Short-Term Outcomes Following Total Correction of Tetralogy of Fallot in Adult Patients

Objectivs: Tetralogy of Fallot (TOF) is a common congenital heart disease which should be corrected. The recommended time for the Tetralogy of Fallot Total Correction (TFTC) surgery is during the infancy for the possible difficulties during the surgery and the related issues. However, sometimes TOF is diagnosed and managed during the adulthood. Methods This study is a descriptive and retrospective one which included all patients who underwent TFTC at age of 15-year and older in a 10 -year period (between the years 2010 and 2020) to identify short-term (including in-hospital mortality, ICU Length of stay, respiratory complications after the surgery such as: pulmonary edema, pneumonia and etc. and bleeding after the surgery) and one-year (including left ventricle ejection fraction (LVEF), right ventricle (RV) ejection fraction, severity of tricuspid regurgitation and aortic regurgitation after surgery) outcomes. All data were taken from medical records at Shahid Rajaei Hear Center. Data were analyzed using SPSS 22. Results 94 patients with the mean age of 26.7 ± 9.6 years were enrolled. Most of them were male (59.6%) (P-value: 0.009). In-hospital mortality in our study were 5.3%. Tricuspid regurgitation (TR) was significantly resolved after the surgery (P-value: 0.006). Also, the correction of pulmonary size after the surgery was significant (P-value: 0.000). Conclusion This study showed that the surgery at older age is safe and the results are acceptable. Aging is not a contraindication for TFTC and surgery should be recommended if the patients are diagnosed with TOF at adulthood. Also, screening TOF in adult patients should be considered.
