During traditional PCI procedures, interventional cardiologists are often exposed to significant levels of radiation, as well as physical stresses that place them at risk for orthopedic problems. Robotically enhanced PCI not only has the ability to protect the physician's health, but can also enhance technical precision, allowing stents to be placed even more precisely.
Using the CorPath® 200 robotic system, interventional cardiologists perform PCI from a radiation-protected cockpit in a seated position, without the need for the heavy lead apron. The robotic-assisted system provides a precise computer-controlled motion of guidewire and stent to enable the physician to place stents by using a joystick. Additionally, the cockpit provides a better ergonomic position and view of the angiography screens compared to the traditional procedures. This in turn aids the physician in even more accurate measurements.
"Robotically enhanced PCI has the potential to benefit both patients and interventional cardiologists," said Giora Weisz, MD, director of Clinical Cardiovascular Research at the Center for Interventional Vascular Therapy at NewYork-Presbyterian Hospital/Columbia University Medical Center and the principal investigator of the trial. "This system is designed to place stents with millimeter-level control, while also protecting the physician from radiation exposure."
In the study, 164 patients at nine sites were treated with robotically enhanced PCI using the CorPath 200. PCI was successfully completed without having to convert to manual PCI in 98.8 percent of patients, without device-related complications. The overall procedure success rate was 97.6 percent. Physician exposure to radiation was reduced by 95.2 percent.
"The PRECISE trial demonstrates robotically assisted PCI is safe and feasible for most patients," said Dr. Weisz. "At the same time, robotic treatment can make the procedure safer for the interventional cardiologist as well, by reducing the risk of radiation. In the study, physicians were exposed to significantly lower levels of radiation."
The PRECISE study was sponsored by Corindus Vascular Robotics, Natick, Mass.
Dr. Weisz will present "Final Results and Follow-Up of Robotically-Enhanced Coronary Intervention (The PRECISE Multi-center Pivotal Study)" on Thursday, May 10, 2012 during the Late-Breaking Clinical Trials session beginning at 12:00 p.m. (Pacific Time).
Headquartered in Washington, D.C., the Society for Cardiovascular Angiography and Interventions is a 4,000-member professional organization representing invasive and interventional cardiologists in approximately 70 nations. SCAI's mission is to promote excellence in invasive and interventional cardiovascular medicine through physician education and representation, and advancement of quality standards to enhance patient care. SCAI's patient education program, Seconds Count, offers comprehensive information about cardiovascular disease.
