Clinical trial of MitraClip for secondary MR enrolling

A trial investigating the use of MitraClip in patients with functional, or secondary, mitral regurgitation (MR) is now enrolling. The Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation trial (COAPT) will examine the safety and effectiveness of the device in treating moderate-to-severe or severe functional MR in patients not eligible for open-chest surgery. MitraClip is currently FDA approved for use only in patients with degenerative, or primary, MR. The primary investigator is Gladwin Das, MD, with co-investigator Gregory Helmer, MD.

Transcatheter valve therapy registry monitors outcomes

University of Minnesota Health Heart Care has announced its participation in the Transcatheter Valve Therapy Registry. Established by the Society for Thoracic Surgeons and the American College of Cardiology, the registry monitors patient safety and outcomes of transcatheter valve replacement and repair procedures. Analysis of registry data allows the cardiovascular medical community to understand how these procedures are being adopted in the United States and what impact they are having on patient outcomes. Data from the registry will also assist the medical device industry and the FDA in establishing the quality, safety, and efficacy of new medical devices.

Robotic system aids catheterization procedures

A new robotic-assisted system, employed by University of Minnesota Health physicians, offers added precision to minimally invasive angioplasty and catheterization procedures. With the aid of the robotic system, interventional cardiologists can advance coronary guide wires or balloon or stent catheters a millimeter at a time, accuracy that is difficult to achieve under traditional approaches. To conduct procedures, physicians direct the robotic arm from a console while viewing patient anatomy and movement of coronary stents or guidelines on a real-time monitor. University of Minnesota Health Heart Care at Fairview Southdale Hospital is currently the only facility in the region performing robotic percutaneous coronary intervention with the CorPath system.
