PTE Surgery

The treatment of choice for CTEPH.

PTE* surgery is the only treatment for CTEPH that can be curative, so it is the recommended first option for CTEPH patients.20

Patients who have operable CTEPH should be referred for surgery without delay.3

  • PTE surgery is a complex bilateral procedure, which requires median sternotomy, cardiopulmonary bypass, deep hypothermia, and periods of circulatory arrest.9
  • PTE allows for the removal of central obstructing lesions, resulting in an improvement and often normalization of pulmonary hemodynamics.1
    • About two-thirds of patients have normal hemodynamics following PTE.26
  • About one-third of patients may have residual PH.25
  • Discover common myths and realities concerning mortality rates of PTE* surgery in these videos from Richard Channick, MD and William Auger, MD.
