Preferential conduction patterns along the coronary sinus during atrial fibrillation in humans and their modification by pulmonary vein isolation

IntroductionCorrelation function analysis applied to endocardial electrograms has earlier been used for analysis of agreement between signals and direction of activation during atrial fibrillation (AF). This study was aimed at evaluating whether preferential activation patterns along the coronary sinus (CS) exist in patients with AF.MethodsTwenty-seven patients (57 ± 10 years old) admitted for electrophysiological (EP) study (10 patients) and/or AF ablation (17 patients) were studied, 8 with permanent and 19 with persistent AF. Unipolar signals were recorded during 60 seconds from a 10-pole CS catheter during AF at baseline (BL) and after isolation of left and right pulmonary veins and after additional lines in the left atrium (LA) (End). Correlation function analysis was applied to signals from each pair of adjacent electrodes, and graphs of cumulated time delay were made to enable interpretation of direction of activation.ResultsCorrelation between paired signals was highest in the distal and middle parts of CS and lowest in the proximal CS. In 21 patients, correlation values greater than 0.8 between closely spaced electrodes suggested uniform propagation of the fibrillatory waves. In 18 of 21 patients, preferential conduction pattern along CS was seen. Of those, 15 patients had left-to-right conduction, and 3 had right-to-left conduction. During ablation, atrial fibrillation cycle length increased from 184 ± 32 milliseconds at BL to 193 ± 39 milliseconds after pulmonary vein isolation and 215 ± 39 milliseconds at the end of ablation (P = .03, BL vs End). Because of ablation, preferential conduction along CS changed in 4 patients from left to right at BL to simultaneous CS activation or right to left. In 1 of 3 patients with simultaneous activation at BL, the direction changed to right to left. No direction change was observed in any of the 3 patients with right-to-left activation at BL.ConclusionsAtrial activation during AF exhibits a high degree of organization in distal and middle CS. Preferential conduction patterns observed in most patients may indicate either relatively dominant stable reentry circuits in the LA or activation spread from a focal source. The changes in preferential conduction during ablation of AF may reflect modification of AF substrate and indicate persistent right atrial sources not affected by ablation in the LA only.Pyotr G.

Gender and age differences in symptoms and health-related quality of life in patients with atrial fibrillation referred for catheter ablation

Background: Primary indication for catheter ablation of atrial fibrillation (AF) is to reduce symptoms and improve health-related quality of life (HRQoL). There are data showing differences between the genders and between younger and older patients. To evaluate this, we studied a large Scandinavian cohort of patients referred for catheter ablation of AF. Methods: Consecutive patients filled out the ASTA questionnaire, assessing symptoms, HRQoL, and perception of arrhythmia, prior to ablation. Patients were recruited from four Swedish and one Danish tertiary center. Results: A total of 2493 patients (72% men) filled out the ASTA questionnaire. Women experienced eight of the nine ASTA scale symptoms more often than men. Patients <65 years reported four symptoms more often, only tiredness was more frequent in those ≥65 years (P =.007). Women and patients <65 years experienced more often palpitations and regarding close to fainting and this was more common among women, no age differences were seen. Women and men scored differently in 10 of the 13 HRQoL items. Only negative impact on sexual life was more common in men (P <.001). Older patients reported more negative influence in four of the HRQoL items and the younger in one; ability to concentrate. Conclusions: Women experienced a more pronounced symptom burden and were more negatively affected in all HRQoL concerns, except for the negative impact on sexual life, where men reported more influence of AF. Differences between age groups were less pronounced. Disease-specific patient-reported outcomes measures (PROMs) add important information where gender differences should be considered in the care
