- Abstract
The arteriovenous fistula (AVF) represents the favorite vascular access in individuals with chronic kidney disease (CKD). Because AVF is a guarantee of survival for these patients, proper surgical packing and a timely follow-up program is crucial. Although a good objective examination of the limb site of FAV provides useful information both in planning the fistula surgery and in its surveillance and monitoring, it is now well established that the advent of instrumental diagnostics (ultrasonography, digital angiography, Angio-TC, MRI) has contributed significantly to improving primary and secondary patency of FAV and early diagnosis of vascular access complications. In this area, clinical thermography, a noninvasive and nondestructive diagnostic technique for assessing minute surface temperature differences, has shown good potential for the assessment of AVF. In fact, thermographic analysis of a limb site of AVF shows an increase in temperature at the site of the anastomosis and along the course of the arterialized vein. In this article we report our experience on the use of thermography in preoperative evaluation and postoperative surgical packing of an AVF. Further studies could validate the use of clinical thermography as a diagnostic technique to be used in the field of hemodialysis vascular accesses., (Copyright by Società Italiana di Nefrologia SIN, Rome,Italy.)

- Abstract
Background: Low-voltage area (LVA) ablation, in addition to pulmonary vein isolation (PVI), has been proposed as a new strategy in patients with atrial fibrillation (AF), but clinical trials have shown conflicting results. We performed a systematic review and meta-analysis to assess the impact of LVA ablation in patient undergoing AF ablation (PROSPERO-registered CRD42024537696). Methods: Randomized clinical trials investigating the role of LVA ablation in addition to PVI in patients with AF were searched on PubMed, Embase, and the Cochrane Library from inception to 22 April 2024. Primary outcome was atrial arrhythmia recurrence after the first AF ablation procedure. Secondary endpoints included procedure time, fluoroscopy time, and procedure-related complication rate. Sensitivity analysis including only patients with LVA demonstration at mapping and multiple subgroups analyses were also performed. Results: 1547 patients from 7 studies were included. LVA ablation in addition to PVI reduced atrial arrhythmia recurrence (odds ratio [OR] 0.65, 95% confidence interval [CI] 0.52-0.81, p < 0.001) with a number needed to treat to prevent recurrence of 10. No difference in procedure time (mean difference [MD] -5.32 min, 95% CI -19.01-8.46 min, p = 0.45), fluoroscopy time (MD -1.10 min, 95% CI -2.48-0.28 min, p = 0.12) and complication rate (OR 0.81, 95% CI 0.40-1.61, p = 0.54) was observed. Consistent results were demonstrated when considering only patients with LVA during mapping and in prespecified subgroups for AF type (paroxysmal vs. persistent), multicentric vs. monocentric trial, and ablation strategy in control group. Conclusions : In patients with AF, ablation of LVAs in addition to PVI reduces atrial arrhythmia recurrence without a significant increase in procedure time, fluoroscopy time, or complication rate.

- Abstract
Social robots represent a valid opportunity to manage the diagnosis, treatment, care, and support of older people with dementia. The aim of this study is to validate the Mini-Mental State Examination (MMSE) test administered by the Pepper robot equipped with systems to detect psychophysical and emotional states in older patients. Our main result is that the Pepper robot is capable of administering the MMSE and that cognitive status is not a determinant in the effective use of a social robot. People with mild cognitive impairment appreciate the robot, as it interacts with them. Acceptability does not relate strictly to the user experience, but the willingness to interact with the robot is an important variable for engagement. We demonstrate the feasibility of a novel approach that, in the future, could lead to more natural human-machine interaction when delivering cognitive tests with the aid of a social robot and a Computational Psychophysiology Module (CPM).

- Abstract
Background: COVID-19 may result in persistent symptoms in the post-acute phase, including cognitive and neurological ones. The aim of this study is to investigate the cognitive and neurological features of patients with a confirmed diagnosis of COVID-19 evaluated in the post-acute phase through a direct neuropsychological evaluation., Methods: Individuals recovering from COVID-19 were assessed in an out-patient practice with a complete neurological evaluation and neuropsychological tests (Mini-Mental State Examination; Rey Auditory Verbal Test, Multiple Feature Target Cancellation Test, Trial Making Test, Digit Span Forward and Backward, and Frontal Assessment Battery). Pre- and post-COVID-19 global and mental health status was assessed along with the history of the acute phase of infection. Post-COVID-19 cognitive status was modeled by combining persistent self-reported COVID-related cognitive symptoms and pathologic neuropsychological tests., Results: A total of 406 individuals (average age 54.5 ± 15.1 years, 45.1% women) were assessed on average at 97.8 ± 48.0 days since symptom onset. Persistent self-reported neurological symptoms were found in the areas of sleep (32%), attention (31%), and memory (22%). The MMSE mean score was 28.6. In total, 84 subjects (20.7%) achieved pathologic neuropsychological test results. A high prevalence of failed tests was found in digit span backward (18.7%), trail making (26.6%), and frontal assessment battery (10.9%). Cognitive status was associated with a number of factors including cardiovascular disease history, persistent fatigue, female sex, age, anxiety, and mental health stress., Conclusion: COVID-19 is capable of eliciting persistent measurable neurocognitive alterations particularly relevant in the areas of attention and working memory. These neurocognitive disorders have been associated with some potentially treatable factors and others that may stratify risk at an early stage., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Lauria, Carfì, Benvenuto, Bramato, Ciciarello, Rocchi, Rota, Salerno, Stella, Tritto, Di Paola, Pais, Tosato, Janiri, Sani, Lo Monaco, Pagano, Fantoni, Bernabei, Landi, Bizzarro and Gemelli Against COVID-19 Post-acute Care Group.)

- Abstract
Ventricular tachycardia in patients with structural heart disease is a significant cause of morbidity and mortality. According to current guidelines, cardioverter defibrillator implantation, antiarrhythmic drugs, and catheter ablation are established therapies in the management of ventricular arrhythmias but their efficacy is limited in some cases. Sustained ventricular tachycardia can be terminated by cardioverter-defibrillator therapies although shocks in particular have been demonstrated to increase mortality and worsen patients' quality of life. Antiarrhythmic drugs have important side effects and relatively low efficacy, while catheter ablation, even if it is actually an established treatment, is an invasive procedure with intrinsic procedural risks and is frequently affected by patients' hemodynamic instability. Stereotactic arrhythmia radioablation for ventricular arrhythmias was developed as bail-out therapy in patients unresponsive to traditional treatments. Radiotherapy has been mainly applied in the oncological field, but new current perspectives have developed in the field of ventricular arrhythmias. Stereotactic arrhythmia radioablation provides an alternative non-invasive and painless therapeutic strategy for the treatment of previously detected cardiac arrhythmic substrate by three-dimensional intracardiac mapping or different tools. Since preliminary experiences have been reported, several retrospective studies, registries, and case reports have been published in the literature. Although, for now, stereotactic arrhythmia radioablation is considered an alternative palliative treatment for patients with refractory ventricular tachycardia and no other therapeutic options, this research field is currently extremely promising.

