Background: In addition to the Evolution RL sheath, tools by Cook Medical (Bloomington, IN, USA), supporting lead extraction (LE), are available. Data on their use are not reported in detail in previous studies. Moreover, data regarding outcome are lacking. The aim was to evaluate the safety and effectiveness of the Evolution sheath (Evolution RL and Evolution Shortie, Cook Medical) by using a stepwise approach with the available extraction tools and the outcome. Methods:A total of 393 leads in 198 consecutive patients were removed with the Evolution RL sheath and ancillary tools using a stepwise approach.Results: The main indication for LE was infection in 125 (63.1%) cases. The mean implant duration was 95.4 ± 59.7 months. According to our stepwise approach, the Evolution Shortie RL sheath was used in all cases and complete LE was achieved in 24 (12.2%) cases. The Evolution RL was used in 174 (87.8%) cases and the SteadySheath Evolution tissue stabilization sheath (Cook Medical) in 87 (44%) because of tenacious fibrosis anchored targeted leads. Compression coil (OneTie, Cook Medical) was used in 141 (71%) cases. Complete procedural success rate, clinical success rate, and lead removal with clinical success rate were 97%, 99%, and 99.5%, respectively. One major complication (0.5%) and 10 (5%) minor complications were encountered. During a mean time follow-up of 12 ± 9 months, 14 (7%) patients died. Predictors of mortality included impaired renal function (HR 5.7; 95% CI 1.9-17.6; P = 0.002), extraction because of infection (hazard ratio [HR] 4.0; 95% confidence interval [CI] 1-18.1; P = 0.045), and diabetes (HR 3.2; 95% CI 1.1-9.8; P = 0.036). Conclusions:Lead extraction using the Evolution RL bidirectional rotational mechanical sheath and ancillary tools in a systematic stepwise approach was effective and safe.

Occlusion of the LAA by the TP is feasible and effective in most patients with atrial fibrillation at high risk for embolic stroke. Angiography before placement probably affects patch adhesion and is contraindicated.

In addition to PVI, stepwise ablation achieving sinus rhythm and nonatrial arrhythmia inducibility has relevantly improved the clinical outcome of the PAF control strategy.

The increased acquisition speed by AFocusII DL facilitated the reconstruction of the geometric chamber, and the generation of an isochronal activation map reduced processing time and fluoroscopy time per patient, together with the radiation exposure and patient radiation dose. A novel algorithm combining both conventional electrophysiology and a three-dimensional electroanatomic approach for rapid diagnosis, accurate mapping and ablation of iatrogenic atrial tachycardias showed high reproducibility and a satisfactory overall success rate.

Algorithms for the automatic management of the pacing output reduced pacing output in comparison with the standard manual management approach, with potential optimization of battery longevity. Moreover, they reduced the need to manually reprogram CRT-Ds, suggesting the possibility to simplify CRT-D management and facilitate remote monitoring.

We report a patient with non-ischemic dilated cardiomyopathy and low left ventricular systolic function (28%) presenting with an electrical storm originated in epicardial scar and ablated by radiofrequency. This case report suggests that a strategy of epicardial catheter ablation is reasonable for the patient presenting with electrical storm related to structural disease with a low left ventricular ejection fraction.
