Why the study?
Pulmonary tumor embolism is a rare cause of acute decompensated pulmonary hypertension with poor prognosis that should be considered in patients with advanced lung malignancy presenting with right heart failure.
Pulmonary tumor embolism should be considered as a rare cause of acute decompensated pulmonary hypertension in patients with advanced lung malignancy presenting with right heart failure.
A rare cause of acute decompensated pulmonary hypertension is pulmonary tumor embolism (PTE), which is an uncommon complication of advanced lung malignancy. Patients diagnosed with PTE typically have a poor prognosis, and so patients with advanced lung tumors who present with signs of right heart failure and respiratory support should be evaluated for PTE. We present a case of a 54-year-old Hispanic female who initially presented with a one-month history of dysphagia, who was found to have acute pulmonary hypertension secondary to invasion of the pulmonary arteries by lung adenocarcinoma.