- Abstract
Background: With the lifetime risk of DFU being 34% and the rate of chronic wounds increasing, there is a need for advanced therapies offering rapid, reliable, and safe healing., Materials and Methods: A retrospective review was performed of 10 cases in which a novel PRBM was used for treatment of chronic DFUs. Patients who presented with DFUs refractory to topical wound care and offloading for longer than 4 weeks received weekly application of PRBM for up to 12 weeks along with a standard treatment regimen at a single outpatient center. At weekly visits, the wound was measured, inspected for signs of complications, cleaned, and debrided as necessary, followed by PRBM application until complete epithelialization or for 12 applications. The primary outcome was complete wound closure at 12 weeks. Secondary outcomes included time to closure, DFU percent area reduction, and material cost to closure., Results: Mean wound healing time was 6.1 weeks, with 90% of wounds closed at 12 weeks. Six wounds were healed at 6 weeks, 2 at 7 weeks, and 1 at 12 weeks. One wound did not close over the study period. Mean wound area reduction was 85% at 6 weeks and 94% at 12 weeks. Patients tolerated PRBM application with no reported pain or discomfort. No adverse events were reported. Mean PRBM cost to closure for healed wounds was $2624., Conclusions: Treatment of chronic DFUs with PRBM is safe and efficient to achieve complete healing.

- Abstract
Cerebral palsy (CP) is a non-progressive neurologic pathology representing a leading cause of spasticity and concerning gait impairments in children. Robotic-assisted gait training (RAGT) is widely employed to treat this pathology to improve children's gait pattern. Importantly, the effectiveness of the therapy is strictly related to the engagement of the patient in the rehabilitation process, which depends on his/her psychophysiological state. The aim of the study is to evaluate the psychophysiological condition of children with CP during RAGT through infrared thermography (IRT), which was acquired during three sessions in one month. A repeated measure ANOVA was performed (i.e., mean value, standard deviation, and sample entropy) extracted from the temperature time course collected over the nose and corrugator, which are known to be indicative of the psychophysiological state of the individual. Concerning the corrugator, significant differences were found for the sample entropy (F (1.477, 5.907) = 6.888; p = 0.033) and for the mean value (F (1.425, 5.7) = 5.88; p = 0.047). Regarding the nose tip, the sample entropy showed significant differences (F (1.134, 4.536) = 11.5; p = 0.041). The findings from this study suggests that this approach can be used to evaluate in a contactless manner the psychophysiological condition of the children with CP during RAGT, allowing to monitor their engagement to the therapy, increasing the benefits of the treatment.

- Abstract
Cerebral palsy (CP) is a non-progressive neurologic condition that causes gait limitations, spasticity, and impaired balance and coordination. Robotic-assisted gait training (RAGT) has become a common rehabilitation tool employed to improve the gait pattern of people with neurological impairments. However, few studies have demonstrated the effectiveness of RAGT in children with CP and its neurological effects through portable neuroimaging techniques, such as functional near-infrared spectroscopy (fNIRS). The aim of the study is to evaluate the neurophysiological processes elicited by RAGT in children with CP through fNIRS, which was acquired during three sessions in one month. The repeated measure ANOVA was applied to the β-values delivered by the General Linear Model (GLM) analysis used for fNIRS data analysis, showing significant differences in the activation of both prefrontal cortex (F (1.652, 6.606) = 7.638; p = 0.022), and sensorimotor cortex (F (1.294, 5.175) = 11.92; p = 0.014) during the different RAGT sessions. In addition, a cross-validated Machine Learning (ML) framework was implemented to estimate the gross motor function measure (GMFM-88) from the GLM β-values, obtaining an estimation with a correlation coefficient r = 0.78. This approach can be used to tailor clinical treatment to each child, improving the effectiveness of rehabilitation for children with CP.

- Abstract
Mental workload (MW) represents the amount of brain resources required to perform concurrent tasks. The evaluation of MW is of paramount importance for Advanced Driver-Assistance Systems, given its correlation with traffic accidents risk. In the present research, two cognitive tests (Digit Span Test-DST and Ray Auditory Verbal Learning Test-RAVLT) were administered to participants while driving in a simulated environment. The tests were chosen to investigate the drivers' response to predefined levels of cognitive load to categorize the classes of MW. Infrared (IR) thermal imaging concurrently with heart rate variability (HRV) were used to obtain features related to the psychophysiology of the subjects, in order to feed machine learning (ML) classifiers. Six categories of models have been compared basing on unimodal IR/unimodal HRV/multimodal IR + HRV features. The best classifier performances were reached by the multimodal IR + HRV features-based classifiers (DST: accuracy = 73.1%, sensitivity = 0.71, specificity = 0.69; RAVLT: accuracy = 75.0%, average sensitivity = 0.75, average specificity = 0.87). The unimodal IR features based classifiers revealed high performances as well (DST: accuracy = 73.1%, sensitivity = 0.73, specificity = 0.73; RAVLT: accuracy = 71.1%, average sensitivity = 0.71, average specificity = 0.85). These results demonstrated the possibility to assess drivers' MW levels with high accuracy, also using a completely non-contact and non-invasive technique alone, representing a key advancement with respect to the state of the art in traffic accident prevention., Competing Interests: The authors declare that they have no conflict of interest.

- Abstract
Objective: Diabetic foot ulcers (DFUs) are characterised by the presence of many microbes, some of which may not be identified by traditional culture techniques. Total contact casting (TCC) remains the gold-standard for offloading, yet little is known about the microbiome of wounds that progress from hard-to-heal to closed within a TCC., Method: A patient with a DFU underwent weekly treatment with TCC to closure. Samples for next-generation sequencing (NGS) and bioinformatics analysis of tissue samples were collected during each visit. Detection, identification, characterisation of the microbial community and abundance of microbes in each sample were compared., Results: Abundance of microbes, identified by species and strain, changed with each treatment visit. By the final week of treatment, species diversity of the wound microbiome had decreased significantly, highlighted by an observed decrease in the number of total microorganisms present. Resistance genes for tetracyclines were detected in the first sample, but not in subsequent samples., Conclusion: The results of this study suggest dynamic microbiological changes associated with DFUs as they progress to healing within a TCC. As NGS becomes more readily available, further studies will be helpful to gain an improved understanding of the significance of the wound microbiome in patients with DFUs.

