Tetralogy of Fallot (TOF): Pre-Op & Post-Op Care

Pre-operative Assessment:

Clinical assessment: The degree of cyanosis is the most important aspect of clinical evaluation. Measuring oxygen saturation by pulse oximeter is recommended at each follow-up examination. ECG determines the and chest X-rays are taken to evaluate the overall shape of the heart. An echocardiogram stands as a vital tool for the diagnosis of TOF.

Surgical Procedure:

• Complete corrective Tof surgery is usually performed before 6 months of age as open intracardiac surgery performed under cardiopulmonary bypass conditions in one operation. 
• During surgery, the heart is exposed via a median sternotomy and a RVOT reconstruction with a patch to close the defect at the time of initial repair.
• The tetralogy of fallot repair surgery involves patch closure of the VSD (ventricular septal defect), septating the aorta back to the left ventricle, resection of RVOT (right ventricular outflow tract) muscle bundles, and reduction of the degree of RVOT valvular stenosis.
•  A transannular patch may be required to sufficiently enlarge the RVOT and the patch may be used at multiple levels to facilitate the repair.

Post Operative Care & TOF Repair Recovery:

• After repair, early postoperative management is in paediatric intensive care.
• The postoperative course is variable depending on the age of the child, duration of cardiopulmonary bypass, the type of ToF repair, and other associated co-morbidities.
• All children and adults will be under lifelong follow-up with congenital heart disease services. However, it is recognised that compliance with follow-up can be poor, and some patients can be unaware of their diagnosis.
•  On emergency presentation or before elective surgery, consultation should be had with the regional paediatric or adult congenital cardiac centre. 

Benefits of Tetralogy of Fallot (TOF) at Yashoda Hospitals

• Correcting ToF allows better blood flow to the lungs
• Surgery repairs structural defects in the heart, ensuring efficient circulation and reducing strain on the heart muscle.
• Addresses the stunted growth and delayed development due to low oxygen levels
• helps restore normal growth patterns and activity levels.
• After successful repair, children can engage in regular activities without experiencing fatigue or breathlessness.
• Timely surgical intervention reduces the risk of severe complications like heart failure, arrhythmias, and brain abscesses.
• Early surgical correction significantly improves life expectancy and quality of life, allowing children to lead healthy, active lives.
• Repairing ToF lowers the likelihood of frequent hospital visits and emergency interventions due to heart-related distress
