    Abstract:
    BACKGROUND: The aim of this study was to analyze the results of pulmonary endarterectomy (PEA) performed simultaneously with additional cardiac procedures in a single tertiary-level center. METHODS: Data of patients who underwent PEA with additional cardiac procedures for chronic thromboembolic pulmonary hypertension (CTEPH) in our clinic were retrospectively reviewed using patient records. RESULTS: Between March 2011 and April 2019, 56 patients underwent PEA with additional cardiac surgery. The most common additional procedure was coronary artery bypass grafting (21 patients; 38%). The median intensive care unit and hospital stays were 4 (3-6) days and 10 (8-14) days. Mortality was recorded in six patients (11%). In multivariate analysis, only preoperative pulmonary vascular resistance (PVR) (p = 0.02; odds ratio [OR]: 1.003) and cardiopulmonary bypass duration (p = 0.02; OR: 1.028) were associated with mortality. When the cutoff value of 1000 dyn.s.cm-5 was taken in the receiver operating characteristic curve analysis, preoperative PVR predicted mortality with 83% sensitivity and 94% specificity (area under curve = 0.89; p < 0.01). CONCLUSION: PEA for CTEPH may be performed safely with other cardiac operations. This type of surgery is a complex procedure that should be performed only in expert centers. Patients with high preoperative PVR are at increased risk of perioperative complications.
