New study compares cost-effectiveness of transcatheter aortic valve replacement with surgical valve replacement in high risk patients

2014-09-15

(Press-News.org) WASHINGTON, DC – September 13, 2014 – According to a new study, transcatheter aortic valve replacement (TAVR) provided meaningful clinical benefits relative to surgical aortic valve replacement (SAVR) in high risk patients with incremental costs considered acceptable from a US perspective. Findings from the cost-effectiveness analysis of the US CoreValve High Risk Trial were reported today at the 26th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium. Sponsored by the Cardiovascular Research Foundation (CRF), TCT is the world's premier educational meeting specializing in interventional cardiovascular medicine.

Previous studies have shown that among patients with severe aortic stenosis who are unsuitable for conventional aortic valve surgery, TAVR provides substantial clinical benefits at a reasonable incremental cost. However, there has previously been less consensus about the cost effectiveness of TAVR relative to SAVR for high-risk surgical candidates.

Findings from the US CoreValve High Risk trial, published earlier this year in the New England Journal of Medicine, found that in patients with severe, symptomatic aortic stenosis who were deemed to be at high operative risk, TAVR using a self-expanding prosthesis was associated with lower 12-month mortality compared with SAVR (14.2 percent vs. 19.1 percent).

The cost-effectiveness analysis of the US CoreValve High Risk Trial compared the costs of TAVR and SAVR for this high risk population from the perspective of the US healthcare system. To assess cost effectiveness, inpatient and outpatient medical resource utilization was collected for all patients. Hospital bills were collected for 80 percent of the index hospital admissions and health state utilities were measured using the EQ-5D questionnaire at one, six and 12 months. The primary effectiveness measure was quality adjusted life years (QALY) and the secondary effectiveness measure was life years (LY).

In the as-treated population (n=747), the mean cost for the initial valve implant procedure was $23,661 higher per patient with TAVR than with SAVR ($37,920 vs. $14,258, respectively p END

Results of CLEAN-TAVI trial reported at TCT 2014

2014-09-15

WASHINGTON, DC – September 13, 2014 – A first-of-its kind study found that using a cerebral protection device during transcatheter aortic valve replacement (TAVR) can significantly reduce the number and volume of cerebral lesions in high risk patients with severe aortic stenosis. Findings were reported today at the 26th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium. Sponsored by the Cardiovascular Research Foundation (CRF), TCT is the world's premier educational meeting specializing in interventional cardiovascular medicine. Stroke remains ...

Two-year results of the CoreValve US Pivotal trial reported at TCT 2014

2014-09-15

WASHINGTON, DC – September 13, 2014 – In extended follow-up from a clinical trial, a self-expanding transcatheter aortic valve was shown to have low rates of all-cause mortality and major stroke. Findings were reported today at the 26th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium. Sponsored by the Cardiovascular Research Foundation (CRF), TCT is the world's premier educational meeting specializing in interventional cardiovascular medicine. Degenerative aortic stenosis is a progressive disease with a poor prognosis in the absence of surgical ...

Results of ISAR-CLOSURE trial reported at TCT 2014

WASHINGTON, DC – September 13, 2014 – A new clinical trial found that vascular closure devices (VCD) are non-inferior to manual compression in patients undergoing transfemoral coronary angiography. Findings were reported today at the 26th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium. Sponsored by the Cardiovascular Research Foundation (CRF), TCT is the world's premier educational meeting specializing in interventional cardiovascular medicine. Vascular closure devices help achieve more rapid hemostasis after coronary angiography, however ...

International study identifies new genetic variants indicating risk for prostate cancer

2014-09-15

An international study co-led by Keck School of Medicine of the University of Southern California (USC) scientists and researchers in the United Kingdom has revealed 23 new genetic susceptibility locations indicating risk for prostate cancer. The data study, analyzing more than 87,000 individuals of European, African, Japanese and Latino ancestry, is the largest of its kind and is the first that combines multiple studies across different ethnic populations. "The goal of this research is to identify regions of the genome that contribute susceptibility to prostate cancer ...

Contaminated water in 2 states linked to faulty shale gas wells

2014-09-15

DURHAM, N.C. -- Faulty well integrity, not hydraulic fracturing deep underground, is the primary cause of drinking water contamination from shale gas extraction in parts of Pennsylvania and Texas, according to a new study by researchers from five universities. The scientists from Duke, Ohio State, Stanford, Dartmouth and the University of Rochester published their peer-reviewed study Sept. 15 in the Proceedings of the National Academy of Sciences. Using noble gas and hydrocarbon tracers, they analyzed the gas content of more than 130 drinking water wells in the two ...

Gut bacteria tire out T cells

2014-09-15

Leaky intestines may cripple bacteria-fighting immune cells in patients with a rare hereditary disease, according to a study by researchers in Lausanne, Switzerland. The study, published in The Journal of Experimental Medicine on September 15, may explain why these patients suffer from recurrent bacterial infections. Patients with a disease called common variable immunodeficiency (CVID) suffer from recurrent bacterial infections as a result of faulty immune cells. But despite these immune defects, CVID patients rarely contract viral infections. New data from Matthieu ...

T-bet tackles hepatitis

2014-09-15

A single protein may tip the balance between ridding the body of a dangerous virus and enduring life-long chronic infection, according to a report appearing in The Journal of Experimental Medicine. Hepatitis B and C viruses cause chronic infections in roughly three-quarters of infected people, putting these individuals at risk for developing liver diseases including cirrhosis and cancer. A few patients successfully eliminate infection, thanks primarily to virus-fighting immune cells called CD8+ T cells. The protective effects of CD8+ T cells depend on a cellular protein ...

Gas leaks from faulty wells linked to contamination in some groundwater

2014-09-15

COLUMBUS, Ohio—A study has pinpointed the likely source of most natural gas contamination in drinking-water wells associated with hydraulic fracturing, and it's not the source many people may have feared. What's more, the problem may be fixable: improved construction standards for cement well linings and casings at hydraulic fracturing sites. A team led by a researcher at The Ohio State University and composed of researchers at Duke, Stanford, Dartmouth, and the University of Rochester devised a new method of geochemical forensics to trace how methane migrates under ...

Rice rolls 'neat' nanotube fibers

2014-09-15

The very idea of fibers made of carbon nanotubes is neat, but Rice University scientists are making them neat -- literally. The single-walled carbon nanotubes in new fibers created at Rice line up like a fistful of uncooked spaghetti through a process designed by chemist Angel Martí and his colleagues. The tricky bit, according to Martí, whose lab reported its results this month in the journal ACS Nano, is keeping the densely packed nanotubes apart before they're drawn together into a fiber. Left to their own devices, carbon nanotubes form clumps that are perfectly ...

1 in 5 men reports violence toward intimate partners

2014-09-15

ANN ARBOR, Mich. —One in five men in the U.S. reports violence towards their spouse or significant other, says a new nationally-representative study by the University of Michigan. The analysis also found that male aggression toward a partner is associated with warning signs that could come up during routine health care visits, including irritable bowel syndrome (IBS) and insomnia, in addition to better known risks like substance abuse and a history of either experiencing or witnessing violence as a child. The findings appear in the Journal of the American Board of Family ...
