Long-Term Management of Right Ventricular Outflow Tract Dysfunction in Repaired Tetralogy of Fallot

Published: November 21, 2024

  • Tetralogy of Fallot (TOF) is the fifth most common form of congenital heart disease and the most encountered cyanotic lesion. Contemporary early survival following infant surgery is approximately 98% with 25-year survival of over 90%.
  • Surgical reconstruction of the right ventricular outflow tract (RVOT) during TOF repair (rTOF) often results in pulmonary regurgitation, stenosis, or both. These anatomic and functional derangements trigger a complex, slowly progressive pathophysiologic cascade that ultimately results in adverse clinical outcomes, including heart failure, arrhythmias, and premature death.
  • Long-term surveillance of patients with rTOF is critical to anticipate and proactively manage complications. Multimodality testing is recommended periodically, and its frequency is tailored to symptoms and severity of illness.
