The feasibility and effectiveness of virtual visits (VVs) for cardiac electrophysiology patients are still unknown. We aimed to assess the feasibility and effectiveness of VVs as compared to in-person visits, and to describe patient experience with virtual care in clinical electrophysiology. We prospectively enrolled patients scheduled to receive a clinical electrophysiology evaluation, dividing them in two groups: a VV group and an in-person visit group. Outcomes of interest were: (1) improvement in symptoms after the index visit, (2) disappearance of remote monitoring (RM) alerts at follow-up, (3) necessity of urgent hospitalization and (4) patient satisfaction measured by the Patient Satisfaction Questionnaire-18 (PSQ-18). This study included 162 patients in the VV group and 185 in the in-office visit group. As compared to in-person visits, VVs resulted in a similar reduction in RM alerts (51.5% vs. 43.2%, p-value 0.527) and in symptomatic patient rates (73.6% vs. 56.9%, p-value 0.073) at follow-up, without differences in urgent hospitalization rates (p-value 0.849). Patient satisfaction with VVs was higher than with in-person evaluation (p-value < 0.012). VVs proved to be as feasible and as effective as in-person visits, with high patient satisfaction. A hybrid model of care including VVs and in-person visits may become the new standard of care after the COVID-19 pandemic is over.

The burden of cardiovascular comorbid conditions was significantly higher in patients with atrial fibrillation (AF); most of them are affected by hypertension, chronic kidney disease (CKD) and/or diabetes mellitus (DM). DM represents a well-known risk factor for the development and maintenance of AF; the coexistence of DM and AF is also associated with an increased risk of mortality and stroke. Moreover, DM is currently the main cause of renal impairment and the leading cause of dialysis in the world. The hyperglycemia is responsible for inducing redox imbalance and both systemic and intrarenal inflammation, playing a critical role in the pathogenesis of diabetic kidney disease. Long-term thromboembolic preventive therapy in AF patients with DM and CKD may be more challenging because both DM and CKD have been independently associated with an increased thromboembolic and bleeding risk, which results from the prothrombotic and proinflammatory status. Vitamin K antagonists (VKAs) are characterized by numerous critical issues such as a narrow therapeutic window, increased tissue calcification and an unfavorable risk/benefit ratio with low stroke prevention effect and augmented risk of major bleeding. On the other hand, Direct Oral Anticoagulants (DOACs) are currently contraindicated in dialysis patients even if mounting evidence suggests that they may have a nephroprotective role in AF patients with DM and CKD. Consequently, the choice of anticoagulant therapy in this setting of patient seems to be very challenging. The aim of this review is to investigate the role of DOACs in diabetic patients and its nephroprotective role by reviewing the current literature.

There is lack of evidence regarding the screening role of ECG for sudden cardiac death (SCD) prevention. Our aim was to evaluate the prevalence of ECG abnormalities among teenagers according to sport participation and competitive status.Eleven thousand nine hundred and forty-nine Italian pupils from 179 secondary schools (13-19 years) were consecutively enrolled. ECG abnormalities were divided into minor and major. Medical history, clinical examination and sport activity information were acquired. Further evaluations were suggested in case of major ECG abnormalities. Follow-up was performed at 2 years.N = 1945 (16%) pupils had ECG abnormalities. Major ECG abnormalities were detected in 13% of the cohort, minor in 34%. ECG abnormalities were more common in nonathletes compared with athletes. A diagnosis of cardiac disease was reached in 25 (1.6%) of the pupils with major ECG abnormalities.ECG abnormalities are common among young populations and more prevalent in nonathletes. Among pupils with major ECG abnormalities 1.6% had a cardiac disease diagnosis. Our results are in line with the data supporting ECG screening in the general young population.

During the coronavirus disease 2019 (COVID-19) worldwide pandemic, patients with cardiac implantable electronic device (CIED) refused scheduled follow-up visits because of the risk of infection. In this scenario, different telemedicine strategies have been implemented to ensure continuity of care to CIED patients. Patients can be monitored through dedicated applications, telephone calls, or virtual visits providing easy access to valuable information, such as arrhythmic events, acute decompensation manifestations, and device-related issues, without the need for in-person visits. This review provides a comprehensive description of the many possible applications of telemedicine for CIED patients during the COVID-19 period.

Abstract Aims During the Coronavirus Disease 2019 (COVID-19) pandemic in-person visits were reduced to prevent potential risk of exposure. Virtual visits (VVs) represent an innovative model to take care of patients with cardiac implantable electronic devices (CIEDs). The aim of this study is to evaluate the safety and feasibility of VV in the management of CIED patients. Methods and results We performed a prospective study including all CIED patients who received a VV from July 2020 to July 2021. Blood pressure, arterial oxygen saturation, heart rate, and body weight were registered by the patient. Moreover, we sent to the patient a questionnaire to evaluate the patients’ satisfaction about VV. We enrolled 182 patients in the study period. The mean age of patients was 70.2 ± 13.5 years-old and the majority (61.1%) was male. In two cases, VVs were not performed due to technical issues. Overall, 70.9% of patients utilized a smartphone, while 20.1% and 9% used, respectively, a tablet or a personal computer. The mean duration of VV was 27.8 ± 7.8 min. Patients helped by a caregiver were 64 (35.2%). One urgent/emergent in‐person visit was performed in a patient with acute heart failure. Overall, VV was preferred to in-person evaluation. Conclusion VV is a safe and feasible approach to follow-up CIED patients. A high degree of patient satisfaction was reached after VV. The use of VV has promising potential and should be implemented beyond COVID-19 period and integrated in the healthcare system as a new model of care.

