Bicuspid-aortic-valve repair shows long-term efficacy

JAMA Cardiology
Reuters Health - 23/09/2020 - A large proportion of bicuspid aortic valve (BAV) repairs using a modified anatomy-based technique remain stable and lead to excellent long-term survival, according to researchers in Germany. BAV, the most common congenital cardiac anomaly, is characterized by a variable degree of fusion between two cusps and the presence of a nonfused cusp that is almost always larger than the two components of the fused cusp. A number of BAV patients will need treatment for either aortic regurgitation or ascending aortic aneurysm, Dr. Ulrich Schneider of Saarland University Medical Center, Homburg, and colleagues note in JAMA Cardiology. Reconstruction of the regurgitant BAV has been successfully performed for more than two decades, they add, but a considerable proportion of the repaired valves failed within five years. To determine how the technique has since evolved, the researchers examined data on a case series of more than 1,000 patients (...
