                                                                              NOTES
-LAP = SBP - peak mitral Gdt        or        E / E' +4
-B-Bump => increased LAP/LVEDP in AR (prolonged closing of MV between A and C) in late diastole
-LV/LA gradient - Cuff BP = OT Gradient
-Tamponade: Inflow patterns - MV 25% - TV 35%
-LA Vol index>34 ml/m2 - is an independent predictor of death, CHF, AF and isch stroke (ref)
