Robotic Heart Surgery Making Repairs without Lifting the Hood. In the United States open-heart surgery was performed without opening the chest in more than a dozen patients. Researchers reported preliminary results at the American Heart Association s Scientific Sessions in 2002. In this procedure surgeons remotely maneuver robotic arms from a seat in front of a console away from the patient. Instead of opening the chest and cutting the skin and muscle to view the area surgeons make four holes 8 to 15 mm each through which robotic arms are inserted. The robotic arms include one with a camera-like device to transmit the image to the console. The other arms are fitted with operating instruments. Surgeons used this new procedure to successfully repair the hearts of patients with atrial septal defect ASD or patent foramen ovale con-ditions in which people are born with an opening between the heart s two upper chambers. This opening allows some blood from the left atrium to return to the right atrium instead of flowing through the left ventricle out the aorta and to the body. It is repaired either by plugging the hole with a patch or suturing the hole closed. Open-heart surgery traditionally requires that surgeons make a foot-long chest incision to cut patients breastbones in half. We wanted to know if it was possible to operate inside the hearts of these patients 218 Chapter 11 Infinitely Expandable without making any incisions says Mehmet Oz . director of the Heart Institute at Columbia-Presbyterian Medical Center in New York. Not only did we show that the operation is feasible but we demonstrated it in more than a dozen patients. During 12 months 15 patients ages 22 to 68 underwent ASD repair using the robotic technology called the da Vinci system described in the preceding section. Although the equipment is costly this is definitely part of the future says Michael Argenziano . lead author of the study and director of .
