Cardiac surgeons prove decreased mortality with off-pump coronary artery bypass grafting

06.05.2003

NYU Medical Center’s cardiac surgeons Eugene Grossi, MD, and Aubrey Galloway, MD, announced new study findings demonstrating significantly lowered mortality, stroke, and overall risk of complications using off-pump coronary artery by-pass grafting (OPCAB) in high-risk patients. The findings were presented today during the Adult Cardiac Surgery Scientific Session at the 83rd annual meeting of the American Association of Thoracic Surgeons (AATS) meeting in Boston, MA.

One of the most exciting, and albeit controversial, innovations in coronary artery bypass grafting (CABG) over the past five years has been the introduction of “beating heart” or “off-pump” surgery. During this approach certain areas of the heart are immobilized with cardiac stabilizers allowing the heart to continue beating during surgery instead of placing the patient on conventional cardiopulmonary bypass (CPB).



NYU’s cardiac surgical research team conducted this study over 10 years to access the efficacy of off-pump coronary artery bypass versus conventional techniques in high-risk patients with severe aortic atherosclerotic disease.

According to Galloway, Director of Cardiac Surgical Research and co-investigator, “This is a very positive study for cardiac surgeons and their patients. Today, we are being asked to treat more patients who are older and have more co-existing conditions than patients a few years ago. Cardiac surgery has evolved to address this changing trend, and coronary artery bypass can now be done in a less traumatic way, minimizing risk in these older, more severely diseased patients.”

Outcomes data were collected on 5,737 CABG patients, identifying 913 patients as high-risk from advanced aortic atherosclerosis, using intraoperative transesophageal echocardiography. Of the high-risk patients, 235 underwent OPCAB, and a propensity case match analysis was conducted comparing data on 229 high-risk OPCAB patients with 229 high-risk conventional CPB patients. Results demonstrated a lower hospital mortality (6.5% vs 11.4%), lower risk of stroke (1.6% vs 5.7%) and better freedom from all complications (92.2% vs 80. 0%) in the OPCAB patients. Hospital stay was also 2 days shorter in the OPCAB patients.

“Despite recent advances in angioplasty and stenting, coronary artery bypass surgery is still necessary for hundreds of thousands of patients a year and this study demonstrates an approach for making the surgery safer in elderly, high-risk patients,” says Grossi, principal investigator of the study.

NYU’s cardiac surgical program is internationally recognized for both clinical care and innovative research. This study shows the risk-lowering benefits of newer techniques and evolving technologies in patients requiring coronary artery bypass grafting.

Im Focus: OLED microdisplays in data glasses for improved human-machine interaction

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

Im Focus: Artificial Intelligence Helps in the Discovery of New Materials

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

Im Focus: Complex hardmetal tools out of the 3D printer

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.

Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...

Im Focus: Launch of New Industry Working Group for Process Control in Laser Material Processing

At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.

In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...

Every three years, the plastics industry gathers at K, the international trade fair for plastics and rubber in Düsseldorf. The Fraunhofer Institute for Laser Technology ILT will also be attending again and presenting many innovative technologies, such as for joining plastics and metals using ultrashort pulse lasers. From October 19 to 26, you can find the Fraunhofer ILT at the joint Fraunhofer booth SC01 in Hall 7.

K is the world’s largest trade fair for the plastics and rubber industry. As in previous years, the organizers are expecting 3,000 exhibitors and more than...
