Conventional use of trans-annular patch (TAP) to release right ventricular outflow tract (RVOT) obstruction during repair of tetralogy of Fallot (TOF) may cause pulmonary regurgitation which may tell upon the life. There are multiple options to approach RVOT obstruction and spare the pulmonary valve (PV) function. This prospective cross sectional study was conducted in the department of Paediatric Cardiac Surgery, Bangladesh Institute of Child Health (BICH), from January 2015 to December 2016 to assess the short term effects and outcome of repair of TOF. All the cases enrolled by purposive sampling were categorized into 2 groups. The groups were labeled as group I and group II. Among 75 patients 50 patients were labeled as group I and rest 25 patients as group II. The cases of group I underwent intracardiac repair of TOF with TAP and that of group II without TAP. Data were collected and analyzed, p value was determined significant at <0.05. The post operative period of all patients went uneventful. There was no statistically significant difference in the post operative ICU care, complication rate and morbidity between two groups. There was no mortality. Irrespective of the modality of treatment, with or without TAP, this study observed a short term better outcome of primary repair of TOF.. Patients’ compliance was good with some acceptable complications.
