Pulmonary capillary wedge pressure (PCWP)

Hello friends, this video introduces a very valuable hemodynamic concept of wedge pressure which essentially reflects LA pressure. It teaches how to identify PCWP tracing correctly, and how to differentiate a wedge tracing from a pulmonary arterial waveform. Hope this helps you in the cath lab!

👉 Correction: As rightly pointed out by one of our viewers, it should have been "after the mitral valve opens" not the tricuspid valve at 04:45!

❓ Active recall questions:
1. How is PCWP measured and what waveforms are obtained?
2. In PCWP tracing, which is bigger v wave or a wave?
3. What is clinical importance of mean PCWP?
4. Does mean PCWP = mean LA pressure?
5. What is normal mean PCWP ?
6. What is the relationship between mean PCWP and pulmonary diastolic pressure?
7. How do the lung zones affect measurement of PCWP?
8. How does presence of PAH interfere with PCWP measurement?
9. What is catheter overwedging?
10. How does presence of sepsis, hypoxemia or acute lung injury affect PCWP?
11. What are differentiating features of PCWP waveform from PA pressure waveform?
12. What are abnormalities of V waves?
13. How does impaired LV compliance affect PCWP waveforms?

About me:
I am Dr. Sonali, an interventional cardiologist from India. I have a special interest in cardiology academics & teaching with an emphasis on building clear concepts with clinical correlation. My channel "Cardiology and Beyond" serves to achieve the same...I hope you find it useful in your clinical practice.
