The presence of external devices, such as intracardiac leads, could predispose to higher thrombotic risk in this setting. We present a clinical case of intracardiac thrombosis on right ventricle device that occurred after COVID-19 infection and subsequent vaccination.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Case summary<\/jats:title>\n                  <jats:p>A 56-year-old man, suffering from usual interstitial pneumonia-pattern fibrosis, was admitted to our hospital because of worsening of his clinical status. About 10 days earlier, he had got vaccinated for COVID-19. Three months earlier, the patient had been reported to have severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) infection. A chest computed tomography scan showed thrombus partially occluding the left pulmonary artery. A transthoracic echocardiography and later a transoesophageal echocardiogram showed a mass adhered to the lead in the right ventricle, compatible with thrombosis, confirmed on a cardiac computed tomography scan. Blood tests showed no major changes except for a slight increase in D-dimer and fibrinogen. Therefore, the subject was treated with anticoagulants.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>COVID-19 infection results in a hypercoagulable state with risk of developing thrombus diffusely, including intracardiac thrombosis. The presence of external devices, such as the intracardiac leads, may increase thrombotic risk since the presence of an external device in the bloodstream could trigger coagulation cascade. This case report highlights the need for special care in this patient setting, using specific imaging techniques for early and rapid diagnosis to optimize therapy.<\/jats:p>\n
