Info

Manual Pullback • Advantages • Ability to concentrate on specific regions of interest by pausing the pullback at a specific location • Disadvantages • Can skip over pathology by pulling the transducer too quickly • No length or volume measurements • Antegrade and retrograde catheter movement can be confusing when study is reviewed at a later date • Impossible to pull transducer slowly and uniformly
Imaging Efficiency and Effectiveness • Perform imaging run(s), remove IVUS catheter, and make measurements from video tape or digital replay, NOT during live imaging • Less patient ischemia • More efficient use of cath lab time • Additional measurements can easily be made and additional questions easily answered • Display images on angiographic monitors • Superior monitors • Get IVUS system away from table • Requires separate roadmap or reference monitors
