REDUCE COMPLICATIONS RISK AFTER CARDIOVASCULAR INTERVENTIONS
PlanOp™ ERI
An Index ERI to assess the risk of type IA Endoleak following EVAR
At PrediSurge, we are dedicated to providing physicians with the best tools to reduce complications after cardiovascular interventions. Following this objective, we have created the Endoleak Risk Index (ERI), a cutting-edge technology designed to assess preoperatively the risk of Type IA endoleak associated with EVAR.
Why PlanOp™ ERI?
Assess complication risk
Endoleaks continue to affect around 30% of patient treated by EVAR. Of these, Type IA endoleaks are particularly challenging, as they are linked to a higher risk of rupture, ranging from 4% to 7.5% within two years post-intervention. * Thanks to PlanOp ERI, now you can assess complication risk before the intervention.

Anticipate clinical outcomes
Supporting physicians to better evaluate potential risk of complication is our mission. Based on patient-specific simulation of infrarenal stent-grafts implantation, PlanOpᵀᴹ ERI provides an assessment of type Ia Endoleak risk for standard EVAR.
This could lead physicians to:
- reduce the reintervention risk
- speed up and facilitate the cardiovascular procedure
- improving the procedure workflow
PlanOp™ ERI in action
ERI is an AI-powered index based on the analysis of the intervention simulation, with a specific focus on the proximal apposition between the endograft and the patient-specific aortic digital twin.
Improving procedure accuracy moving
from few data points to 16000
The digital twin technology enables hundreds of systematic measurements of the simulated endograft and aorta every 0.5 mm at the level of the proximal neck. Around 16 000 measurements are conducted for each simulation.
ERI, powered by artificial intelligence, has been designed to consolidate these measurements into a single index, evaluating the risk of type IA endoleak.
Scientific evidences

Study population:
Patients who underwent EVAR with standard and unfavourable anatomies.
Methods:
Simulation was performed using pre-op CT. Simulated stent-graft deployment was compared to post-op CT.
Results:
Relative radial deviations (between the simulation and post-operative CT) were 6.3 ± 4.4%.
Conclusion:
The numerical model predicted accurately stent-graft positions in the aortic neck.
About type IA endoleak risk
Endoleaks are the most frequent indications for secondary intervention after EVAR.
Type Ia endoleak, characterized by persistant blood flow between the endograft and the aortic wall at the proximal neck level, is the most common subtype of Type I endoleak.
Although risk factors for type IA endoleak have been established for many years, there has been a lack of efficient scoring system to assess this risk preoperatively.
