  Abstract
  
  BACKGROUND:
  As the novel SARS-CoV-2 pandemic occurred, no specific treatment was yet available. Inflammatory response secondary to viral infection might be the driver of severe diseases. We report the safety and efficacy (in terms of overall survival and hospital discharge) of the anti-IL6 tocilizumab (TCZ) in subjects with COVID-19.
  
  METHODS:
  This retrospective, single-center analysis included all the patients consecutively admitted to our Hospital with severe or critical COVID-19 who started TCZ treatment from March 13th to April 03rd, 2020. A 1:2 matching to patients not treated with TCZ was performed according to age, sex, severity of disease, P/F, Charlson Comorbidity Index and length of time between symptoms onset and hospital admittance. Descriptive statistics and non-parametric tests to compare the groups were applied. Kaplan Meier probability curves and Cox regression models for survival, hospital discharge and orotracheal intubation were used.
  
  RESULTS:
  Seventy-four patients treated with TCZ were matched with 148 matched controls. They were mainly males (81.5%), Caucasian (82.0%) and with a median age of 59 years. The majority (69.8%) showed critical stage COVID-19 disease. TCZ use was associated with a better overall survival (HR 0.499 [95% CI 0.262-0.952], p?=?0.035) compared to controls but with a longer hospital stay (HR 1.658 [95% CI 1.088-2.524], p?=?0.019) mainly due to biochemical, respiratory and infectious adverse events.
  
  DISCUSSION:
  TCZ use resulted potentially effective on COVID-19 in terms of overall survival. Caution is warranted given the potential occurrence of adverse events.
  
  FINANCIAL SUPPORT:
  Some of the tocilizumab doses used in the subjects included in this analysis were provided by the "Multicenter study on the efficacy and tolerability of tocilizumab in the treatment of patients with COVID-19 pneumonia" (EudraCT Number: 2020-001110-38) supported by the Italian National Agency for Drugs (AIFA). No specific funding support was planned for study design, data collection and analysis and manuscript writing of this paper.

  Abstract
  
  INTRODUCTION:
  No data regarding the safety of continuous-flow left ventricular assist device (CF-LVAD) implantation in patients with previous MitraClip have been reported. Thus, it remains unknown whether an initial treatment strategy with MitraClip therapy might complicate future heart failure management in patients who are also considered for CF-LVAD.
  
  METHODS:
  We retrospectively identified 6 patients (median age of 62?years; 2 women) who had been treated with MitraClip, that were eventually implanted with a CF-LVAD (all Heartware HVAD) in 3 hospitals between 2013 and 2018.
  
  RESULTS:
  Patients were treated in 4 cases with 2 clips, and in 2 cases with 1 clip. Median time from MitraClip implantation to CF-LVAD implant was 282?days (interquartile range 67 to 493), and median time on CF-LVAD support was 401?days (interquartile range 105 to 492?days). Two patients underwent a heart transplant, 3 patients died on support, and 1 is alive on support. In all cases, there was a reduction of functional mitral regurgitation without MitraClip-related complications.
  
  CONCLUSIONS:
  Based on this small case series, implantation of a CF-LVAD appears safe in patients with a previously positioned MitraClip system, at least, with 1 or 2 clips in place, with no need for additional mitral valve surgery.

  Abstract
  
  BACKGROUND:
  Previous reports have suggested that despite their dramatic presentation, patients with fulminant myocarditis (FM) might have better outcome than those with acute nonfulminant myocarditis (NFM). In this retrospective study, we report outcome and changes in left ventricular ejection fraction (LVEF) in a large cohort of patients with FM compared with patients with NFM.
  
  METHODS:
  The study population consists of 187 consecutive patients admitted between May 2001 and November 2016 with a diagnosis of acute myocarditis (onset of symptoms <1 month) of whom 55 required inotropes and/or mechanical circulatory support (FM) and the remaining 132 were hemodynamically stable (NFM). We also performed a subanalysis in 130 adult patients with acute viral myocarditis and viral prodrome within 2 weeks from the onset, which includes 34 with FM and 96 with NFM. Patients with giant-cell myocarditis, eosinophilic myocarditis, or cardiac sarcoidosis and those <15 years of age were excluded from the subanalysis.
  
