The next case belongs to patients who have had
0:03
cardiac surgeries. There's four different types of surgeries here
0:06
shown.
0:07
And four different patients with four
0:10
different types of surgeries, and these are all post-operative
0:13
Mr. Examinations and based on the post-operative appearances.
0:16
I'd like for the audience to make
0:19
a to come
0:22
to conclusion as to what what the patient
0:25
was probably born with in terms of the congenital defect. So, let's
0:28
have the polling questions while we look at these cases, please.
0:32
Okay, so the four choices are either repetitology or
0:35
fellow.
0:35
A arterial switch procedure done
0:38
for dtga or in atrial switch procedure done
0:41
for dtag, which stands for detranspose great
0:44
arteries or a Fontana procedure. I'm going
0:47
to I'm going to show these four cases first and then we will go
0:50
through we'll take a pull and show these and discuss the answers case
0:53
a
0:55
the patient may have had either of these following procedures
0:58
only one.
1:00
This is case b.
1:03
Case C and lastly case D. So
1:06
let's start with case a let's take a poll
1:09
of what the audience thinks the patient.
1:11
May have had done for their congenital heart defect.
1:14
Okay, RTL switch procedure accident very educated
1:17
audience. As far as congenital heart disease is concerned notice
1:20
the pulmonary arteries are draped in front of the auto what's
1:23
known as Napoleon's hat the coronary arteries seem to
1:26
have a rising. Abnormally. The left is has an
1:29
entire course seems realizing slightly towards
1:32
on a clock. It's arising more towards the love
1:35
the clock a position of the ten
1:38
o'clock position rather than expected. The aortic root is dilated this
1:41
particular configuration. The pulmonary artery is being in front of the aorta draped
1:44
over his typical for an arterial switch procedure known as
1:47
a comment.
1:49
This patient was born with a transposition of the
1:52
great entries.
1:53
Implying the authorized from the right ventricle the pulmonary
1:56
arteries arose from the left ventricle and they were switched when they
1:59
switched the coronary artery is also switched and the
2:02
crony obstruction or kinking is a complication this procedure
2:05
for the more iotic root dilutations are complications procedures
2:08
can be seen in the third is in the third image here
2:11
the typical finding of pulmonary arteries depross
2:14
the aorta in front of the OTA as a finding
2:17
for an arterial switch procedure. This can
2:20
lead to the complication of pulmonary artery stenosis common is complications after arterials
2:23
which are our YouTube obstruction stenosis iot
2:26
crude delegation and Crone reality obstruction.
2:29
But the this this picture on
2:32
the left showing the pulmonary arteries
2:35
across the ascending Toyota is a typical
2:38
finding for an arterial switch procedure has been performed for
2:41
Day transposition of the great arteries.
2:44
Okay case number B a case b can we
2:47
have a polygen please? This patient has had a surgical procedure
2:50
for
2:51
congenital heart disease and which surgical procedure
2:54
and which control heart disease?
2:56
Can the audience um, take a poll take
2:59
a walk again? Okay, the question, unfortunately, neither
3:03
of the water's got the correct
3:06
answer here. The correct answer is C atrial switch
3:09
procedure for transposition of the great arteries notice
3:12
that this the right ventricle is dilated. This
3:15
track has been insufficiency. The pulmonary veins
3:18
are draining into the right side of the heart. So this patient was
3:21
also born with a transpositional great arteries as in the previous patient
3:24
of the in up to
3:27
the 1990s early 1990s. The surgery that
3:31
was performed for an arterial switch was an atrial switch procedure. So
3:34
instead of switching the great arteries what the surgeon has
3:37
done here is connected the pulmonary veins to the right side
3:40
of the heart. So the the Palm ravenous blood goes in the
3:43
right atrium right ventricle and the right ventricles connect to the aorta. So
3:46
the right vertical functions as a systemic ventricle and
3:49
because it's it's functioning against high blood pressure it
3:52
eventually fails. That's what leads to the right
3:55
clinical advantage.
3:56
A good station. This patients had an atrial
3:59
switch procedure. The SVC has been baffled
4:02
into the left side of the heart notice that this patient
4:05
has svcs stenosis a typical location for baffle obstruction lower
4:08
end of the SVC common location for Superior as
4:11
we see to left atrium baffle obstruction.
4:14
This patients had an atrial level switch for transposition
4:17
of the great entries. The complications here are right
4:20
ventricular validation track has been sufficiency and stenos
4:23
in the lower SVC. You can see the pulmonary veins
4:26
can be seen draining to the right side of the heart as we see goes
4:29
into the left side of the heart atrial switch procedure for transposition the
4:32
great entries not commonly performed in this current
4:35
ERA. However, there will be a significant number of survivors of
4:38
the atrials which procedure that present for MRI. The role
4:41
of MRI is to evaluate the venous baffles and the
4:44
function of the ventricles spreading the right ventricle, which is
4:47
still connected to the aorta. Okay case numbers
4:50
see this patient has had a surgery
4:54
for congenital heart disease and the type of surgery performed
4:57
can be
4:58
Can be figured out from
5:01
these pictures the correct answer will be either one
5:04
of the following.
5:06
Okay, good, excellent Fountain procedure. This patient
5:09
has a single ventricle notice that there's a single ventricle in
5:12
this patient not too ventricles the SVC and
5:15
ivca connected directly the pulmonary arteries. The single
5:18
ventricle is connection to the aorta. This patients are the four-time procedure
5:21
total Cave of pulmonary connection commonly out
5:24
is connected directly to the SVC and IVC and the single
5:27
ventricle functions as a systemic ventricle and connected to
5:30
the aorta. This has patients headache Fontan procedure for
5:33
single ventricular hypoplastic left-hand syndrome in
5:36
this particular case.
5:38
Case number G. There's only one right answer
5:41
now.
5:43
This these MRI images belong to a patient has had
5:46
a heart surgery in the past.
5:48
And the correct, correct?
5:51
And so would be either of these four what has this patient
5:54
had.
5:55
Okay to charge your fellow repaired excellent the abnormalities
5:58
shown a dilated right ventricle. The
6:01
outflow tract region of the right clinical is very thin and discard
6:04
patients had an outro attract patch for
6:07
relief of pulmonary outflow tract obstruction and was
6:10
born with tetralgia fallow harmonic insufficiency is
6:13
the major residual hemodynamic effect in survivors of tetralogy of
6:16
fallow that leads right ventricularization the patch
6:19
and the outflow track region, which was repaired maybe scarred notice
6:22
the scarring in the right 24 hour track daily features
6:25
of repair technology of fellow.
6:28
So full cases for diagnosis technology of fellow Fountain procedure
6:31
atrial switch for translational
6:34
grade arteries and arterial switch for transpositional great
6:37
arteries all very common and important
6:40
indications for referral to adult kitchen hard disease practices
6:43
and MRI in particular because MRI can
6:46
clearly evaluate intercontiac and extra cardiac structures
6:49
for anatomy physiology Form and Function in patients
6:52
with prepared congenital heart disease a class one
6:55
indication a very important indication of economic MRI.
