Tetralogy of Fallot

Preamble

At times, the complexity of tetralogy of Fallot remains hidden, eluding detection for an extended period, often spanning several months to a year. The pursuit of identifying conditions such as tetralogy of Fallot becomes a pivotal objective during routine health assessments under the guidance of a medical practitioner. Should your child manifest a pallid, bluish hue, contend with respiratory distress, experience seizures, succumb to fainting spells, endure unexplained fatigue, or demonstrate sluggish developmental progress, it falls upon a healthcare expert to unravel the origins of these challenges.

If contact with your child's healthcare provider proves elusive, or if the child exhibits any of the ensuing symptoms, an immediate visit to the hospital's emergency ward becomes imperative:

• Cyanotic discoloration
• Respiratory impediments
• Seizure occurrences
• Loss of consciousness
• Profound weariness or feebleness

Domestic Care Considerations

In the event that your child commences a transition towards a cyanotic state, position the child supine, with their knees drawn towards their chest, and expeditiously summon emergency medical assistance via "911" or your local emergency contact number.

Subsequent Evaluation

Your designated healthcare professional should orchestrate periodic follow-up assessments for your child. During these appointments, the child's cardiac rhythm will undergo scrutiny, as children who have undergone surgical intervention for tetralogy of Fallot may develop anomalous heart rhythms.

Prospects and Prognosis

In the wake of a triumphant surgical procedure, children typically remain asymptomatic and lead lives characterized by normalcy, punctuated by minimal or non-existent restrictions. However, the surgical intervention itself may engender enduring complications. These encompass the subsequent possibilities:

• Right ventricular insufficiency: The potential for right ventricular insufficiency looms, particularly when surgical measures yield severe pulmonary valve incompetence, involving the retrograde flow of blood from the pulmonary artery into the right ventricle.
• Electrocardiographic anomalies: Each patient grappling with tetralogy of Fallot presents with a right bundle branch block resulting from the innate ventricular septal defect. However, the introduction of a patch into the ventricular septum can incite cardiac block or insufficiency, disrupting the intercommunication between the upper atria and lower ventricles. On occasion, a permanent pacemaker becomes a necessity.
• Cardiac Arrhythmias: Owing to surgical interventions targeting the ventricles, the subsequent emergence of postoperative ventricular tachycardia (VT) represents a rare yet perilous risk. Given its life-threatening nature, it is pivotal to remain vigilant in identifying the predisposition to ventricular tachycardia during postoperative follow-up evaluations.
• Lingering Perforation in the Ventricular Septum: The persistence of an aperture in the ventricular septum remains within the realm of possibility, allowing oxygenated blood to traverse from the left cardiac chamber to the right (shunting).
