Right atrial thrombosis, though rare, can mimic digestive issues. Early diagnosis via echocardiography and CT, followed by heparin therapy, successfully lysed the thrombus and prevented sudden death.
Area of Science:
- Cardiology
- Diagnostic Imaging
Background:
- Intracardiac masses are increasingly detected with advanced echocardiography.
- Right atrial thrombosis is a rare condition compared to left atrial thrombosis.
Observation:
- A patient presented with symptoms mimicking acute pancreatitis and mesenteric infarction.
- Digestive and cardiovascular signs were misleading.
- Imaging (echocardiography, CT) ruled out gastrointestinal causes.
Findings:
- A massive right atrial thrombus prolapsing through the tricuspid valve was identified.
- Elevated D-dimers and new right bundle branch block indicated right ventricular strain.
- Heparin therapy led to thrombus lysis within 36 hours.
Implications:
- Early diagnosis of right atrial thrombosis is crucial for preventing life-threatening complications.
- Prompt heparin treatment can effectively resolve the thrombus.
- Echocardiography and CT are vital for accurate diagnosis and management.
