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.","PeriodicalId":247417,"journal":{"name":"Heart Beat Journal","volume":"22 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134360709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":247417,"journal":{"name":"Heart Beat Journal","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128325853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
