New Siemens ultrasound system visualizes entire blood flow during valve procedures

29.08.2014
  • 3D transesophageal probe enables true volume color Doppler visualization of blood flow during interventional procedures
  • New automated valve analysis software delivers comprehensive valve measurements within seconds to support heart interventions

Acuson SC2000 Prime Edition 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.

Siemens Healthcare introduces the new Prime edition of its Acuson SC2000 ultrasound system at the annual congress of the European Society of Cardiology (ESC). This new release of the premium cardiovascular imaging 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. This helps them to make faster and more accurate critical decisions.

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 (known as regurgitation) 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 on the Acuson SC2000 Prime is the first Siemens transducer to use true volume 3D TEE with 90° x 90° real-time acquisition and volume color Doppler, enabling 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.

"Volume color Doppler is extremely important," says Dr. Lissa Sugeng, Associate Professor of Medicine at Yale University. "With Siemens' new volume acquisition, I can see the entire valve, locate the regurgitant jet, and assess the size of the orifice very quickly so that we can continue with the procedure."

Also introduced for the first time on the Acuson SC2000 Prime is eSie Valves advanced analysis package, an automated software to measure heart valves during cardiac procedures. While standard quantification software takes several minutes to provide measurements of heart valves, eSie Valves provides automated measurements for the aortic and mitral valves in seconds1. This quantitative information allows physicians to quickly and easily evaluate valvular anatomy and physiology, which aids in device sizing and surgical repair.

"We're extremely proud of what the Acuson SC2000 Prime enables physicians to do in the detection and treatment of valvular disease," says Dr. Jeffrey Bundy, CEO, Siemens Ultrasound. "We are aiming to provide tools with standard-setting performance and workflow, equipping physicians to focus on their patients and explore new and more efficacious procedures."

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.
