  Mannequin Sizing Guidelines
  The Mannequin is available in 9 sizes ranging from 80 cc to 150 cc.

Selection of Mannequin size is determined by multiplying Body Surface Area (BSA) by a conversion factor of 50 to 80 mililiters per square meter.* The degree of dilation present in the basal portion of the left ventricle pre-operatively determines the conversion factor to be used.

The following guidelines may assist the clinical team in selecting the appropriate Mannequin size for each individual patient.

  1. Determine Body Surface Area (BSA).
  2. Assess the degree of dilation present in the base of the left ventricle at end-diastole. Measure above papilary muscles and below mitral valve.
  3. Use the following guidelines to calculate Mannequin size