- Abstract
Background: Optimal timing for catheter ablation of ventricular tachycardia is an important unresolved issue. There are no randomized trials evaluating the benefit of ablation after the first implantable cardioverter defibrillator (ICD) shock., Methods: We conducted a 2-phase, prospective, multicenter, randomized clinical trial. Patients with ischemic or nonischemic dilated cardiomyopathy and primary or secondary prevention indication for ICD were enrolled in an initial observational phase until first appropriate shock (phase A). After reconsenting, patients were randomly assigned 1:1 in phase B to immediate ablation (within 2 months from shock delivery) or continuation of standard therapy. The primary end point was a composite of death from any cause or hospitalization for worsening heart failure. Amiodarone intake was not allowed except for documented atrial tachyarrhythmias. On July 23, 2021, phase B of the trial was interrupted as a result of the first interim analysis on the basis of the Bayesian adaptive design., Results: Of the 517 patients enrolled in phase A, 154 (30%) had ventricular tachycardia, 56 (11%) received an appropriate shock over a median follow-up of 2.4 years (interquartile range, 1.4-4.4), and 47 of 56 (84%) agreed to participate in phase B. After 24.2 (8.5-24.4) months, the primary end point occurred in 1 of 23 (4%) patients in the ablation group and 10 of 24 (42%) patients in the control group (hazard ratio, 0.11 [95% CI, 0.01-0.85]; P =0.034). The results met the prespecified termination criterion of >99% Bayesian posterior probability of superiority of treatment over standard therapy. No deaths were observed in the ablation group versus 8 deaths (33%) in the control group ( P =0.004); there was 1 worsening heart failure hospitalization in the ablation group (4%) versus 4 in the control group (17%; P =0.159). ICD shocks were less frequent in the ablation group (9%) than in the control group (42%; P =0.039)., Conclusions: Ventricular tachycardia ablation after first appropriate shock was associated with a reduced risk of the combined death or worsening heart failure hospitalization end point, lower mortality, and fewer ICD shocks. These findings provide support for considering ventricular tachycardia ablation after the first ICD shock., Registration: URL: https://www., Clinicaltrials: gov; Unique identifier: NCT01547208.

- Abstract
Purpose: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, occurring in 1-2% of the general population. Catheter ablation has become an important treatment modality for patients with symptomatic drug-refractory AF. We report data regarding the AF ablation approaches and modalities in the Italian "real world.", Methods: The survey was set-up to collect data on ablation procedure across Italy. All centers performing AF ablation were invited, regardless of the number of annual procedures, to complete a questionnaire regarding their ablation approaches. All centers reported data regarding procedures performed during the year 2017., Results: A total of 3260 procedures were reported from 49 participating hospitals. Most of Italian regions were included in the study. The majority of the centers performed "Always" pulmonary vein isolation (PVI) in paroxysmal and persistent AF catheter ablation, while adjunctive lesions in persistent AF ablation were planned in most of them but not all, and 16% never performed lesions other than PVI. During ablation procedure, vitamin k inhibitors were uninterrupted in 55% of centers, while direct oral anticoagulant in 44% of centers was used uninterruptedly. No relationship was observed between patient data and the number of procedures performed at each center., Conclusions: This survey suggests that the adherence of Italian centers to the most recent European Society of Cardiology guidelines for AF ablation is reasonably high., (© 2021.

- Abstract
Subungual exostosis (SE) is a benign, relatively uncommon bony growth underneath the nails of the distal phalanx of toes or fingers, with a majority on the toes. Clinically, it has two subvariants-protruded and nonprotruded growths from nail plates-which are treated differently. In this article, we report a case of protruded SE in a teenager with illustrative surgical excision. A 15-year-old boy presented with a painful growth on his right great toe of 6 months' duration. Physical examination revealed a 1-cm-diameter, solid, erythematous, rough, irregular growth penetrating through the skin along the dorsolateral nail bed of the right hallux with deformity of the lateral nail plate. Radiographs showed an elevated mass over the distal phalanx of the right lateral hallux. The mass was surgically excised and histopathologic examination confirmed the diagnosis of SE. The patient had no relapse or recurrence at follow-ups of 6 and 18 months. Subungual exostosis is a relatively uncommon bony growth in the toes. Radiography is favored for the diagnosis. Complete surgical excision is the optimal treatment, with rare recurrence. It needs to be differentiated from other bony lesions, including bizarre parosteal osteochondromatous proliferation, myositis ossificans, fibro-osseous pseudotumor, osteochondroma, and enchondroma.

- Abstract
Eumycetoma, caused by fungi, is a neglected tropical disease. It is endemic in the "mycetoma belt" countries but rare in North America. We report a case of pedal eumycetoma in the state of Maryland. A 51-year-old male immigrant from Guatemala presented with multiple, enlarging nodules on the dorsal surface of his left great toe present for 1 year, and a new one in the left arch area present for 6 months. The nodular lesions were surgically excised in two separate operations. Pathologic evaluation of all nodules revealed eumycetomas characterized by the Splendore-Hoeppli phenomenon, showing an amorphous eosinophilic center filled with numerous fungal hyphae, observed on periodic acid-Schiff-stained slides, with a surrounding cuff of neutrophils. Polymerase chain reaction-based sequencing identified Cladosporium cladosporioides in the tissues. The patient was further treated with oral fluconazole for 2 months. The patient recovered well postoperatively and had no recurrence at 20-month follow-up. In conclusion, even though eumycetoma is regarded as a rare disease in North America, its incidence may be higher than reported because of millions of immigrants from endemic regions in the United States, which highlights the need to raise awareness of this devastating disease in the medical community. Eumycetoma needs to be differentiated from other infectious and noninfectious benign and malignant lesions. Optimal treatment includes surgical excision with antifungal therapy.

