Insights
Transesophageal echocardiography revealed a pericardial effusion and a gap near an atrial septal defect occluder. This finding highlights potential complications following device closure of atrial septal defects.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Atrial septal defects (ASDs) are commonly closed using device occluders.
- Transesophageal echocardiography (TEE) is a key imaging modality for assessing cardiac structures and interventions.
Observation:
- A patient undergoing TEE presented with findings suggestive of complications post-ASD device closure.
Findings:
- TEE identified a pericardial effusion, indicating fluid accumulation around the heart.
- A notable gap was observed between the left atrium and the aortic sinus, adjacent to the implanted ASD occluder device.
Implications:
- This case underscores the importance of vigilant TEE monitoring for detecting potential complications after ASD device closure.
- The findings suggest a need to evaluate the integrity and positioning of ASD occluders to prevent adverse events like effusions.
Abstract:
Transesophageal echocardiography (TEE) shows pericardial effusion and a gap between the left atrium and the aortic sinus by atrial septal defect occluder.
