Results of the early and mid-term postoperative period after correction of total anomalous pulmonary venous connection

Aim. To compare complications and outcomes in the postoperative period with two different methods for correcting total anomalous pulmonary venous connection.Methods. In this pilot, two-centre, simple, blind, prospective randomised study, the patients’ quality of life after correction of total anomalous pulmonary venous connection in infancy was evaluated using the sutureless (n = 20) and conventional repair methods (n = 20) in 40 patients. The overall mortality and complications in the mid-term were evaluated.Results. The average follow-up was 15 (13; 16) months. Mortality was noted only in the conventional repair group, amounting to 5 (25%) patients (p = 0.018). Severe obstruction of the pulmonary veins anastomosis was also noted only in the conventional repair group (n = 8, 40%; p = 0.0013). Infectious endocarditis was observed in one (6.6%) patient in the conventional repair group (p = 0.42). Arrhythmias were present in 4 (26.6%) patients in the conventional repair group (p = 0.02).Conclusion. The rates of obstruction of the pulmonary vein anastomosis, arrhythmias and death depend on the method of total anomalous pulmonary venous connection correction. The sutureless repair reduces the incidence of early and mid-term postoperative complications compared to conventional repair.Received 16 March 2021. Revised 8 June 2021.
