Stepwise surgical approach to left ventricular fibroma

Area of Science:

• Cardiology
• Pediatric Oncology
• Cardiac Surgery

Background:

• Cardiac fibromas are rare benign myocardial tumors, predominantly affecting infants and children.
• Adolescent presentations are infrequent but carry significant risks, primarily related to cardiac arrhythmias.

Purpose of the Study:

• To report a case of a young female diagnosed with a left ventricular fibroma.
• To demonstrate the surgical approach for excising a left ventricular fibroma, focusing on mitral valve preservation.

Main Methods:

• Diagnosis was confirmed using cardiac magnetic resonance imaging (MRI).
• Surgical excision was performed via left ventriculotomy, with meticulous attention to avoiding mitral valve distortion.

Main Results:

• A left ventricular fibroma was successfully diagnosed and surgically removed.
• The surgical technique prioritized the preservation of mitral valve function.

Conclusions:

• Surgical excision is a definitive treatment for left ventricular fibromas, effectively mitigating arrhythmogenic risks.
• This approach aims to resolve life-threatening arrhythmia risks while maintaining valve integrity.
