ACUSON Redwood 1.0 ultrasound displays incorrect cardiac measurement values
The ACUSON Redwood 1.0 Diagnostic Ultrasound System may display the last measured cardiac value instead of the minimum or maximum value as configured, potentially leading to misdiagnosis or improper patient management.
What this means for you
Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.
Our severity reasoning: This is a Class II medical device recall involving a software display error that could result in misdiagnosis or poor patient management decisions. No illnesses or injuries have been reported, making this a theoretical risk of harm rather than confirmed harm, which per the rubric places it at Score 3 (High).
Plain-English summary
The ACUSON Redwood 1.0 Diagnostic Ultrasound System (REF 11503314, software versions VA10A to VA10G) is subject to a recall due to a software display error in the Cardiac DICOM Structured Report feature.
When the Cardiac DICOM SR feature is configured to display either minimum or maximum measured cardiac values, and multiple measurements are made and exported, the SR viewer displays the last measured value instead of the configured minimum or maximum value. This could lead to clinicians reviewing incorrect data when making diagnostic or treatment decisions for cardiac patients.
Approximately 628 affected systems have been distributed worldwide, including throughout the United States and over 100 countries. Healthcare providers using these systems should contact Siemens Medical Solutions USA, Inc. for information about available software updates or corrective measures.
