Final Answer:
Most structural disorders after tetralogy of Fallot repair involve pulmonary regurgitation.
Step-by-step explanation:
Tetralogy of Fallot (TOF) is a congenital heart defect characterized by four abnormalities in the heart's structure. Surgical repair is typically performed early in life to correct these abnormalities. After repair, one of the common long-term issues is pulmonary regurgitation, where blood leaks backward from the pulmonary artery into the right ventricle during diastole.
Pulmonary regurgitation occurs due to changes in the pulmonary valve after surgical correction. The regurgitation can lead to right ventricular dilation and dysfunction over time. While advancements in surgical techniques have improved outcomes, the long-term consequences of pulmonary regurgitation remain a concern. Regular follow-up and monitoring are essential to assess the severity and progression of pulmonary regurgitation, guiding decisions on when intervention may be necessary.
Understanding the specific structural issues post-TOF repair is crucial for managing patients effectively. Pulmonary regurgitation is a known and expected complication that healthcare providers need to monitor closely to optimize the care and outcomes of individuals who have undergone surgical correction for tetralogy of Fallot.
