RenalGuard Therapy(R) Shows Promise in TAVI Procedures

Data Presented at European Medical Conference

MILFORD, MA--(Healthcare Sales & Marketing Network) - PLC Systems Inc. (PLCSF), a company focused on innovative medical device technologies, today announced that Dr. Vaikom Mahadevan presented RenalGuard® data during the Interventions for Structure Heart Disease session at EuroPCR, the annual meeting of the European Association of Percutaneous Cardiovascular Interventions (EAPCI). The data presented supports the further development of RenalGuard Therapy® to minimize Acute Kidney Injury (AKI) in patients undergoing Transcatheter Aortic Valve Implantation (TAVI) procedures.

Dr. Vaikom Mahadevan, Consultant Cardiologist at Manchester Royal Infirmary, commented, "RenalGuard has performed very nicely in this difficult patient population. My experiences so far lead me to believe that RenalGuard can be used effectively as a treatment for TAVI patients with renal impairment to reduce the risk of renal function deterioration."

In his presentation titled, "Minimizing Acute Kidney Injury During TAVI Procedures," Dr. Mahadevan shared data from patients on RenalGuard during a TAVI procedure. The results showed that the RenalGuard Therapy can be used safely in patients undergoing TAVI using general anesthesia.

Acute Kidney Injury (AKI) is a significant complication of TAVI, a minimally invasive procedure for replacing diseased aortic valves in patients that are not candidates for cardiac surgery. According to data published in EuroIntervention in 2012, the incidence of AKI after TAVI is very high. Numerous studies have shown that the development of AKI after TAVI leads to significantly worse long-term outcomes, including increased mortality after one year.

The therapy delivered by the RenalGuard system is based on the theory that creating and maintaining a high urine output can improve renal function. RenalGuard is intended to achieve high urine output safely by automatically and continuously measuring the patient's urine output and matching that volume by infusing an equal volume of hydration fluid. RenalGuard allows patients to receive as much fluid as they produce while minimizing the risk of over- or under-hydration. In two previously conducted studies, RenalGuard Therapy® has been shown to reduce the incidence of acute renal failure.
