Why left heart border become straight in Mitral stenosis ?

Posted Apr 26 2012 10:59am

Here is an X-ray of classical rheumatic mitral stenois with a mitral orifice of  .8 square cm.

Why the left heart border is straight in mitral stenosis ?

It is due to 4 factors.

  1. Hypoplastic aorta
  2. LAA
  3. PA
  4. Under filled LV

Note :

  • This straightening occurs   only  in  isolated , severe forms of mitral stenosis  as it requires under filling of left  ventricle   and Aorta.
  • Significant mitral regurgitation will lift the lower end of straight line .
  • In associated aortic valve lesions especially in aortic regurgitation the straightening can not occur as LV and  Aorta continues  to be conspicuous.
  • If mitral stenosis  causes severe PAH and tricuspid regurgitation , RV  can  become  huge  and form the left heart border and distort the straight line.
