Cardiac implantable electronic devices replacements in patients followed by remote monitoring during COVID-19 lockdown.

Aims: Following coronavirus disease (COVID-19) outbreak, the Italian government adopted strict rules of lockdown and social distancing. The aim of our study was to assess the admission rate for cardiac implantable electronic devices (CIEDs) replacement procedures in Campania, the 3rd-most-populous region of Italy, during COVID-19 lockdown. Methods and results: Data were sourced from 16 referral hospitals in Campania from 10 March to 4 May 2020 (lockdown period) and during the same period in 2019. We retrospectively evaluated consecutive patients hospitalized for CIEDs replacement procedures during the two observational periods. The number and type of CIEDs replacement procedures among patients followed by remote monitoring (RM), the admission rate, and the type of hospital admission between the two observational periods were compared. In total, 270 consecutive patients were hospitalized for CIEDs replacement procedures over the two observation periods. Overall CIEDs replacement procedures showed a reduction rate of 41.2% during COVID-19 lockdown. Patients were equally distributed for sex (P = 0.581), and both age [median 76 years (IQR: 68-83) vs. 79 years (IQR: 68-83); P = 0.497]. Cardiac implantable electronic devices replacement procedures in patients followed by RM significantly increased (IR: +211%; P < 0.001), mainly driven by the remarkable increase rate trend of both PM (IR: +475%; P < 0.001) and implantable cardiac defibrillator replacement procedures (IR: +67%, P = 0.01), during COVID-19 lockdown compared with 2019 timeframe. Conclusions: We showed a significant increase trend rate of replacement procedures among CIEDs patients followed by RM, suggesting the hypothesis of its increased use to closely monitoring and to optimize the hospital admission time during COVID-19 lockdown.

Effects of COVID-19 lockdown on arrhythmias in patients with implantable cardioverter-defibrillators in southern Italy.

Background: The effects of lockdown on non-COVID patients are varied and unexpected. The aim is to evaluate the burden of cardiac arrhythmias during a lockdown period because of COVID-19 pandemics in a population implanted with cardiac defibrillators and followed by remote monitoring. Methods: In this retrospective, multicentre cohort study, we included 574 remotely monitored implantable cardioverter defibrillator (ICD) and cardiac resynchronization therapy-defibrillator (CRT-D) recipients implanted before January 1, 2019, at seven hospitals in the Campania region, comparing the burden of arrhythmias occurred during the lockdown period because of COVID-19 epidemics (from March 9 to May 1, 2020) with the arrhythmias burden of the corresponding period in 2019 (reference period). Data collection was performed through remote monitoring. Results: During the lockdown period, we observed ventricular tachyarrhythmias (ventricular tachycardia or fibrillation) in 25 (4.8%) patients while in seasonal reference period we documented ventricular tachyarrhythmias in 12 (2.3%) patients; the comparison between the periods is statistically significant (P < .04). Atrial arrhythmias were detected in 38 (8.2%) subjects during the lockdown period and in 24 (5.2%) during the reference period (P < .004). Conclusion: In seven hospitals in the Campania region, during the pandemic lockdown period, we observed a higher burden of arrhythmic events in ICD/CRT-D patients through device remote monitoring.

Anxiety and palpitations in patients with cardiac implantable electronic devices (CIEDs) and the added value of remote monitoring (RM) in the COVID-19 pandemic: an Italian single-centre experience

