The aim – to present to the medical community the functioning algorithm of the heart team concept in the diagnosis and surgical treatment of chronic thromboembolic pulmonary hypertension (CTEPH) in Ukraine. The concept of the CTEPH team implies a multi-disciplinary approach to the diagnosis and, consequently, surgical treatment of CTEPH with the participation of a radiologist, a pulmonologist, a cardiologist, a hematologist, a neurologist, and a cardiac surgeon. Considering the low incidence of the disease, the need for high-tech diagnostic tools, including CT angiography and angiopulmonography, as well as challenges of evaluating the operability of patients and the technical complexity of operations, patients with CTEPH are get together in the so-called reference centers. Within the framework of the CTEPH team concept, specific protocols and «road maps» have been developed for both diagnosis and treatment of the disease. In order to eliminate subjectivity in determining the operability of a patient with CTEPH, a special algorithm has been developed, which is applied to a clinical case for illustration. Monitoring patients with pulmonary embolism who are qualifed for a newly coined definition – postembolic pulmonary syndrome, has become a new task of the reference centers. The new syndrome is suggested to include CTEPH, as well as a similar, but not identical pathological condition, named chronic thromboembolic lung disease. The treatment of choice for CTEPH is pulmonary thrombendarterectomy. Mandatory elements of the surgical protocol include the creation of a «dry» operating field by means of a temporary circulatory arrest under deep hypothermia of 18 °C. Operations for distal lesions of the pulmonary arteries have become a recent achievement. The success of the operation depends on the anatomical type of the lesions, the degree of distal arteriopathy, the extent of the intervention, and the comorbid factors. Immediate and long-term results of the operation are evaluated as good and very good. The long-term survival of patients after surgery is significantly higher than of those who were administered medical treatment.Conclusions. Patients with suspected CTEPH should be referred to a reference expert center for diagnosis verification and operability determining. The standard diagnosis of CTEPH is angiopulmonography with simultaneous measurement of pressure in the right heart; the standard treatment is pulmonary thrombendarterectomy.

The paper gives current approaches to treating chronic thromboembolic pulmonary hypertension (CTEPH) from the document «Federal Guidelines for the Diagnosis and Treatment of CTEPH» approved at the Third Russian Congress on Pulmonary Hypertension on December 11, 2015. The guidelines had been elaborated to optimize the treatment of patients with CTEPH on the basis of an analysis of the data of the present-day registries and multicenter randomized clinical trials, national and international guidelines and consensus documents, and documents published in recent years. CTEPH is a unique form of pulmonary hypertension since it is potentially curable by surgical treatment. The paper presents indications for and contraindications to pulmonary thromboendartectomy; preparation for surgery; operating room facilities; the specific features of postoperative management and possible complications; and long-term results. In terms of therapy, in addition to non-pharmacological measures, the authors discuss maintenance and specific treatment options for CTEPH, balloon pulmonary angioplasty, and lung/heart-lung transplantation. In conclusion, they propose a management algorithm in patients with CTEPH and requirements for its problem to the center of experts.

Chronic thromboembolic pulmonary hypertension (CTEPH) is precapillary pulmonary hypertension, in which chronic obstruction of large and middle branches of pulmonary arteries (PAs) and secondary changes in the lung microcirculatory bed result in a progressive increase in pulmonary vascular resistance and PA pressure with the development of severe right cardiac dysfunction and heart failure. CTEPH is a unique form of pulmonary hypertension since it is potentially curable by surgical treatment. The diagnostic criteria for CTEPH are a mean PA pressure of ≥25 mm Hg, as evidenced by right heart catheterization; a PA wedge pressure of ≤15 mm Hg; a pulmonary vascular resistance of >2 Wood units; the presence of chronic/organized thrombi/emboli in the elastic PAs (pulmonary trunk, lobular, segmental, subsegmental PAs); effective anticoagulant therapy at therapeutic dosages over at least 3 months. Up to now, our country has had no guidelines for the diagnosis and treatment of this rare severe disease that, when appropriately untreated, has an extremely poor prognosis. The main task in the preparation of this document was to generalize and analyze the data of current registries, multicenter randomized clinical trials, national and international guidelines, and consensus documents recently published on this problem in order to optimize a diagnostic process and treatment in this category of patients. Part 1 gives a definition of CTEPH, its place in the clinical classification, epidemiology and prognosis, risk factors, pathogenesis and morphology, diagnostic approaches and determination of operability in patients, and specific features of differential diagnosis.
