Pulmonic Valve

Question 1

PV Leaflets

Answer 1

R and left attached to septum, face AV

Anterior leaflet

Question 2

Severe PS Anatomy

Answer 2

Thickened leaflets, systolic doming, calcification

Question 3

PS causes

Answer 3

Congenital

Carcinoid

Question 4

Severe PS hemodynamics

Answer 4

peak velocity > 4
PG > 64
MG > 35
RVH > 0.4 cm
Post-stenotic PA dilatation

Question 5

Severe PS consequences

Answer 5

RVH (RV dilation should not be present in young with isolated PS)
Post-stenotic main PA enlargement
Possible RA/RV enlargement

Question 6

PR causes

Answer 6

Due to prior repair (TOF / PS)
Congenital
Endocarditis
Carcinoid

Question 7

Severe PR anatomy

Answer 7

Distorted or absent leaflets, annular dilatation

Question 8

PS appearance (all)

Answer 8

Systolic doming

Question 9

Infundibular pulmonic stenosis

Answer 9

RVOT obstruction

May cause high velocity jet that damages PV and causes PR
