"Chronic elevations in right ventricular afterload, however, allow a series of compensatory geometrical changes to occur; chamber dilation and increased wall thickness allow initial preservation of RV stroke volume, albeit at markedly elevated pressures 4."
"The relevant structures of interest are the right ventricular outflow tract (RVOT) and tricuspid valve; the apical 4 chamber view or parasternal RV inflow views are preferred for the latter, while the former is best assessed with a basal parasternal short axis view."
