Summary
Cardiac hamartomas, rare benign heart tumors, can cause arrhythmias. This case highlights successful surgical removal of a left ventricular hamartoma, resolving tachycardia and ensuring long-term patient recovery.
Area of Science:
- Cardiology
- Cardiac Pathology
- Electrophysiology
Background:
- Cardiac hamartomas are uncommon benign cardiac neoplasms.
- Wide complex tachycardia can be a presenting symptom of cardiac masses.
- Early diagnosis and intervention are crucial for managing cardiac tumors.
Observation:
- A 33-year-old patient presented with wide complex tachycardia.
- Diagnostic imaging identified a cardiac mass in the left ventricular wall.
- The mass was surgically excised for diagnosis and treatment.
Findings:
- Pathological analysis confirmed the mass as a cardiac hamartoma composed of mature cardiac myocytes.
- Surgical resection effectively resolved the patient's tachycardia.
- Postoperative electrophysiology studies revealed no inducible arrhythmias.
Implications:
- This case demonstrates the successful management of a symptomatic cardiac hamartoma.
- Surgical resection is a viable treatment option for cardiac hamartomas causing arrhythmias.
- Long-term follow-up confirms a positive prognosis after complete tumor removal.
