В период набора пациентов было последовательно исследовано 232 пациента, в окончательный анализ было включено 186 (80%) пациентов с доступной ППП.</p></sec><sec><title>Критерии включения</title><p>Критерии включения: пациенты с АС (сочетание кальцинированного аортального клапана и максимальной трансаортальной скорости более 2,5 м/с) и доступной ППП для оценки тяжести АС.</p></sec><sec><title>Результаты</title><p>Результаты. Средние показатели Gmax и Gmean, оцененные в ППП, были достоверно выше, а средние значения площади аортального клапана (AVA) и безразмерного индекса (DVI) были ниже по сравнению с аналогичными показателями, оцененными в А5КП (р &lt;0,05). При анализе методом Бленда–Альтмана средняя разница Gmax и Gmean, оцененная в А5КП и ППП, составила 10,2 ± 14,3 и 4,5 ± 8,9 мм рт.ст. соответственно. Средняя разница AVA и DVI, оцененная в А5КП и ППП, составила 0,1 ± 0,15 см2 и 0,02 ± 0,03 соответственно. При использовании ППП у 44 (23%) пациентов удалось реклассифицировать тяжесть АС на более тяжелую степень. Анализ множественной логистической регрессии выявил, что аортосептальный угол является единственным независимым параметром, оказывающим значимое влияние на согласованность в оценке тяжести АС между двумя акустическими проекциями (OШ 0,76; 95% ДИ 0,69–0,83; p &lt; 0,001).</p></sec><sec><title>Выводы</title><p>Выводы. 1. Использование А5КП в значительном проценте случаев может привести к недооценке тяжести АС. Оценка тяжести АС в ППП в дополнение к А5КП может значительно увеличить диагностическую точность эхокардиографического исследования.</p></sec><sec><title>2</title><p>2.

To evaluate the effectiveness of using the right parasternal view (RPV) in addition to the apical five-chamber view (A5CV) for assessing the severity of aortic stenosis (AS) and to identify factors influencing the concordance of AS severity assessment between RPV and A5CV.</p></sec><sec><title>Materials and Methods</title><p>Materials and Methods. During the patient recruitment period, 232 patients were consecutively examined, and 186 (80%) patients with an available RPV were included in the final analysis.</p></sec><sec><title>Inclusion criteria</title><p>Inclusion criteria: Patients with AS (combination of a calcified aortic valve and a peak transaortic velocity &gt;2.5 m/s) and an available RPV for AS severity assessment.</p></sec><sec><title>Results</title><p>Results. The average Gmax and Gmean values assessed in RPV were significantly higher, and the average AVA and DVI values were lower compared to similar values assessed in the A5СV, p &lt;0.05. Bland-Altman analysis showed that the mean differences in Gmax and Gmean between A5CV and RPV were 10.2±14.3 mmHg and 4.5±8.9 mmHg, respectively. The mean differences in AVA and DVI between A5CV and RPV were 0.1±0.15 cm2 and 0.02±0.03 ml, respectively. Using RPV allowed reclassification of AS severity to a more severe degree of aortic stenosis in 44 (23%) patients. Multivariate logistic regression analysis identified the aorto-septal angle as the only independent parameter significantly affecting the concordance of AS severity assessment between the two acoustic projections (OR 0.76; 95% CI 0.69-0.83, p &lt;0.001).</p></sec><sec><title>Conclusion</title><p>Conclusion. 1. The use of A5CV alone may lead to an underestimation of AS severity in a significant proportion of cases. Assessing the severity of aortic stenosis in the RPV in addition to the A5СV can significantly increase the diagnostic accuracy of echocardiography.</p></sec><sec><title>2</title><p>2.The aorto-septal angle is an independent factor significantly influencing the concordance of AS severity assessment between the two echocardiographic views.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>: аортальный стеноз</kwd><kwd>правая парастернальная проекция</kwd><kwd>апикальная пятикамерная проекция</kwd><kwd>реклассификация</kwd><kwd>эхокардиография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aortic stenosis</kwd><kwd>right parasternal view</kwd><kwd>apical five-chamber view</kwd><kwd>reclassification</kwd><kwd>echocardiography</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Osnabrugge R.L., Mylotte D., Head S.J. et al.
