BACKGROUND: There has been a trend in recent years towards less invasive therapy for many congenital cardiac malformations. For the past 5 years, we have employed a technique of limited surgical exposure when repairing atrial defects within the oval fossa. METHODS: Over the 5-year period from July 1992 to August 1997, 115 consecutive patients underwent surgical repair of an isolated atrial septal defect in the region of the oval fossa by a single surgeon. The patients had a limited midline skin incision starting at the line of the nipples and extending inferiorly across 2 to 3 intercostal spaces. A partial sternotomy was performed, sparing the manubrium. Standard instruments and cannulation techniques were used for cardiopulmonary bypass and fibrillatory arrest. RESULTS: There were no deaths and no major complications. The median time to extubation after leaving the operating room was 3 hours (30 minutes to 8 days). Mediastinal drains were removed the morning after surgery. The median stay in the intensive care unit was 7 hours (3 hours to 10 days), and patients were discharged from the hospital a median of 4 days postoperatively (2 to 23 days). CONCLUSIONS: This approach using limited exposure can be applied safely without any new instruments and without peripheral incisions or sites of vascular access, while providing a comfortable exposure for the surgeon and achieving a cosmetically superior result for the patient.
