p = 0.03). Conclusions: Our results suggest that AEMD is associated with an increased risk of recurrence of AF within 1-month. These data may have implications for the identification of patients who are most likely to experience substantial benefit from cardiversion therapy for AF. (Cardiol J 2013; 20, 6: 639-647)

Patients with LV systolic dysfunction displayed a comparatively greater LA-SRM than patients with normal LVEF. Patients with lesser LA-SRM experienced a greater improvement in LVEF after catheter ablation for AF.

In this study, Acrylic acid (AA)/2-acrylamido-2-methlypropane sulfonic acid (AMPS) hydrogels were prepared by free radical polymerization in aqueous solutions of AA, AMPS, and N,N-methylenebisacrylamide (NMBA) as crosslinker. Potassium persulfate (PPS)/potassium bisulfide (PBS) were used as initiator and accelerator pair. The water absorption capacities and dye adsorption properties of the hydrogels were investigated. Adsorption properties of the hydrogels were evaluated by depending on different adsorption conditions such as different initial dye concentration and contact time. The concentrations of the dyes were determined using UV/Vis Spectrophotome-ter at wavelength 530 nm for safranine T (ST) and 622 nm for brilliant cresyl blue (BCB). Adsorption kinetic studies showed that pseudo-first order kinetic model is suitable to explain the adsorption kinetic data of the hydrogels. Langmuir and Freundlich isotherm models were used to describe adsorption data. The result revealed that the adsorption of basic dyes onto hydrogels fit very well both Langmuir and Freundlich isotherms.

Patients with LVH tend to have a significantly greater degree of LA-SRM, when compared with patients without LVH. Moreover, LA-SRM is a predictor for procedural success in patients undergoing AF ablation procedure.

Objective: The aim of this study was to evaluate the effects of hemodialysis (HD) on right ventricular echocardiographic parameters in patients with end-stage renal failure (ESRF). Methods: Forty-three uremic patients who underwent echocardiography before and 30 minutes after dialysis included in this prospective observational study. Right ventricular systolic function was evaluated using tricuspid annular plane systolic excursion (TAPSE) by M-mode echocardiography and tricuspid lateral annular systolic velocity (Sa) by tissue Doppler echocardiography whereas diastolic function was evaluated using tricuspid early (E) and late (A) diastolic flow velocities by conventional and tricuspid lateral annular early (Ea) and late (Aa) diastolic velocities by tissue Doppler echocardiography. Myocardial performance index was taken as an indicator of global functions. Paired t test or Wilcoxon test were used for statistical analysis where appropriate.Results: E decreased significantly (68±13 cm/s and 56±12 cm/s before and after HD, respectively; p<0.0001) but A did not (p=0.797).TAPSE was 1.84±0.34 cm before HD and showed a significant increase to 2.03±0.20 cm after HD (p=0.006). Right ventricular MPI, Sa and Aa did not change significantly by dialysis (p=0.504; p=0.118 and p=0.150 respectively) whereas Ea decreased to 8.8±2.5 cm/s from 11.3±3.4 cm/s (p<0.001). Ea/Aa ratio also decreased significantly to 0.69±0.35 from 0.84±0.44 with HD (p=0.007).
