Valvular

Pulmonic valve stenosis

PATHO

• Usually congenital

• PV stenosis ➔ right ventricular outflow obstruction ➔ ↑ right side pressure ➔ RVH

SSX

• HF sx

• Wide splitting of S2 (prolonged RV systole ➔ later closing of pulmonic valve)

• Systolic murmur that doesn't radiate (like AS) ± ejection click

DX

• ECHO

• Enlarged pulmonary artery on CXR

TX

• Balloon pulmonary valvuloplasty transcatheter dilation
