 | The walls of the aorta, the largest blood vessel carrying blood from the heart, exhibits a response to electric fields known to exist in inorganic and synthetic materials. The discovery could have implications for treating human heart disease. ...> Full Article |
To see if a more naturally asymmetric design could improve blood flow, researchers created aluminum models of asymmetric valves, similar in size to the valves of an adult human heart.

David H. Adams, MD, Marie-Josée and Henry R. Kravis Professor and Chairman of the Department of Cardiothoracic Surgery, Samin K. Sharma, MD, the Zena and Michael A. Weiner Professor and Director of the Cardiac Catheterization Laboratory, and Annapoorna S. Kini, MD, Associate Professor and Associate Director of the Cardiac Catheterization Laboratory at the Mount Sinai Medical Center, have performed the first implantation of the Medtronic CoreValve® Transcatheter Aortic Valve Prosthesis in the United States.

 | The Bluhm Cardiovascular Institute of Northwestern Memorial Hospital recently implanted a patient with two of the smallest experimental ventricular assist devices currently available for study in humans. ...> Full Article |
In a Canadian first, the Peter Munk Cardiac Centre used a new kind of left ventricular assist device (LVAD) to treat a patient with advanced heart failure. The new device is longer lasting than older generation LVADs and may eliminate the need for a second LVAD -- a major drawback with the old technology.

 | For women with mild heart failure, device therapy is an extremely attractive option to prevent progression of the disease. A new study found that women with mild heart disease who had a cardiac resynchronization device combined with a defibrillator (CRT-D) implanted had a 70 percent reduction in heart failure alone and a 72 percent reduction in death from any cause. This is the first study in which a heart failure therapy has proven more effective in women than in men. ...> Full Article |
After receiving only the fourth US implant of a new-generation, Utah-made ventricular assist device, an Idaho man with heart failure is looking forward to resuming an active life following an operation on March 17 at University of Utah Hospital.

 | Arrhythmic hearts soon may beat in time again, with minimal surgical invasion, thanks to flexible electronics technology developed by a team of University of Illinois researchers, in collaboration with the University of Pennsylvania School of Medicine and Northwestern University. These biocompatible silicon devices could mark the beginning of a new wave of surgical electronics. ...> Full Article |
 | A team of cardiologists, materials scientists, and bioengineers have created and tested a new type of implantable device for measuring the heart's electrical output that they say is a vast improvement over current devices. The new device represents the first use of flexible silicon technology for a medical application. The technology may herald the next generation of active, flexible, implantable devices for applications in cardiology and neurology. ...> Full Article |
 | A landmark study has successfully demonstrated a 29 percent reduction in heart failure or death in patients with heart disease who received an implanted cardiac resynchronization therapy device with defibrillator (CRT-D) vs. patients who received only an implanted cardiac defibrillator (ICD-only). ...> Full Article |
Three patients at NewYork-Presbyterian Hospital/Columbia University Medical Center were among the first in the United States to be implanted with a next-generation artificial heart pump called the DuraHeart Left-Ventricular Assist System. The surgeries took place earlier this year. NewYork-Presbyterian/Columbia is one of only three centers in the US currently enrolling patients in a clinical trial studying the device.

Patients with severe heart failure can be bridged to eventual transplant by a new, smaller and lighter implantable heart pump, according to a just-completed study of the device. Results of this third-generation heart assist device were reported at the 58th annual meeting of the American College of Cardiology on March 30.
