Quebec man given new kind of mechanical heart

A patient in Montreal has become the first living Canadian without a heartbeat. Last month he was given a brand new mechanical heart that pumps blood continuously using a turbine suspended in a magnetic field.

The medical breakthrough was announced by Dr. Renzo Cecere and Dr. Nadia Giannetti at a news conference at McGill University Health Centre on Wednesday.

With them was Gerard Langevin, the 65-year-old Quebec man who became the first patient to undergo successful implantation of the pump after surgery on Nov. 23.

The device has a turbine that pumps blood from the left ventricle to the aorta. From there the blood is distributed to the rest of the body by the continuous flow pump which is powered by batteries located in pouches on Langevin's body.

"A continuous flow pump does not produce any pulsation," Cecere told CTV News.

"In fact there is only one moving part that is levitated within a magnetic field and therefore there is no friction within that pump, and in the absence of friction there is no wear and tear on the components and if there is no wear and tear we expect this pump will last for a very long time."

Though the device is still in the trial stages and the research is only being done on "end stage" heart patients, the doctors said they believe the technology will change the way heart patients are treated, providing an alternative to heart transplant surgery.

Predicted to last up to 10 years, the Heartmate II should outlast other similar devices, and should match the life expectancy of a transplanted human heart.

Prior to the surgery the patient was very sick, had lost more than 20 pounds, and had very low blood pressure, said Giannetti. He has made significant improvement since receiving the device, however.

"He sailed through the surgery, and you have to understand he was very sick going into the surgery and this is very difficult surgery," Giannetti told reporters.

"He sailed through it and he's recovering very nicely and I expect he's going to go on a very long time with this pump."

Langevin admitted that prior to the operation he felt his time was up after he suffered his second heart attack this summer. He had his first in 2002.

"I was finished... I had no time left... I probably had only a few months left to live,'' Langevin said.

He admitted he was afraid and hesitant about having the implant.

"My wife pushed me a lot to have the operation and I don't regret it.''

The cost of the transplant was $100,000. The MUHC is paying for the procedure.

The Toronto General Hospital also took part in the study.

The device has yet to be approved for use in either Canada or the U.S.

Pretty cool shit.
