Abstract
A 76-year-old woman underwent mitral valve replacement using a pulmonary artery catheter (PAC). We noted blood leaking from the temperature and the optical module connection port of the PAC when she was transferred to the intensive care unit. We tried to remove the PAC. However, a resistance was noted. A chest radiograph and trans-esophageal echocardiography revealed that the PAC was stitched to the wall of the right atrium. To remove the PAC, reopening the original incision was performed in the operating room. The sutures on the wall of the right atrium were released, and then the PAC was pulled back without resistance. It is necessary to suspect that the PAC is sutured when blood leaking from the PAC connection port.
