Summary
This case study shows direct visualization of a paradoxical embolus crossing the foramen ovale, a rare cardiac event. Prompt anticoagulation resolved the thrombus, preventing further complications.
Area of Science:
- Cardiology
- Vascular Medicine
- Diagnostic Imaging
Background:
- A 67-year-old male with a history of stroke and right hemiparesis presented with acute dyspnea and cyanosis.
- Symptoms followed prolonged immobilization due to slipped disc surgery.
Observation:
- Echocardiography revealed right heart enlargement and a thrombus crossing the foramen ovale.
- Color Doppler indicated moderate tricuspid regurgitation.
- Pulmonary artery systolic pressure was estimated at 55 mm Hg.
Findings:
- The patient received immediate anticoagulation therapy with heparin and warfarin.
- Follow-up echocardiography before discharge showed complete resolution of the thrombus.
- Pulmonary artery systolic pressure decreased to 40 mm Hg.
Implications:
- This case highlights the rare direct visualization of an impending paradoxical embolus.
- Early diagnosis and anticoagulation are crucial for managing such critical events.
- The findings underscore the importance of echocardiography in identifying intracardiac shunts and thrombi.
