Acist launches high-definition IVUS


Acist Medical Systems showcased the first-ever high-definition intravascular ultrasound (HDi) system during two live cases at the Transcatheter Cardiovascular Therapeutics meeting (13–17 September, Washington, USA). The cases were presented from Medstar Washington Hospital Center (Washington, USA.) and New York-Presbyterian Hospital/Columbia University Medical Center (New York, USA).

According to a press release, the HDi features an intuitive touch screen with 60MHz image quality, high-speed pullback, a deliverable Kodama high definition-IVUS catheter and the ACIST HDi console. It adds that high definition IVUS is a reinvention of intravascular imaging.

“Improving patient outcomes by offering cardiologists innovative and improved tools is critical to our business,” said Tom Morizio, president and COO, Acist Medical Systems. “Our new high definition IVUS is a highly anticipated technology that offers improvements in an area that has lacked innovation for many years. Physicians tell us they appreciate that Acist is raising the bar for IVUS performance.”

The press release reports that the Acist HDi IVUS system is easier to use and offers detailed insight that physicians can use to optimize treatment choice for their patients. The HDi provides improved image quality over traditional IVUS systems. During one of the live broadcasts from Columbia Medical Center, world-renowned imaging expert Akiko Maehara noted, “The ability to visualise plaque morphologies and intravascular structures in high definition is a welcome advancement in imaging.”

Additionally, the press release notes, the simple, intuitive touch-screen display features 60MHz image quality, which enables easier identification and interpretation of intravascular structures and disease. The Kodama high definition-IVUS catheter is deliverable and offers high-speed pullback that is 20 times faster than currently available IVUS systems—lowering the risk of catheter-induced ischaemia by reducing pullback time from minutes to seconds.
