Implantation of an implantable cardiac monitor (ICM) is a simple and straightforward procedure. However, with a growing demand for such implants, workload significantly increases. In January 2020, we established a completely nurse-led ICM implantation service (N-IMPLANT) with a standard operating procedure. The present study aimed to analyze the safety, efficacy, and patient satisfaction of N-IMPLANT compared to implantation of ICMs by a physician (P-IMPLANT). Consenting patients implanted with an ICM were included in a prospective registry, which collects patient characteristics, procedural and remote monitoring data. All patients were followed-up by phone interview four weeks after ICM implantation and a standardized questionnaire was completed. Of 321 patients implanted with an ICM (median age 67 years; 33% women), 189 (59%) were N-IMPLANT. Significantly more N-IMPLANT were performed in the outpatient clinic compared to P-IMPLANT (94% vs. 10%; p<0.001). For wound closure, N-IMPLANT used wound glue in 65 (34%) and a single subcutaneous stitch in 124 patients (66%). Two N-IMPLANT patients experienced vaso-vagal reaction during implantation, whereas no adverse events occurred during P-IMPLANT (p=0.51). Two-hundred and fifty-two patients (79%) completed the questionnaire. We found no difference between N-IMPLANT and P-IMPLANT regarding pain after implant, analgesic use, wound closure after 2 weeks and presence and size of patient reported hematoma (see Table). Duration of pain was longer after P-IMPLANT. All N-IMPLANT patients indicated to be satisfied with the implant procedure. Three patients were dissatisfied with P-IMPLANT for the following reasons: ongoing pain at implant site; discomfort at implant site; and too numerous people present during the implant procedure. In three N-IMPLANT (2%) the ICM was explanted prematurely. The reasons for explantation were infection (with reimplantation of another ICM), discomfort at implant site and attempt to avoid interferences during magnetic resonance tomography in one patient each. One P-IMPLANT (1%) was explanted prematurely because of ICM malfunction. Nurse-led implantation of cardiac monitors is effective without compromising patient safety and has excellent patient satisfaction. N-IMPLANT is a suitable model to reduce the workload of physicians.","PeriodicalId":11720,"journal":{"name":"EP Europace","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81854363","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}

The main benefit of the procedure, compared to right ventricular pacing, is encountered in atrioventricular block, where a high burden of ventricular pacing is expected. One of the limits of His bundle pacing is a distal conduction abnormality in the His-Purkinje system. Nevertheless, there is published data that shows the possibility of conduction system capture even in these patients. This retrospective study evaluated the feasibility of permanent His bundle pacing in patients with second or third degree AV block, taking into account the level of block : suprahisian vs. infrahisian.\u0000 \u0000 \u0000 \u0000 45 patients with second or third degree AV block with an attempt at permanent His bundle pacing and an available intraprocedural hisian electrogram for review were included. The procedure went as follows: a lead delivery system including a preformed 3D shaped sheath and a lumenless lead with a fixed exposed helix was placed at the septal atrioventricular junction. Careful mapping was performed until a His bundle signal was recorded. At that site, the pacing response was evaluated at variable pacing outputs. The procedural criteria for success was conduction system capture (selective or non-selective) with an amplitude of less than 2,5V/1ms. If the criteria was met, the lead was fixed, an atrial lead was placed and both connected to a dual-chamber pacemaker. The periprocedural characteristics and those at the three-months follow-up were noted.\u0000 \u0000 \u0000 \u0000 28 patients (62,2%) were diagnosed with suprahisian block, with a procedural success rate of 89 % and 17 (37,8%) with infrahisian block, with a procedural success rate of 59%. QRS duration was 96,4±21,6 ms in those with suprahisian block vs. 119,4±23,8 ms in those with infrahisian block (p=0,0027). There was no significant statistical difference regarding acute His bundle pacing thresholds (1,13±0,63 V/1ms vs. 1,25±0,76 V/1ms, p= 0,66), ventricular sensing (3,46±1,5 mV vs. 3,21±1,6 mV, p= 0,68) and fluoroscopy time (12,75±8,3 min vs. 10,78±9,5 min, p= 0,57) between suprahisian and infrahisian block. Also, the paced QRS duration was similar between the two groups (86,9±13,4 ms vs. 82±14,7 ms, p= 0,38) and narrower than the baseline complex. The three-months follow-up showed stable pacing and sensing parameters, without other procedural or lead related complications.\u0000 \u0000 \u0000 \u0000 In atrioventricular block, permanent His bundle pacing achieves atrioventricular resynchronization, while maintaining rapid and synchronous biventricular depolarization. As expected, in suprahisian blocks the success rate is superior to infrahisian blocks.

