Pulmonary capillary wedge pressure (PCWP) is frequently used to assess left ventricular filling, represent left atrial pressure, and assess mitral valve function. It is measured by inserting a balloon-tipped, multi-lumen catheter (Swan-Ganz catheter) into a central vein and advancing the catheter into a branch of the pulmonary artery.

Pulmonary capillary wedge pressure. Pulmonary capillary wedge pressure or PCWP, provides an indirect estimate of left atrial pressure 1) or left ventricular end-diastolic pressure 2), which is the “gold standard” for determining left ventricular filling pressure 3). However, recent studies have shown that, in pulmonary arterial hypertension (PAH) patients, PCWP can lead to erroneous …

Under these circumstances the PCWP is a reflection of left-atrial pressure with a and v waves and x and y descents. The PCWP tracing exhibits several important differences from a directly measured atrial-pressure waveform. The c wave is absent because of the damped nature of the pressure wave. The v wave typically exceeds the a wave on the PCWP tracing. Because the …

Background: A large V wave in a pulmonary capillary wedge pressure (PCWP) tracing is characteristic of mitral regurgitation. However, the V wave is often increased in patients without or with no significant mitral regurgitation. Methods and results: The V wave was in the PCWP tracing investigated in 65 patients using transmitral flow (TMF) and pulmonary venous flow …

The V wave on PCWP tracing corresponds to (1) T wave on ECG and (2) descent of pressure tracing on LV recording V wave > 2x mean PCWP is suggestive of severe MR V wave > 3x mean PCWP is diagnostic of severe MR Absence of significant V …

https://pubmed.ncbi.nlm.nih.gov/6641038/
We have previously demonstrated that a large V wave in the pulmonary capillary wedge tracing may occur in the absence of mitral regurgitation. This study evaluates the role of left atrial and pulmonary vein compliance on such a finding. We studied 11 patients with coronary disease, without clinical or angiographic mitral regurgitation.
