| Popis: | SummaryBackgroundPrevious studies showed that some parameters, including left atrium diameter and left atrium volume index (LAVI), predicted the success of sinus conversion. However, no previous studies have investigated the association of sinus conversion with LAVI and histopathological findings. This study was designed to investigate the relationship among LAVI, pathological assessment, and failure in sinus conversion after surgery for valvular atrial fibrillation (AF).Methods and resultsA total of 78 patients with left atrium enlargement and valvular AF who underwent maze procedure concomitantly with various cardiac surgeries were classified into one of two groups: those who successfully underwent sinus conversion (Group 1; n=40) and those who did not achieve sinus conversion (Group 2; n=38). Histopathological assessment was performed in 9 cases using tissues derived from the left atrial appendage (LAA). The degree of histopathological change was classified into 1 of 4 grades. LAVI was significantly less in Group 1 than in Group 2 (81±22ml/m2 vs. 122±49ml/m2, p |
