Hypertrophic Cardiomyopathy Treatment

For children with hypertrophic cardiomyopathy (HCM), treatment is focused on the areas of greatest concern such as decreased heart filling, arrhythmia and obstruction to blood flow caused by the thickened heart muscle.

The treatment goals are to:

  • Control symptoms related to heart obstruction
  • Improve filling of heart chambers
  • Prevent or control arrhythmias and risk of sudden death

Common medications include:

  • Beta-blockers and calcium channel blockers
  • Propranolol and verapamil to decrease outflow obstruction by slowing heart rate and relaxing heart
  • Anti-arrhythmic medications such as amiodarone and disopyramide to reduce the risk of sudden cardiac death.
  • Diuretics and digoxin are not usually used with HCM patients with obstruction because these drugs can worsen the obstruction of blood flow out of the heart.

For more advanced disease, other interventions may be necessary such as:

  • Implantable pacemaker or defibrillator
  • Septal myectomy
  • Mechanical ventilator support (intubation)
  • Cardiac assist devices (ECMO, LVAD, BIVAD)
  • Heart transplantation