PT may still become hazardous in the era of uninterrupted anticoagulation and may require urgent surgical repair. Steam pop is the major cause of PT during PVI with RF ablation and is usually preceded by steep impedance rise measured between tissue and tip of the RF catheter. The STOCKERT SMARTABLATE RF Generator as a core part of technology for CLOSE protocol guided PVI offers the opportunity to automatically stop RF energy delivery within 0.5 seconds if catheter impedance rises above a predefined value: impedance spike cut off (ISCO). The standard – manufacturer recommended – value for ISCO is 50 Ohms per 0.5 seconds.\u0000 \u0000 \u0000 \u0000 To investigate the effect of reduced ISCO during CLOSE protocol guided catheter ablation of AF on the occurrence of acute PT and pericardial effusion (PE) in a large single center series.\u0000 \u0000 \u0000 \u0000 We performed CLOSE protocol guided PVI procedures using Biosense Webster CARTO PRIME 3D navigation system, Smarttouch SF ablation catheter, VIZIGO steerable sheath, invasive blood pressure measurement via radial artery. We changed the STOCKERT SMARTABLATE generator settings to ISCO of 25 Ohms per 0.5 seconds. Cut off during ablation by ISCO led the operator to reduce contact force, angulation/orientation of catheter/steerable sheath, changing to jet ventilation if mechanical ventilation was present. A retrospective analysis of all procedures was performed. Investigation for PT by echocardiography was performed for every drop < 90mmHg systolic blood pressure, immediately after and one day post ablation. Statistical analysis was performed on the evaluable population.\u0000 \u0000 \u0000 \u0000 During 31 months of observation we performed 627 CLOSE protocol guided procedures: 409 PVI only, 218 PVI with additional ablations (cavotricuspid isthmus, slow pathway, additional LA lines, ethanol ablation of vein of marshall).

In the multicentre VISITAX trial, the rate of PT was reported with 3 events per 329 patients (0.9%). By reducing ISCO to 25 Ohms per 0.5 seconds, we could half the rate of PT found in the VISITAX trial. The generator cut off at ISCO of 25 Ohms per 0.5 seconds indicates a potentially dangerous position for ablation.

This debate was put to rest by the Simple and the Nordic ICD trials, and the practice of testing during new implantations has practically been nearly abandoned.\u0000 Nevertheless, induction of VF for testing purposes (VFT) may still have an important role in selective populations at risk for defibrillation failure, who were not included in the SIMPLE and Nordic trials. One such population includes those who undergo device replacements. Old registries demonstrated an increased incidence of significant findings in VFT during replacements. In the present study, we sought to test this observation.\u0000 \u0000 \u0000 \u0000 Evaluate frequency of significant findings and the safety of VFT in subjects undergoing device replacement.\u0000 \u0000 \u0000 \u0000 A prospective observational multi-center study of VFT included consecutive patients undergoing ICD generator replacement in 5 centers in Israel, Europe, and the US. All centers followed the same VFT protocol. The primary outcome was defined as failure to terminate induced VF with a single shock at 10 Joules below the maximal capacity of the device. Secondary outcomes included complications of VFT. Patients were followed-up at 1 month and 6 months post-procedure. Data collection included documentation of any peri-operative complications and clinical endpoints (occurrence of appropriate shock, inappropriate shocks, lead failure, need for re-intervention, and infection).\u0000 \u0000 \u0000 \u0000 A total of 92 patients were eligible, and consented for the study, of which 84 underwent DFT during battery replacement. The median age was 68 years and 79.8% were male subjects. Induction of VF was successful in all 84 patients as well as VFT with a successful conversion on first attempt. During follow up one patient had two appropriate ICD shock events. In four patients, the ICD programming was changed. None suffered an inappropriate shock. There was no evidence of lead malfunction. A total of two deaths occurred, none of which were related to the device.\u0000 \u0000 \u0000 \u0000 The present study found VFT was not associated with complications in patients undergoing ICD/CRTD generator replacement but produced no clinically important information.\u0000","PeriodicalId":11720,"journal":{"name":"EP Europace","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82986704","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}

Procedure time was 116 min. PFA catheter LA dwell time was 29 min. Fluoroscopy time was 26 min. (All values are median). In 1 patient with roof dependent flutter, a roof line was intentionally created. In 2 patients, unintentional bidirectional mitral isthmus block was created. There was no phrenic nerve or esophageal damage. In 1 patient, pericardial drainage after cardiac tamponade was performed. In-hospital stay, and 30-day follow-up were uneventful.
