Key result
Surgical repair of partial anomalous pulmonary venous connection using either single or double patch intra-atrial baffle techniques was safe, resulting in zero early or late mortality and a low incidence of post-operative complications across all age groups.
Why the study?
Surgery for PAPVC has a good prognosis when done early, but patients have increased morbidity at older ages, and factors related to outcomes by age and surgical technique are unclear.
Does the surgical repair of PAPVC using single or double patch techniques lead to safe and reproducible clinical outcomes across different age groups?
Cohort (n=50)

Surgical repair of partial anomalous pulmonary venous connection using intra-atrial baffle with single or double patch techniques provides excellent outcomes with zero mortality and acceptable low rates of transient sinus node dysfunction and venous obstruction across various age groups.
Background: Partial anomalous pulmonary venous connection (PAPVC) is characterised by failure of one or more pulmonary veins to connect with the left atrium. Surgery for PAPVC has a good prognosis when done at an early age, whereas patients have increased morbidity. We reviewed our experience with the single and double patch technique in different age groups of patients with PAPVC at our institution. Aims and Objectives: The current study aims primarily to find out factors related to the outcome of patients with different age groups undergoing surgery for PAPVC using the single patch and double patch technique. Materials and Methods: Between January 2021 and December 2025, we operated 50 cases of PAPVC. All the patients were discharged and are now in our follow-up. We analysed all relevant data with computer software. Clinical and echocardiographic follow-up was made. Results: PAPVC was partial, right-sided and associated with ASD in all cases. We found PAPVC to the superior vena cava (SVC) and cavoatrial junction in 23 (46%) cases and PAVPC to the right atrium in 27 (54%) cases. Surgical correction was done in all patients. About 23 (46%) patients were operated with the two patch technique, and 27 (54%) patients were operated with the single patch technique. Mean cardiopulmonary bypass time 86.84±13.139 min, mean age was 15.76±16.824 years. There were no early or late mortality. One (2%) patient had increased flow velocity across the SVC, and 3 (6%) patients had increased flow velocity across the pulmonary vein patch. One patient was reoperated due to patch dehiscence. Early temporary sinus node dysfunction was found in 8 (16%) cases requiring no early or late permanent pacemaker implantation. Conclusion: PAPVC surgery using the double patch technique is safe and easily reproducible in different age groups of patients.

Saha et al. (2026) conducted a cohort in Partial anomalous pulmonary venous connection (PAPVC) (n=50). Double patch technique vs. Single patch technique was evaluated on Early or late mortality. Surgical repair of partial anomalous pulmonary venous connection using either single or double patch intra-atrial baffle techniques was safe, resulting in zero early or late mortality and a low incidence of post-operative complications across all age groups.
