Auto text: “Insert Prosthetic Valve”
- Identify the type of prosthesis and measure the external diameter of the outside sewing ring. Commonly used valves are the Hancock porcine and St. Jude prosthetic (bi-leaflet valve).
- Describe any tissue overgrowth of the sewing ring.
- For mechanical valves, note any asymmetry, notches, cracks or impairment in the motion of the components.
- For tissue valves, note any tears or perforations of the cusps or any impairment of cusp motion.
- Describe any vegetations, including color, site (surface of valve, sewing ring), size, consistency (firm, friable), and destruction of underlying material.
- Note calcific deposits and their locations.
- For tissue valves, submit a portion of the cusps. For prosthetic valves, submit tissue on the sewing ring adjacent to the valve. In cases of suspected endocarditis, order Gram and GMS stains in advance.
