Right Ventricular Diastolic Dysfunction in Arterial Systemic Hypertension: Analysis by Pulsed Tissue Doppler

Abstract

Arterial systemic hypertension is associated to right ventricular longitudinal diastolic dysfunction. This dysfunction involves the prolongation of active relaxation, which is independently associated with the degree of right ventricular hypertrophy and the impairment of passive wall properties, which is mainly due to ventricular interaction occurring under left ventricular pressure overload conditions.
