The university Institute of cardiology and respirology of Quebec has made Friday a canadian first by installing a whole new aortic valve that will change the lives of thousands of patients over the course of the next few years.

The Inspiris Resilia is a valve biological pericardium of calf, which has the peculiarity of expanding as needed. This revolution in the company Edwards allows replacement of the valve at the end of its useful life for a dozen years without even needing to open the patient’s thorax.

The new technology, named “valve-in-valve”, will drop a valve new directly in the first by accessing the heart through the femoral artery, which significantly reduces the impacts on the patients.

“This is a second operation much easier to tolerate. The big benefit is at the level of the recovery. Open-heart surgery, it is three-month recovery, whereas here, the patient could leave the day after the operation and go about her business after two weeks,” explains Dr. François Dagenais, who has performed the first canadian facility to the media Friday, answering questions in real time during the intervention.

The team of cardiac surgeon François Dagenais has practiced this first canadian location of the new valve directly in front of the media, answering questions in real time.

Many of the candidates

This new procedure will provide the valves biological to a range of patients greater because of the ease of replacement. As the devices in membrane porcine or bovine calcifient as a valve, human, these have a limited life span. It is not installed, so not until today on patients less than 65 years of age because of the requirement of réopérer after ten years.

“It lowers with it the age of the installation of valves biological,” says Dr. Daniel Doyle, who is pleased to allow patients to avoid in this way the mechanical valves, which bring their share of complications.

“The mechanical come with anticoagulants, which are the other disease in fact. If we take too much, it bleeds, if it does not enough it blocks it, in short it is binding for the patient,” says the surgeon.

Dr. Daniel Doyle described the work done by his colleague during the operation on Friday morning.

Risk reduction

On some 3000 operations in the heart practiced by the IUCPQ annually, 1000 are replacements of the aortic valves. The novelty presented yesterday morning will therefore have a real impact on the lives of many patients with heart problems.

With respect to the costs related to this novelty, they are similar to those of a mechanical valve and somewhat above those of the other valves organic. So, it is a change at minimal cost to the system, but that will make a real difference.

“These therapeutic approaches offer new treatment options to patients in addition to reducing the risk of complications and mortality,” said Dr. Josep Rodès-Cabau, who has performed in front of the journalists a procedure “valve-in-valve” yesterday, who welcomed the advancement of science. “Before surgery, the patient has a problem of insufficiency in severe and after surgery an hour, in local anesthesia, it has nothing”, has he enchanted.

The surgeon shows the location of the valve in the heart or in the aorta. The new valve is made of pericardium of the calf.

• 3018 operations on the heart, including about 1000 replacements, aortic
• 11 454 procedures in hemodynamics and electrophysiology
• 1367 locations cardiostimulateurs and defibrillators
• 15 heart transplants

The new aortic valve Inspiris Resilia

• Valve pericardium of calf
• Coating anti-calcifiant that extends the duration of life
• The Base of the valve that expands to allow the replacement “valve-in-valve” without a second open-heart operation
• Will allow for the installation of valves on organic patients, more and more young people
• Installed for the first time in Canada at the IUCPQ
