Predictors of Adverse Outcomes
Endocarditis
|
Aortic valve
>10mm
vegetation (Increased risk of embolization)
TV- generally
good prognosis
|
Cardiac
amyloidosis
|
DT < 150 ms
Other less validated markers of worse prognosis: LV wall thickness > 15 mm, RV enlargement |
Peripartum Cardiomyopathy
|
LVEF < 30 %
LVEDD ≥60mm
Elevated troponin
??Abnormal dobutamine
stress predicts recurrence
|
Cardiomyopathy
|
RV dysfunction
Sphericity index < 0.76
Diffuse hypokinesis
(RWMA more favorable prognosis)
Chemotherapy induced
CM (worse prognosis compared with idiopathic)
|
Pericardiectomy
|
Post radiation (worst
prognosis)
**idiopathic- best
prognosis
|
LV thrombus (risk for
embolization)
|
Large pendulous
thrombus (>0.8cm2 )
Mobile thrombus
|
Post MV repair
(Risk of SAM)
|
Co-aptation to septal
distance (C-sept) < 2.6 cm Posterior mitral valve leaflet height > 1.5 cm
Anterior leaflet/Posterior leaflet height ratio (AL/PL) < 1
Aortic Mitral angle < 130

Changes seen in rejection post transplant
Impairment of diastolic function:
-
Decrease DT >20%
-
Decrease in IVRT >20%
-
Increase in E velocity
New onset MR
>10% decrease in ejection fraction
Increased wall thickness >4mm (IVS + post wall)
Increased myocardial echogenicity
New/increasing pericardial effusion
