ABSTRACT Chronic thromboembolic pulmonary hypertension is the only potentially curable form of pulmonary hypertension, assuming that surgical treatment is possible. However, there are hindrances to making a definitive, noninvasive diagnosis. We present the case of a 40-year-old female patient with idiopathic pulmonary arterial hypertension, confirmed in 1994. This patient developed thrombi in pulmonary vessels (as an overlap syndrome) mimicking chronic thromboembolic pulmonary hypertension. The identification of these conditions, which present high intraoperative mortality and unsatisfactory surgical resolution, is quite difficult in clinical practice. We discuss the current approach to candidate selection for surgical treatment of chronic thromboembolic pulmonary hypertension and the possible repercussions of inappropriate selection.