Objectives: Symptom persistence weeks after laboratory-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) clearance is a relatively common long-term complication of Coronavirus disease 2019 (COVID-19). Little is known about this phenomenon in older adults. The present study aimed at determining the prevalence of persistent symptoms among older COVID-19 survivors and identifying symptom patterns., Design: Cross-sectional study., Setting and Participants: We analyzed data collected in people 65 years and older (n = 165) who were hospitalized for COVID-19 and then admitted to the Day Hospital Post-COVID 19 of the Fondazione Policlinico Universitario "Agostino Gemelli" IRCCS (Rome, Italy) between April and December 2020. All patients tested negative for SARS-CoV-2 and met the World Health Organization criteria for quarantine discontinuation., Measures: Patients were offered multidisciplinary individualized assessments. The persistence of symptoms was evaluated on admission using a standardized questionnaire., Results: The mean age was 73.1 ± 6.2 years (median 72, interquartile range 27), and 63 (38.4%) were women. The average time elapsed from hospital discharge was 76.8 ± 20.3 days (range 25-109 days). On admission, 137 (83%) patients reported at least 1 persistent symptom. Of these, more than one-third reported 1 or 2 symptoms and 46.3% had 3 or more symptoms. The rate of symptom persistence was not significantly different when patients were stratified according to median age. Compared with those with no persistent symptoms, patients with symptom persistence reported a greater number of symptoms during acute COVID-19 (5.3 ± 3.0 vs 3.3 ± 2.0; P < .001). The most common persistent symptoms were fatigue (53.1%), dyspnea (51.5%), joint pain (22.2%), and cough (16.7%). The likelihood of symptom persistence was higher in those who had experienced fatigue during acute COVID-19., Conclusions and Implications: Persistent symptoms are frequently experienced by older adults who have been hospitalized for COVID-19. Follow-up programs should be implemented to monitor and care for long-term COVID-19-related health issues., (Copyright © 2021 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

- Abstract
Background: In East Asia, face masks are commonly worn to reduce viral spread. In Euope and North America, however, their use has been stigmatised for a long time, although this view has radically changed during the ongoing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. Notwithstanding this, it is still unclear whether face masks worn by COVID-19 carriers may indeed prevent viral transmission and environmental contamination. The objective of this study was to evaluate the effectiveness of surgical face masks in filtering SARS-CoV-2., Methods: Four male patients with COVID-19 were recruited for the study. Two patients wore a surgical mask for 5 h, while two others did not. The spread of the virus in the environment was evaluated through the approved Allplex 2019-nCoV assay., Results: In the room with the two patients without surgical masks, the swab performed on the headboard and sides of the beds was positive for SARS-CoV-2 contamination. In the other room, where two patients were wearing surgical masks, all of the swabs obtained after 5 h tested negative., Conclusions: The results of the current study add to the growing body of literature supporting the use of face masks as a measure to contain the spread of SARS-CoV-2 by retaining potentially contagious droplets that can infect other people and/or contaminate surfaces. Based on the current evidence, face masks should therefore be considered a useful and low-cost device in addition to social distancing and hand hygiene during the postlockdown phase., (© The Author(s) 2020.

- Abstract
Introduction: As an emerging infectious disease, the clinical and virologic course of COVID-19 requires better investigation. The aim of this study is to identify the potential risk factors associated with persistent positive nasopharyngeal swab real-time reverse transcription‒polymerase chain reaction tests in a large sample of patients who recovered from COVID-19., Methods: After the acute phase of SARS-CoV-2 epidemic infection, the Fondazione Policlinico A. Gemelli IRCSS of Rome established a post-acute care service for patients discharged from the hospital and recovered from COVID-19. Between April 21 and May 21, 2020, a total of 137 individuals who officially recovered from COVID-19 were enrolled in this study. All patients were tested for the SARS-CoV-2 virus with nucleic acid RT-PCR tests. Analysis was conducted in June 2020., Results: Of the 131 patients who repeated the nasopharyngeal swab, 22 patients (16.7%) tested positive again. Some symptoms such as fatigue (51%), dyspnea (44%), and coughing (17%) were still present in a significant percentage of the patients, with no difference between patients with a negative test and those who tested positive. The likelihood of testing positive for SARS-CoV-2 infection was significantly higher among participants with persistent sore throat (prevalence ratio=6.50, 95% CI=1.38, 30.6) and symptoms of rhinitis (prevalence ratio=3.72, 95% CI=1.10, 12.5)., Conclusions: This study is the first to provide a given rate of patients (16.7%) who test positive on RT-PCR test for SARS-CoV-2 nucleic acid after recovering from COVID-19. These findings suggest that a significant proportion of patients who have recovered from COVID-19 still could be potential carriers of the virus. In particular, if patients continue to have symptoms related to COVID-19, such as sore throat and rhinitis, it is reasonable to be cautious by avoiding close contact, wearing a face mask, and possibly repeating a nasopharyngeal swab., (Copyright © 2020 American Journal of Preventive Medicine.

- Abstract
Aim: To report the Italian data deriving from the European Society of Cardiology-EURObservational Research Program atrial fibrillation ablation long-term registry., Methods and Results: Ten Italian centers enrolled up to 50 consecutive patients undergoing atrial fibrillation ablation. Of the 318 patients included, 5 (1.6%) did not undergo catheter ablation, 1 had ablation partially done and 62 were lost at 1-year follow-up. Women were less represented (23.6%) and the median age was 60.0 years. A total of 195 patients (62.3%) suffered paroxysmal atrial fibrillation, whereas only 9 (2.9%) had long-standing persistent atrial fibrillation. Most Italian patients (92.3%) were symptomatic but suffering fewer symptomatic events than patients enrolled in other countries (median of two events in the month preceding the ablation vs. three, respectively; P < 0.0001). The main finding of the study is that the success rate at 1 year, with and without antiarrhythmic drugs, was 76.4%, consistently with other participating countries (73.4%). This result was obtained however, with a significantly lower prevalence of 1-year adverse events (7.3 vs. 16.6%, P < 0.0001). Procedure duration and fluoroscopy total time resulted as being shorter in Italy (145 vs. 160, P = 0.0005 and 16.9 vs. 20.0 min, P = 0.0018, respectively); however, the radiation dose per BSA was greater (37.5 vs. 26.0 mGy/cm, P = 0.0022)., Conclusion: The demographic characteristics of patients undergoing atrial fibrillation ablation are similar to those reported in other countries. The success rate in Italy is consistent with those in other countries, whereas the complications rate is lower.

