Some stents that keep blood vessels open to treat heart disease are poorly designed to resist shortening, according to publications in the Journal of Interventional Cardiology. A case report published in the journal by Dr. Cindy Grines, of the Detroit Medical Center Cardiovascular Institute, and her colleagues describes a patient who experienced a heart attack after the recently marketed Ion stent (Boston Scientific, Natick, MA) in his artery shortened and accordioned. The articles indicate that some stents are susceptible to becoming deformed, which could result in adverse clinical consequences.
