A cardiac micro-pump useful in cases of decompensated cardiomyopathy in DMD

American researchers report the successful implantation of a temporary Impella 5.5 endocavitary micropump developedby Abiomed:

  • the patient was a 14yearold boy with Duchenne muscular dystrophy,
  • he had been transferred for treatment of cardiogenic shock in the context of decompensation of his cardiomyopathy.
  • the implantable device was inserted through the right axillary artery into the left ventricle.
  • It enabled rapid and substantial recovery of cardiac function in this adolescent.

The authors detail the technical adaptations necessary to optimise the method and emphasise that this is a temporary solution preceding the implementation of heavier and more durable ventricular assist devices.
