# To Lyse or Not: The Role of Half‐Dose Thrombolysis in Right Ventricular Clot Associated With Sub‐Massive Pulmonary Embolism

## TL;DR

A 43-year-old man with a rare heart clot and lung blockage successfully recovered using half the standard clot-dissolving treatment.

## Contribution

Demonstrates successful use of half-dose thrombolysis for right ventricular clot in sub-massive pulmonary embolism.

## Key findings

- Half-dose thrombolytic therapy resolved the right ventricular clot effectively.
- The patient showed no complications after treatment.
- The case suggests half-dose thrombolysis may be a viable treatment option.

## Abstract

Right heart thrombi are rare but carry a high mortality risk. Appropriate therapy remains unclear; options include anticoagulation, thrombolysis, and surgical thrombectomy. In this case, a 43‐year‐old male with DVT, RV thrombus, and bilateral pulmonary embolism responded well to half‐dose thrombolytic therapy, with complete thrombus resolution and no complications.
