Mannequin Sizing Guidelines

SURGICAL VENTRICULAR RESTORATION Procedure

Selection of Mannequin^TM size

Selection of Mannequin^TM size is determined by multiplying body surface area by a conversion factor of 50 to 60 milliliters per square meter.* The degree of dilatation 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.

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

If the base of the left ventricle is ...	Use this conversion factor ...
Non-dilated	BSA x 50 ml/m²
Moderately dilated	BSA x 55 ml/m²
Grossly dilated (tenting of mitral valve present)	BSA x 60 ml/m²

Note: If diameter of LV base at end-diastole is greater than 55 mm, use 60 ml/m² conversion factor.
