The impact of precise robotic lesion length measurement on stent length selection: Ramifications for stent savings

Current and Future Use of Robotic Devices to Perform Percutaneous Coronary Interventions: A Review

“…In a recent study of 40 interventional cardiologists, visual lesion length was underestimated by 51% and overestimated by 19% . Similar numbers were shown when compared with objective robotic measurement . Although this information needs to be confirmed with prospective clinical data, by improving accuracy of lesion‐length assessment, robot‐assisted PCI hold the potential to reduce the risk of in‐stent restenosis and to improve patient outcomes .…”

“…In their study, visual estimates of lesion length and stent selection by treating physicians were compared with measurements made using the robotic system. The study showed that, compared with robotic measurement, only 35% of visually estimated lesions resulted in accurate stent selection, whereas 33% of stents were long (25±13 versus 18±11, P =0.002) and 32% were short (20±9 versus 23±11, P <0.001) …”

Robotic‐assisted percutaneous coronary intervention

“…Furthermore, as lesion measurement using the CorPath 200 is determined by guidewire movement during advancement, the process may be inaccurate in cases of increased resistance or guidewire bucking. In another study by Campbell et al, cardiologists performing robotic‐assisted PCI on a series of 60 patients were asked to estimate lesions length and ideal stent size prior to measuring lesions with the computer system . Only 35% of cardiologists accurately predicted lesion length, defined as accurate if within 1 mm of the computer‐assisted measurements using the robotic system.…”

“…Contrastingly, the cardiologists performing robotic-assisted PCI on a series of 60 patients were asked to estimate lesions length and ideal stent size prior to measuring lesions with the computer system [49]. Only 35% of cardiologists accurately predicted lesion length, defined as accurate if within 1 mm of the computer-assisted measurements using the robotic system.…”

The Development of Robotic Technology in Cardiac and Vascular Interventions

“…In addition to the occupational hazard reduction for the operator, using the robotic platform, operators can make precise lesion length measurements, allowing for the selection of appropriate-length stents 23. As a result, potentially a lower number of stents are utilized, and, by reducing longitudinal geographic mismatch, an improvement in longer-term revascularization rates might be seen 24…”
