The influence of cardiac geometry on the results of XXXX repair.

@entity1 @entity551 @entity439 @entity86
Operative repair of @entity439 should improve left ventricular function. Despite its theoretic advantage, the mortality following this operation is high, and many @entity1 have severe @entity551 . The cardiac findings were studied in 18 @entity1 who died after repair of @entity439 . All hearts were examined at autopsy after postmortem coronary arteriography and fixation in a distended state. Five @entity1 in Group I had intractable fatal @entity551 , 7 in Group II initially had severe @entity551 that improved, and 6 in Group III did not have @entity551 . Curvature thickness indexes (CTIs) of the ventricular segments, which correlate with their pressure-producing activity, were determined in the 18 hearts. CTIs for the left ventricular free wall and septum were lower in Group I and Group II @entity1 with @entity551 than those in Group III without. The reduced CTIs in @entity1 with @entity86 appear to arise as a result of ventricular reconstruction that reduces ventricular wall curvature. The authors suggest that left ventricular function after @entity439 resection would be improved by inverting, rather than everting, the edges of the ventriculotomy, thereby increasing wall curvature and the CTI. Noninvasive determinations of the CTI may prove of value in guiding topographic reconstruction of ventricles with @entity439 .
