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
