The history should be available. I'm going
0:03
to play the
0:05
gonna show some still images here case number
0:08
four is actually a 54 year old
0:11
man.
0:12
With increasing Insurance of bread and NMR was
0:15
performed. They said three chamber view notice the left ventricle left
0:18
atrium right ventricle aortic route ascending
0:21
aorta.
0:22
And this is a oblique sagittal
0:25
view right ventricle harmonic artery.
0:29
Iotic Arch listening Iota right atrium. Now
0:32
I'm going to show some some cine images which are
0:35
very important in this particular case.
0:37
This is the three chamber View.
0:40
Notice the left ventricle right ventricle back
0:43
to Atrium iot Groot.
0:46
Just going to let that play for a minute.
0:49
And now we're going to see the oblique sagittal view
0:52
here. Actually this cine was what I wanted. So just
0:55
play within a minute when I show this me.
0:57
Okay. So this is the cine view right ventricle right
1:00
ventricular outflow tract goes the key images here. So
1:03
we have a combination now. I'm going to go back to the still images
1:06
because it's still images have most of the
1:09
information here. So here we have a 54 year
1:12
old man with increase Insurance of bread.
1:14
Three chamber View and oblique's natural
1:17
view of the right ventricles. The correct answer is five
1:20
choices here if we can put up the phone, please.
1:23
Yeah.
1:24
So it's five choices here. This is a congenital heart condition.
1:27
Is it a double Outlet right ventricle is a
1:30
great vessels transposed is the
1:33
isolated harmonic stenosis of the trunk is a trunk usarteriosis or
1:36
is a tetralogy of fallow.
1:39
So three chamber View and an oblique exchange of view
1:42
of the right ventricle or right 24 hour track view. Can we
1:45
have trunkus arteriosis unfortune?
1:48
That's not the right answer. The right answer is a
1:51
tetralogy of fallow notice all the features of
1:54
Technology of fellow present a Yota overrides the
1:57
right ventricle. There's this vsd ventricular separate defection
2:00
notice the defect in the septum. There is harmonic stenosis.
2:03
I'm going to show the cine again notice the
2:06
defacing the right ventricular outfit track and there's right ventricular hypertrophy
2:09
all the classical findings of Technology of fallow.
2:12
Trump is arteriosis when a single vessel arises from the
2:16
Arises from the heart and gives rise to the auto and
2:19
the pulmonic artery. This is not a case of Trancas arteriosis
2:22
doubled out. It's not a double Outlet right ventricle. It's
2:25
not the great verses are not transpose. There's not
2:28
isolated harmonics nurses a key findings in technology of
2:31
fallow. Once again, the city images. This is
2:34
the Sydney image notice the vsd aorta overriding
2:37
the two ventricles.
2:39
Okay findings of tetralogy of fallow.
2:42
and then on the
2:44
oblique sagittal view noticed the pulmonic stenosis
2:47
seen as defacing the right ventricular outflow tract
2:50
and consequent right ventricular hypertrophy key findings
2:53
of Technology of fellow.
2:55
Any questions before you before we go to the next questions
2:58
instead of questions based on a tetralogy of fellow. So
3:01
next question based on I'm just going to keep this keep this
3:04
up is falling primary and
3:07
tomical repair which of the following
3:09
Is the Communist hemodynamic complications technology of
3:12
fellow has to be repaired?
3:14
As it is a cyanotic congenital heart disease
3:17
and typical repairs performed by relief of
3:20
right ventricular off retract obstruction and by closure of the ventricular defect.
3:24
So following repair patients are not completely cured residual
3:27
hemodynamic effects can occur
3:30
and the Communist human Dynamic abnormalities is
3:34
one of the following one of the Five Below.
3:37
Tricuspid insufficient and that's not the right answer
3:40
the right answer. It's pulmonic insufficiency. So they're right answers d
3:44
Called Monica and sufficients. Yes strike us but insufficients in can occur but
3:47
that's not the primary abnormality user track us but insufficient secondary to
3:50
dilated right ventricle. So relief of our VO2
3:53
obstruction requires resection of the right ventricular output tract region
3:56
or all the pulmonic valve leaflets and
3:59
following resection of the right clinical
4:02
outflow attract either by a muscle bundle a section up harmonic
4:05
valve resection harmonic insufficiencies, the
4:08
key finding and that's the key hemodynamic abnormality after that after
4:11
correction of tetralgia fellow and a large volume
4:14
of adult congenital practices is follow-up
4:17
of patients with tetralogy of
4:20
calculation of research and function of harmonic registration.
4:23
And right ventricular volumes says as
4:26
the harmonic valve becomes insufficient the
4:29
right ventricle keeps dilating and at some point harmonic valve
4:33
repair and maybe needed to further
4:36
prevent irreversible RV
4:39
dysfunction. So harmonic insufficiency is a
4:42
key finding after a pair of techn.
4:44
Of the others can occur that can be some residual harmonics
4:47
nurses track husband insufficient of panaker, but it's usually secondary to
4:50
rvalitation. They can be residual vsds
4:53
iot growth can be dilated and based natural fellow, but
4:56
that's not the primary abnormality. The primary abnormality is pulmonic
4:59
insufficiency after a pair of tetralogy of
5:02
hello.
5:03
Question number three, so harmonic insufficiency can
5:06
occur and at some point right ventricle May Fail and
5:09
before that failure occurs, the harmonic valve may
5:12
need to be replaced either percutaneously or by surgical repair. So right
5:15
ventricular volumes are a key parameter to
5:18
monitor after repair of controls your
5:21
fellow and there is a threshold when it's considered that
5:24
harmonic ground replacement is needed. So question number three asks what
5:27
the threshold is can we put question number three
5:30
on please. So let me read out the question. So when when should
5:33
the harmonic boundary be replaced after repair of control
5:36
your fallow? Is it at 90 to 130 150
5:39
to 117 17200 or
5:42
250? Ml per square meter father right ventricular size.
5:45
The correct answer is 150 is
5:48
15.
5:50
So when the right?
5:53
When the right ventricular volume exceed 150 to
5:56
170 ml per square meter.
5:59
The harmonic valve should be replaced
6:02
that's considered the thresholds or repair
6:05
of tetralogy of fellow. So
6:08
after repair of tetralogy of fallow pulmonic
6:11
insufficiency is the primary hemodynamology
6:14
and serial MRIs
6:17
performed typically every one to three years and when
6:20
the right ventricle reaches 150 to 170 MLS
6:23
per square meter indexed.
6:25
For the pulmonic valve replacement is considered. It's
6:28
the control geofollow a common
6:31
the Communist cyanotic and general heart disease VST Toyota
6:34
overriding the right ventricle, right ventricular outfitractor abstraction
6:37
and write ventricular hypertrophy and atomic repair
6:40
consists of vsd patch repair and relief of
6:43
RV obstruction. The primary human Dynamic complication
6:46
adult survivors is residual harmonic insufficiency. Same
6:49
CMR cardiacomar is used
6:52
to guide the timing of common replacement which should be
6:55
performed before the right one of the severely dilated typically.
6:58
When the index and diastolic volume reaches 150
7:01
ml per square meter harmonic bound replacement is considered,
7:04
okay.