- Abstract
On February 20, 2020, a man living in the north of Italy was admitted to the emergency room with an atypical pneumonia that later proved to be COVID-19. This was the trigger of one of the most serious clusters of COVID-19 in the world, outside of China. Despite aggressive restraint and inhibition efforts, COVID-19 continues to increase, and the total number of infected patients in Italy is growing daily. After 6 weeks, the total number of patients reached 128,948 cases (April 5, 2020), with the higher case-fatality rate (15,887 deaths) dominated by old and very old patients. This sudden health emergency severely challenged the Italian Health System, in particular acute care hospitals and intensive care units. In 1 hospital, geriatric observation units were created, the experience of which can be extremely useful for European countries, the United States, and all countries that in the coming days will face a similar situation., (Copyright © 2020 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

- Abstract
Onychomycosis is a common world-wide health issue. Accurate detection is essential for treatment. Multiple studies have shown that PAS-stain based histological visualization of fungal elements is superior to either direct microscopy with 20% potassium hydroxide, or fungal culture. However, PAS stain based histological classification and severity grading of onychomycosis are lacking in the literature. Here we reported a fungal detection rate of 47.87% based on an analysis of 13,805 toenails processed for H&E and PAS stains over a three year period. Based on the analysis of fungal density, distribution and infiltrating depth level in 858 PAS-positive toenails, we created a novel PAS stain based histological classification system to classify onychomycosis as occult onychomycosis (OO), focal or diffuse subungual onychomycosis (FSO or DSO), focal or diffuse plate onychomycosis (FPO or DPO), focal or diffuse subungual and plate onychomycosis (FSPO or DSPO) and superficial onychomycosis (SO). The severities of OO, FSO and FPO were graded as mild, DSO and DPO as moderate, FSPO and DSPO as severe infections, which revealed that more than 75% PAS positive toenails were severe infections. Evaluation of 97 paired toenails biopsied pre- and post-treatment from 47 patients demonstrated that the severity of infection was significantly reduced from severe to mild and moderate levels. These data indicate that the current histological classification evaluates not only the severity of the fungal infection but also the response to treatment. We further propose a guideline for treatment of onychomycosis based on the histological classification and severity., (© The Author(s) 2019.

- Abstract
Aims: Monitoring of patients after ablation had wide variations in the ESC-EHRA atrial fibrillation ablation long-term (AFA-LT) registry. We aimed to compare four different monitoring strategies after catheter AF ablation., Methods and Results: The ESC-EHRA AFA-LT registry included 3593 patients who underwent ablation. Arrhythmia monitoring during follow-up was performed by 12-lead electrocardiogram (ECG), Holter ECG, trans-telephonic ECG monitoring (TTMON), or an implanted cardiac monitoring (ICM) system. Patients were selected to a given monitoring group according to the most extensive ECG tool used in each of them. Comparison of the probability of freedom from recurrences was performed by censored log-rank test and presented by Kaplan-Meier curves. The rhythm monitoring methods were used among 2658 patients: ECG (N = 578), Holter ECG (N = 1874), TTMON (N = 101), and ICM (N = 105). A total of 767 of 2658 patients (28.9%) had AF recurrences during follow-up. Censored log-rank test discovered a lower probability of freedom from relapses, which was detected with ICM compared to TTMON, ECG, and Holter ECG (P < 0.001). The rate of freedom from AF recurrences was 50.5% among patients using the ICM while it was 65.4%, 70.6%, and 72.8% using the TTMON, ECG, and Holter ECG, respectively., Conclusion: Comparing all main electrocardiographic monitoring methods in a large patient sample, our results suggest that post-ablation recurrences of AF are significantly underreported by TTMON, ECG, and Holter ECG. The ICM estimates AF ablation recurrences most reliably and should be a preferred mode of monitoring for trials evaluating novel AF ablation techniques., (Published on behalf of the European Society of Cardiology.

- Abstract
Background: In patients with coronary artery disease, ventricular tachycardia (VT) is usually related to left ventricular (LV) post-infarction scars., Case Summary: A case of a 78-year-old man with post-infarction VT originating from the right ventricular (RV) free wall is described. Following recurrent episodes of VT with left bundle branch block morphology and left superior axis deviation, a patient with prior myocardial infarction was submitted to catheter ablation. Two areas of abnormal bipolar electrograms were observed at 3D electroanatomical mapping: one located at the basal aspect of the posterior and postero-septal LV, and the other one extending from the antero-lateral to the posterior mid-basal RV free wall. Ventricular late potentials (LPs) were recorded within both scars, but only pacing from those located in the RV resulted in long stimulus-to-QRS latency and optimal pace-mapping. Accordingly, this substrate was deemed the culprit of the clinical VT. Radiofrequency catheter ablation aimed at eliminating all LPs recorded from both scars was effective in preventing VT recurrences at follow-up., Discussion: A post-infarction RV free-wall scar may exceptionally be responsible of VT occurrence. Right ventricular mapping should be considered in selected cases based on 12-lead electrocardiogram VT morphology and prior RV infarct., (© The Author(s) 2019.

- Abstract
Aims: Ablation procedures for the treatment of atrial fibrillation lead to changes in autonomic heart control; however, there are insufficient data on the possible association of these changes with atrial fibrillation recurrence. The study aim was to assess the effects of pulmonary vein isolation (PVI) on cardiac autonomic modulation and atrial fibrillation recurrence., Methods: We screened 52 patients with atrial fibrillation referred for PVI, of whom 20 patients met inclusion and exclusion criteria, and were enrolled in the study and followed over 6 months. Beat-to-beat blood pressure monitoring was performed 1-2 days before PVI, 1 and 6 months after PVI. We estimated pulse interval variability and spontaneous baroreflex sensitivity (BRS) both in the time and frequency domains, and performed the Valsalva manoeuvre assessing the Valsalva ratio., Results: During 6 months after PVI, atrial fibrillation recurrence was observed in six patients. One month after PVI, pulse interval variability and BRS (sequence method) significantly decreased in all patients, returning to preintervention values by 6 months. Patients without atrial fibrillation recurrence at 1 month showed a transient reduction in pulse interval variability (frequency domain) and in BRS (both methods) in contrast to those with atrial fibrillation recurrence. A significant decrease in the Valsalva ratio observed at 1 month was maintained at 6 months after PVI in both groups., Conclusion: Successful PVI may lead to transient autonomic alterations reflected by a reduction in pulse interval variability and BRS, with more prolonged changes in the Valsalva ratio. The efficacy of PVI in preventing atrial fibrillation recurrence seems to be related to transient parasympathetic atrial denervation.

- Abstract
Background: Cancer patients hospitalized for an acute medical illness are considered to be at high risk of venous thromboembolism (VTE). Information on bleeding and symptomatic VTE in these patients remains scant. The objectives of this study were to evaluate the incidence of bleeding and VTE during hospitalization and after discharge in a prospective cohort of hospitalized medically-ill cancer patients., Methods: Consecutive patients with active cancer admitted for an acute medical illness. The primary outcome was the incidence of clinically relevant bleeding. Secondary outcomes included symptomatic and incidentally detected VTE. Outcomes were recorded during hospitalization up to three months after discharge., Results: The study population consisted of 330 patients with a mean age of 73.2 (±12.1) years. During a median hospitalization of eight days, six patients (1.8%) developed a clinically relevant bleeding. Pharmacological thromboprophylaxis was administered to four of these six patients (66.6%), and 108 of 324 (33.3%) patients without bleeding. Twelve (3.6%) were diagnosed with VTE, of whom two had received thromboprophylaxis. In ten patients, VTE was detected incidentally. After discharge, 11 patients experienced major bleeding and two developed symptomatic VTE during a median follow-up of 92 days (range 19-110). Two thirds of all major bleeding events were gastrointestinal, and 87% occurred in patients with gastrointestinal or genitourinary cancer., Conclusions: In patients with active cancer admitted for an acute medical illness, the risk of bleeding and symptomatic VTE appeared to be low during hospitalization. After discharge, the risk of bleeding was higher and significantly outweighed that of VTE., (Copyright © 2018 Elsevier Ltd. All rights reserved.)

