LV Analysis

Clinically sourced functional and anatomical cardiovascular measurements in an easy-to-use tool.

The manual LV Analysis tool is widely adopted, having been available for well over 10 years across several different generations of Vevo Imaging Systems. Tracing measurements are available in B-Mode, M-Mode, and EKV Mode. The B-Mode / EKV Mode implementation adapts the clinically accepted modified Simpson’s monoplane method of disks approach for left ventricular analysis to small laboratory animals. These methodologies are discussed in the American Society Of Echocardiography consensus paper on Recommendations For Chamber Quantification¹. In M-Mode, wall thicknesses and chamber dimensions across the sample line are used to calculate anatomical and functional parameters.

Pressure-Volume Loops

The Vevo Imaging Systems and animal handling equipment can be integrated with a third-party blood pressure monitoring system.  Once connected and set up, blood pressure traces can then be displayed, and saved, as part of the physiological monitoring data. In conjunction with the LV Analysis tool, pressure-volume curves may be generated to determine pressure–volume relationships.
