Outcome after surgical repair of partial anomalous pulmonary venous connection

OBJECTIVE To review the operative results of 55 cases of partial anomalous pulmonary venous connection (PAPVC). METHODS This retrospective case series of 55 cases of PAPVC operated from January 2011 to June 2016 at CPE Institute of cardiology, Multan. Baseline characteristics of patients, their operative findings and results were retrieved from the hospital record. RESULTS Operation for PAPVC was performed in 55 patients. Patient's age varied from 3-28 years (mean 12.56±7.49), their weight was 9-62 kg mean (25.61±16.28). There were 41(74.5%) males and 14(25.5%) females. 49(89.0%) patients had right sided PAPVC associated with ASD moreover 3(5.4%) cases had right pulmonary vein draining into right atrium. While there was only one case having left sided PAPVC (1.8%) and two cases (3.6%) of bilateral PAPVC (4%). Reassuringly, there was not a single mortality. However, one patient developed junctional rhythum, which was successfully controlled on amiodarone. SVC obstruction having 6mmHg gradient was observed in one case however patient is doing well and is on follow up since 9 months. CONCLUSION Surgical correction of PAPVC generally carries highly reproducible results with low morbidity.
