Zusammenfassung:	Background A histopathological assessment of left atrial appendages (LAA) resected during surgical treatment for atrial fibrillation (AF) was made, with the aim of improving the prediction of postoperative AF recurrence. Methods and Results This clinicopathological study involved 57 surgical cases of valvular AF and 34 age- and sex-matched control autopsy cases with a history of sinus rhythm. LAA from the cases with valvular AF showed greater hypertrophy of cardiomyocytes (p
