Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) is a disabling condition that is being increasingly recognised. It is unique as a cause of pulmonary hypertension in that it is surgically curable. We wish to highlight the importance of recognition and early referral of any patient who may have CTEPH even in the absence of resting pulmonary hypertension as excellent results can be achieved by restoring pulmonary vascular anatomy, reducing exercise-induced pulmonary hypertension, and reducing dead-space ventilation. We present a case that illustrates these points and discuss our experience as a referral centre for CTEPH.
