Daily Camera has a very positive page 1 article about Boulder Heart introducing an innovative
technology to Boulder County – the world’s smallest pacemaker.
The same article is in the business section of today’s
Longmont Times-Call. A big thank you to
Dr. Sameer Oza and the excellent cardiology team at Boulder Heart.

Boulder Community Hospital first in county to implant world's smallest pacemaker
by Lucas High, Staff Reporter
Boulder Community Health's cardiology team recently became the first
in Boulder County to implant patients with the world's smallest pacemaker.
The device, known as a Micra Transcatheter Pacing System, is about the
size of a vitamin capsule and weighs about as much as a dime, according
to BCH Boulder Heart's Dr. Sameer Oza.
This summer Oza and his team have implanted two patients with the tiny
"I think part of our role as a community hospital is to bring in new
technology," Oza said.
Pacemakers, regardless of size, use electrical impulses to restore natural
rhythm to hearts that are beating slowly or irregularly.
Retired nurse Marilyn Russell, who was being treated for atrial fibrillation,
was one of the first two local patients to receive a Micra device.
"I had researched it and I knew that they had put a few a few thousand
(Micra devices) in patients around the country," Russell said. "I
was excited when Dr. Oza told me I'd be the first person here to get it."
Oza said the Micra device has some distinct advantages over traditional
A traditional pacemaker is implanted through an incision near the collar
bone, while the Micra device is introduced in a minimally invasive procedure
through the femoral artery near the groin.
"Procedurally, there are some benefits," Oza said. "When
you are going in through the collar bone area next to the lung, there
are some potential complications that can happen with the lung."
Because the Micra device is more compact and involves fewer parts, less
hardware is implanted in the body. Less hardware means less risk of infection, Oza said.
Since the Micra device, which has a battery life of 13 to 15 years, is
not introduced through the collar bone area, scarring is not nearly as
visible, he said.
Oza also acknowledges there are some disadvantages to the smaller device,
including the potential for the pacemaker to dislodge and move into the lungs.
"Thankfully, the rate of dislodgment of the Micra is about 1 in 400
to 1 in 500," he said. "That's much lower than the risk
of dislodgment for a traditional pacemaker wire."
About two months after Russell's procedure, she said she's had
no issues with the device.
"I feel wonderful," she said. "Much better than before."
