Background Patients with permanent pacemakers should be followed up regularly and parameters recorded during the follow-up visits might have potential for further diagnostic studies. Material and methods A pilot cross-sectional study on 127 consecutive patients who underwent pacemaker follow-up was performed. Results The study revealed that patients with older ventricular leads (more than 10 years) have higher lead impedance in comparison with patients with newer ventricular leads (less than 10 years) – 512 Ω vs 461 Ω (median values), with no differences in pacing thresholds, percentage of ventricular pacing, presence of ventricular high rate episodes or status of absolute pacemaker dependency. Conclusions This study demonstrates that parameters obtained from a regular pacemaker check-up differ according to variables such as lead age, which opens a new field for studies investigating other variables (e.g. disease biomarkers) in correlation with parameters from the pacemaker check-up.
背景:装有永久性起搏器的患者应定期随访，随访期间记录的参数可能有进一步诊断研究的潜力。材料与方法对127例连续接受起搏器随访的患者进行初步横断面研究。结果研究显示，与新心室导联(小于10年)的患者相比，年长心室导联(超过10年)的患者具有更高的导联阻抗——512 Ω vs 461 Ω(中位数)，在起搏阈值、心室起搏百分比、心室高速率发作的存在或绝对起搏器依赖状态方面没有差异。结论:本研究表明，定期起搏器检查获得的参数根据导联年龄等变量而不同，这为研究与起搏器检查参数相关的其他变量(如疾病生物标志物)开辟了一个新的领域。

Technological progress in medicine allows us to help more patients with more complex diseases. Cardiology is no exception, with phenomenal progress of cardiac implantable electronic devices (CIED) throughout the last few decades. However, with the invention of new, more complicated CIED technologies, it becomes necessary to remove old systems. Removal of leads (especially those with a long dwell time) became a challenge that had to be overcome. Transvenous lead extraction (TLE) technique was developed to fulfil that need. Variable complexity of lead location, anatomical features and patients’ conditions require that every TLE procedure must be prepared individually, with creativity and multiple tools needed in complicated cases.

Atrial fibrillation remains the cardiac arrhythmia of highest relevance, exerting a huge burden on both societies and individuals. Together with constant technological progress, new methods are continually implemented in everyday practice, which translates into better prognosis and outcomes of invasive treatment. A crucial part of the pulmonary vein isolation procedure is proper reconstruction of cardiac structures. One of the methods offering the highest vision quality is a combination of rotational angiography with electro-anatomical mapping. We present a case of a 62-year-old patient referred to our department diagnosed with paroxysmal atrial fibrillation and successfully treated with catheter ablation using visualization consisting of electro-anatomical mapping and rotational angiography.

For the last 20 years scientific guidelines have suggested either lead abandonment or extraction in cardiac implantable electronic device (CIED) patients (class 2b indications). The former strategy, especially in people with longer life expectancy, produces a population of subjects in whom years after device implantation transvenous lead extraction (TLE) becomes a harmful procedure although it appears the only choice in patients with class 1 indications. We describe a female patient with four leads, including two that were abandoned 20 years ago, with pocket infection and lead-related infective endocarditis in whom the sum of the ages of all leads was 100 years (in our opinion the risk associated with removal of old leads is cumulative). The extraction procedure performed in the maximally safe environment was successful. All the leads were removed, and a major complication, cardiac tamponade, was managed surgically by placing sutures over two large perforations in the right atrial appendage (RAA). We discuss the course of the disease and investigate the possible outcomes of TLE if it had been performed 12 years earlier when replacing the device. We also discuss late and very late consequences of lead abandonment on the basis of this case report.

Background The main determinant of the radiofrequency (RF) ablation effect is transmurality of the lesion. Bipolar radiofrequency ablation (BA) creates transmurality in a higher proportion of cases than unipolar ablation (UA), but little is known about optimal RF settings. Material and methods This study aimed to compare UA and BA based on different application time, cathode tip load, anode size and power settings for achieving a transmural lesion in vitro. A Thermocool electrode was used for ablation (cathode) and a 4 mm or 8 mm tip catheter was used as the ground electrode (anode) for BA. The tested settings were tip load (10 g and 20 g), power (30 W or 40 W), and application duration (30, 60, or 90 s). After ablation, we measured scar size and transmurality of the lesion. Results BA created significantly larger and deeper scars compared with UA. Transmurality was achieved respectively in 42% and 2% of cases (p<0.001). Higher tip load resulted in larger scar size, and transmurality was achieved in 37% and 20% of cases (p=0.05). Scar size and transmurality increased with RF duration (5%, 39% and 42% of specimens, respectively (p<0.001). Bigger tip size of the ground electrode was related to higher transmurality (22% vs 61%, p<0.001). No relationship was found between power and transmurality. Optimal parameter settings were 20 g tip load, indifferent electrode with 8 mm tip, and 90 s RF duration (97.6% transmurality). Conclusions BA is more effective than UA in achieving transmural lesions. Optimal settings for BA consist of longer RF duration, higher tip load, and bigger tip size of the indifferent electrode.
