The new Prime edition of Siemens’ Acuson SC2000 ultrasound system is the first to offer live full-volume color Doppler imaging of heart valve anatomy and blood-flow using a new true volume transesophageal echo (TEE) probe. With this technology, physicians can obtain a more anatomically authentic view of the heart and dynamic blood flow in one view during interventional valve procedures, even in patients with ECG abnormalities. During 3D TEE imaging, the physician guides a flexible probe into the esophagus to acquire close-range, detailed pictures of the heart to assess valve function. When a dysfunctional valve leaks blood back into the heart chambers or does not open properly to let through sufficient blood, a valve procedure may be necessary to repair or replace the valve with an artificial one. TEE is used to guide placement of devices such as mitraclips and artificial valves during cardiac interventions to correct valve dysfunction. Current methods of imaging with 3D TEE require stitching – the fusion of multiple heartbeats – to form a complete image of heart function and blood flow. This gated acquisition eliminates almost all patients with any ECG abnormalities and often results in image artifacts, which may skew results. However, the new Z6Ms true volume TEE probe enables full 3D images of the heart, in every heartbeat without stitching. By eliminating the need for multiple beats to form an image and adding volume color Doppler capabilities, the Z6Ms true volume TEE probe allows the surgeon to visualize and assess blood flow in real-time during a procedure to make sure the repaired or replaced valve is working properly, potentially reducing the need for a secondary intervention to correct any remaining regurgitation. This quantitative information allows physicians to quickly and easily evaluate valvular anatomy and physiology, which aids in device sizing and surgical repair. The new PRIME technologies including the Z6Ms true volume TEE transducer and the eSie Valves package are also available as an upgrade for users of previous versions of the Acuson SC2000 system.
