Bacgrounnd: The main reason for the adoption of the caval division technique is primarily to avoid sinus node dysfunction post-operatively. Equally, this technique also has the advantage of reduced complication of venous obstruction either across the superior vena cava right atrial (SVC-RA) appendage junction and/or pulmonary veins area.
Objectives: To assess the impact of Caval Division Technique on venous drainage after surgery.
Methods: The medical records for 38 consecutive patients who had a sinus venous atrial septal defect repair using the caval division technique from September 2009 to October 2011 were retrospectively reviewed and grouped into two: A total of 33 patients with normal intraoperative pressure across the anastomotic and venous areas (Group 1) and 5 patients with increased intraoperative venous pressure gradient across these areas (Group 2) with 1 patient in Group 2 having immediate surgical intervention.
Results: The pressure across the cavoatrial anastomotic sites in 2 patients was 8 mmHg, in 2 patients was 6 mmHg and in 1 patient was 11 mmHg as indicated by the intraoperative pressure monitoring line and/or transesophageal echocardiograpy. However, the echocardiography performed at follow up showed no gradient across the SVC-RA appendage anastomotic site and there was no mortality recorded.
Conclusion: In conclusion, the early operative impact of the caval division technique on venous drainage is of a good outcome and even when detected by intraoperative pressure line monitoring or transesophageal echocardiography, it can resolved spontaneous or attended to by additional band resections, especially in young children.
