Unlike the developed world where most of the patients with TOF<\/jats:styled-content> are corrected in infancy, average age of presentation and thus surgery for these patients in the developing world may be higher. We aimed to study the correlation between RV<\/jats:styled-content> function parameters such as tricuspid annular peak systolic excursion (TAPSE<\/jats:styled-content>), fractional area change (FAC<\/jats:styled-content>), and tricuspid annular peak systolic velocity (S\u2019) with early outcome variables after intracardiac repair for TOF<\/jats:styled-content>.<\/jats:p><\/jats:sec>Materials and Methods<\/jats:title>Fifty patients with a preoperative diagnosis of tetralogy of Fallot scheduled for corrective surgery were included in this single\u2010center, prospective observational study. A preoperative transthoracic echocardiogram was performed to measure RV<\/jats:styled-content> function parameters (FAC<\/jats:styled-content>0, TAPSE<\/jats:styled-content>0, S'0). Transthoracic echocardiography was repeated postoperatively to measure FAC<\/jats:styled-content>1, TAPSE<\/jats:styled-content>1, S'1 (day 1) and FAC<\/jats:styled-content>2, TAPSE<\/jats:styled-content>2, and S'2 (day 3).
