Results of the PARTNER Trial Cohort A cost effectiveness analysis reported

11.11.2011
New analysis measures cost effectiveness of transcatheter aortic valve replacement compared to surgical valve replacement

The cost effectiveness of transcatheter aortic valve implantation (TAVR) compared to surgical aortic valve replacement (SAVR) depends on whether TAVR is performed via the femoral artery or transapically, through a small incision in the chest, according to a new study.

Recently, transcatheter aortic valve implantation (TAVR) has been shown to result in similar 12-month survival as surgical aortic valve replacement (SAVR) for high-risk patients with severe aortic stenosis. The potential cost-effectiveness of TAVR versus SAVR in the PARTNER trial was examined and the results were presented today at the 23rd annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, sponsored by the Cardiovascular Research Foundation.

The PARTNER trial randomized patients with severe, symptomatic aortic stenosis and high surgical risk to either TAVR (N=348) or SAVR (N=351) and followed them for a minimum of 12 months. Health state utilities were estimated using the EuroQOL (EQ-5D) at baseline, one, six, and 12 months. Detailed medical resource utilization data were collected on all study patients, and hospital billing data were collected for both index and follow-up hospitalizations for any cause from consenting U.S. patients.

The objectives of the study were to combine cost data with survival and Quality of Life (QoL) data to estimate the12-month cost-effectiveness of TAVR compared with AVR and to explore potential differences in costs and cost-effectiveness of TAVR vs. AVR for the transfemoral vs. transapical populations.

Among high risk aortic stenosis patients eligible for the transfemoral approach, TAVR, compared with surgical AVR:

Provided small but significant gains in 12 month quality-adjusted life expectancy (0.06 – 0.07 Quality Adjusted Life Years, QALYs)

Was associated with higher procedural costs but slightly lower index hospitalization and total 12 month costs

However, not all patients qualify medically for the transfemoral approach. Among patients only eligible for the transapical approach:

TAVR provided no increase (and possible decrease) in QALYs
TAVR increased procedural, index admission, and 12 month costs (by ~$10,000/patient)

"Results of this trial indicate that for patients with severe aortic stenosis and high surgical risk, transcatheter aortic valve replacement is an economically attractive and possibly dominant strategy compared with surgical aortic valve replacement, provided that patients are suitable for the transfemoral approach," said Matthew R. Reynolds, MD. Dr. Reynolds is Director of the Economics and Quality of Life Research Center at Harvard Clinical Research Institute (HCRI), an Assistant Professor of Medicine at Harvard Medical School and Associate Director of Electrophysiology at the Boston VA Health Care System.

"Current results for transcatheter aortic valve replacement via the transapical approach, compared with surgical aortic valve replacement, are unattractive from a health economic perspective," said Dr. Reynolds.

"Whether the transapical approach can be refined to provide faster recovery and better results from a cost perspective should be the subject of further study."

The PARTNER trial is funded by a research grant from Edwards Lifesciences, Inc. Dr. Reynolds reported that his research organization (HCRI) receives research grant support from the company.

About CRF and TCT

The Cardiovascular Research Foundation (CRF) is an independent, academically focused nonprofit organization dedicated to improving the survival and quality of life for people with cardiovascular disease through research and education. Since its inception in 1991, CRF has played a major role in realizing dramatic improvements in the lives of countless numbers of patients by establishing the safe use of new technologies, drugs and therapies in interventional cardiovascular medicine.

Transcatheter Cardiovascular Therapeutics (TCT) is the annual scientific symposium of the Cardiovascular Research Foundation. TCT gathers leading medical researchers and clinicians from around the world to present and discuss the latest developments in the field.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
