  FDA early alert flags balloon burst risk in Edwards SAPIEN M3 mitral delivery systems after one death and one serious injury
  The Food and Drug Administration (FDA) issued an early alert covering four lots of Commander M delivery systems used with the SAPIEN M3 transcatheter mitral valve replacement system, saying a potential balloon burst during inflation can lead to embolism or the need for surgery. As of Oct. 5, Edwards Lifesciences had reported one death and one serious injury tied to the issue, according to the FDA. The FDA said the affected lots should not be used, and an Oct. 5 Edwards letter told customers to search their inventory for and remove the affected product.
