Zusammenfassung
Ein bedeutender Anteil an Patienten mit einer schwergradigen Stenosierung der Aortenklappen in der Ruheechokardiographie haben eine „Low-flow-low-gradient“-Aortenklappenstenose. Das diagnostische und therapeutische Management dieser Patienten sind komplex, da häufig eine linksventrikuläre Funktionseinschränkung vorliegt, die ein höheres Risiko bei operativem Klappenersatz bedingt und den Stenosegrad in der Echokardiographie verfälschen kann. Es sind teils mehrere diagnostische Schritte notwendig, um diese Patienten eindeutig zu diagnostizieren und der optimalen Therapie zuzuführen.
Abstract
Many patients with severe aortic stenosis have a “low-flow, low-gradient” aortic stenosis. The management of these patients can be quite difficult, as these patients often show impairment of the left ventricle, which can lead to false measurements of the severity of stenosis and also leads to a higher risk during aortic valve replacement. More diagnostic tools than only standard echocardiography are needed to correctly differentiate true severe aortic stenosis from pseudo severe aortic stenosis.
