Abstract
BackgroundPulmonary Artery Catheter (PAC) knotting is a rare complication of PAC insertion. In patients with dilated right heart chambers, blind insertion of PAC significantly increases the risk of catheter knotting. We demonstrate a safe and successful approach to resolving a PAC knot around pacing leads of a cardiac resynchronization device. Case presentationA 63-year-old African American male with dilated cardiomyopathy and a cardiac resynchronization therapy (CRT) device for severe left ventricular systolic dysfunction required PAC insertion for hemodynamic management of acute heart failure. PAC insertion was complicated by catheter knotting around the pacing leads. The PAC was successfully retrieved using a transvenous technique. ConclusionFluoroscopy-guided insertion of PAC is advisable and preferred over blind insertion in patients with high risk of PAC entanglement. Learning objectiveTo highlight a potential complication of blind pulmonary artery catheter insertion and provide a safe technique to resolve catheter knots.
