Posts Tagged ‘tmt and lad disease’

A patient with near 90% LAD disease who had a significant TMT/EST positivity with no clinical angina  was  subjected to FFR by a scientific  cardiac physician. Since FFR was recorded as  .9 , he was adviced against a stent and sent home with drugs.

Now , in the  physiological assessment of a coronary lesion ,  which one you are going to trust , TMT positivity or FFR ?

FFR  measures trans-lesional pressure drop  by creating a artificial exercise physiology  in a particular coronary bed by injecting just one of coronary vasodilators  namely Adenosine. FFR assessment can never be considered truely  physiological .There has been huge discrepancy in the amount , rate and route of administration and the hyperemic response to Adenosine.

Final message

In a single vessel disease population , if TMT is positive the lesion is to be taken as significant, irrespective of FFR.(Provided Anemia and other systemic factors are excluded )

*Read this and get ready to get  confused further , single vessel disease with TMT positivity  doesn’t mean medical management is never an option .OMT ,(optimal medical therapy ) even though a battered concept is not yet dead for SVD !
