Surgical management of patients with severe aortic stenosis and low left ventricular contractility
This review is devoted to the problem of “classical” low-flow, low-gradient aortic stenosis, its diagnosis, treatment and prognosis. This group of patients is one of the hardest among all patients with aortic stenosis. This problem is poorly understood and requires a lot of attention. In recent years, due to various reasons (including the improvement of diagnostic arsenal), there is a clear increase in the frequency of occurrence of such patients. “Classical” low-flow, low-gradient aortic stenosis, according to various data, occurs in about 5-10% of patients with severe aortic stenosis. However, the diagnosis of this pathology is faced with significant difficulties. The main objective of the diagnosis in this case is the differentiation of the true severe from pseudosevere stenosis of the aortic valve. The purpose of this review is to show the latest results of researches aimed at analyzing the methods of diagnosis and the effectiveness of various types of treatment of “classical” low-flow, low-gradient aortic stenosis.
