Results of a feasibility study indicate that measures of trans-stenotic pressure gradients can be safely and effectively obtained in intracranial large arteries through the use of a guidewire. Use of ...

However, when V 1 is greater than 1 m/s, which may be seen in concomitant AR or a high output state, it should be included in the formula. The mean pressure gradient is derived from the average ...

Pressure tracings made from the body of the left ventricle (LV) (A), the body and left ventricular outflow tract (LVOT) (B), and LV body and aorta (C). In B, both catheters record an LV pressure ...

August 16, 2013. Agilent Technologies Inc. has announced a new agreement that expands its business relationship with Gradient Design Automation, a provider of electro-thermal simulation technology ...
