EPIQ 5 Ultrasound System, EPIQ 5 systems with software versions 1.0.x or 1.1.x with QLAB a2DQ and/or aCMQ plug-ins are affected. Model: EPIQ 5G, EPIQ 5C, EPIQ 5W. Catalog Number: 795204 / 795205 and Part Number: 989605408541 Diagnostic Ultrasound Imaging.

Reason: When using the QLAB Auto 2D Quantification (a2DQ) and Auto Cardiac Motion Quantification (aCMQ) applications, the reported End-Systolic Volume (ESV) may be smaller, and the Left Ventricular Ejection Fraction (EF) may be higher, than the ESV and EF calculated by manual tracing without the use of QLAB. An incorrect EF calculation could lead to misdiagnosis and/or delayed or incorrect therapy.
