RESUMO
BACKGROUND: Axillary vein puncture (AVP) is a valid alternative to Subclavan vein puncture for leads insertion in cardiac implantable electronic device implantation, that may reduce acute and delayed complications. Very few data are available about ICD recipients. A simplified AVP technique is described. METHODS: All the patients who consecutively underwent "de novo" ICD implantation, from March 2006 to December 2020 at the University of Verona, were considered. Leads insertion was routinely performed through an AVP, according to a simplified technique. Outcome and complications have been retrospectively analyzed. RESULTS: The study population consisted of 1711 consecutive patients. Out of 1711 patients, 38 (2.2%) were excluded because they were implanted with Medtronic Sprint Fidelis lead. Out of 1673 ICD implantations, 963 (57.6%) were ICD plus cardiac resynchronization therapy, 434 (25.9%) were dual-chamber defibrillators, and 276 (16.5%) were single-chamber defibrillators, for a total of 3879 implanted leads. The AVP success rate was 99.4%. Acute complications occurred in 7/1673 (0.42%) patients. Lead failure (LF) occurred in 20/1673 (1.19%) patients. Comparing the group of patients with lead failure with the group without LF, the presence of three leads inside the vein was significantly associated with LF, and the multivariate analysis confirmed three leads in place as an independent predictor of LF. CONCLUSION: AVP, according to our simplified technique, is safe, effective, has a high success rate, and a very low complication rate. The incidence of LF was exceptionally low. The advantages of AVP are maintained over time in a population of ICD recipients.

Background: After an embolic stroke of undetermined source (ESUS), long-term monitoring is recommended to start an anticoagulation therapy in patients with documented atrial fibrillation (AF). Literature is sparse about the AF burden following an ESUS, although this might have significant implications in terms of clinical management and therapeutic strategy. Our primary aim was to evaluate a possible association between early detection of AF (within 90 days from the ILR implantation) and higher AF burden. Methods: This is a retrospective single-center study of 129 consecutive patients who received implantable loop recorders (ILRs) after an ESUS for detection of subclinical AF and their AF burden. Results: Mean age was 70.3 ± 10.4 years old (males: 51.9%). Atrial fibrillation was found in 40.3% of patients. Patients with AF were older, presented a higher CHAD2S2-Vasc Score and greater left atrial volume compared with patients without AF. The median AF burden was 1.2%; 59% of patients had the first AF episode within 90 days from the ILR implant while 41% experienced the first episode later than 90 days. The AF burden was significantly higher in the former group. Of note, the univariate analysis showed that only early AF detection was significantly associated with AF burden >1% (OR 20.0; 95% CI 1.68-238.6, p = 0.01). Conclusions: The early AF detection was found to be significantly associated with a higher burden of AF.
RESUMO
PURPOSE: The implantable cardioverter-defibrillator (ICD) is the therapy of choice for the prevention of sudden cardiac death. The number of elderly patients receiving ICDs is increasing. This study aimed to assess the outcome of patients according to their age at the time of implantation, and to identify variables potentially associated with patient survival. METHODS: Between June 2009 and December 2019, we retrospectively enrolled all consecutive patients in whom ICD implantation had been performed for primary or secondary prevention at our center. RESULTS: During the study period, 670 patients underwent ICD implantation. We stratified the population into four age-classes: Class 1 (23%) (pts aged less than 60 years), Class 2 (28%) (pts aged between 60 and 70 years), Class 3 (39%) (pts aged between 70 and 80 years) and Class 4 (9%) (pts aged 80 years or older). Over a median follow-up of 42 months, the rate of deaths in Class 4 was higher than in Classes 1 and 2 (log-rank test, P < 0.01), but was comparable to that in Class 3 (P = 0.407). With increasing age, we observed more complications at the time of implantation and during follow-up. On multivariate analysis, higher NYHA class, creatinine level and CHA2DS2-VASc score were identified as independent predictors of death, while age was not associated with worse prognosis. Higher body mass index, higher NYHA class and CHA2DS2-VASc score were also confirmed as independent predictors of hospitalizations or death due to any cause. CONCLUSION: This study showed good survival in ICD patients in all age-groups, including those aged ≥80 years. The CHA2DS2-VASc score seems to be a stronger predictor of death than age.

BACKGROUND: Permanent cardiac pacing is the therapy of choice for treating severe and/or symptomatic bradyarrhythmia. During the COVID-19 outbreak, it has been reported a decrease in the incidence of acute coronary syndrome, but few data are available about pacemaker implantation rates. This study aimed to analyze patients referred to our center with permanent cardiac pacing indication during the COVID-19 outbreak. METHODS: We compared the number, the characteristics and the outcomes of patients who underwent urgent pacemaker implantation between March and April 2019 (Group I) with those performed in the corresponding 2020 period (Group II). RESULTS: A total of 27 patients (Group I) were implanted in March-April 2019 and 34 patients (Group II) in the corresponding 2020 period. In both groups, about half of the patients received a dual-chamber pacemaker. No significant differences in baseline patients' characteristics were observed. The most frequent indication was advanced atrio-ventricular block with a prevalence of 78% and 62% in Group I and II, respectively. The rate of procedural complications, the in-hospital and 1-month mortality were also similar between the two groups. CONCLUSIONS: In our regional referral center, we observed a routine activity in terms of urgent pacemaker implantations for the treatment of symptomatic bradyarrhythmia during the COVID-19 outbreak.

A patient with severe pectus excavatum, dilated ischemic heart disease, and indication for defibrillator implantation for primary prevention of sudden death underwent successful ultrasound-guided serratus anterior plane block and parasternal block with intermuscular two-incision technique implantation with no complications. At follow-up, all the parameters resulted stable with excellent signal sensing.
