The impact of invasive treatment of superficial venous insufficiency of the lower extremities on cardiac functions

Abstract

Objective The aim of the study was to investigate the effect of invasive treatment for chronic venous insufficiency (CVI) on cardiac hemodynamics. Methods Fifty three patients diagnosed with saphenofemoral junction or great saphenous vein insufficiency in a level above C3 according to Clinical-Etiology-Anatomy-Pathophysiology classification were included in the study. All the patients underwent 2D echocardiography before and 3 months after the invasive treatment. Results In postinvasive treatment echocardiographic assessment, significant decreases in right ventricular end-diastolic diameter ( p = 0.006), TAPSE ( p = 0.006), tricuspid E wave velocity ( p = 0.004), tricuspid E/A ratio ( p < 0.001), sPAB ( p = 0.017), tricuspid lateral s' wave velocity ( p = 0.004), and right ventricular free wall longitudinal strain rate ( p = 0.011) were observed. Conclusions The invasive treatment of superficial venous insufficiency of the lower extremities may lead to reduction in the increased venous return in the supine position subclinically.