Abstract Aims The outbreak of the Coronavirus Disease 2019 (COVID-19) pandemic forced a reorganization of the healthcare system. In order to prevent potential risk of exposure, virtual visit (VV) has been implemented in the treatment and follow-up of COVID-19 patients with cardiovascular diseases. The aim of this study is to evaluate the feasibility and efficacy of VV in the management of post COVID-19 cardiovascular patients. Methods and results We enrolled all patients with cardiovascular comorbidities tested negative for Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) and discharged from our Cardiology Department from January 2021 to June 2021. We scheduled a VV after 30 days from discharge to check the clinical status of the patients, optimize therapy, and establish a Follow-up protocol. Blood pressure, arterial oxygen saturation, heart rate and body weight were registered. To evaluate the patients’ satisfaction of VV, a questionnaire was administered. We performed 25 VVs in the study period; the mean age of patients was 67.5 ± 15.6 and male were 15 (65.2%). The mean duration of VV was 25.9 ± 4.6 min. The caregiver had an active role in nine (36%) cases. No urgent/emergent in-person examinations were performed. A high degree of patient satisfaction was reached and VV was preferred to in-person evaluation. Conclusions VV visit was useful to Follow-up post COVID-19 cardiovascular patients. A high degree of patient satisfaction was reached without jeopardizing quality of care.

BACKGROUND: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 centers.METHODS:According to individual patient preference or the organizational decision of the center, 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 centers were asked to reply to an ad hoc questionnaire to describe and evaluate their experience in the previous 3 months.RESULTS: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.

Introduction: Remote monitoring (RM) has profoundly transformed the standard of care for patients with cardiac electronic implantable devices. It provides easy access to valuable information about arrhythmic events, acute decompensation manifestations and device-related issues without the need of continuous in-person visits. Methods: Starting March 1st, 332 patients were introduced to a RM program during the Italian lockdown in order to limit the risk of in-hospital exposure to Severe Acute Respiratory Syndrome Coronavirus-2. Patients were categorized in two groups based on the modality of RM delivery [home (n=229) vs office (n= 103) delivered]. The study aimed at assessing the efficacy of the new follow-up protocol, reported as the mean RM Activation Time (AT) and the need for technical support for its activation. Patients' acceptance and anxiety status was also quantified by means of the Home Monitoring Acceptance and Satisfaction Questionnaire and the Generalized Anxiety Disorder 7-item scale. Results: AT time was <48 hours in 93% of patients and 7% of them required further technical support. Despite a higher number of trans-telephonic technical support in home-delivered RM group, AT was comparable between groups (1.33±0.83 days in home-delivered vs 1.28±0.81 days in office-delivered patients; p=0.60). Twenty-eight (2.5%) urgent/emergent in-person examinations were planned. High degree of patient's satisfaction was reached in both groups while anxiety status was higher in office-delivered group. Conclusions: RM was effective, safe and well tolerated by patients during the Italian lockdown. Our findings confirm the efficacy of this approach to reduce in-hospital visits, guaranteeing patients' safety and quality of care.

*These authors contributed equally to this work Abstract: Currently, atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, with a prevalence of about 2–3% in the general population, representing a powerful risk factor for stroke and systemic thromboembolism and increased mortality and morbidity. Restoration of sinus rhythm is an important treatment option in AF and has a high success rate, but there is the need for an effective anticoagulation strategy to reduce the risk of embolic events. Anticoagulation with vitamin K antagonists is often associated with failure to achieving effective international normalized ratio. In this setting, recent data have led to extended approval for rivaroxaban in clinical practice, because it is effective and safe in patients with AF undergoing cardioversion, avoiding additional health costs and related time loss, while improving patient satisfaction. The present report provides an overview of the main randomized controlled trial and the main real-life studies, documenting the use of rivaroxaban in patients with non-valvular AF who underwent the cardioversion procedure. Considering that novel non-vitamin K antagonist oral anticoagulants in left atrial appendage thrombi resolution is still unknown in the real-world practice, the main findings on the use of rivaroxaban in this setting are also discussed.

