Cardiology #16 (Pulmonic & Tricuspid Valve Disorders) Flashcards
What is the pathophysiology of pulmonic stenosis?
Right ventricular outflow obstruction of blood
MC etiology of pulmonic stenosis
Almost always congenital and a disease of the young
Murmur of pulmonic stenosis
harsh, mid-systolic ejection crescendo-decrescendo murmur (heard best at LUSB) that radiates to the neck.
-Murmur increases with inspiration.
-Systolic ejection click
Treatment for pulmonic stenosis
-Balloon valvuloplasty
Pulmonic regurgitation is almost always ______. Explain the pathophysiology.
Congenital
Retrograde blood flow from pulmonary artery into RV –> R-sided volume overload
What is the name of the murmur associated with pulmonic regurgitation
Graham-Steell murmur
Explain the murmur of pulmonic regurgitation
-Brief decrescendo early diastolic murmur at LUSB with full inspiration.
What things increase the murmur of pulmonic regurgitation
Inspiration (MC)
Squatting, supine
What things decrease the murmur of pulmonic regurgitation?
Valsalva, standing, expiration
Treatment for pulmonic regurgitation
No treatment needed in most (most well tolerated)
Pathophysiology of Tricuspid stenosis
-Blood backs up into the right atrium –> RA enlargement –> right-sided heart failure
Explain the murmur of Tricuspid stenosis
Mid-diastolic murmur at the LLSB. Low frequency.
What is Carvallo’s Sign?
Increased murmur intensity with inspiration
Murmur of Tricuspid Regurgitation
Holosystolic, blowing high-pitched murmur at the subxyphoid area (left mid sternal border)
What is one other symptom of Tricuspid Regurgitation that can be present?
Pulsatile liver
