DCM / transplant

Question 1

dp/dt definition

Answer 1

Index of myocardial contractility
Time takes for LV to produce pressure of 32 mmHg
Longer time = worse

Question 2

dp/dt equation

Answer 2

= 32 / time in sec

Question 3

Normal dp/dt

Answer 3

> 1200

Question 4

Borderline dp/dt

Answer 4

1000-1200

Question 5

Abnormal dp/dt

Answer 5

<1000

Question 6

Relative wall thickness

Answer 6

2 x PWTd / LVIDd

Question 7

Normal LV mass index women

Answer 7

<= 95

Question 8

Normal LV mass index men

Answer 8

<= 115

Question 9

RWT >0.42, normal LV mass index

Answer 9

Concentric remodeling

Question 10

RWT <0.42, normal LV mass index

Answer 10

Normal

Question 11

RWT > 0.42, high LV mass index

Answer 11

Concentric hypertrophy

Question 12

RWT < 0.42, high LV mass index

Answer 12

Eccentric hypertrophy

Question 13

Markers for poor prognosis

Answer 13

Pulsus alternans in LVOT PW
DT < 115
Restrictive filling
RV dysfunction, pHTN
MR

Question 14

Isolated Non-compaction of LV definition

Answer 14

Altered myocardial wall with thin compacted layer and thick non-compacted layer (prominent trabeculation)

Question 15

Jenni criteria for LV non-compaction

Answer 15

Non-compacted to compacted 2:1, short axis, end systole
Color flow in recesses
Trabeculation meshwork typically in apex, inferolateral

Question 16

Chemo toxicity

Answer 16

10-15% decline in GLS predicts future events

Question 17

Signs of transplant rejection

Answer 17

Increased wall thickness, LV mass
EF reduced > 10%
Diastolic dysfunction (dec MV DT, dec E’, inc E/e’)

Question 18

RV biopsy complications

Answer 18

Effusions
VSD/ASD
TV dysfunction

Question 19

Sphericity index

Answer 19

Ratio of short-axis length (mid-ventricular) to long axis length
Less spherical with dobutamine = predictor of recovery for idiopathic DCM

Question 20

Aorta-mitral curtain thickening or calcification suggestive of

Answer 20

Radiation heart disease

Question 21

Echo features of HCM a/w SCD

Answer 21

Increased LV WT
LV dysfunction
LV apical aneurysm
Increased LA volume index
Restrictive filling
LVOT obstruction

Question 22

Hemochromatosis echo features

Answer 22

Mildly dilated LV cavity
Global dysfunction
Normal or mildly increased wall thickness

Question 23

Chagas echo

Answer 23

Normal LV size with apical aneurysm and LV thrombus

Question 24

Apical HCM features

Answer 24

LV apex >15mm

Apical to posterior wall thickness >1.5, absence of other etiologies of LVH

Question 25

LV non-compaction criteria

Answer 25

2 layers of myocardium visible Non-compacted to compacted >= 2 at end-systole Prominent trabeculations Deep recesses which fill with contrast / color doppler

Question 26

Most important echo predictor of mortality in AL amyloid

Answer 26

LV wall thickness

Question 27

Crypts suggestive of

Answer 27

HCM

Question 28

ARVD features

Answer 28

RV akinesia, dyskinesia or aneurysm RVOT dilatation Reduced RV FAC

Question 29

Paradoxical LVOT diastolic flow in HCM

Answer 29

Apical aneurysm / outpouching | Increased risk of SCD
