Heart rate variability in aortic valve defects
This review covers the problem of changes in the cardiovascular autonomic control in patients with aortic valve defects. Due to the wide spread of this type of valve damage and a high degree of cardiovascular risk of complications and mortality, this topic is a main problem of modern cardiac surgery. This review presents study results of some authors on changes in heart rate variability as one of the methods for assessing cardiovascular autonomic dysfunction in patients with isolated and combined aortic defects of various etiologies and severity. The significance of heart rate variability in clinical practice for assessing the severity of aortic valve defects and determining the clinical outcome is described. In addition, the review presents data on changes in heart rate variability indices after surgical or transcatheter correction of valve defect.
