| Description
| - The aim of this study was to evaluate the characteristics of atrial myocardium in pulmonary veins from subjects with and without a history of atrial fibrillation. A total number of 43 human hearts obtained at autopsy were studied (27 men, 16 women, mean age 67 +- 8 years). Sixteen subjects (group 1) had a history of atrial fibrillation (11 men, mean age 66 +- 10 years). The remaining 27 subjects (group 2) were without arrhythmia (16 men, mean age 68 +- 8 years). The presence and morphology of the myocardial extensions were studied microscopically. In conclusion, a significant interindividual variability in the presence, arrangement, and thickness of atrial myocardial sleeves into PVs was revealed. Patients with a history of atrial fibrillation were found to have longer and thicker myocardial extensions into the upper PVs, and this finding may have implications for the catheter ablation technique.

- Cílem této studie bylo zhodnotit charakteristiky síňového myokardu v plicních žilách získaných od subjektů s a bez historie síňové fibrilace. Celkově bylo zkoumáno 43 lidských srdcích získaných při pitvě. Přítomnost a morfologie extenzí myokardu byly studovány mikroskopicky. Z celkového počtu 172 PV byly extenze myokardu odhaleny u 117 (68%) případů. Vlákna myokardu měla kruhovitou strukturu, přičemž nepřerušené extenze byly objeveny u 74 a nespojité u 24 PV. Maximální délka extenzí byla 48 mm a maximální tloušťka 5 mm. Extenze myokardu byly delší a silnější u horních PV subjektů s předchozí historií síňové fibrilace. Závěr: byla odhalena silná interindividuální variabilita v přítomnosti, délce, síle a uspořádání síňových extenzí myokardu do PV. Pacienti s předchozí síňovou fibrilací měli delší a silnější extenze do horních PV, a to může mít význam pro ablační techniku katetrem. (cs)
