A multidisciplinary team from the Montreal Heart Institute (MHI), which is affiliated to the Université de Montréal, performed its first catheter implantation of a new prosthesis (Amptlazer® Cardiac Plug) closing the appendage of the left atrium of the heart, which will have the effect of preventing the formation of blood clots and avoiding open-heart surgery.
This is excellent news for patients suffering from atrial fibrillation, the most common form of cardiac arrhythmia, affecting at least 5 percent of Canadians over the age of 70. This innovation takes place within the framework of a pan-Canadian program that includes the Institut de cardiologie et de pneumologie de Québec, the Toronto General Hospital, St. Paul's Hospital in Vancouver, as well as the MHI.
Pooling expertise, convincing results
The team that performed the first three procedures at the MHI on November 25, 2009, was composed of Drs. Réda Ibrahim, interventional cardiologist, Arsène Basmadjian, cardiologist and ultrasound specialist, and Antoine Rochon, anesthesiologist, all professors at the Université de Montréal, as well as Drs. Patrick Garceau, fellow in echocardiography, and Hasan Jilaihawi, fellow in interventional cardiology, plus nurses and a radiology technician. The results of the procedure were favourable for all three patients, who are well today. The members of the MHI team worked under the supervision of Dr. Rainer Schräder, head of the department of cardiology and intensive care unit at the Makus-Krankenhaus Centre in Frankfurt, Germany, the technique having already been used on a regular basis in Europe for over a year. Drs. Erick Horlick of the Toronto General Hospital and John G. Webb of St. Paul's Hospital in Vancouver were also present with a view to soon being able to perform similar procedures in their own institutions.
"We are delighted at being able to pool our expertise so as to offer a promising alternative to patients with atrial fibrillation and, in doing so, bring hope to these patients. By preventing clot formation, this prosthesis makes it possible to prevent cardiovascular accidents (CVA) and calls for a less invasive procedure in comparison to open heart surgery," said Dr. Réda Ibrahim.
Given its volume of activity and expertise in treating cardiovascular diseases, the MHI has also been chosen to serve as a training centre for American cardiologists who must be trained with a view to a study leading to approval of the prosthesis by the Federal Drug Administration (FDA). This training program will begin in early 2010.
About atrial fibrillation
Atrial fibrillation, the most common form of cardiac arrythmia, is associated with significant morbidity. One person in 20 will be affected by it at some point in their lives. Since it is more common in older people, the incidence of atrial fibrillation is rising as the population ages. From a clinical standpoint, it can cause palpitations, fatigue and syncope (fainting). Under normal conditions, the atria (the chambers of the heart that receive blood from the veins of the body and lungs) pump blood into the ventricles, which in turn pump it to the lungs and peripheral areas of the body (brain, kidneys, legs, etc.)
In atrial fibrillation, the atrial contractions become rapid and irregular. Blood can pool in the heart's chambers, which may lead to the formation of clots that can cause peripheral embolisms or strokes.
About the Montreal Heart Institute
Founded in 1954 by Dr. Paul David, the Montreal Heart Institute constantly aims for the highest standards of excellence in the cardiovascular field through its leadership in prevention, ultra-specialized care, training of professionals, clinical and fundamental research, and assessment of new technologies. It is affiliated with the Université de Montréal and its clinical outcomes are among the best in the world. To learn more about the Institute, please visit our website at www.icm-mhi.org.
About the Université de Montréal
Rooted in Montreal and international in its vocation, the Université de Montréal is one of the largest French-speaking universities in the world. Founded in 1878, the Université de Montréal includes 13 faculties and two professional schools. With its affiliated schools, HEC Montréal and École Polytechnique, the Université de Montréal is the leading centre for higher learning and research in Québec and one of the most important in North America. The Université de Montréal brings together some 2,500 teachers and researchers and is home to over 60, 000 students.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
