Abstrakt:	Objective: to assess the safety and efficiency of radiofrequency pulmonary artery ablation for treatment of residual pulmonary hypertension after pulmonary endarterectomy. Material and Methods: Radiofrequency pulmonary artery denervation (PADN) was performed in 16 patients (10 men, mean age 39 years [26; 51]). Indication for PADN was mean pulmonary artery pressure (PAP) >25 mm Hg with absence of proximal pulmonary artery lesion according to computer tomography. PADN procedure was performed with nonfluoroscopic 3D navigation system. Results: After PADN mean PAP decreased from 37.3 mm Hg [29; 38] to 24.6 mm Hg [17; 30] (p=0.01); pulmonary vascular resistance decreased from 672 dyn∙s∙c-5 [387; 566] to 386 dyn∙s∙c-5 [155; 449] (р=0.02); cardiac output increased from 3.4 l/min [3.2; 3.4] to 3.5 l/ min [3.2; 4.0] (p=0.4); 6-minute walk test distance increased from 427 meters [352; 510] to 447 meters [370; 525] (p=0.16), respectively. Conclusion: Initial results allow to assume that radiofrequency pulmonary artery denervation combined with optimal medical therapy may take its rightful place in the treatment of this category of patients.
