Pulmonic Valve Flashcards

Q

Pulmonic Valve views and anatomy

A
  • Most anterior valve —> hard to see with TEE — anterior, rightward, and perpendicular to the AV
  • Pathology usually congenital therefore not typically seen in adults
  • Left cusp is closest to the AV, anterior cusp furthest from AV — ME RV inflow-outflow shows AV in SAX = PV in LAX with anterior cusp in far field and R/L cusp closest to AV

Q

Pulmonic Insufficiency

A
Mild PI = normal variant
Significant PI usually congenital
May be acquired (carcinoid) but rare
Infective endocarditis least likely affects PV
Etiology:
•carcinoid
•endocarditis
•pulmonary hypertension
•myxomatous disease
•thorax radiation

Q

Pulmonic Insufficiency Grading

A

Similar to AI…

Jet area
Jet width
Holodiastolic flow reversal in main PA
•early velocity —> PA mean pressure
•late velocity —> PA diastolic pressure

Q

Pulmonic Stenosis

A

Usually congenital

Peak / Mean gradient with CWD

Subtract the max PS gradient from the RVSP to obtain the PASP
•CWD of TR jet —> RVSP
•RAP by central line CVP
•RVSP - PASP = PS pressure grad
... PASP = RVSP - PS pressure grad
