Pulmonary thromboendarterectomy (PTE) provides a curative alternative to th
e otherwise fatal condition of chronic thromboembolic pulmonary hypertensio
n (CTEPH). However, the condition is under-diagnosed due to a lack of aware
ness. An acceptable operative mortality of around 10% and long-term surviva
l exceeding medical therapy or transplantation makes PTE a favourable choic
e for the treatment of CTEPH. Outcome is further optimised if the disease i
s diagnosed early and patients referred to specialised centres. An increase
in the number of surgical procedures will also contribute to lower the mor
tality associated with this condition.