Introduction: Correlation between symptoms and atrial fibrillation (AF) episodes after catheter ablation may have clinical relevance, especially for anticoagulation usage. The aim of our project was to analyze the relationship between symptoms and AF recurrences in unselected patients following AF catheter ablation during long-term follow-up., Methods and Results: One hundred and forty-three consecutive patients (mean age 59 ± 9 years, 85% male) were implanted with a continuous cardiac monitor (RevealXT, Medtronic Inc., Minneapolis, MN, USA) following first pulmonary vein ablation procedure. Device data were downloaded every 3 months and correlated to patients' symptom diary. AF was paroxysmal in 55% and persistent in 45%. At a mean follow-up of 14 ± 6 months, 98/143 (69%) patients had at least one AF recurrence. Among these, 53 (54%) reported AF-related symptoms while 45 (46%) were totally asymptomatic. Conversely, 13 (29%) out of 45 patients without AF recurrences reported symptoms. Globally, a significant reduction of symptoms (from 82% at baseline to 44% at last follow-up; P < 0.0001) was observed. SF-12 questionnaire showed a significant improvement of physical and mental functioning (respectively 44.5 ± 8.5 vs 51.0 ± 6.7, and 45.7 ± 9.3 vs 49.2 ± 6.1, P < 0.05 baseline vs last follow-up). At the 12-month follow-up, 80% and 77% of patients were on AAD and anticoagulant drugs, respectively. There were not differences in AAD usage in symptomatic and asymptomatic patients., Conclusions: Continuous ECG monitoring is a valuable tool for long-term follow-up after AF catheter ablation facilitating reliable assessment of symptomatic and asymptomatic AF episodes. This may have clinical implications with regards to anticoagulation therapy in high-risk patients., (© 2013 Wiley Periodicals, Inc.)

- Abstract
Antiarrhythmic agents are among the therapeutic options available for the treatment of atrial fibrillation when a rhythm control strategy is required. Although their efficacy seems to be generally comparable to that of nonpharmacological interventions, the use of these agents remains controversial. In particular, among this class of drugs, the use of dronedarone in clinical practice is a matter of debate. In this paper, the authors aimed to address these issues, involving a team of expert cardiologists who discussed about the potential use of dronedarone in different clinical scenarios. The RAND/UCLA appropriateness method was used to develop appropriateness measures for the optimal management of patients treated with dronedarone, by combining the best available scientific evidence with the collective judgment of experts. To this purpose, a group of experts was identified and asked to rate the benefit-to-harm ratio of 52 clinical scenarios. Each indication was classified as "appropriate", "uncertain" or "inappropriate" in accordance with the panelists' median score. The classification of each scenario has led to the development of several recommendations for clinical practice. The use of dronedarone for the management of paroxysmal and persistent atrial fibrillation has evolved over time: this antiarrhythmic drug appears to be useful not only in monitoring symptoms, but also in reducing hospitalization and mortality rates in patients with atrial fibrillation.

Introduction: Despite catheter ablation (CA) becoming an accepted treatment option for symptomatic, drug-resistant atrial fibrillation (AF), safety of this procedure continues to be cause for concern. Aim of the present multicenter registry was to assess the incidence of early CA complications and detect their predictors in a contemporary, unselected AF population, Methods and Results: From January 1, 2011 to December 31, 2011, data from 2,323 consecutive patients who underwent CA (median age 60 [52-67]; 72.3% male) for AF in 29 Italian centers were collected. All major complications occurring to the patient from admission to 30th postprocedural day were recorded. No procedure-related death was observed. Major complications occurred in 94 patients (4.0%): 50 patients (2.2%) suffered vascular access complications; 12 patients (0.5%) developed cardiac tamponade; 14 patients (0.6%) presented with pericarditis; 5 patients (0.2%) had transient ischemic attack; 4 patients had stroke; 3 patients (0.1%) had phrenic nerve paralysis; 3 patients (0.1%) had hemothorax. Other isolated but serious adverse events were documented in 3 patients (0.1%). Female gender (OR 2.643; 95% CI 1.686-4.143; P < 0.0001) and longer procedural duration (OR 2.195; 95% CI 1.388-3.473; P < 0.001) independently predicted a higher risk of complications., Conclusion: Major complications occurred in 4.0% of the CA procedures for AF, with vascular access complications being the most frequent events., (© 2013 Wiley Periodicals, Inc.)

- Abstract
Aims: Survival prediction by the Seattle Heart Failure Model (SHFM) of patients treated with cardiac resynchronization therapy (CRT) remains ill defined. The performance of the SHFM in this clinical setting was therefore evaluated., Methods and Results: Data from 1309 consecutive CRT patients (five centres) were collected retrospectively; 1139 of these patients were considered for analysis. Three-hundred and seven deaths occurred over 40.1 months (interquartile range 25.2-60.0 months; mean event rate 9.7%/year; survival of 89, 81, and 64% at 1, 2, and 5 years). Kaplan-Meier event-free survival analysis stratified according to tertile of SHFM score was significant (log rank test P < 0.001). High-risk tertile (T1) survival was 82, 67, and 46% at 1, 2, and 5 years, respectively. Observed compared with SHFM-predicted survival was 0.11 vs. 0.08, 0.19 vs. 0.16, and 0.36 vs. 0.36, at 1, 2, and 5 years. Model discrimination by c-statistic was 0.64; the logistic models' area under the receiver operating characteristic curve (AUC-ROC) of risk tertiles was 0.66, 0.68, and 0.67, at 1, 2, and 5 years. Compared with the other two groups, T1 was globally more compromised. Within the T1 group, independent predictors of death were male gender, ischaemic heart failure aetiology, lower body weight, and CRT pacemaker., Conclusions: SHFM performance was found to be modest, tending to overestimate survival. However, SHFM identified a high-risk, globally more compromised patient subgroup, hence supporting a comprehensive approach, which should include nutritional, metabolic, and immunological aspects, as well as defibrillator back-up.

