Cardiac Murmurs and Maneuvers: Valsalva, Handgrip, Squatting, Inspiration + Quiz

Back w another Cardiology video!

👾Why do we perform Cardiac Maneuvers?
The circulatory system changes when we perform certain cardiac maneuvers
The change in this pattern affects the quality of murmurs
As doctors, we will encounter a lot of cases and not all of them will have a typical presentation.
These maneuvers help us narrow our diagnosis down

👾What are the maeuvers discussed in this video?
- Valsalva maneuver
- Hand grip
- Squatting
- Inspiration

In this video, we'll find out how cardiac meneuvers affect the intensity of murmurs

👾 Most of them are caused by turbulence. Except one. Wanna know which one? Watch the video and find out!

👾Questions in this video
Q1. How does inspiration affect the murmur caused by pulmonary stenosis?
A. Increases
B. Decreases

Q2. Which one is likely to produce a louder murmur?
A. Large VSD
B. Small VSD

Q3. How does the valsalva maneuver affect the murmur caused by hypertrophic cardiomyopathy?
A. Increases
B. Decreases

Q4. How does squatting affect the murmur caused by aortic regurgitation?
A. Increases
B. Decreases

Q5. You are examining a patient w Marfan syndrome. On auscultation, you hear a late systolic crescendo murmur. What is the most likely diagnosis?
A. Mitral valve prolapse
B. Mitral stenosis
C. Aortic regurgitation

Q6. [continuation of Q5] You squeeze the patient’s hand and then auscultate his chest again.
How do you think the murmur has changed?
A. Early onset of murmur
B. Late onset of the murmur
C. Remains the same

These are extremely important for exams like the USMLE

Take special note of all the things I said w a "🌟“ in this video. They are extremely high yield concepts!
