Robotic-assisted percutaneous coronary intervention--filling an unmet need

Abstract

Percutaneous coronary intervention (PCI) has undergone a remarkable evolution over the past 25 years. Initially, the procedure was limited to relatively straightforward lesions and was associated with significant risk and unpredictable long-term efficacy. With the incorporation of new technologies such as stents, the safety and efficacy of the procedure has improved dramatically. However, the fundamental way in which the procedure is performed has changed little since the time of Gruntzig's first successful case. Cumulative exposure to ionizing radiation, orthopedic injuries resulting from wearing shielding aprons, and fatigue from standing for hours at the table have made the catheterization laboratory a "high-risk workplace" for the interventional cardiologist. Robotic-assisted PCI was developed to allow the operator to precisely manipulate angioplasty guidewires, balloons, and stents from a radiation-shielded cockpit. A small first-in-man study demonstrated that PCI can be performed with robotic assistance. The pivotal Percutaneous Robotically Enhanced Coronary Intervention Study trial is currently enrolling patients and evaluating the safety and efficacy of the CorPath® robotically assisted PCI system.
