Tenecteplase Versus Alteplase: A Comparison of Bleeding Outcomes in Massive Pulmonary Embolism (TACO-PE)

Thrombolysis is recommended in the setting of massive pulmonary embolism (PE) for reperfusion of vessels but carries a serious concern for increased bleed risk. In October 2022, our institution adopted tenecteplase as the formulary thrombolytic. Previous literature is unclear regarding the bleed risk of tenecteplase in massive PE, and no study has yet compared safety outcomes with the current standard of care, alteplase.
