Summary
A rare transseptal thrombus straddling the patent foramen ovale (TSFO) was identified using CT angiography in an elderly woman with acute dyspnea. Early anticoagulation prevented further embolic events, demonstrating the value of prompt diagnosis.
Area of Science:
- Cardiology
- Radiology
- Vascular Medicine
Background:
- A transseptal thrombus straddling the patent foramen ovale (TSFO) is a rare but serious finding.
- It is often indicative of paradoxical embolism, requiring urgent recognition.
- The dynamic nature of TSFO makes timely diagnosis challenging.

01:30Venous Thrombosis I: Introduction
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
