In 1956, Proudfit and Effler 1 reported a simple method of performing pericardial biopsy which provides adequate amounts of tissue for bacteriologic and histologic study. Safe and effective pericardial drainage can be accomplished by the same procedure.
Pericardial Window (Subxyphoid Pericardiostomy) is a minimally invasive procedure in which an opening is made in the pericardium to drain fluid that has accumulated around the heart. A pericardial window can be completed through a small incision below the end of the breastbone (sternum) or through a small incision between the ribs on the left side of the chest.
