Lessons learned in developing a chronic thromboembolic pulmonary hypertension program

Abstract

Purpose of review Chronic thromboembolic pulmonary hypertension (CTEPH) is a deadly underdiagnosed form of pulmonary hypertension, traditionally treated with surgical extraction of thrombo-fibrotic lesions via pulmonary thrombendarterectomy (PTE) surgery. More recently, treatment options have expanded to pulmonary vasodilator medical therapy and balloon pulmonary angioplasty (BPA). This has led to increased awareness and detection of CTEPH, as well as growing interest in performing PTE and BPA. This review will describe the steps required to build a successful CTEPH team in the context of the rapidly evolving treatment of CTEPH. Recent findings CTEPH care requires a multidisciplinary team, including a Pulmonologist or Cardiologist expert in Pulmonary Hypertension, a PTE surgeon, a BPA interventionalist, a dedicated radiologist, cardiothoracic anesthesia and Vascular Medicine or Hematology. Careful assessment of precise imaging and hemodynamic data is needed for operability assessment in the context of the experience of the CTEPH team and surgeon. Medical therapy and BPA are indicated for inoperable CTEPH and residual CTEPH after PTE. Increasingly, multimodality approaches, including surgery, BPA and medical therapy are utilized for best outcomes. Summary An expert CTEPH center requires a multidisciplinary team with dedicated specialists, and time to develop the experience and expertise to achieve high volumes and good outcomes.
