A Comparative Study to Evaluate the Pre and Post-Operative Electrocardiographic and Echocardiographic Changes in Children with Tetralogy of Fallot Undergoing Modified Blalock–Taussig–Thomas Shunt Surgery

Key Points

• The study aims to evaluate the electrocardiographic and echocardiographic changes following shunt surgery in children with tetralogy of Fallot.
• Conducted a comparative evaluation pre and post-operative.
• Involved measurements of hemodynamics, ECG, and transthoracic echocardiography (TTE).
• Notable improvements in pulmonary blood flow were observed.
• Changes in hemodynamics and ECG parameters correlated with surgery.
