My max LV aorta Gradient was 6 mm/hg

  Mine is   6 mm/hg  at a  resting echo    

What  does this mean  in terms of  significance or risK

Any  help on this welcomed

Many  thanks for the   explanation.     I  suppose my final  question that  flows from the  very  helpful information  you have kindly  provided, is whether  when exerting oneself  this  turbulence presents  any inherent  risks  ?
I am presuming I have had  this since  childhood  because I have always been noted  to have a murmur,  described overall as  'soft'   sometimes grade  2  out  of  6     I  guess this  soft  murmur corresponds  to the low  gradient  
and  it being lifelong probably means its  just 'one of those  things'  rather  than anything to worry about
My only symptom of  concern to me  is a tendency to feel out of breath on drinking alcohol

As I previously posted the most common causes for LVOT turbulence are associated with the aortic valve morphology (e.g. mild fusion of 2 leaflets of the valve, bicuspid valve, unicuspid valve, thickening of the leaflets). If your aortic valve is normal, a subaortic membrane is the second most common cause for LVOT turbulence/obstruction (8–30% of cases). In your case, whatever is causing this turbulence is not generating a significant stenosis/gradient (only 9 mmHg). Sometimes, the surface echo is not able to discriminate what is causing the turbulence, especially when the cause is a small membrane or a small leaflet fusion.
The fraction shortening is the difference between the end diastolic and the end systolic diameter of the left ventricle in the parasternal long axis of the echo FS= [(end-diastolic - end-systolic) / end-diastolic] x 100 (%). That value is not clinically used (although in your case is also normal), only the ejection fraction is useful.

Thank you  for the information.    What  I am trying to  find out  is  why I have turbulent  flow at the LVOT       If  my  aorta is normal and  no issues there    Said not to be stenosis,  and my  LV  is not   really  hypertrophic, and I have a audible murmer  at the lower  left  sternal  edge my whole life,  then what on earth  can be the possible causes  of the  turbulent  flow   and indeed  presumabltyt  turbulent  flow  may not  ovber a  period of many years come  without  consequences.   The other bits I  don;t  underastand  is 'fractional  shortening '  of  43  per  cent      My  ejection fraction is 74  per cent.
The  turbulent flow  seems  to usually go with some pathology or other  ?

The LV/aortic gradient usually refer to the difference of pressure between the left ventricle and the aorta in systole (when the heart is ejecting). A value of 6 mmHg for this gradient is low/nonsignificant, so has no risk involved.

Good luck
