Conclusion
In conclusion, the feasibility of the individual diastolic parameters
was excellent, except TR Vmax and pulmonary venous flows. Overall, the
algorithm in the 2016 guidelines was superior to the 2009 algorithm in
terms of its precision in classifying patients (i.e., fewer
indeterminate cases) and subsequently classifying patients in a uniform
matter (i.e., fewer re-classifications). The 2016 algorithm proved more
restrictive than 2009 in classifying patients with advanced stages of
DD.
