AbstractObjective: To study the in-hospital outcome and short term outcomes in patients undergoing delayed total surgical correction for Tetralogy of Fallot.
Methods: A retrospective descriptive study with the above objective was conducted at our institute using data from the hospital records. Study included all the patients above the age of 13 year undergoing surgery for Tetralogy of Fallot from January 2016 to December 2017.
Results: A total of 85 patients, 56(65.9%) males and 29(34.1%) females, undergoing complete repair of TOF were identified with a mean age of 17.53±4.59 years. Two patients had undergone previous Modified Blalock- Taussig Shunt. Complications noted in the postoperative period were low cardiac output syndrome 17.64%, re intubation 2.4%, reoperation for bleeding 10.6% and free pulmonary regurgitation in 34 (40%) patients recieveing Transannular patch without
monocusp. On follow up, only 6 patients (7.1%) had significant pulmonary regurgitation. 30–day mortality was 2.35%. The postoperative outcomes depend mainly on the degree of preexisting cyanosis (p=0.048) and degree of right ventricular outflow obstruction(p=0.042).
Conclusion: Complete correction of Tetralogy of Fallot must be performed irrespective of the age at presentation. Long-term studies are required to study the late outcomes in this group of patients.