- Abstract
Objectives: The purpose of this study is to assess the effectiveness of defibrillation testing (DT) in patients undergoing implantable cardioverter-defibrillator (ICD) insertion., Background: Although DT is considered a standard procedure during ICD implantation, its usefulness has not been definitively proven., Methods: The SAFE-ICD (Safety of Two Strategies of ICD Management at Implantation) study is a prospective observational study designed to evaluate the outcome of 2 strategies: performing defibrillation testing (DT+) versus not performing defibrillation testing (DT-) during de novo ICD implants. No deviation from the centers' current practice was introduced. In all, 2,120 consecutive patients (836 DT+ and 1,284 DT-) age ≥18 years were enrolled at 41 Italian centers from April 2008 to May 2009 and followed up for 24 months until June 2011. The primary endpoint was a composite of severe complications at ICD implant and sudden cardiac death or resuscitation at 2 years., Results: The primary endpoint occurred in 34 patients: 12 intraoperative complications (8 in DT+ group; 4 in DT- group) and 22 during follow-up (10 in DT+ group; 12 in DT- group). Overall, the estimated yearly incidence (95% confidence interval) was DT+ 1.15% (0.73 to 1.83) and DT- 0.68% (0.42 to 1.12). The difference between the 2 groups was negligible: 0.47% per year (-0.15 to 1.10). Mortality from any cause was similar at 2 years (adjusted hazard ratio: 0.97 [0.76 to 1.23], p = 0.80)., Conclusions: In this large cohort of new ICD implants, event rates were similar and extremely low in both groups. These data indicate a limited clinical relevance for DT testing, thus supporting a strategy of omitting DT during an ICD implant.

- Abstract
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and significantly impact patients' quality of life, morbidity and mortality. The number of affected patients is expected to increase as well as the costs associated with AF management, mainly driven by hospitalizations. Over the last decade, catheter ablation techniques targeting pulmonary vein isolation have demonstrated to be effective in treating AF and preventing AF recurrence. This Health Technology Assessment report of the Italian Association of Arrhythmology and Cardiac Pacing (AIAC) aims to define the current role of catheter ablation of AF in terms of effectiveness, efficiency and appropriateness. On the basis of an extensive review of the available literature, this report provides (i) an overview of the epidemiology, clinical impact and socio-economic burden of AF; (ii) an evaluation of therapeutic options other than catheter ablation of AF; and (iii) a detailed presentation of clinical outcomes and cost-benefit ratio associated with catheter ablation. The costs of catheter ablation of AF in Italy were obtained using a bottom-up analysis of a resource utilization survey of 52 hospitals that were considered a representative sample, including 4 Centers that contributed with additional unit cost information in a separate questionnaire. An analysis of budget impact was also performed to evaluate the impact of ablation on the management costs of AF. Results of this analysis show that (1) catheter ablation is effective, safe and superior to antiarrhythmic drug therapy in maintaining sinus rhythm; (2) the cost of an ablation procedure in Italy typically ranges from €8868 to €9455, though current reimbursement remains insufficient, covering only about 60% of the costs; (3) the costs of follow-up are modest (about 8% of total costs); (4) assuming an adjustment of reimbursement to the real cost of an ablation procedure and a 5-10% increase in the annual rate of ablation procedures, after approximately 5-6 years this would result in significant incremental savings for the Italian Healthcare System. In conclusion, catheter ablation of AF is a cost-effective procedure that is inadequately reimbursed in Italy. Insufficient reimbursement may serve as disincentive to perform AF ablation, thereby limiting patient access to this treatment. Considering the healthcare system perspective, higher initial costs for ablation procedures in the short term may be offset by cost savings mainly associated with decreased hospitalizations over time.

- Abstract
Aims: Implantable cardioverter defibrillators (ICD) improve survival in selected patients with left ventricular dysfunction or heart failure (HF). The objective is to estimate the number of ICD candidates and to assess the potential impact on public health expenditure in Italy and the USA., Methods and Results: Data from 3513 consecutive patients (ALPHA study registry) were screened. A model based on international guidelines inclusion criteria and epidemiological data was used to estimate the number of eligible patients. A comparison with current ICD implant rate was done to estimate the necessary incremental rate to treat eligible patients within 5 years. Up to 54% of HF patients are estimated to be eligible for ICD implantation. An implantation policy based on guidelines would significantly increase the ICD number to 2671 implants per million inhabitants in Italy and to 4261 in the USA. An annual increment of prophylactic ICD implants of 20% in the USA and 68% in Italy would be necessary to treat all indicated patients in a 5-year timeframe., Conclusion: Implantable cardioverter defibrillator implantation policy based on current evidence may have significant impact on public health expenditure. Effective risk stratification may be useful in order to maximize benefit of ICD therapy and its cost-effectiveness in primary prevention.

- Abstract
Aims: The purpose of this study was to evaluate adherence to national guidelines on the non-pharmacologic (ablative) treatment of atrial fibrillation (AF)., Methods and Results: This prospective, observational, transversal study enrolled 1256 consecutive in- and outpatients referred to 43 cardiology departments between 1 and 31 October 2008 for the management of AF as a primary diagnosis. A rhythm-control strategy (cardioversion, antiarrhythmic medication, pace-maker implantation, substrate ablation, alone or in combination) was prescribed in 865 (69%) of the patients and a rate-control strategy [drugs, atrioventricular junction ablation and pace-maker implantation (Ablate and Pace)] in 285 (23%). Specifically, substrate catheter ablation was indicated by the attending cardiologist in 187 (14.9%) patients and Ablate and Pace in 29 (2.3%). According to guideline indications, substrate catheter ablation would have been indicated in 183 (14.6%) patients, but only 105 (57%) of these were correctly identified by the attending cardiologist (K statistics for agreement for indications 0.49). Atrioventricular junction ablation and pace-maker implantation would have been indicated in 108 (8.6%) patients, but only 29 (27%) of these were correctly identified by the attending cardiologist (K statistics for agreement for indications 0.06)., Conclusion: About a quarter of patients referred to cardiology departments for AF management have potential indications for non-pharmacological treatment according to the guidelines. Substrate catheter ablation was offered by the attending cardiologist in a percentage similar to that expected, but concordance with guideline indications was moderate. Atrioventricular junction ablation and pace-maker implantation was largely underused.