  RESULTS:
  In the whole population (n=187), the rate of in-hospital death or heart transplantation was 25.5% versus 0% in FM versus NFM, respectively (<0.0001). Long-term heart transplantation-free survival at 9 years was lower in FM than NFM (64.5% versus 100%, log-rank <0.0001). Despite greater improvement in LVEF during hospitalization in FM versus NFM forms (median, 32% [interquartile range, 20%-40%] versus 3% [0%-10%], respectively; <0.0001), the proportion of patients with LVEF <55% at last follow-up was higher in FM versus NFM (29% versus 9%; relative risk, 3.32; 95% confidence interval, 1.45-7.64, =0.003). Similar results for survival and changes in LVEF in FM versus NFM were observed in the subgroup (n=130) with viral myocarditis. None of the patients with NFM and LVEF ?55% at discharge had a significant decrease in LVEF at follow-up.
  
  CONCLUSIONS:
  Patients with FM have an increased mortality and need for heart transplantation compared with those with NFM. From a functional viewpoint, patients with FM have a more severely impaired LVEF at admission that, despite steep improvement during hospitalization, remains lower than that in patients with NFM at long-term follow-up. These findings also hold true when only the viral forms are considered and are different from previous studies showing better prognosis in FM.

  Abstract
  
  OBJECTIVE:
  Transcatheter aortic valve implantation (TAVI) has been designed to treat elderly patients with severe aortic stenosis at high risk for surgery. These patients are also often affected by severe iliac-femoral arteriopathy, rendering the trans-femoral approach unusable. We report our experience with the direct-aortic approach to treat these patients.
  
  METHODS:
  From May 2008 to November 2013 two hundred and thirty-two patients (131 female, 56%) with severe symptomatic aortic stenosis and no reasonable surgical option due to excessive risk were evaluated for TAVI at our department. Of these patients, 202 were deemed eligible for TAVI. Of this group, 50 underwent CoreValve implantation by the direct aortic approach through a right anterior mini-thoracotmy (28 female, 56%), mean age 81.2±6.9. A combined team of cardiologists, cardiac surgeons with expertise in hybrid procedures, and anesthetists performed all the procedures.
  
  RESULTS:
  Twenty-eight (56%) patients were female and 11 (22%) were redo at TAVI. We used a 23-mm CoreValve Evolute in 3 patients (6%), and the most used valve size was the 29mm in 46% of patients. Mean hemodynamic trans-aortic gradient was less than 5mmHg. The paravalvular regurgitation was ? grade 1 in 46 patients as assessed by peri-procedural transesophageal echocardiography (TEE). Seven patients (7/43, 16%) required a permanent pacemaker implantation; 30-day mortality was 6% (3 patients). Seven patients (14.8%) died during follow-up. Actuarial survival at 2years is 84.7±5.3%.
  
  CONCLUSIONS:
  Transcatheter aortic valve implantation with the direct aortic approach is safe and feasible, offering a new attractive option to treat selected high-risk patients with severe aortic stenosis and peripheral vasculopathy, including those requiring a re-do procedure.

  Abstract
  
  Transcatheter aortic valve implantation has been introduced as a treatment modality applied to high-risk surgery patients with severe symptomatic aortic stenosis, and it has been demonstrated to be an efficient and safe treatment option. Litzler and colleagues reported a case of a bailout of a transcatheter aortic valve implantation because of severe paravalvular leaks, using a 23-mm Edwards-SAPIEN Valve (Edwards Lifesciences, Irvine, CA), with conversion to conventional surgical aortic valve replacement. The authors reported an easy valve removal despite the impaction of the stent in the cusps of the native valve. Thyregod and colleagues reported a surgical valve replacement in a patient with a dysfunctional CoreValve self-expanding aortic valve bioprosthesis 4 months after implantation.
