Question

Cardiac tumors in Paediatric Cardiology.

Hint:

Early detection and proper management of cardiac tumors in children can improve outcomes and reduce the risk of complications.

Answer 1

Cardiac tumors in pediatric patients are rare but can cause significant morbidity and mortality if not diagnosed and treated appropriately. The majority of cardiac tumors in children are benign, with a small percentage being malignant.
Step 1: Types of Cardiac Tumors in Pediatrics:
1. Rhabdomyomas: These are the most common primary cardiac tumors in children, often associated with tuberous sclerosis. They are usually benign and tend to regress over time.
2. Fibromas: These tumors are the second most common type and are often found in the ventricular myocardium. They can cause obstruction or arrhythmias.
3. Teratomas and Myxomas: These are less common and can be benign or malignant. Myxomas, though rare in children, can present with obstruction and embolic phenomena.
4. Malignant Tumors: These include sarcomas, which are aggressive and may present with heart failure, arrhythmias, or embolic events.
Step 2: Diagnosis:
1. Echocardiography: This is the primary diagnostic tool, allowing for the visualization of tumors, their location, and size.
2. Magnetic Resonance Imaging (MRI): MRI provides detailed information regarding the tumor's tissue characteristics and its relationship to adjacent structures.
3. CT Scan: CT scans are sometimes used to evaluate the extent of the tumor or to guide surgery.
4. Biopsy: In some cases, a biopsy is required to confirm the diagnosis, especially for malignant tumors.
Step 3: Treatment:
1. Surgical Resection: The primary treatment for symptomatic tumors or those causing obstruction is surgical removal.
2. Observation: Many benign tumors, such as rhabdomyomas, may be monitored over time, especially if they are asymptomatic.
3. Chemotherapy and Radiation: These may be required for malignant tumors or those that cannot be completely removed.
