said Dr. Ralph Augostini, a cardiologist at Ohio State.

For now, the tiny pacemaker is being tested in people with bradycardia who need single chamber ventricular pacing. Bradycardia is a slow, irregular heart rhythm which prevents the heart from pumping enough blood into the body. This can cause fatigue, dizziness, shortness of breath and fainting.

A former librarian, 77-year-old Mary Lou Trejo of Columbus, had been suffering from atrial fibrillation for years. Her heart had slowed, despite medication and other treatments to restore rhythm, so she was eager to be among the first in the United States to participate in this clinical trial.

“The new pacemaker sounded so simple, and I have always thought research is important, so I thought this is a way I could contribute,” Trejo said.

The trial will enroll 780 patients in 50 centers worldwide. Investigators are expected to report initial results later this year, once the first 60 patients have been followed for three months.

The Micra Transcatheter Pacing System (TPS) is made by Medtronic, which is funding the clinical trial. Hummel is a consultant for Medtronic. Augostini serves on a Medtronic advisory board.

World`s smallest pacemaker implanted directly into patient`s heart
Dr. John Hummel (left) and Dr. Ralph Augostini of The Ohio State University Wexner Medical Center are among the first in the U.S. to implant the world`s smallest pacemaker. Roughly half the size of a AAA battery, the pacemaker is designed to monitor the patient`s heart and only activate when needed. It is expected to last up to 14 years.

Tiny pacemaker implanted on patient`s heart without surgery
At The Ohio State University Wexner Medical Center, Dr. John Hummel (left) and Dr. Ralph Augostini use a catheter to implant a tiny pacemaker directly into the heart of a patient. The pacemaker, about half the size of a AAA battery, is 90 percent smaller than traditional models and because it has no wires, or leads, the risk of infection and malfunction is greatly reduced.

New generation of pacemaker is barely bigger than a nickel
Just 24 millimeters in length, a new class of pacemaker is being implanted directly into a patient`s heart. Doctors at The Ohio State University Wexner Medical Center say because the device is 90 percent smaller than current pacemaker models, it can be fed through a catheter placed in a patient`s leg and implanted without surgery.

Her new pacemaker is barely bigger than one pill Mary Lou Trejo takes to control her heart condition
Mary Lou Trejo, of Columbus, Ohio, marvels at the size of the pacemaker she recently had implanted at The Ohio State University Wexner Medical Center. Trejo, 77, has a history of atrial fibrillation which has weakened her heart and caused it to slow considerably. Her high-tech new pacemaker will constantly monitor her condition and will only activate when Trejo`s heart needs help beating normally. That intermittent pacing means her tiny pacemaker could last up to 14 years before needing replaced.

A history of heart disease prompted Mary Lou Trejo to test the future of pacemakers
Because she and several members of her family have been diagnosed with heart disease, Mary Lou Trejo of Columbus, Ohio volunteered to become one of the first patients in the U.S. to have a tiny pacemaker implanted directly into her heart. Doctors at The Ohio State University Wexner Medical Center used a catheter to put the high-tech pacemaker into Trejo`s heart where it could stay uninterrupted for up to 14 years.

Implanting a tiny, high-tech pacemaker without surgery
Doctors at The Ohio State University Wexner Medical Center use a catheter to place a tiny, high-tech pacemaker directly into the heart of Mary Lou Trejo, 77, of Columbus, Ohio. The pacemaker is 90 percent smaller than traditional pacemakers and because it has no leads that are fed from the upper chest into the heart, doctors say the risk of infection and complications could be cut dramatically.
