WebSep 27, 2024 · The v‑wave corresponds to the continued venous return to the RA during ventricular systole; that is, right atrial filling with a closed tricuspid valve. The y‑descent corresponds to the decrease in CVP after the tricuspid valve opens, when blood flows from the RA into the right ventricle (RV). Figure 38.1 The CVP waveform. WebGiant v waves may also be present in patients with ventricular septal rupture. In ventricular septal rupture, increased pulmonary venous return owing to the large left-to-right shunt to a left atrium with normal size and compliance is associated with an accentuated v wave.
