Upper figure
: transthoracic evaluation of mitral regurgitation associated with left ventricular systolic dysfunction (note reduced slope of velocity increase during isovolumic contraction), and elevated left atrial pressure.
Cuff radial pressure= 90 mmhg
LAPms= 90 - 57.2 = 32,8 mmHg. 

 

 

 

 

 


Lower figure
: transthoracic evaluation of mitral regurgitation associated with mild reduction of left ventricular systolic function and increased left atrial pressure.
Cuff radial pressure= 100 mmHg
LAPms= 100 - 67.6 = 32,4 mmHg
