However, recent studies suggest that left bundle branch area pacing (LBBAP) may provide even better outcomes as a CRT. In this case, we observed a dynamic alteration in the left ventricular (LV) activation pattern when transitioning from RVA-PICM to LBBAP, including changes in the functional block line.Case: A female patient with dilated-phase hypertrophic cardiomyopathy (d-HCM), septal, and apical myocardial damage caused by cardiomyopathy, and prior ventricular tachycardia ablations experienced worsening heart failure due to dyssynchronous LV activation from RVA pacing (paced QRS duration of 250 ms). She underwent an upgrade to LBBAP (paced QRS duration of 160 ms) as CRT. Six months later, three-dimensional LV activation mapping was performed during both RVA pacing and LBBAP. During RVA pacing, a functional conduction block was observed in the anterior wall, resulting in unidirectional excitation propagation in a counterclockwise direction from the septum and a significant delay in the basal-mid anterior wall. In contrast, with LBBAP, the functional conduction block shifted to the septal-apical region, enabling bidirectional excitation propagation to the basal-mid lateral wall and facilitating synchronized excitation in vertically opposing LV segments.Conclusion: The change in LV activation is specific to this d-HCM case with damaged septum and apex; however, it provides one of the insights into the mechanisms by which LBBAP exerts its beneficial effects when upgrading from RVA-PICM.","PeriodicalId":54653,"journal":{"name":"Pace-Pacing and Clinical Electrophysiology","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144057942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A carotid shuttle sheath with the tip fashioned into a bevel shape was used as a makeshift dilator to dissect and free the leads from adhesions. A bioptome, introduced through the TightRail sheath, was employed to dislodge the right ventricular (RV) lead tip, while a snare introduced subsequently through the same access was used to grip the distal end of the RV lead. The lead was extracted using the snare without the need for additional femoral or jugular access.Conclusion: To the best of our knowledge, the use of this bioptome and snare technique, through the TightRail sheath, without employing femoral or jugular access for lead extraction, has not been previously reported. This case highlights the importance of innovative techniques in successfully addressing challenging TLE cases.","PeriodicalId":54653,"journal":{"name":"Pace-Pacing and Clinical Electrophysiology","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143992431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the study was to determine the impact of the elimination of antral low-voltage, fragmented electrograms (LFEGMs) identified by high-density (HD) mapping on the rate of pulmonary vein isolation (PVI) durability.Methods: Sixty patients with paroxysmal atrial fibrillation (PAF) were randomly assigned to a verification of PV entrance block and presence of LFEGMs on antral isolation lines with an HD mapping catheter (HD group) or to a verification of PV entrance block with a circumferential mapping catheter alone (CM group).

LAA occlusion device infection is a challenging complication, and there is a paucity of data on the management and outcomes of LAA occlusion device infection. We aimed to summarize the existing literature and highlight the knowledge gap in this area.Methods: A detailed search was conducted through the databases PubMed/MEDLINE, EMBASE, Web of Science, CINAHL, and Cochrane Central using the relevant keywords. All cases with presented data regarding diagnosis, treatment, and outcome were included from the reports.Results: The analysis included 12 case reports encompassing a total of 12 patients. The mean age was 73.6 ± 11.0 years, and 50% of the cases were male. The most commonly implanted device was the Watchman (in eight of the 12 cases). The median time between LAA closure and infection was 6.6 (0.2-36) months. Transesophageal echocardiography was diagnostic in all cases, and positron emission tomography/computed tomography (PET/CT) was useful in diagnosis in three cases. The most common pathogen was Staphylococcus aureus (n = 7). The LAAC device was removed in seven cases; one patient refused surgery, and in the other three cases, removal of the device was not considered appropriate due to the patient's poor condition. Data on whether the device was removed could not be retrieved for one patient. Mortality occurred in three cases (25%), and all deaths occurred during hospitalization.Conclusion: LAA closure device infections are rare but carry a high risk of complications and mortality. Treatment should include device removal in appropriate cases, and antibiotherapy alone should be considered only in selected cases.
