BACKGROUND: We have reported "sandwich technique," via a right ventricular incision, to treat a post-infarction ventricular septal defect (VSD). This technique involves the placement of patches on both the left and right sides of the septum, pinching the VSD sealed with surgical adhesive between the two patches. In this study, we analyzed factors influencing 1-year mortality to determine the pitfalls in our procedure.
METHODS: We evaluated 24 consecutive patients with post-infarction VSD who underwent the "sandwich technique" via a right ventricular incision. One-year survival and major residual leak were used as the criteria for the analysis of survival and technical success, respectively. In protocol 1, clinical variables were evaluated as predictors of one-year mortality. In protocol 2, surgical techniques were evaluated as predictors of major residual leak, which was found to be related to one-year mortality in protocol 1.
RESULTS: In protocol 1, the one-year mortality was higher in patients with major residual leak (75 %, 3/4) than in those without (15 %, 3/20) (p = 0.035). In protocol 2, the patients with major residual leak had smaller patches than those without (41.9 ± 3.8 vs. 47.8 ± 4.8 mm, p = 0.031) and a smaller size difference between the patches and the VSD (22.5 ± 6.5 vs. 30.0 ± 5.7 mm, p = 0.028).
CONCLUSION: For the "sandwich technique" via a right ventricular approach to treat post-infarction VSD, the choice of patch size according to VSD size is an important variable for reducing major residual leak.
