Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare and late complication of acute pulmonary embolism (PE) that has not resolved despite adequate anticoagulation. In most patients with PE, resolution of the embolus and restoration of blood flow occur. However, for unknown reasons, in a small subset of patients, undissolved blood clots in the pulmonary arteries result in the formation of scar tissue and incomplete recovery of perfusion. If left untreated, progressive right-sided heart failure and pulmonary hypertension may ensue. Although challenging, early identification and accurate diagnoses are important for implementing the appropriate treatment strategy.
