Questions and Answers

What is the primary function of an Intra-Aortic Balloon Pump (IABP)?

  • Assist in inflating the lungs during surgery
  • Control the levels of oxygen in the bloodstream
  • Aid in expanding blood vessels in the legs
  • Provide mechanical support to the heart during diastole (correct)

When is the Berlin Heart EXCOR VAD typically used?

  • To treat congenital lung malformations
  • In small children with heart failure (correct)
  • In adults with structural heart abnormalities
  • For patients who need assistance with lung function

What distinguishes the Berlin Heart EXCOR VAD from the HeartWare ventricular assist device?

  • Intended patient population, with HeartWare for small children
  • Size, with the Berlin Heart being larger (correct)
  • Function, with HeartWare being used for acute heart failure
  • Pump mechanism, with HeartWare using counter pulsation
