Abstract Aims The recent coronavirus disease 19 (COVID‐19) pandemic outbreak forced the adoption of restraint measures, which modified the hospital admission patterns for several diseases. The aim of the study is to investigate the rate of hospital admissions for heart failure (HF) during the early days of the COVID‐19 outbreak in Italy, compared with a corresponding period during the previous year and an earlier period during the same year. Methods and results We performed a retrospective analysis on HF admissions number at eight hospitals in Italy throughout the study period (21 February to 31 March 2020), compared with an inter‐year period (21 February to 31 March 2019) and an intra‐year period (1 January to 20 February 2020). The primary outcome was the overall rate of hospital admissions for HF. A total of 505 HF patients were included in this survey: 112 during the case period, 201 during intra‐year period, and 192 during inter‐year period. The mean admission rate during the case period was 2.80 admissions per day, significantly lower compared with intra‐year period (3.94 admissions per day; incidence rate ratio, 0.71; 95% confidence interval [CI], 0.56–0.89; P = 0.0037), or with inter‐year (4.92 admissions per day; incidence rate ratio, 0.57; 95% confidence interval, 0.45–0.72; P

Background We evaluated long‐term outcome of isolation of pulmonary veins, left atrial posterior wall, and superior vena cava, including time to recurrence and prevalent triggering foci at repeat ablation in patients with paroxysmal atrial fibrillation with or without cardiovascular comorbidities. Methods and Results A total of 1633 consecutive patients with paroxysmal atrial fibrillation that were arrhythmia‐free for 2 years following the index ablation were classified into: group 1 (without comorbidities); n=692 and group 2 (with comorbidities); n=941. We excluded patients with documented ablation of areas other than pulmonary veins, the left atrial posterior wall, and the superior vena cava at the index procedure. At 10 years after an average of 1.2 procedures, 215 (31%) and 480 (51%) patients had recurrence with median time to recurrence being 7.4 (interquartile interval [IQI] 4.3–8.5) and 5.6 (IQI 3.8–8.3) years in group 1 and 2, respectively. A total of 201 (93.5%) and 456 (95%) patients from group 1 and 2 underwent redo ablation; 147/201 and 414/456 received left atrial appendage and coronary sinus isolation and 54/201 and 42/456 had left atrial lines and flutter ablation. At 2 years after the redo, 134 (91.1%) and 391 (94.4%) patients from group 1 and 2 receiving left atrial appendage/coronary sinus isolation remained arrhythmia‐free whereas sinus rhythm was maintained in 4 (7.4%) and 3 (7.1%) patients in respective groups undergoing empirical lines and flutter ablation (P

Background Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) utilizes the angiotensin‐converting enzyme‐2 (ACE‐2) receptor to enter human cells. Angiotensin‐converting enzyme inhibitors (ACEI) and angiotensin II receptor antagonists (ARB) are associated with ACE‐2 upregulation. We hypothesized that antecedent use of ACEI/ARB may be associated with mortality in coronavirus disease 2019 (COVID‐19). Methods and Results We used the Coracle registry, which contains data of patients hospitalized with COVID‐19 in 4 regions of Italy, and restricted analyses to those ≥50 years of age. The primary outcome was in‐hospital mortality. Among these 781 patients, 133 (17.0%) used an ARB and 171 (21.9%) used an ACEI. While neither sex nor smoking status differed by user groups, patients on ACEI/ARB were older and more likely to have hypertension, diabetes mellitus, and congestive heart failure. The overall mortality rate was 15.1% (118/781) and increased with age (PTrend

Abstract  We report the case of a 50 year-old woman referred for extraction of an infected biventricular implantable cardioverter defibrillator (ICD) who underwent device and leads extraction. Due to adhesions at the level of the subclavian–innominate vein angle, manual traction with locking stylet was ineffective. A new mechanical sheath provided with a stainless steel bladed tip, the Evolution™ Mechanical Dilator Sheath (Cook Medical), was successfully used to complete lead extraction. As far as we know, this is the first report on the use of this new tool; its safety should be ascertained by increasing the number of cases but its simple use and its low cost make the Evolution™ Mechanical Dilator Sheath a new interesting tool that can be added to the instruments available for lead extraction.

Abstract Background  Atrial fibrillation (AF) drivers outside pulmonary veins (PV) may account for failure after PV isolation. The aim of this study was to characterize pre-existent areas of complex fractionated atrial electrograms (CFAEs) recorded in right atrium (RA) and in coronary sinus (CS) during catheter-based PV isolation and to assess their relation to outcome. Methods and results  With a tricuspid annulus and CS mapping, CFAEs were retrospectively identified in consecutive patients who underwent PV isolation. Of 224 patients, 161 were found to have CFAEs (81%). No clinical variable was found to be predictive of CFAEs presence. By Kaplan–Meier analysis, following a median follow-up of 23.7 months after a single ablation procedure, 62.8% of patients in the CFAEs() group and 85.4% of those in the CFAEs(−) group were free from recurrent atrial tachyarrhythmias (p = 0.013). Multivariable Cox regression analysis showed that CFAEs evidence was an independent predictor of recurrence (p = 0.007). Conclusions  Pre-existent CFAEs, that can be easily identified in RA and CS during PV isolation, are a powerful independent predictor for AF recurrence. This finding may be helpful for refining AF ablation strategies. [ABSTRACT FROM AUTHOR]
