Q

Management of transposition of great vessels:
* procedure of choice in the 1st weeks of life
* reestablishes normal circulation with the L ventricle
acting out as the systemic pump
* transecting great arteries and anastomosing the main
pulmonary artery just above the aortic valve and
anastomosing the ascending aorta to the proximal
pulmonary artery
* coronary arteries switched from proximal aorta to the
proximal pulmonary artery

Management of Tricuspid
Atresia:
▪ Uses an intracardiac right atrial baffle, directing blood from
the inferior and superior vena cava to the pulmonary
arteries bypassing the right atrium and right ventricle.
▪ The TCP is used for patients with heart chambers which
allow recirculation and stagnation to occur

Q

Management of HLHS:
performed when an infant is 4 to 6 months of
age. This procedure creates a direct connection between the
pulmonary artery and the vessel (the superior vena cava)
returning oxygen-poor blood from the upper part of the
body to the heart. This reduces the work the right ventricle
has to do by allowing blood returning from the body to flow
directly to the lungs.

Q

Management of transposition of great vessels:
* Operative choice in infants with TGA, VSD and severe PS
* Involves: (1)closure of the VSD with a baffle directing L
ventricular blood through the VSD into the aorta and,
(2)closure of the pulmonic valve and placement of a
conduit from the R ventricle to the pulmonary artery
requires multiple conduit replacements as the child
grows
* An operation for repair of complete transposition of the great
arteries in association with a large VSD and pulmonic stenosis,

BROCK PROCEDURE –

33
Q

condition in which
the heart can’t pump enough blood to meet the
body’s needs. It may develop over time because
the right lower heart chamber (ventricle) is
pumping under higher pressure than usual. The
strain may make the muscle of the right ventricle
stiff or weak.

Heart failure

old

BALLOON ATRIAL SEPTOSTOMY
(RASHKINDPROCEDURE)

40
Q

Management of HLHS:
This procedure usually is done sometime during the period
when an infant is 18 months to 3 years of age. Doctors
connect the pulmonary artery and the vessel (the inferior
vena cava) returning oxygen-poor blood from the lower part
of the body to the heart, allowing the rest of the blood
coming back from the body to go to the lungs. Once this
procedure is complete, oxygen-rich and oxygen-poor blood
no longer mix in the heart and an infant’s skin will no longer
look bluish.

A

Fontan procedure

41
Q

Management of Tricuspid
Atresia:
▪ Uses an extracardiac conduit, taking blood from the inferior
vena cava directly to the pulmonary arteries,thus bypassing
the right ventricle.
▪ This allows the patient to still utilize the pumping power of
the right atrium.

NURSING DIAGNOSES FOR CYANOTIC HEART DEFECTS

A
  • Decreased CO related to developing CHF
  • Altered nutrition (less then body requirement) related to dyspnea and fatigue
  • Activity intolerance related to cyanosis and dyspnea on exertion
  • Altered growth and development related to hypoxemia
48
Q

Management of Tricuspid
Atresia:
➢ Preferred in very small babies - below 2 years of age - in
whom the lung vessel resistance is still quite high, and in
borderline cases with abnormal pulmonary arteries.
➢ This is a shunt from SVC to the pulmonary artery (the first
shunt is removed at the second operation).
