Pulmonary embolism in infective endocarditis associated with pacemaker: report of a case and review of the literature



infective endocarditis, pacemaker, catheter, percutaneous extraction, pulmonary embolism



One of the most feared infective endocarditis (IE) complications associated with pacemaker is pulmonary embolism. We present the case of a patient with a current diagnosis of pacemaker-associated IE who presented symptoms of pulmonary embolism confirmed by imaging studies after percutaneous removal of the device.


to know the management and evolution, in-hospital and at 18 months of pulmonary embolism in the context of infective endocarditis associated with pacemaker.

Bibliographic search carried out in PubMed. Clinical case report: clinical evaluation, presentation of complementary studies, and treatment. Follow up on the case.


68-year-old patient with a history of dual chamber permanent pacemaker implantation 2 years ago. Prolonged febrile syndrome with no apparent focus, with positive blood cultures for methicillin-resistant Staphylococcus aureus. The transesophageal echocardiogram showed multiple vegetations associated in right atrial with the catheters. Based on the history, physical examination, and findings in specific tests, the diagnosis of IE associated with DEIP could be achieved. Antibiotic treatment and complete percutaneous removal of the device were indicated. After the procedure, he presented sudden dyspnea, confirming the diagnosis of pulmonary embolism in a ventilation-perfusion scintigram study. She completed the antibiotic treatment (vancomycin for 6 weeks) and was discharged. During follow-up, there were no new infections or other complications.


in our patient pulmonary embolism did not generate changes in in-hospital morbidity and mortality or in the 18-month follow-up.
