The Unrepaired Tetralogy of Fallot: A Tale of Delayed Presentation and Limited Access to Care.

ABSTRACT

Tetralogy of Fallot (TOF) is a common cyanotic congenital heart disease characterized by four distinct anatomical features. While surgical repair has significantly improved long-term outcomes, some individuals, particularly those from low socioeconomic backgrounds who lack access to medical care, may suffer from complications such as pulmonary hypertension (pHTN) and heart failure. We present a case report of a young female with unrepaired TOF who presented with acute-on-chronic hypoxic respiratory failure and heart failure, highlighting the complex nature and challenges associated with this condition.
