Objectives: There is no consensus about optimal surgical technique for the repair of scimitar vein, an anomalous right pulmonary venous connection to the inferior vena cava. Our current experience with a direct anastomosis of the scimitar vein to the left atrium via sternotomy may be shared with other centres, but has not been widely published.
Methods: Six consecutive patients (age 6 months to 17 years, mean 5 years) operated on in 2009-12 were retrospectively reviewed. Through median sternotomy and with cardiopulmonary bypass, the mobilized anomalous right pulmonary vein was brought through a large pericardial opening posterior to the right phrenic nerve and anastomosed onto the right side of the posterior left atrium with access via an existing or a surgically created atrial septal defect.
Results: Five patients had primary venous repair and one had a previous failed repair using an intra-atrial baffle. The median cardiopulmonary bypass and cross-clamp times were 88 and 38 min, respectively. The median ventilator time was 1 day and the median stay at the intensive care unit 3.5 days. There were no deaths within a median follow-up of 28 months (range 8-41 months), nor reoperations or instances of pulmonary venous obstruction.
Conclusions: Anatomic repair of the scimitar vein based on reimplantation onto the left atrium via sternotomy is conceptually appealing. The surgery results in a safe and reliable repair in patients with a wide age spectrum. Durability needs on-going assessment in longer-term follow-up.