- Abstract
Background: Several studies have searched for predictors of clinical outcome in patients with heart failure (HF). However, since they were collected in clinical trials, most data were subject to selection biases and do not specifically apply to patients with nonischemic heart disease. This study examined the impact of several variables on combined all-cause mortality and hospitalization for cardiac causes, in consecutive ambulatory patients with HF included in the ALPHA registry., Methods and Results: This analysis included 446 patients with HF and nonischemic heart disease, in New York Heart Association functional class II or III, and a left ventricular (LV) ejection fraction below 40%. In 126 patients (73%) the disease was idiopathic dilated cardiomyopathy, in 72 (16%) hypertensive, in nine (2%) valvular, and in 39 (9%) of other etiologies. The median age was 61 years (range 51-69 years) and 349 (78%) patients were men. Over a median follow-up of 31 months (range 23-40), 82 patients (18%) died or were hospitalized for cardiac causes. In a proportional hazard (Cox) regression model, maximal oxygen consumption (HR 0.9, P = 0.001), LV end-diastolic diameter (HR 1.07, P < 0.001), resting systolic blood pressure (HR 0.97, P < 0.005), and hemoglobin (HR 0.86, P < 0.05) were independent predictors of the combined study endpoint., Conclusions: In an unselected population of patients with HF and nonischemic heart disease, a reduced exercise capacity, large LV end-diastolic diameter, low systolic blood pressure, and hemoglobin were correlated with long-term all-cause mortality or hospitalization for cardiac causes. These observations may help stratifying and tailoring the treatment of patients with HF and nonischemic heart disease.

- Abstract
Objectives: The aim of this study was to assess the prognostic value of T-wave alternans (TWA) in New York Heart Association (NYHA) functional class II/III patients with nonischemic cardiomyopathy and left ventricular ejection fraction (LVEF) < or =40%., Background: There is a strong need to identify reliable risk stratifiers among heart failure candidates for implantable cardioverter-defibrillator (ICD) prophylaxis. T-wave alternans may identify low-risk subjects among post-myocardial infarction patients with depressed LVEF, but its predictive role in nonischemic cardiomyopathy is unclear., Methods: Four hundred forty-six patients were enrolled and followed up for 18 to 24 months. The primary end point was the combination of cardiac death + life-threatening arrhythmias; secondary end points were total mortality and the combination of arrhythmic death + life-threatening arrhythmias., Results: Patients with abnormal TWA (65%) compared with normal TWA (35%) tests were older (60 +/- 13 years vs. 57 +/- 12 years), were more frequently in NYHA functional class III (22% vs. 19%), and had a modestly lower LVEF (29 +/- 7% vs. 31 +/- 7%). Primary end point rates in patients with abnormal and normal TWA tests were 6.5% (95% confidence interval [CI] 4.5% to 9.4%) and 1.6% (95% CI 0.6% to 4.4%), respectively. Unadjusted and adjusted hazard ratios were 4.0 (95% CI 1.4% to 11.4%; p = 0.002) and 3.2 (95% CI 1.1% to 9.2%; p = 0.013), respectively. Hazard ratios for total mortality and for arrhythmic death + life-threatening arrhythmias were 4.6 (p = 0.002) and 5.5 (p = 0.004), respectively; 18-month negative predictive values for the 3 end points ranged between 97.3% and 98.6%., Conclusions: Among NYHA functional class II/III nonischemic cardiomyopathy patients, an abnormal TWA test is associated with a 4-fold higher risk of cardiac death and life-threatening arrhythmias. Patients with normal TWA tests have a very good prognosis and are likely to benefit little from ICD therapy.

- Abstract
Introduction: We report the case of a 49-year-old male patient with recurrent palpitations and two different supraventricular reciprocating tachycardias due to atrioventricular (AV) nodal reentry and orthodromic AV reentry sustained by a left-sided, concealed AV accessory pathway (AP)., Methods and Results: During the baseline electrophysiological study, dual AV nodal conduction (90 ms jump) and non-decremental, eccentric, ventriculo-atrial conduction due to a left-sided, unidirectional, postero-septal AP were documented. Both typical AV nodal reentrant and orthodromic AV reentrant tachycardias were induced by programmed electrical stimulation. In both cases, shift and sustained conduction over the AV "slow pathway" were required for tachycardia induction and maintenance, respectively. Accordingly, catheter ablation was performed by targeting the AV nodal "slow pathway" first with radiofrequency current applications delivered at the inferior portion of the Koch's triangle. Irritative, slow-rate junctional rhythm was observed during ablation. Afterward, programmed electrical stimulation demonstrated a continuous AV nodal conduction curve, persistent conduction over the AP, and only single orthodromic AV echo beat inducible under baseline condition and pharmacological stress (atropine 0.02 mg/kg i.v. bolus and continuous isoprenaline i.v. administration). Sustained reentrant tachycardias were not inducible any more. For these reasons, the procedure was stopped without any attempt to ablate the AP. After a 4 years follow-up the patient is still asymptomatic without antiarrhythmic drug usage., Conclusion: AV nodal "slow pathway" ablation may abolish both typical AV nodal reentry tachycardia and orthodromic AV reentry tachycardia induction when the latter arrhythmia is dependent from AV nodal "slow pathway" conduction for induction and maintenance. This ablation strategy could be considered, under some instances (e.g. right antero-septal accessory pathways, older patients, etc), in order to reduce the procedure risks due to multiple arrhythmia substrate ablations.

- Abstract
Background: Studies reporting the long-term survival of patients treated with cardiac resynchronization therapy (CRT) outside the realm of randomized controlled trials are still lacking. The aim of this study was to quantify the survival of patients treated with CRT in clinical practice and to investigate the long-term effects of CRT on clinical status and echocardiographic parameters., Methods: The study population consisted of 317 consecutive patients with implanted CRT devices from eight Italian University/Teaching Hospitals. The patients were enrolled in a national observational registry and had a minimum follow-up of 2 years. A visit was performed in surviving patients and mortality data were obtained by hospital file review or direct telephone contact., Results: During the study period, 83 (26%) patients died. The rate of all-cause mortality was significantly higher in ischemic than nonischemic patients (14% vs 8%, P = 0.002). Multivariate analysis showed that ischemic etiology (HR 1.72, CI 1.06-2.79; P = 0.028) and New York Heart Association (NYHA) class IV (HR 2.87, CI 1.24-6.64; P = 0.014) were the strongest predictors of all-cause mortality. The effects of CRT persisted at long-term follow-up (for at least 2 years) in terms of NYHA class improvement, increase of left ventricular ejection fraction, decrease of QRS duration (all P = 0.0001), and reduction of left ventricular end-diastolic and end-systolic diameters (P = 0.024 and P = 0.011, respectively)., Conclusions: During long-term (3 years) follow-up after CRT, total mortality rate was 10%/year. The outcome of ischemic patients was worse mainly due to a higher rate of death from progressive heart failure. Ischemic etiology along with NYHA class IV was identified as predictors of death. Benefits of CRT in terms of clinical function and echocardiographic parameters persisted at the time of long-term follow-up.
