The U.S. Food and Drug Administration (FDA) Medtronic Inc.’s Valiant Captivia Thoracic Stent Graft System to treat type B aortic dissections. Supported by the results of the U.S. Medtronic DISSECTION trial, the new indication provides physicians a minimally invasive alternative to open surgical repair and medical therapy.
radiation dose management, monitoring

Radiation dose continues to rise as the number of computed tomography (CT), nuclear, angiography and fluoroscopy examinations grow, leading to a greater risk of patient overexposure to radiation. Healthcare providers must reinforce their efforts to monitor and visualize dose levels from radiology examinations to enhance patient safety and meet new regulatory demands. There also is a need to justify and optimize the usage of radiation dose to find a balance between safer practice, image quality and lower dose — all for the benefit of the patient. Implementing tools for automatic and continuous follow up of radiation dose is at the forefront of meeting these challenges.

Instead of making a chest incision for open heart surgery, cardiovascular surgeons can now use a new vacuum-like tool to remove potentially deadly, large clots that lodge in patients’ hearts. 

A large-scale analysis assessing the real-world risk of venous thromboembolism (VTE) in chemotherapy patients shows a greater occurrence of VTE than identified in clinical trials. Risk progressively increases during the year following treatment initiation, according to the report.

Physicians have used radiation in medicine for more than a century. The use of radiation in diagnostic imaging, including computed tomography (CT), fluoroscopy, angiography, mammography, computed radiography (CR) and digital radiography (DR), as well as in nuclear medicine, has aided greatly in the diagnosis and treatment of cancer and other diseases. 

Ekos Corp., a BTG International group company, published results of its Ultrasound Accelerated Thrombolysis of Pulmonary Embolism (PE) trial (ULTIMA) in the peer-reviewed journal of the American Heart Association, Circulation. The announcement was made at the International Symposium on Endovascular Therapy (ISET), Miami, Fla.

Miracor Medical Systems completed four months’ follow-up of patients enrolled in the “Prepare RAMSES” clinical trial of PICSO (Pressure-controlled Intermittent Coronary Sinus Occlusion) System.

Heart transplant patients may live 20 years or more after surgery, according to a study in The Annals of Thoracic Surgery. Hector Rodriguez Cetina Biefer, M.D. and Markus J. Wilhelm, M.D., from the University Hospital Zurich in Switzerland, led a research team that examined long-term outcomes in 133 patients from their institution who underwent heart transplantation from 1985 to 1991.

W. L. Gore & Associates Inc. (Gore) and AAAneurysm Outreach have partnered to raise awareness and drive screening of individuals at-risk of abdominal aortic aneurysm (AAA).
