Subxiphoid video-pericardioscopy

Through a subxiphoid approach, the pericardium is incised and a rigid (usually a video-mediastinoscope) or a flexible endoscope (flexible bronchoscope or flexible choledoscope) is inserted into the pericardial cavity. The inner surface of the parietal pericardium and the epicardium can be explored and biopsies can be taken under visual control. In addition, a subxiphoid pericardial window can be developed, and sclerosing agents instilled for pericardiodesis, if a malignant aetiology is confirmed.
