Tetralogy of Fallot, demystified


Tetralogy of Fallot is a fairly common heart defect. In fact, it's the most common cyanotic heart defect (meaning that if a baby is born with cyanosis - markedly decreased oxygen saturation - and the cause is determined to be a congenital heart defect, the most likely culprit is tetralogy of Fallot).

From the name, it’s obviously composed of four parts. But how to remember what those parts are? You could just memorize them using brute force, but there's actually one thing that ties them all together - so if you can remember this one thing, then the four things make sense. I love this, because when you find you've forgotten one of the four things (which you probably will), you can actually reason it out. Hurray!

Here's the one thing to remember, and it's actually the thing that causes the whole disease. When the interventricular septum is forming, the top portion is pushed up and towards the right ventricle. The official name for this is anterosuperior displacement of the infundibular septum, but it's easier to just remember "up and towards the right," I think.








Check out this image of tetralogy of Fallot. See the red asterisk? That's the top of the interventricular septum. The black asterisk marks the bottom of the interventricular septum. Those parts are supposed to be connected...but obviously they're not. And the reason they're not is that the top part of the septum has moved up (creating a hole in the septum) and to the right (smushing the pulmonary artery outflow tract).

So what happens as a result?

One of the main problems is that it's now very hard for the blood to get out of the right ventricle and into the pulmonary artery (and lungs). That's because the pulmonary outflow tract (fancy name for the beginning of the pulmonary artery) is compressed, and there's less room for blood to flow through. This is called pulmonary stenosis. This is what causes the baby to be cyanotic! If you can't get enough blood out into the lungs, the blood isn't going to be oxygenated very well, and the baby's skin will be bluish. The right ventricle has to work hard to push blood through that compressed pulmonary artery - so the right heart becomes hypertrophied (bigger).

A couple other things happen too, as a result of this displacement of the septum. As the top part of the septum moves upwards, it separates from the bottom part, creating a hole in the septum (this is called a ventricular septal defect). This is actually kind of a good thing, in this case, because it relieves a little of the pressure on the right side of the heart. If the septum was intact, then the only place for the right ventricular blood to go would be through the compressed pulmonary artery...and the right ventricle would have to work incredibly hard to empty itself with each cardiac cycle.

Finally, as the top part of the septum moves to the right, it pulls the aortic valve along with it, repositioning it so that it sits pretty much right over the ventricular septal defect. This is called an overriding aorta, and it doesn't have much clinical consequence.  

So to summarize: the top of the septum moves up and to the right, causing:
1. Pulmonary stenosis 
2. Right ventricular hypertrophy 
3. A ventricular septal defect
4. An over-riding aorta

Blood Transfusion

THE RIGHT WAY OF ADMINISTERING BLOOD PRODUCTS

[ from "THE CLINICAL USE OF BLOOD: HAND BOOK , World Health Organization & Blood Transfusion Safety , GENEVA ]

✔️Prefer a larger cannula: A doubling of the diameter of the cannula increases the flow rate of most fluids by a factor of 16.

✔️In case of Whole blood, red cells, plasma and cryoprecipitate
>Use a new, sterile blood administration set containing an integral 170–200 micron filter

>Change the set at least 12-hourly during blood component infusion
>In a very warm climate, change the set more frequently and usually after every four units of blood, if given within a 12-hour period

✔In case of Platelet concentrates

>Use a fresh blood administration set or platelet transfusion set, primed with saline.

✔️WARMING BLOOD:

>There is no evidence that warming blood is beneficial to the patient when infusion is slow.

>At infusion rates greater than 100 ml/minute, cold blood may be a contributing factor in cardiac arrest. However, keeping the patient warm is probably more important than warming the infused blood.

>Warmed blood is most commonly required in: [1]Large volume rapid transfusions:
    -Adults: greater than 50 ml/kg/hour      -Children: greater than 15 ml/kg/hour
[2]Exchange transfusion in infants  [3]Patients with clinically significant cold agglutinins.

>Blood SHOULD ONLY BE WARMED in a blood warmer. Blood warmers should have a visible thermometer and an audible warning alarm and should be properly maintained.

>Blood should never be warmed in a bowl of hot water as this could lead to haemolysis of the red cells which could be life-threatening.

✔️Severe reactions most commonly present during the first 15 minutes of a transfusion. All patients and, in particular, unconscious patients should be monitored during this period and for the first 15 minutes of each subsequent unit.

✔️The transfusion of each unit of the blood or blood component should be completed within four hours of the pack being punctured. If a unit is not completed within four hours, discontinue its use and dispose of the remainder through the clinical waste system.

Abscopal Effect

Splenectomy is an effective secondary or tertiary treatment for two chronic B cell leukemias, hairy cell leukemia and prolymphocytic leukemia, and for the very rare splenic mantle cell or marginal zone lymphoma.

Splenectomy in these diseases may be associated with significant tumor regression in bone marrow and other sites of disease.

Similar regressions of systemic disease have been noted after splenic irradiation in some types of lymphoid tumors, especially chronic lymphocytic leukemia and prolymphocytic leukemia.

This has been termed the abscopal effect. Such systemic tumor responses to local therapy directed at the spleen suggest that some hormone or growth factor produced by the spleen may affect tumor cell proliferation.

TRALI

TRALI ( Transfusion related acute lung injury )
1. Definition - it is acute lung injury which occurs within 6 hours of completion of transfusion of blood components.
Pathogenesis - two hit hypothesis.
First hit is the priming event like endothelial activation which leads to increased sequestration and
sensitisation of neutrophils in the micro vasculature of lung. Second hit can be the antibodies in
the transfused blood product that recognise antigens expressed on neutrophils. Most common
antibodies can be those that bind MHC antigens.
2. TRALI can occur with all plasma containing products but more common with transfusion of FFP and platelets.
3. Clinically - dyspnea, tachypnea, fever, hypotension.
4. Chest X Ray - bilateral pulmonary infiltrates or white out lung. That is why most important differential diagnosis is ARDS.

6) titration studies.



?☺: Tumor Lysis Syndrome

* Most commonly seen with acute leukemias, Burkitt lymphoma and other lympho-reticular malignancies (uncommon in solid tumors).
* Chemotherapy results in death of large quantities of cells, which leads to release of massive amounts of potassium, uric acid and other breakdown products into the blood.
* It develops within hours to few days of initiation of chemotherapy.

* Features:
- hypocalcemia
- renal failure due to precipitation of uric acid crystals or calcium phosphate crystals in the kidney
- hyperkalemia leading to arrhythmias
- hyperphosphatemia

* Management
- vigorous IV hydration with half normal saline
- correction of metabolic abnormalities
- hemodialysis in severe cases
