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.
A biopsy is a medical test commonly performed by a surgeon, interventional radiologist, or an interventional cardiologist involving extraction of sample cells or tissues for examination to determine the presence or extent of a disease. The tissue is generally examined under a microscope by a pathologist, and can also be analyzed chemically.
