Total hospital cost of robotic or conventional open-chest mitral valve repair surgery is similar
Date:9/30/2013

ROCHESTER, Minn. --The total hospital cost of mitral valve repair surgery -- from the time a patient is admitted to the hospital until release --is similar, whether performed through small port incisions using robotic equipment or via the conventional open-chest method, a Mayo Clinic study of 370 patients found. Importantly, robotic surgeries were just as safe as conventional open procedures, but patients who underwent robotic mitral valve repair recovered more rapidly and returned home earlier than patients who had open-chest surgery, the study found. The results of the study also reflect systems innovation efforts designed to reduce the cost of high-technology cardiac care. The findings will be published online Oct. 1 in Mayo Clinic Proceedings.

"These results reflect an important opportunity to decrease cost and improve quality of U.S. health care when technologically complex procedures are performed by well-trained, high-volume teams capable of leveraging the potential of less invasive approaches for patient benefit," says lead author Rakesh Suri, M.D., D.Phil., a cardiovascular surgeon at Mayo Clinic in Rochester.

Patients undergo mitral valve repair surgery for severe mitral valve regurgitation, a common condition that is increasing in frequency. By 2030, an estimated 5 million Americans will have moderate to severe mitral valve regurgitation. The condition occurs when the mitral valve does not close properly, causing blood to be pumped backward instead of forward. Oxygen-rich blood is thus unable to move through the heart to the rest of the body as efficiently.

In robot-assisted cardiac operations, small incisions are made on the right side of the chest, and the surgeon conducts surgery using a robotic telemanipulator system, which includes a high-definition camera and thin mechanical arms that act as extensions of the surgeon's eyes and hands. In open-chest surgery, the surgeon cuts down the center of the chest along
