Cardiac MRI Case 9

HIDE
PrevNext

0:00

We're going to review approximately 12

0:03

cases today cardiacomark cases

0:06

that we see in routine clinical practice. They are

0:10

labeled 13 on words because this is a continuation of of a

0:14

session that was started a couple of weeks ago first

0:17

case here. We have

0:20

a four chamber Sydney image here that's playing and it

0:23

belongs to a young woman who has an erythria.

0:25

But there's two videos here and they're going to be followed by a question.

0:28

This is a fort chamber Sydney. It's bright blood

0:31

gradient. Echo image.

0:34

And the history is a young woman with an

0:38

arrhmia. It's a four chamber cine image a

0:41

great Echo steady state repossession the standard cine

0:44

Imaging used for cardiac MRI a

0:47

steady state free processions integrating Echo image, four chamber

0:50

View, and now I'm going to go to a short

0:53

axis View.

0:55

And here is the shot axis view.

0:58

This is the short axis View.

1:00

And I'm going to minimize this and once again

1:03

bring up the four chamber view. We'll let the fort chamber view play and

1:06

we're going to answer the questions. Okay, so based

1:09

on these two images. I'm going to I'm going to let this for chamber cine

1:12

play this three questions. Can I request the

1:15

first question to be put on please?

1:17

So the correct diagnosis is one of these for a geographic dilated cardiomark

1:20

the hypertrophic cardiomyopathy myocarditis arvd

1:23

or sea which stands for earthmogenic right ventricular

1:26

dysplasia and cardiac sarcoidosis. And

1:29

can I request the participants to to vote on

1:32

what they think is the best diagnosis 14 basini image

1:35

in a young patient with arrhythmia.

1:37

Okay, six or seven percent of the participants bull

1:40

for idiopathic DCM and 33 for

1:43

an arvc. We point out to the abnormality here

1:46

notice that the right ventricle has an area of this kinetic

1:49

wall motion notice that there's an aneurysm in

1:52

the right ventricular free wall anterior free. Wall right there. This portion

1:55

of the right to ventricle being pointed to is not moving properly. It's

1:58

moving outwards. It's aneurysmal.

2:01

That indicates that there's a abnormal right ventricle and it

2:04

shows an area of aneurysm aneurysm of

2:07

annotation and movement disconnected area furthermore

2:10

on the short axis view, which I'm going to pull up

2:13

in a minute here. You see a still picture here in the

2:16

short axis view. The right ventricle is dilated. It's bigger than the left ventricle.

2:20

Furthermore this is the systolic image of the four chamber

2:23

view notice the akinetic region. So actually it's

2:26

disconnected. It's moving outwards in Sicily. That's a

2:29

diastolic frame. That's a systolic frame. You see it's moving outwards indicating

2:32

that it's aneurysmal. The right ventricle is

2:35

dilated. These are features which support the presence of arvc earthmogenic

2:38

right ventricular cardiomyopathy and for

2:41

a diagnosis of air we see a kinesia disk and

2:44

easy of the right vertical is essential by 2010 task

2:47

force criteria and you see the disconnect area and the

2:50

right ventricle in the entry of free wall and the patient has

2:53

a diagnosis of arithmogenic right ventricular dysplasia. Can we

2:56

see the next question? Please pertaining to this case which of

2:59

the following abnormalities a prerequisite for Mr. Fulfillment

3:02

of diagnostic criteria for arvd we have

3:05

five choices here as a participants to vote

3:08

for the best one choice, please.

3:11

Okay, excellent. The majority of the participants answered

3:14

the poor correctly. Akinesia dyskinesia this

3:17

synchronous contractions essential for the diagnosis of arvc. And

3:20

in addition to that one must either have

3:23

a dilated right ventricular depressed rvjection fraction and the

3:26

degree of RV dilatation depends on on whether

3:29

a major criteria used or where they're minor criteria is

3:32

used. It's whether it's a man or a woman in in a

3:35

man in a notched out right ventricular over 110.

3:38

Ml commit square and a woman a hundred.

3:41

Ml per meter Square meets major criteria for RV dilatation

3:44

and injection fraction less than 35% meets

3:47

criteria for for a major Criterion, but

3:50

suggests that the audience refers to their 2010

3:53

updated task force criteria for arvc.

3:56

The finding of I'm going to once again show the four chamber

3:59

view here a can easier discarnation desynchronous

4:02

RV contractions, as you can see in the entry free wall

4:05

of the right ventricle essential for the diagnosis of arvc this

4:08

patient carries a diagnosis of arvc the last

4:11

question pertaining to this case. Can I ask for the poem please?

4:14

Okay, which of the following statements is incorrect? So

4:17

we're looking for an incorrect question incorrect statement

4:20

regarding arvd. Okay, the wrong statement a

4:23

normal cardiacom are excludes diagnosis RVC.

4:26

That's that's a wrong statement patients the diagnosis of

4:29

arvc depends on a number of criteria, which can be derived from

4:32

either genetics ECG family history morphological

4:35

abnormalities, which are diagnosed by

4:38

MRI or

4:41

genetic abnormalities. So in MRI can be normal in arvc yet

4:44

the patient may fulfill criteria for air VC based on

4:47

other criteria. For example, ECG criteria arithmic criteria

4:50

family history genetics.

4:53

So MRI can be normal but a normal

4:56

MRIs is a good prognostic feature in patients with arvc on the

4:59

contrary. If the MRI is extremely abnormal abnormal left

5:02

ventricular function very severely dilated right ventricular

5:05

extensive fibrosis or aneurysms. That's a

5:08

bad prognostic Factor feature and it indicates that the

5:11

patient may likely need an ICD which prevents certain cardiac deaths.

5:14

So the major concern for arv in arvc is sudden

5:17

cardiac death arithmia and certain cardiac death ventricular. Arithm is

5:20

the presence of RV acanisha disc

5:23

on each or disc synchronous contractions as seen in this case essential for

5:26

the diagnosis of arvc. So this case a long

5:29

story patient with arvc or arvd. We

5:32

increasing their fairing to AR VD as arvc because

5:35

we know it's a it's recognize the cardiomyopathy which

5:38

can involve both the right and left ventricles and end stages

5:41

are in some cases are in early case Aries. We see can

5:44

enroll the left ventricle. It's fact in the more

5:47

recently. It's being referred to as earthmogenic cardiomyopathira than

5:50

earthmogenic right hand because left ventricular.

5:53

And also being recognized or in the

5:56

end stages a left ventricle can also be involved arvc first

5:59

case. We've gone to the next case here.
