It has been found out that right ventricular function is an important predictor of morbidity and mortality in patients with heart failure and pulmonary hypertension (Karas &. Kizer 2012, p 144). Before, prognostic assessment for heart failure was focused on the left ventricle considering this chamber as the primary locus of disease. Now, investigators have focused research on the Right ventricle size and function. RV dysfunction has been shown to be a major predictor of outcome following myocardial infarction, as well as a key prognostic indicator in patients with chronic heart failure. Accurate assessment of RV size and function is an essential component to comprehensive evaluation of the patient with heart failure and/or pulmonary vascular disease (Karas &. Kizer 2012, p. 144). And echocardiography remains the primary tool in RV evaluation for it is noninvasive, portable, inexpensive, and widely available. ...
acoustic windows, as well as RV focused views, in the apical 4-chamber, 5-chamber and coronary-sinus views to better visualize the right ventricle anterior, lateral, and inferior walls (Karas &. Kizer 2012, p. 145). By the viewing the different portions of the right heart thru echocardiography disease patterns such as heart failure and pulmonary hypertension can be evaluated and tracked for prognosis. Echocardiography as a diagnostic assessment of the right heart The right atrium serves three main functions in right ventricle filling: a reservoir for systemic venous return when the tricuspid valve is closed, a passive conduit in early diastole and an active conduit during atrial contraction in late diastole. Right Atrium dimensions have been reported to predict adverse outcome in the setting of primary pulmonary hypertension. Accurate estimation of Right Atrial pressure is important in obtaining reliable noninvasive measurement of pulmonary pressures (Karas &. Kizer 2012, p. 146). On the other hand, the Right Ventricle dilates in response to chronic volume overload, pressure overload, and Right Ventricle systolic failure, and Right Ventricular size has been shown to be a predictor of survival in patients with chronic pulmonary disease and acute pulmonary embolism. Thus the evaluation of normal pressures and measures of the right ventricle is necessary. It also includes assessment of the Right Ventricle outflow tract, the proximal diameter of which is obtained in the parasternal long-axis view. Increased proximal right ventricle outflow tract diameter has been documented to be a manifestation of arrhythmogenic right ventricular cardio myopathy (Karas &. Kizer 2012, p. 146).
