A rare complication of cardiovascular surgery, retained surgical foreign bodies can cause serious issues. This case highlights a cystic heart image in a child due to an iatrogenic foreign body, leading to cyanosis and dyspnea.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Medical Imaging
Background:
- Unintentional retained surgical foreign bodies are a known complication in cardiovascular procedures.
- Complications in pediatric patients are less frequently documented than in adults.
- Previous cardiac surgery for patent ductus arteriosus and aortic stenosis can be a precursor.
Observation:
- A 14-year-old girl presented with cyanosis and dyspnea.
- Imaging revealed a cystic heart image.
- The image was associated with a cardiac iatrogenic foreign body.
Findings:
- The iatrogenic foreign body was linked to a prior surgery 13 years ago.
- The foreign body resulted in a cystic cardiac mass.
- The patient's symptoms of cyanosis and dyspnea were attributed to this complication.
Implications:
- This case underscores the importance of vigilance for retained surgical materials, even years after procedures.
- It highlights the potential for delayed and serious complications in pediatric cardiovascular surgery.
- Accurate diagnosis and management are crucial for improving outcomes in such rare pediatric cases.

Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
