![]() ![]() Using wires as slender as a guitar string, they successfully navigated to the patient’s heart. ![]() But in order to get in there and inject the co2, we have to puncture intentionally puncture a small vein of the heart, with specialized wire in catheter,” Frank said. “My role was pretty simple, straightforward, it was to help him enter the pericardial space, which is normally filled with a little bit of fluid. With the help of interventional cardiologist Adam Frank, doctors performed this technique for the first time at NCH. So by creating a layer of carbon dioxide in it, then we can increase that buffer zone so we can push our needle without touching the heart.” And it’s like only a few millimeters of distance. “Our goal is to get inside the sack, but not touch the heart. And getting to the surface of the heart can be risky, because it can, sometimes there’s a 5% risk of puncturing the heart itself,” Sharma said. And sometimes you have to go on the surface of the heart. “In electrophysiology, we do perform ablation to take care of abnormal tissues, abnormal circuits in the heart. It involved using carbon dioxide to inflate the area, creating a larger work space temporarily. ![]() Using radio frequency to destroy a small amount of tissue responsible for irregular rhythm is a tried and true technique, which is why NCH Electrophysiologist Dinesh Sharma opted for a new approach to reach a delicate area in the lower heart chamber. It makes the operation safer for those who already have a distressed heart. Doctors at NCH’s Rooney Heart Institute are now using a cutting-edge method to operate on patients.
