Abstract
The patient was a 66-year-old man who developed exacerbation of respiratory and heart failure that necessitated tracheal intubation. The exacerbation was considered to be largely caused by asthma-chronic obstructive pulmonary disease overlap syndrome and type 3 pulmonary hypertension. However, left diaphragmatic eventration and tracheal stenosis were also found. We hypothesized that diaphragmatic eventration and tracheal stenosis surgeries would improve the patient's pulmonary function, pulmonary hypertension, and cardiac function. Postoperatively, he recovered well and was discharged home on room air, with a good performance status. He also showed improved pulmonary hypertension on echocardiography and improved pulmonary function test results.
