Percutaneous left atrial cardiac biopsy with CT fluoroscopy guidance

Area of Science:

• Cardiology
• Oncology
• Radiology

Background:

• Intracardiac tumors require accurate diagnosis for effective treatment.
• Minimally invasive biopsy methods are sought to reduce procedural risks.

Observation:

• A 72-year-old woman presented with an intracardiac tumor in the left atrium.
• Percutaneous computed tomographic (CT) fluoroscopy-guided biopsy was performed.

Findings:

• The biopsy was technically successful and without immediate complications.
• Histopathology confirmed a high-grade cardiac sarcoma, necessitating resection and radiation therapy.

Implications:

• Percutaneous CT-guided biopsy can be a viable, minimally invasive option for diagnosing cardiac tumors.
• This approach may be particularly suitable for broad-based, luminal, or infiltrating tumors.
• Careful patient selection is crucial given the inherent risks of cardiac puncture.
