Siemens Gains FDA Clearance of Acuson SC2000 Prime Ultrasound System.

October 21, 2014 — Siemens Healthcare has announced that the U.S. Food and Drug Administration (FDA) has cleared the new Prime edition of its Acuson SC2000 premium cardiovascular imaging system — a system that offers 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 accurate view of the heart and dynamic blood flow in one view during interventional valve procedures, even in patients with electrocardiogram (ECG) abnormalities. This information helps physicians make faster, more accurate critical decisions.

During 3-D TEE imaging, the physician guides a flexible probe into the esophagus to acquire close-range, detailed cardiac images to assess valve function. TEE helps guide placement of devices such as MitraClips and artificial valves during cardiac interventions to correct valve dysfunction.

Current 3-D TEE imaging methods require stitching — the fusion of multiple heartbeats — to form a complete image of cardiac function and blood flow. This gated acquisition eliminates almost all patients with any ECG abnormalities and often results in image artifacts that 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 3-D TEE with 90° x 90° real-time acquisition and full-volume color Doppler, enabling complete 3D images of the heart, in every heartbeat. 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 ensure proper function of the repaired or replaced valve, potentially reducing the need for a secondary intervention to correct any remaining regurgitation or the leakage of blood back into the heart chambers due to a dysfunctional valve.

“Volume color Doppler is extremely important,” says Lissa Sugeng, M.D., associate professor of medicine at Yale University, New Haven, Conn. “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 on the Acuson SC2000 Prime is the eSie Valves advanced analysis semi-automated software package, which measures heart valves during cardiac procedures. While standard quantification software requires several minutes to provide heart valve measurements, eSie Valves provides semi-automated aortic and mitral valve measurements in seconds. This quantitative information allows physicians to quickly and easily evaluate valvular anatomy and physiology, which aids in device sizing and surgical repair.

Siemens’ new Prime cardiovascular ultrasound 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.

A 3-D ultrasound system provides an effective, noninvasive way to estimate blood flow that retains its accuracy across different equipment, operators and facilities, according to a study published in the journal Radiology.

Volume flow as a function of color flow gain (at a single testing site). For each row the color flow c-plane and the computed volume flow are shown as a function of color flow gain. The c-plane is shown for four representative gain levels, whereas the computed volume flow is shown for 12–17 steps across the available gain settings. Flow was computed with (solid circles on the graphs) and without (hollow circles on the graphs) partial volume correction. Partial volume correction accounts for pixels that are only partially inside the lumen. Therefore, high gain (ie, blooming) does not result in overestimation of flow. Systems 1 and 2 converge to true flow after the lumen is filled with color pixel. System 3 is nearly constant regarding gain and underestimates the flow by approximately 17%. Shown are mean flow estimated from 20 volumes, and the error bars show standard deviation. Image courtesy of the journal Radiology

Although it is likely that existing ultrasound systems will be repurposed to treat COVID-19 patients, growth is still expected as companies plan to ramp up production. The ultrasound systems market will therefore outpace other diagnostic imaging such as computed tomography (CT) and magnetic resonance imaging (MRI). Leading data and analytics company GlobalData forecasts the market will reach $6bn by 2028, but increased usage due to COVID-19 is anticipated have a tangible effect.
