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.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
