In a revolutionary fashion, BDC Laboratories’ HDTi-6000 heart valve pulse duplicator achieves ISO 5840 performance assessments in a focused and efficient manner with the added capability of integrated high speed video to facilitate real-time visualization of the heart valve under test. The HDTi-6000 can accommodate up to 5 high speed cameras, all simultaneously documenting multiple test article views concurrent with pressure and flow waveforms. After each heart valve test, a variety of both waveform analyses and video image analyses are available to characterize the heart valve’s performance and leaflet kinematics. Included with the many unique system features is the ability to playback the high-speed video while synchronized to the pressure and flow waveforms to comprehensively assess the heart valve leaflet response at any particular point in the cardiac cycle.
The HDTi-6000 pulse duplicator can accommodate both surgical and transcatheter heart valves while being configured as either as a left heart simulator or right heart simulator to evaluate any valve position (i.e. aortic, mitral, pulmonary, tricuspid). Utilizing a novel linear clamp assembly, with no need to drain the system between samples, the HDTi facilitates exchange of the test article in minutes and significantly increases productivity. BDC’s proven PD-1100 pulsatile pump is the fluid driving source for the HDTi-6000 pulse duplicator system yielding high repeatability, reproducibility and dynamic configurability.
The accompanying Statys® HDTi control and monitoring software gives the user absolute control over the pulse duplicator excitation waveform, while seamlessly integrated all high-speed cameras for both live and post-test video review. The system data collection and analysis tools that are embedded in the software provide instantaneous measurement of the test valve parameters such as pressure drop, effective orifice area, regurgitant volume, and leakage rate.