Aims Mood disorders are common in patients with cardiac implantable electronic devices (CIEDs). The COVID-19 pandemic may have further undermined their emotional well being exacerbating physical symptoms such as palpitations. We investigated the occurrence of anxiety and palpitations in CIEDs patients during the pandemic. In those with remote monitoring (RM) available, we evaluated whether these symptoms were associated with arrhythmic events. Methods and results The generalized anxiety disorder (GAD) 7-items questionnaire and the frequency of palpitations were assessed by telephonic interview. Overall 152 CIEDs patients agreed to be interviewed (119 males, age 69 ± 14 years). The RM was available in 54/152 (36%). Thirty-seven (24%) and 43 (28%) patients had anxiety and palpitations, respectively, and 23 (15%) patients had both. Women were more likely to have symptoms than men (50% vs. 20%;P < 0.01 for anxiety and 53% vs. 24%;P < 0.01 for palpitations). Among patients with palpitations the RM was available in 17/43 (40%) and revealed true arrhythmic events in 7/17 (41%) patients: eight non-sustained ventricular tachycardias (NSVT), two supra-ventricular tachycardias (SVT), four sustained ventricular tachycardias (VT). The RM enabled to detect in six patients a device malfunctioning: in two increased impedance in the shock lead, in three increased capture threshold for the LV lead and in one the battery reached the end of life. Conclusions Patients with CIEDs were likely to experience anxiety and palpitations during the COVID-19 outbreak and the RM has been pivotal to ascertain the occurrence of arrhythmic events and device malfunctioning in symptomatic and asymptomatic patients as well.

Home delivery of the communicator for remote monitoring of cardiac implantable devices: a multicentre experience during the COVID-19 lockdown

Aims During the COVID-19 pandemic in-person visits for patients with cardiac implantable electronic devices should be replaced by remote monitoring (RM), in order to prevent viral transmission. A direct home-delivery service of the RM communicator has been implemented at 49 Italian arrhythmia centres. Methods and results According to individual patient preference or the organizational decision of the centre, patients were assigned to the home-delivery group or the standard in-clinic delivery group. In the former case, patients received telephone training on the activation process and use of the communicator. In June 2020, the centres were asked to reply to an ad hoc questionnaire to describe and evaluate their experience in the previous 3 months. RM was activated in 1324 patients: 821 (62%) received the communicator at home and the communicator was activated remotely. Activation required one additional call in 49% of cases, and the median time needed to complete the activation process was 15 min (25th–75th percentile: 10–20). 753 (92%) patients were able to complete the correct activation of the system. At the time when the questionnaire was completed, 743 (90%) communicators were regularly transmitting data. The service was generally deemed useful (96% of respondents) in facilitating the activation of RM during the COVID-19 pandemic and possibly beyond. Conclusions Home delivery of the communicator proved to be a successful approach to system activation, and received positive feedback from clinicians. The increased use of a RM protocol will reduce risks for both providers and patients, while maintaining high-quality care.

Arrhythmogenic syncope leading to cardiac rhythm management procedures during COVID-19 lockdown.

Introduction: Following the coronavirus disease (COVID-19) outbreak, the Italian government adopted strict rules of lockdown and social distancing. The aim of our study was to assess admission rate for syncope leading to cardiac rhythm management (CRM) procedures in Campania, the third-most-populous region of Italy, during COVID-19 lockdown. Methods: Data were sourced from 14 referral hospitals in Campania from 10th March to 4 May 2020 (lockdown period) and during the same period in 2019. Among consecutive patients hospitalized for CRM procedures during the two observational periods, we retrospectively evaluated those admitted for arrhythmogenic syncope. Admission rate and the type of hospital admission between the two observational periods were compared. Results: Among 951 consecutive patients hospitalized for CRM procedures, 204 were admitted for arrhythmogenic syncope leading to CRM procedures. A significant increase in admission was shown in 2020 compared to 2019 (26.4% vs. 18.3%; P = 0.003). Moreover, regarding the type of admission to hospitals, attendance at the emergency department (ED) significantly increased (83.5% vs. 56.1%; P < 0.001); conversely, a significant decrease in urgent unplanned hospitalizations (6.2% vs. 35.5%; P < 0.001) was observed during COVID-19 lockdown. Conclusions: The hospitalization for arrhythmogenic syncope leading to CRM procedures increased during COVID-19 lockdown.