Congenitally corrected transposition of great arteries (ccTGA) is a discordant connection between atria, ventricles and main arteries, with normal systemic circulation: right atrium links via mitral valve to the morphologic left ventricle, connected to the pulmonary artery. Left atrium links to the right morphologic ventricle, from which aorta origins. Case report: a 42 years old men with ccTGA come under our investigation for exercise-induced dyspnoea. He was assuming carvedilol without acceptable heart rate control. Of relevance, he had a pacemaker implanted for II grade atrioventricular block. We thought to replace b-blocker with ivabradine (selective inhibitor of If channel), being not possible to increase the dose. To test our purpose we did incremental cardiopulmonary exercise test on cycloergometer (CPET) and constant CPET at the 85% of the maximum work load 3 times:under carvedilol, after 7 days of b-blocker wash out, after 7 days of 5 mg bid ivabradine. We measured VO2peak , anaerobic threshold (AT), minute ventilation (VE), VE/VCO2 slope, heart rate, blood pressure; endurance time (T-lim) at constant CPET. Results are in Table 1. Conclusion: Ivabradine significantly improves T-lim(488 vs 452 vs 606sec) and VE/VCO2slope (31.7 vs 37.8 vs 28.6) and postpones AT (977 vs 1091 vs 1140 mlO2/min). Results may be due to its lower impairment in inotropism and ventilation and to the lower HR at the beginning of exercise.

AIM:To compare the utility of the partners-heart failure (HF) algorithm with the care alert strategy for remote monitoring, in guiding clinical actions oriented to treat impending HF.METHODS:Consecutive cardiac resynchronization-defibrillator recipients were followed with biweekly automatic transmissions. After every transmission, patients received a phone contact in order to check their health status, eventually followed by clinical actions, classified as "no-action", "non-active" and "active". Active clinical actions were oriented to treat impending HF. The sensitivity, specificity, positive and negative predictive values and diagnostic accuracy of the partners-HF algorithm vs care alert in determining active clinical actions oriented to treat pre-HF status and to prevent an acute decompensation, were also calculated.RESULTS:The study population included 70 patients with moderate to advanced systolic HF and QRS duration longer than 120 ms. During a mean follow-up of 8 ± 2 mo, 665 transmissions were collected. No deaths or HF hospitalizations occurred. The sensitivity and specificity of the partners-HF algorithm for active clinical actions oriented to treat impending HF were 96.9% (95%CI: 0.96-0.98) and 92.5% (95%CI: 0.90-0.94) respectively. The positive and negative predictive values were 84.6% (95%CI: 0.82-0.87) and 98.6% (95%CI: 0.98-0.99) respectively. The partners-HF algorithm had an accuracy of 93.8% (95%CI: 0.92-0.96) in determining active clinical actions. With regard to active clinical actions, care alert had a sensitivity and specificity of 11.05% (95%CI: 0.09-0.13) and 93.6% respectively (95%CI: 0.92-0.95). The positive predictive value was 42.3% (95%CI: 0.38-0.46); the negative predictive value was 71.1% (95%CI: 0.68-0.74). Care alert had an accuracy of 68.9% (95%CI: 0.65-0.72) in determining active clinical actions.CONCLUSION:The partners-HF algorithm proved higher accuracy and sensitivity than care alert in determining active clinical actions oriented to treat impending HF. Future studies in larger populations should evaluate partners-HF ability to improve HF-related clinical outcomes.

Atrial fibrillation is the most common arrhythmia in clinical practice. Ion channel blocking agents are often characterized by limited long-term efficacy and several side effects. In addition, ablative invasive procedures are neither easily accessible nor always efficacious. The "upstream therapy," which includes angiotensin-converting enzyme inhibitors, aldosterone receptor antagonists, statins, glucocorticoids, and ω-3 poly-unsaturated fatty acids, targets arrhythmia substrate, influencing atrial structural and electrical remodeling that play an essential role in atrial fibrillation induction and maintenance. The mechanisms involved and the most important clinical evidence regarding the upstream therapy influence on atrial fibrillation are presented in this review. Some open questions are also proposed.

BACKGROUND Inappropriate sinus tachycardia (IST) is characterized by an elevated heart rate (HR) at rest and an exaggerated HR response to physical activity or emotional stress. Beta-blockers and calcium channel blockers are the first-line therapy but sometimes are poorly tolerated due to side effects.OBJECTIVE The purpose of this study was to evaluate the efficacy and safety of ivabradine, a selective inhibitor of the I(f) current of the sinoatrial node, in patients affected by IST.METHODS Eighteen consecutive symptomatic patients (2 men and 16 women; mean age 45 +/- 15 years) affected by IST were enrolled in the study. Every patient underwent resting ECG, 24-hour Holter ECG, and exercise ECG at baseline and at 3-month and 6-month follow-up.RESULTS Sixteen patients (14 women; mean age 41 +/- 14 years) completed the study. Holter ECG assessment showed a significant reduction of medium HR (P <.001) and maximal HR (P <.001, basal vs 3-6 months; P = .02, 3 vs 6 months). Minimal HR slightly decreased at 3 months and then stabilized (P = .49, 3 vs 6 months) despite an increased drug dose. Stress test showed a significant decrease at rest (P <.001) and maximal HR (P <.05), suggesting an increased tolerance to physical stress, which was confirmed by a progressive increase of maximal load reached (>100 W) during stress test at 3 months (75%) and 6 months (85%). One patient was excluded because of phosphenes despite dose lowering, and another patient did not complete the protocol.CONCLUSION Ivabradine could represent an effective and safe alternative to calcium channel blockers and beta-blockers for treatment of IST.
