..We tested the effectiveness and safety of a conventional, fully endocardial electrogram-guided circumferential antrum isolation (PVI) with a novel mapping device...

..Whether there is additional long-term benefit from PVS stenting is uncertain. The aim of this study was the evaluation of the long-term success after PV stenting of severe stenosis...

..The purpose of this study was to investigate the efficacy safety of the novel cryoballoon device (Arctic Front, Cryocath, Quebec, Canada)...

..The purpose of this prospective pilot study was to analyse the incidence and possible impact of cryo ablation on cerebral lesions and possible differences to radiofrequency (RF) ablation during pulmonary vein isolation (PVI)...

..We evaluated the success of ablation by using the following measurements: (i) clinical symptoms and duration of symptoms noticed by patients and (ii) synchronous event recording (ER)...

..We applied measurements of the blood concentration of cTnI as a surrogate parameter for the injured cell mass...

..We applied measurements of the blood concentration of cardio-specific biomarkers as surrogates for the injured cell mass...

..The goal of this study was to analyze impact of metabolic syndrome (MetS) and impaired renal function on long-term follow-up after catheter ablation of atrial fibrillation (AF)...

..We assessed primarily the usefulness and predictive accuracy (PA) of AF (atrial fibrillation) burden (AFB) within the first 3 months after the procedure as an early predictor for curative success as well as reduction of symptoms...

..The aim of our study was the evaluation of the severity and long-term outcome of primary angioplasty and angioplasty with pulmonary vein stenting for PVS...

..Our purpose was to describe the modifications of the P-wave duration and Ptf after pulmonary vein antrum isolation (PVAI) in patients with paroxysmal AF...

..Therefore, patients with the presence of RBBB before TAVI may be at lower risk for PM implantation using the Edwards Sapiens System...

..The goal of this analysis was to identify cohort of patients with AF and hypertension, who may have benefit from RASB therapy after pulmonary vein isolation (PVI)...

..We studied possible different thermal stability and usability of the proteins released by cardiac cells injured by different energy sources...

..0001). By multivariate Cox regression model, after adjustment of procedure variables, RRPVD1 was the strongest predictor of development of severe PVS. RRPVD1 >/=25% was a strong independent predictor of development of severe PVS...

..The patient was treated with a combination of quinidine and verapamil and since then remained free of arrhythmias...

..3% and overall accuracy of 92.1%. Conclusions Even at elevated heart rates, DSCT can reliably detect coronary artery stenoses and the results correlate well with those for invasive coronary angiography...

..Contrast-enhanced magnetic resonance angiography (MRA) was used to visualize pulmonary veins and was compared with radiographic angiography...

....

..Long-term success requires persistence of bidirectional conduction block (BCB) in the inferior cavotricuspid isthmus (CTI)...

..HRT obtained from 10-min Holter ECG showed a trend toward the association with mortality in univariate analysis but HRT parameters were not predictive of the outcome in multivariate analyses...

..001; Group 1 vs. Group 3, p< .001; Group 2 vs. Group 3, p = 0.46). CONCLUSIONS: Low AFB < 500 h /3 months was associated with better outcome after PVI. Patients with PAF and high AFB should be treated as patients with PersAF...

..We sought to investigate the correlation between trans-oesophageal echocardiography (TEE) and multi-detector computed tomography (MDCT) for annulus diameter assessment before TAVI...

..In conclusion, our results obtained from a modest number of patients indicate that antiplatelet therapy is safe and effective in preventing thrombus formation on the septal occluder surface...

..Patients with PAF experience a significant improvement in QOL after a successful catheter ablation. In contrast, in patients with recurrence of PAF the QOL showed improvement to a lesser extent and patients experienced ongoing symptoms...

..The purpose of our study was to determine the feasibility of ostial pulmonary vein isolation and to compare continuous radiofrequency (RF) with pulsed RF concerning homogeneity and transmurality of produced lesions...

..Cooled or pulsed RF energy delivery created deeper transmural lesions than conventional RF. To create linear lesions at anatomically complex sites (isthmus), microwave energy seemed superior by rapidly creating deep and long lesions...
