Table 9 Representative criteria for DEcho grading of LVDD.
Marker | DEcho Criteria | |||||
|---|---|---|---|---|---|---|
Grade 0 | Grade 1 | Grade 2 | Grade 3 | Grade 4 | ||
Normal Filling | Delayed Relaxation | Pseudo-Normal Filling | Reversible Restrictive Filling | Fixed Restrictive Filling | ||
Mitral Inflow E/A Ratio | LV Preload | ≥ 0.8 | ≤ 0.8 | > 0.8 to < 2.0 (Reversed on Valsalva) | > 2.0 (Reversed on Valsalva) | > 2.0 (No Reversal on Valsalva) |
Peak TR velocity: (Normal ≤ 2.8 m/sec) | RV & MPA Systolic Pressure | Normal | Normal | Abnormally Increased | Abnormally Increased | Abnormally Increased |
Associated level of LV diastolic pathophysiology | ||||||
LV Myocardial Relaxation | Normal | Mildly Impaired | Moderately Impaired | Severely Impaired | Severely Impaired | |
LV Myocardial Stiffness | Normal | Mildly Increased | Moderately Increased | Severely Increased | Severely Increased | |
LV Preload (i.e., mLAP) | Normal | Normal | Mildly Increased | Moderately Increased | Moderately Increased | |
LA Contractility | Normal | Normal | Normal | Decreased | Decreased | |
