Access free multiple choice questions on this topic. Introduction. 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 …

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 …

Abstract. 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 …

Introduction. Accurate pulmonary capillary wedge pressure (PCWP) measurements are critical in the evaluation of patients with pulmonary and cardiac pathology. Obtained during right heart catheterization (RHC), PCWPs are required to differentiate between patients with pre-capillary, group 1 pulmonary arterial hypertension (PAH), and post-capillary, …

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.

The pulmonary artery catheter (PAC; Swan-Ganz or right heart catheter) can be used for a variety of clinical purposes. Interpreting hemodynamic data from PACs is important for the diagnosis and management of a range of conditions including shock and pulmonary artery hypertension ( table 1 ). The interpretation of hemodynamic values and pressure tracings …

Invasive assessment of mitral stenosis is typically performed with simultaneous LV and pulmonary capillary wedge pressure (PCWP) waveform analysis to calculate the mean transvalvular gradient. While the mean PCWP typically reflects the mean left atrial pressure, it is important to note the limitations of this approach ( Figs. 23.8 and 23.9 ).
