Summary

Pulmonary thromboendarterectomy offers a potentially correctable treatment for chronic thromboembolic pulmonary hypertension, significantly improving patient outcomes. While risks like reperfusion lung injury exist, the procedure has evolved into a viable option for managing this condition.

Area of Science:

  • Cardiovascular Medicine
  • Pulmonary Hypertension Research

Background:

  • Chronic thromboembolic pulmonary hypertension (CTEPH) was once considered rare, but is now recognized as a treatable cause of pulmonary hypertension.
  • Significant advancements in surgical techniques have transformed CTEPH management over the last four decades.

Purpose of the Study:

  • To review the evolution and current status of pulmonary thromboendarterectomy (PTE) for CTEPH.
  • To highlight the outcomes and persistent challenges associated with PTE.

Main Methods:

  • Analysis of global data on approximately 2500 performed thromboendarterectomy procedures.
  • Review of mortality rates from experienced centers managing CTEPH.

Main Results:

  • Mortality rates for PTE at experienced centers have decreased to 4-8%.

  • Successful PTE leads to substantial improvements in right ventricular function, gas exchange, exercise capacity, and quality of life.
  • Reperfusion lung injury and residual pulmonary hypertension are key factors contributing to postoperative mortality.

    • Conclusions:

    • Pulmonary thromboendarterectomy is a potentially curative treatment for CTEPH.
    • Despite advancements, managing complications like reperfusion lung injury and residual hypertension remains critical for improving patient survival and outcomes.
