RESUMO
Background: We aim to determine the surgical outcomes of adult patients with total anomalous pulmonary venous connection (TAPVC) and examine the regression of pulmonary artery (PA) pressures after the procedure. Methods: We reviewed the hospital records from 2003 to 2022 and identified 49 adult patients with TAPVC. We assessed their surgical outcomes and the trend of PA pressures after the procedure. Continuous data are presented as mean ± SD or median (interquartile range) and categorical variables are presented as percentages. Results: The median age of the patients was 23 years (range 18-42) and 31 (63.3%) were male. Thirty-six patients (73.5%) had supracardiac TAPVC. The mean systolic PA pressure was 65.8 ± 16.4â mm Hg and it decreased by 47.9% (34%, 61.8%) after surgery. Moderate or more tricuspid regurgitation was seen in 27 (55.1%) patients before surgery; however, it was present in only 3 (6.1%) patients during early follow-up. There was no intraoperative or 30-day mortality, and the median hospital length of stay was six days. Long-term follow-up data were available for 29 patients with the average duration of follow-up being 5.6 years (range 6 months to 15 years) and the mean systolic PA pressures of this cohort was 29.8±7.9 mm Hg. Forty-six (93.1%) patients were asymptomatic; four women had uneventful pregnancies and delivered healthy children. Conclusion: Surgical repair of the naturally selected group of adult TAPVC patients can be performed safely with good results. Regression in flow-related pulmonary hypertension and an improvement in functional quality of life are seen in nearly all patients.
