CorPath Percutaneous Robotically-Enhance Coronary Intervention Study(PRECISE) study states that robotic system is capable of enabling interventional cardiologists to safely conduct percutaneous coronary interventions (PCI).
On using robotic systems, the physician will face only minimal exposure to radiation with enhanced precision and control. This study was presented during the clinical trial at the SCAI 2012 Scientific Sessions.
Interventional cardiologists will be affected by physical stresses and radiations while conducting traditional PCI procedures, while the robotically enhanced PCI procedures ensure increased safety to the physician's health, with increased technical precision, where even stents can be precisely placed.
The CorPath 200 robotic system allows interventional cardiologists to perform PCI. Heavy lead apron are not required as the procedure is conducted in a seated position within radiation-protected cockpit. The robotic-assisted system involves precise computer-controlled movement of guidewire and stent. Also, a joystick is used by the physician to place stents. The cockpit also facilitates better view of the angiography screens and enhanced ergonomic position than other traditional procedures. The physician can have more precise measurements.
The study was conducted with 164 patients at nine sites, who were treated with CorPath 20-assisted robotically enhanced PCI. The procedure was achieved eliminating the need for conversion to manual PCI for about 98.8 % of patients. However, there was no device-related complication. The overall procedure was shown to be 97.6 % successful. Physician exposure to radiation was decreased by 95.2 %.
During the Late-Breaking Clinical Trials session held on May 10 2012, Dr. Weisz presented ‘Final Results and Follow-Up of Robotically-Enhanced Coronary Intervention (The PRECISE Multi-center Pivotal Study)’.
