Research published in the September 2008 Journal of Vascular Surgery, published by the Society for Vascular Surgery has revealed that the Vascular Medtronic Talent Thoracic Stent Graft™ System (VALOR) is a safe and effective endovascular therapy, as an alternative to open surgery in patients with thoracic aortic aneurysms who were considered candidates for open surgical repair..
Ronald M. Fairman, MD, professor of surgery, chief of the division of vascular surgery at the Hospital of the University of Pennsylvania in Philadelphia and National Principal Investigator, reported the results of this prospective, non-randomized, multi-center, pivotal trial conducted at 38 sites. A total of 195 patients were enrolled in the VALOR Trial and 189 patients were identified as retrospective open surgical subjects. Endovascular enrollment occurred between December 2003 and June 2005 and endovascular results were compared with retrospective open surgical data from three centers of excellence.
Drug-eluting Stents Without Polymers may Help Treat Blocked Coronary Arteries
A new type of drug-eluting vascular stent, which uses materials found naturally in the human body rather than polymers (plastic), has been found to perform as well as commercially

The 30 day VALOR results included perioperative mortality (2.1 percent), major adverse advents (41 percent), incidence of paraplegia (1.5 percent), paraparesis (7.2 percent), and stroke (3.6 percent). The 12 month VALOR results included all-cause mortality (16.1 percent), aneurysm-related mortality (3.1 percent), conversion to open surgery (0.5 percent), target aneurysm rupture (0.5 percent), stent graft migration > 10 mm (3.9 percent), endoleak (12.2 percent), stent graft patency (100 percent), stable or decreasing aneurysm diameter (91.5 percent) and loss of stent graft integrity (four patients). There were no instances of deployment-related events or perforation of the aorta by a graft component.
According to Dr. Fairman, “The Talent Thoracic Stent Graft showed statistically superior performance with respect to acute procedural outcomes (p<0.001), 30 day major adverse events (41 percent vs. 84.4 percent, p<0.001), peri-operative mortality (2 percent vs. 8 percent, p<0.01), and 12 month aneurysm-related mortality (3.1 percent vs. 11.6 percent, p<0.002) when compared to open surgery.”
Angioplasty
Arteries supplying the heart is sometimes blocked by plaque leading to heart attack.Angioplasty is a method by which a part of the blocked artery is expanded to place a stent.Once this is done normal blood flow resumes and the heart regains its normal function.

Obese People More Prone to Severe Persistent Asthma
A new study has found that obese people are significantly more likely to have persistent or severe persistent asthma than their slimmer counterparts.
