AbstractPermanent pacemaker implantation in low birthweight (LBW) babies with congenital complete heart block is extremely challenging due to a paucity of appropriate pulse generator placement pocket sites. The development of infection following an implantation procedure can pose a life-threatening risk to the patients. With more patients in the younger group receiving these devices than ever before and the rate of infection increasing rapidly, a closer look at the burden of infection and its impact on outcome of these patients is warranted. We report mucormycosis infection at the abdominal pacemaker pocket site of an infant requiring pacemaker explantation and re-insertion into the intrapleural space.

Background: Permanent pacemaker (PPM) implantation is the main complication of transcatheter aortic valve replacement (TAVR). Few studies have evaluated the requirement for PPM implantation due to ECG changes following TAVR in a Chinese population.Objective: Our study aimed to evaluate the incidence and predictors of PPM implantation in a cohort of Chinese patients with TAVR.Methods: We retrospectively evaluated 39 consecutive patients with severe native aortic stenosis referred for TAVR with a self-expandable prosthesis, the Venus A valve (Venus MedTech Inc., Hangzhou, China), from 2019 to 2021 at the Heart Center of Affiliated Zhongshan Hospital of Dalian University. Predictors of PPM implantation were identified using logistic regression.Results: In our study, the incidence of PPM implantation was 20.5%. PPM implantation occurs with higher risk in patients with negative creatinine clearance (CrCl), dyslipidemia, high Society of Thoracic Surgeons (STS) Morbimortality scores, and lead I T wave elevation. TAVR induced several cardiac electrical changes such as increased R wave and T wave changes in lead V5. The main independent predictors of PPM implantation were new-onset left bundle branch block (LBBB) (coef: 3.211, 95% CI: 0.899–7.467, p = 0.004) and lead I T wave elevation (coef: 11.081, 95% CI: 1.632–28.083, p = 0.016).Conclusion: New-onset LBBB and lead I T wave elevation were the main independent predictors of PPM implantation in patients undergoing TAVR. Clinical indications such as negative CrCl, dyslipidemia, high STS Morbimortality scores, and an increased T wave elevation before TAVR should be treated with caution to decrease the need for subsequent PPM implantation.

Background: Since the emergence of the SARS COV-19 pandemic, multiple extrapulmonary manifestations of the virus have been reported from around the world. Cardiovascular complications including arrhythmias in patients with COVID-19 have been described in multiple studies. Our aim was to review various case reports detailing the new onset of heart block in COVID-19 patients and to summarise the clinical course of these patients. Methods: We systematically reviewed all reports published and indexed in PubMed, Scopus, and Embase between March 2020 to May 2021, analyzing the relation between the demographics of the patients, pre-existing comorbidities, and the progression of heart block in patients infected with COVID-19. Results: We identified and included in this study 30 relevant articles describing 49 COVID-19 patients with heart block. Among them, 69.3% (n=34) of patients suffered from at least one comorbidity. 36.73% (n=18) of the patients showed spontaneous resolution of the heart block. Conversely, 63.26% (n=31) of the patients had persistent heart block, out of which 16.33% (n=8) and 42.86% (n=21) were implanted with a temporary and permanent pacemaker respectively. The reported mortality rate was 22.45% (n=11) during hospitalization. We noted that 45.45% (n=5) of the patients who died had complete heart block. 24.49% (n=12) of the patients in the studies we reviewed were suspected of having myocarditis. However, none were confirmed with MRI or cardiac biopsy. Conclusions: Additional research is necessary to unearth the mechanism of development of heart block in COVID-19 patients as well as its implications on the clinical course and prognosis. Physicians must be aware of the importance of monitoring patients hospitalized for COVID-19 for arrhythmias including heart blocks, especially in the presence of comorbidities. Early detection can improve the prognosis of the patient.

Background and Objective: The implantation of a permanent cardiac pacemaker for the treatment of bradyarrhythmia is one of the most popular cardiac interventions. The goal of this study is to look at the clinical profiles of individuals who have permanent pacemakers implanted Material and Methods: The study was conducted using observational methods. The study included patients who received a permanent pacemaker for bradyarrhythmias between November 2019 and November 2021. A thorough review of the demographic profile and indications was performed. Results: The vast majority of the 312 patients were older, with the majority being between the ages of 56 and 88 years old (75 % ). Pacemakers were implanted in more men than in women. Complete heart block was the most common ECG finding and the most common presenting symptom was syncope. The most prevalent sign of pacing was acquired A-V block, and the most common pacemaker mode was single chamber (VVI/VVIR). Conclusion: Acquired A-V block and SSS were found to be the most common reasons for pacemaker implantation in our study. Higher implantation rates were linked to advanced age and male gender.
