St. Michael's Hospital first in Ontario to implant powerful new defibrillator

22.12.2010
Minimally invasive surgeries mean smaller scars, quicker recovery

St. Michael's Hospital today became the first in Ontario to implant a small but powerful new defibrillator into a patient's chest.

The defibrillator – about the size of a Zippo lighter – is the smallest available in terms of surface area and can deliver the highest level of energy, 40 joules.

The narrow shape of the device allowed Dr. Iqwal Mangat to make a smaller incision in the patient's chest, which should mean a faster recovery and smaller scar. The "minimally invasive" procedure is performed on an outpatient basis, with most patients going home the same day. The small size also means less patient discomfort and less obvious signs of the device under the patient's skin.

The high-energy capability of this device is especially important for patients who have an enlarged weak heart, advanced heart failure or have previously required a high amount of energy to shock their heart back to a normal rhythm.. This device is also coupled with an additional lead on the left side of the heart that allows the heart to "resynchronize," potentially allowing patients to feel more energy and less short of breath.

"The more energy there is in a device to shock a patient, the more likely it is their life will be saved by that device," said Dr. Mangat, director of the hospital's arrhythmia services. "Most people don't need a lot of energy, but sometimes they do."

The new Unify CRT-D defibrillator is made by St. Jude Medical, Inc., based in St. Paul, MN.

St. Michael's implants about 290 defibrillators and 230 pacemakers a year.

What is the difference between a pacemaker and an implanted defibrillator?

A pacemaker is about one-quarter the size of a defibrillator. It monitors your heart rhythm – which slows with age and certain medications – and sends electrical pulses to your heart if it is beating too slow or you miss a heartbeat.

A defibrillator is a small, battery-powered device that treats a dangerous fast heart rhythm by delivering a jolt of electricity to the heart. They are typically implanted in patients who have or are at risk for developing ventricular tachycardia or ventricular fibrillation, two types of very fast and life-threatening heart rhythms that originate from the ventricles, the lower chambers of the heart.

About St. Michael's Hospital

St. Michael's Hospital provides compassionate care to all who enter its doors. The Hospital also provides outstanding medical education to future health care professionals in more than 23 academic disciplines. Critical care and trauma, heart disease, neurosurgery, diabetes, cancer care, and care of the homeless are among the Hospital's recognized areas of expertise. Through the Keenan Research Centre and the Li Ka Shing Knowledge Institute, research at St. Michael's Hospital is recognized and put into practice around the world. Founded in 1892, the Hospital is fully affiliated with the University of Toronto.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
