Which echocardiographic view is ideal for assessing right ventricular function?

The subcostal view is particularly effective for assessing right ventricular function due to its positioning and ability to visualize the right heart structures comprehensively. In this view, the transducer is placed below the xiphoid process and angled towards the left shoulder, allowing for a clear representation of the right ventricle, right atrium, and their relationships to other cardiac structures.

This view is instrumental in evaluating right ventricular size, wall motion, and hemodynamics, especially in cases of right-sided heart failure or pulmonary hypertension. The subcostal view often provides optimal visualization of the interventricular septum and can help in assessing right ventricular outflow tract obstruction.

Other views, such as the apical five-chamber view, parasternal short-axis view, and apical two-chamber view, while useful for different cardiac assessments, do not provide the same level of detailed imaging specifically pertinent to right ventricular function. The apical views focus more on the left heart and do not allow for as thorough an evaluation of right ventricular structure and function as the subcostal view does. Therefore, the subcostal view stands out as the ideal choice for assessing right ventricular function in echocardiography.
