Recommended management includes IV alteplase for high\u2010risk PE. However, evidence guiding higher thrombolytic doses during cardiac arrest remains limited and is rarely reported. We present a case of massive PE requiring an atypically high cumulative tPA dose administered during CPR, resulting in return of spontaneous circulation (ROSC).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case Description<\/jats:title>\n                    <jats:p>A 38\u2010year\u2010old female with prior DVT and PE presented with syncope and left lower extremity edema. Imaging confirmed bilateral PE and DVT. She was found to be hemodynamically unstable and was treated with 100\u2009mg IV tPA. This resulted in transient improvement, but she subsequently suffered a prolonged PEA arrest. During ACLS, there was confirmation of cardiac standstill on POCUS. A second bolus of 50\u2009mg tPA was administered 29\u2009min into the code, which led to sustained ROSC within 2\u2009min. Despite maximal vasopressor and inotropic support, persistent shock and hypoxemia necessitated pulmonary angiography and attempted thrombectomy, which was aborted due to recurrent arrest. Catheter\u2010directed thrombolysis with bilateral EKOS catheters was initiated, and by ICU Day 3, echocardiography revealed normalized RV function.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>Massive PE causes acute RV failure and impaired pulmonary perfusion, which may limit thrombolytic delivery. Repeat tPA dosing during CPR may enhance clot penetration and improve outcomes. When systemic thrombolysis is insufficient, catheter\u2010directed therapies can provide additional hemodynamic benefit. Adjunctive strategies including ventilatory optimization, pulmonary vasodilation, and neuroprotection were critical for the patient to achieving full recovery.<\/jats:p>\n
