New Studies in the U.S. and Europe Demonstrate LivaNova Perceval Valve’s Strong Performance and Economic Advantage in Aortic Disease Treatment
LivaNova PLC (NASDAQ:LIVN), a market-leading medical technology company, today announced the publication of three separate studies highlighting the unique performance of its sutureless aortic valve, Perceval®.
The results from the Perceval Aortic Heart Valve Study in North America, performed under a U.S. Food and Drug Administration (FDA) Investigational Device Exemption (IDE), were published in the Journal of Thoracic and Cardiovascular Surgery1. The study confirmed that Perceval achieves positive safety and efficacy outcomes whether or not an open or minimally invasive surgical approach is used. The multi-center, prospective, non-randomized, single-arm clinical trial included 300 patients from 18 U.S. centers.
The primary endpoints of this landmark study included safety (mortality and morbidity) and effectiveness (clinical status, hemodynamic performance and quality of life) at one year and highlighted positive outcomes for Perceval, including:
- Substantial functional improvement with 97.6% of patients in New York Heart Association (NYHA) class I/II after surgery.
- Significant improvement in quality of life metrics.
- Overall low hospital mortality (1.3%) and rate of ≥ moderate paravalvular leak (1.3%).
In addition, two separate articles were recently published and serve as further proof of the favorable economic profile of the Perceval valve.
The second article2 compares costs associated with the Perceval sutureless valve to those of traditional sutured valves. In the study at the Poliambulanza Hospital in Brescia, Italy, Perceval was assigned to patients at higher surgical risk, while a cohort of patients at lower surgical risk was treated with traditional sutured valves. Daily per patient costs were calculated and included preoperative tests, operating costs, disposables, drugs, blood components and personnel costs.
The results demonstrated that hospital costs excluding the prosthesis were similar in the two groups, despite the higher risk of complexity for the cases in the Perceval group. “Despite higher operative risks in the Perceval group, hospital mortality, morbidity and resource consumption did not differ,” said Dr. Giovanni Troise, Head Cardiac Surgeon at Poliambulanza Hospital. “Operating times were shorter with the sutureless device. This improvement, coupled with the increasing adoption of minimally invasive approaches, should further favor the Perceval valve’s market acceptance.”
The third article3 assessed the incremental cost-utility of surgical sutureless aortic valves compared to transcatheter aortic valves, for the treatment of intermediate- to high-risk patients in the U.S., Germany, France, Italy, UK and Australia. The cost-utility study relied on a meta-analysis comparing efficacy and safety outcomes. The study analyzed more than 1,400 patients treated with either surgical sutureless valves (95% of which were Perceval patients) or transcatheter aortic valves. A simulation estimated the long-term consequences following patient discharge from hospital.
Due to lower in-hospital and overall mortality rates, the study showed that patients treated with Perceval are expected to live an average of 1.14 quality-adjusted life-years (QALYs) greater than those treated with a transcatheter aortic valve.
Lifetime cost savings were reported across the board in all geographies under analysis. “These relevant findings acknowledge the clinical and economic relevance of adding sutureless valves as an integral part of your Structural Heart program,” said Dr. Mattia Glauber, Head Cardiac Surgeon at Istituto Clinico Sant’Ambrogio in Milan, Italy. “Our institution performs Perceval implantations on a routine basis via right anterior thoracotomy - the ultimate minimally invasive surgical procedure. This approach generates clear patient benefits, economic advantages and represents an ideal complement to transcatheter aortic valves in the appropriate patient risk category.”
“These three publications add to the already significant body of evidence available on Perceval,” said Alistair Simpson, LivaNova General Manager of Cardiac Surgery. “We are delighted to see the positive clinical results generated by Perceval, and to read that our unique valve is being recognized as a financially viable option for the treatment of aortic valve diseases. Achieving cost reductions while improving outcomes is of paramount importance to healthcare systems worldwide. We are proud to see that Perceval is helping realize both.”

Important Safety Information
EUROPE: The Perceval prosthesis is indicated for the replacement of diseased native or a malfunctioning prosthetic aortic valve via open heart surgery. The prosthesis is indicated for use in adult patients who are diagnosed to have aortic valve stenosis or steno-insufficiency.
USA: The Perceval bioprosthesis is indicated for the replacement of diseased, damaged or malfunctioning native or prosthetic aortic valves.
CANADA: The Perceval S bioprosthesis is intended for use in patients aged ≥ 65 years when the aortic valve pathology is in an advanced stage to require the replacement of the native or malfunctioning previously implanted prosthesis.
AUSTRALIA: Perceval S prosthesis is indicated for the replacement of a diseased native or a malfunctioning prosthetic aortic valve via open heart surgery. The prosthesis is indicated in patients who meet the following criteria: 1) subjects of age ≥ 65 years 2) subjects with aortic valve stenosis or steno-insufficiency.
TOP POTENTIAL SIDE EFFECTS
The risks or potential adverse events associated with cardiac valve replacement with a bioprosthesis include, but may not be limited to: cardiac arrhythmias, death, endocarditis, heart failure, hemorrhage, intravalvular and/or paravalvular leak, stroke or any related neurologic disorders, structural valve deterioration, reoperation and explant. Beyond the previously mentioned adverse events, specific events related to the implant of the Perceval prosthesis may include, but not be limited to dislodgment and/or migration of the prosthesis.
