Other typical signs of<unk>  include an accentuated<unk>  component of the second heart sound, a right ventricular third heart sound, and parasternal heave indicating a hypertrophied right ventricle. Signs of systemic congestion resulting from right-sided heart failure include jugular venous distension, ascites, and hepatojugular reflux. Evidence of tricuspid insufficiency and pulmonic regurgitation is also sought and, if present, is consistent with the presence of<unk> .
