Cardiac Surgery Associated-Acute Kidney Injury (CSA-AKI)

Renal Insufficiency Meets Stress

Patients with renal insufficiency undergoing cardiac surgery are at significant risk for developing CSA-AKI.1-5

Renal Insufficiency

Surgical Stressors

Increased CSA-AKI Risk

Renal Insufficiency 

Renal Insufficiency
20 %
of cardiac surgery patients have renal insufficiency1-4

Compromised kidney function

A quarter of all cardiac surgery patients have compromised kidney function.1-4
eGFR < 60
(mL/min/1.73m2)

Surgical Stressors

Surgical Stressors
95 %
of cardiac surgery patients experience renal stressors

Insults on the kidneys

Cardiac surgery is especially taxing for the kidneys of patients with renal insufficiency due to:

Increased CSA-AKI Risk

Poor Outcomes
up to 34 %
of cardiac surgery patients with pre-existing CKD develop AKI5

When the kidneys fail, the patient fails.

Acute kidney injury (AKI) in patients with renal insufficiency has a significant impact:

2 x
increase in cost of care5-8
5 x
risk of extended hospital stay9,10
7 x
operative mortality rate9
55 x
likelihood of dialysis*9

*When patients with a normal eGFR (>90) are compared to CKD 4 (<30) patients the incidence of new requirement for dialysis is 0.2% to 10.9%; 55x.

The JuxtaFlow® Renal Assist Device (RAD)

Roivios is developing a first-of-its-kind treatment designed to prevent AKI in patients undergoing cardiac surgery with pre-existing renal insufficiency.
