Background: Of the types of pulmonary hypertension, chronic thromboembolic pulmonary hypertension (CTEPH) may be cured through pulmonary endarterectomy (PEA). In this study, we investigated patient experiences with PEA for CTEPH treatment in Taiwan.
Methods: We retrospectively reviewed the records of patients who underwent PEA in two medical centers between January 2005 and December 2019. We measured the following outcomes: in-hospital complications, improvements in cardiac function and exercise capacity, survival using Kaplan-Meier analysis after PEA.
Results: Twenty-seven patients (female: 17) with a mean age of 52.6 years underwent PEA. Pre-operatively, most patients were New York Heart Association functional class (NYHA FC) III (n = 19) and IV (n = 7). The mean periods from the onset of symptoms to diagnosis and from diagnosis to operation were 22.6 and 22.3 months, respectively. After PEA, mean intubation time, and length of intensive care unit and hospital stay were 9, 11, and 20 days, respectively. Most patients' NYHA FCs improved to I (n = 15) and II (n = 10). The mean 6-min walk test (6MWT) result improved by 60.5%. The in-hospital mortality, mean follow-up period, and 5- and 10-year overall survival rates were 3.7%, 77.0 months, 96.3%, and 84.3%, respectively. Furthermore, 5- and 10-year disease-specific survival rates were both 96.3%.
Conclusion: When pre-operative and post-operative statuses were compared, we found a significant improvement in NYHA FC and 6MWT distance. Our study also found a lower in-hospital mortality rate compared to other published studies, except compared to the newer data provided by the University of California, San Diego group.
