Velocity Vector Ultrasound

It provides more comprehensive cardiac contraction and motion data with the possibility to evaluate cardiac anatomy in patients with congestive heart failure, dyssynchrony, and other myocardial function disorders.

Velocity vector aiming is intended for use with any transducer for all cardiovascular aiming including pediatrics, adult, transesophageal (TEE), intracardiac echocardiography, vascular, and fetal applications.

Siemens Medical Solutions (Erlangen, Germany) introduced this new technology with the release of the Acuson Sequoia echocardiogram platforms, accompanied by the presentation of the Acuson AcuNav 8F ultrasound catheter at the annual congress of the European Society of Cardiology, held in Stockholm (Sweden) in September 2005.

The AcuNav 8F is 33% smaller in the cross-sectional region than the existing AcuNav 10F catheter and enables improved assessment in all patients, especially smaller patients, and for left heart applications in electrophysiologic and interventional cardiology. "The trend in cardiac procedures is toward less-invasive surgery, going from open surgery to keyhole access, and now to catheter-based procedures, which demand new visualization techniques,” stated Klaus Hambuchen, head of the ultrasound division at Siemens.

The 8F catheter will soon be available in the European Union countries for use with the Acuson Sequoia, the Acuson CV70, and the Acuson Cypress cardiovascular systems.
