How do you biopsy nodes around the heart?

Biopsy of nodes around the heart, typically referring to mediastinal or pericardial lymph nodes, can be performed using minimally invasive techniques such as mediastinoscopy or endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration. These procedures involve using a camera and specialized instruments to access the lymph nodes through small incisions or the bronchial tubes. Imaging guidance, such as CT or ultrasound, may be employed to ensure accurate targeting of the nodes. It's essential to follow protocols for patient safety and to obtain adequate tissue samples for histological analysis.
