[Thrombus in transit and submassive pulmonary thromboembolism succesfully treated with tenecteplase]. / Trombo en tránsito y tromboembolia pulmonar (TEP) submasiva tratados exitosamente con tenecteplasa (TNK).

Right heart thrombus is a slightly detectable condition. In patients presenting with acute pulmonary embolism, the finding of thrombus in transit has been associated with high in-hospital mortality. We present a case of a 50-year-old male patient with acute pulmonary embolism and a thrombus in transit in the right atrium. We took the decision to perform fibrinolysis with tenecteplase, presenting significant improvement in the clinical condition, without any complications related to the therapy. Our case demonstrates the effectiveness of thrombolytic therapy in cases of pulmonary embolism and thrombus in transit in right chambers.
