ФГБУ «Национальный медицинский исследовательский центр сердечно-сосудистой хирургии имени А.Н. Бакулева» Минздрава России, Москва, Российская Федерация Несоответствие между протезом и пациентом (PPM) возникает, когда протез клапана, имплантированный во время операции, слишком мал по отношению к размеру тела пациента, что вызывает высокие трансвальвулярные градиенты. Мы исследовали непосредственные результаты и зависимость трансвальвулярных градиентов от индекса массы тела и площади поверхности пациента после протезирования аортального клапана протезом «БиоЛАБ» с маленькими размерами. Материал и методы.

Background. The use of radiation therapy for the treatment of tumors of the chest сan lead to the development of cardiac pathology, including that of the valves and coronary arteries. Study aim: to analyze the specifics of post-radiation lesions of the valvular apparatus and coronary arteries, and to assess the immediate results and risks of surgical correction of detected defects. Materials and  methods. In the Emergency department of surgery of acquired heart disease of A. N. Bakulev National Medical Research Center of Cardiovascular Surgery in the period from 2004 to 2017 were examined and operated 46 patients aged 35–81 years (mean age 56±12.4 years, 80 % women). The period from primary irradiation of the chest to surgical treatment of valvular pathology ranged from 4 to 40 years. Indications for thoracic radiotherapy were Hodgkin’s lymphoma in 23 patients (50 %), breast cancer – in 20 (43 %). Results. Stenosis of the aortic valve was the leading defect in 42 patients (91 %). According to coronary angiography, coronary artery disease was diagnosed in 31 patients (67 %). Isolated aortic valve prosthesis was performed in 14 (30 %) patients, other operations were combined. Hospital mortality was 11 % (5 patients). There were no deaths among patients who underwent radiation therapy after mastectomy. Main nonlethal complications were: pericardial effusion in 6 patients (13 %), hydrothorax requiring repeated pleural punctures in 5 patients (11 %). Conclusion. The variety of clinical manifestations of radiation heart disease and its progressive nature emphasize the need for long-term dynamic observation of patients after thoracic irradiation in order to timely identify the pathology and eliminate the risk of sudden cardiac complications and the development of severe heart failure decompensation.
