    Abstract:
    BACKGROUND: Ventricular septal rupture (VSR) is an infrequent but life-threatening situation. Although outcomes have improved with the introduction of infarction exclusion, we have experienced difficulty in determining the optimal patch size and shape for obtaining good outcomes. Therefore, we modified the infarction exclusion technique. Herein, we review our experience on the basis of early closure of VSR with and without use of the infarction exclusion technique. METHODS: We retrospectively analyzed the hospital records of 33 patients who underwent surgical treatment for VSR. We employed Dagget's method from 1982 to 1995, and then introduced the infarction exclusion technique in 1995. We have developed two modifications: the two-sheet single-patch technique and the three-sheet double-patch technique. RESULTS: Overall hospital mortality was 41.9% and that of the infarction exclusion group was significantly lower than the hospital mortality rate of the noninfarction exclusion group (21% and 63%, respectively, p = 0.0266). Late mortality of survivors was low in all groups during the observation period. The three-sheet double-patch group showed no residual shunt. This difference in outcomes between the single-patch and double-patch groups was statistically significant (p = 0.0174). CONCLUSIONS: The two-sheet method facilitates the restoration of ventricular geometry. A double-patch using the three-sheet method may be useful for reducing residual shunt.
