Rapid dissolution of right atrial thrombus in a patient with congestive cardiomyopathy
Insights
A large right atrial thrombus in a patient with alcoholic cardiomyopathy dissolved completely with anticoagulant therapy alone. This suggests anticoagulation may be a viable treatment option for similar intracardiac masses.
Area of Science:
- Cardiology
- Cardiovascular Medicine
- Thrombosis Research
Background:
- Congestive cardiomyopathy, particularly alcoholic cardiomyopathy, can present with complex cardiac conditions.
- Intracardiac masses, such as atrial thrombi, pose significant clinical challenges and risks.
- Right atrial thrombi can mimic other cardiac pathologies, necessitating accurate diagnosis.
Observation:
- A patient with probable alcoholic cardiomyopathy presented with congestive heart failure and a pericardial rub.
- Diagnostic imaging revealed a significant right atrial thrombus measuring 4 x 2 cm.
- The patient exhibited clinical signs and symptoms consistent with heart failure.
Findings:
- The right atrial thrombus demonstrated complete dissolution after 14 days of oral anticoagulant therapy.
- The patient's congestive heart failure symptoms and pericardial rub significantly decreased following anticoagulation.
- No signs of pulmonary embolism were noted in the patient.
Implications:
- Oral anticoagulant therapy may be an effective primary treatment for intracardiac masses in specific patient populations.
- Consideration of anticoagulant therapy prior to surgical intervention is recommended for intracardiac masses without pulmonary embolism in cardiomyopathy patients.
- This case highlights the potential for non-surgical management of right atrial thrombi in the context of cardiomyopathy.
Abstract:
The AA describe a patient with congestive cardiomyopathy, probably alcoholic, who exhibited signs and symptoms of congestive heart failure and a pericardial rub, due to a right atrial thrombus (4 X 2 cm). The thrombus dissolved completely and the symptoms decreased markedly after 14 days of oral anticoagulant therapy alone. We suggest that anticoagulant therapy should be considered before surgery, if an intracardiac mass with no signs of pulmonary embolism is found in a patient with cardiomyopathy.
