Pre-Implant Form
LVEF% Left ventricular ejection fraction. If a number or range is available,
check the number range that best applies. E.g. 30-35 would be entered as 30-
40. Occasionally the LVEF may be described only as “left ventricular function” or
“systolic function” in words. “Mild impairment, mildly reduced, or mild decrease”
would all be characterized as “mild”.
> 50 (normal)
40-49 (mild)
30-39 (moderate)
20-29 (moderate/severe)
< 20 (severe)
Not Recorded or Not Documented
LVEDD: Left ventricular end-diastolic dimension in centimeters.
ST= Not Recorded or Not Documented
RV Function: Is generally NOT measured in numbers, as it is difficult to quantify.
It may be described as “right ventricular function” or “right ventricular
contractility”. “Mild impairment, mildly reduced, or mild decrease” would all be
characterized as “mild”. Again, mild-moderate would be recorded as moderate,
and moderate-severe would be recorded as “severe”.
Swan Hemodynamics - closest to implant but not in OR
Pulmonary artery systolic pressure: This may be abbreviated PAS or
pulmonary pressures. mmHg (millimeters of mercury).
ST= Unknown or Not Done.
Pulmonary artery diastolic pressure: This may be abbreviated PAD or
pulmonary pressures. mmHg (millimeters of mercury).
ST= Unknown or Not Done.
Mean RA Pressure: May be listed also as RAP or CVP. ST= Unknown or Not
Done.
Central venous pressure (CVP): _____ mmHg ST= Unknown or Not Done
Mean Pulmonary artery wedge pressure: May be listed also as PCW or
pulmonary capillary wedge pressure. It is not always provided in the
hemodynamic data. ST= Unknown or Not Done.
Cardiac output: Will be expressed as Liters/min or L/min. Enter this number.
The cardiac index is NOT what we want; it is a smaller number expressed as
Liters/min/m 2 or L/min/m 2. ST= Unknown or Not Done.
