Subclinical Right Ventricular Dysfunction by Strain Analysis
The peculiar shape of the right ventricle (RV), its position within the chest, and the thinness of its free wall have always represented a formidable challenge for the assessment of RV size and function by conventional 2-dimensional echocardiography. Over time, a large number of 2D echocardiography and Doppler parameters have been proposed to describe RV geometry and function. However, most of ...
متن کاملAssociation of subclinical right ventricular dysfunction with obesity.
OBJECTIVES The purpose of this research was to identify the determinants of right ventricular (RV) dysfunction in overweight and obese subjects. BACKGROUND Right ventricular dysfunction in obese subjects is usually ascribed to comorbid diseases, especially obstructive sleep apnea. We used tissue Doppler imaging to identify the determinants of RV dysfunction in overweight and obese subjects. ...
متن کاملSubclinical Right Ventricular Dysfunction in Patients with Severe Aortic Stenosis: A Retrospective Case Series
INTRODUCTION There is scarce information about right ventricle (RV) function in patients with secondary pulmonary hypertension (PH) undergoing transcatheter aortic valve implantation (TAVI). We aim to identify possible RV abnormalities in patients referred for TAVI with severe aortic stenosis (sAS) and secondary PH. METHODS Objective measures of RV function, as well as noninvasive estimates o...
متن کاملSubclinical Left Ventricular Dysfunction in Patients with Obstructive Sleep Apnea
OBJECTIVE We aimed to investigate whether fragmented QRS (fQRS) is associated with subclinical left ventricular (LV) dysfunction in patients with obstructive sleep apnea (OSA). SUBJECTS AND METHODS A total of 141 patients with OSA who had normal LV ejection fraction (LVEF) were included in the study. The fQRS was defined as the presence of an additional R wave, notching of R or S wave or the ...
متن کاملobvious or subclinical right ventricular dysfunction in diabetes mellitus (type ii): an echocardiographic tissue deformation study
background: diabetes mellitus is capable of impairing the myocardial function. several studies have documented the influential impact of diabetes mellitus on the left ventricular function. the right ventricular function plays a significant role in the overall myocardial contractility; hence, this study was undertaken to evaluate the effect of diabetes mellitus type ii on the right ventricular f...
