    Retained clots post-pulmonary embolism (PE) significantly increase early mortality risk, reaching 17% within three months.

  • 2

    Current guidelines restrict catheter-directed interventions to hemodynamically unstable and intermediate-high-risk PE patients.

  • 3

    Intermediate-low-risk PE patients with retained large venous clots may benefit from catheter-directed interventions to reduce RV afterload.

  • 4

    Studies indicate that retained venous thrombi are predictive of increased mortality in patients recovering from PE.

  • 5

    The authors propose modifying guidelines to include intermediate-low-risk patients for catheter-directed therapy based on retained clots.
