- Abstract
Background: Unilateral chronic thromboembolism pulmonary disease (CTEPD) is very rare. There is limited information on the safety and efficacy of pulmonary endarterectomy (PEA) in this population. This study investigated the effectiveness of PEA in this unique disease., Methods: This multicentre study included patients with unilateral CTEPD from three referral centres in the United States, Turkey, and Iran. The patients' demographic information, 6-minute walk test distance (6MWD), New York Heart Association (NYHA) functional class, and haemodynamics were evaluated., Result: Of the 1,031 patients who had undergone PEA, 39 patients (3.7%) had pure unilateral involvement, of whom 28 were female (71.8%). There was a significant improvement in the mean pulmonary artery pressure (mPAP, 26 mmHg vs 21 mmHg; p=0.011) and pulmonary vascular resistance (PVR, 202 vs 136 dynes∗sec
1 ∗cm-5 ; p=0.014). There was also a significant improvement in NYHA functional class (p<0.001) and 6MWD (360 vs 409 m; p<0.001). In the nine patients with normal haemodynamic parameters at rest, there was no significant change in median 6MWD (448.5 vs 449 m; p=0.208), mPAP (19 mmHg vs 16.5 mmHg; p=0.397), and PVR (129 vs 84.5 dynes∗sec1 ∗cm-5 ; p=0.128). The most common postoperative complication was ipsilateral pleural effusion. One patient needed extracorporeal membrane oxygenation support. No patient died within the 1-year follow up., Conclusion: Pulmonary endarterectomy is a safe and effective procedure for improving the symptoms and haemodynamic parameters of patients with unilateral CTEPH. Symptomatic patients with unilateral chronic thromboembolic disease are suitable for PEA., Competing Interests: Conflicts of Interest The authors declare no conflict of interest regarding this study., (Copyright © 2024 Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) and the Cardiac Society of Australia and New Zealand (CSANZ).
