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.
