Impact of COVID-19 on incidence and outcomes of post-infarction mechanical complications in Europe.

Objectives: Post-acute myocardial infarction mechanical complications (post-AMI MCs) represent rare but life-threatening conditions, including free-wall rupture, ventricular septal rupture and papillary muscle rupture. During the coronavirus disease-19 (COVID-19) pandemic, an overwhelming pressure on healthcare systems led to delayed and potentially suboptimal treatments for time-dependent conditions. As AMI-related hospitalizations decreased, limited information is available whether higher rates of post-AMI MCs and related deaths occurred in this setting.

The current clinical practice for management of post-infarction ventricular septal rupture: a European survey.

Aims: Many historical and recent reports showed that post-infarction ventricular septal rupture (VSR) represents a life-threatening condition and the strategy to optimally manage it remains undefined. Therefore, disparate treatment policies among different centres with variable results are often described. We analysed data from European centres to capture the current clinical practice in VSR management.

Extracorporeal life support in mitral papillary muscle rupture: Outcome of multicenter study.

Background: Post-acute myocardial infarction papillary muscle rupture (post-AMI PMR) may present variable clinical scenarios and degree of emergency due to result of cardiogenic shock. Veno-arterial extracorporeal life support (V-A ECLS) has been proposed to improve extremely poor pre- or postoperative conditions. Information in this respect is scarce.

[ANMCO Position paper: Care pathway for advanced heart failure patients candidate for heart transplantation/ventricular assist device].

Heart failure is a complex clinical syndrome with a severe prognosis, despite therapeutic progress. The management of the advanced stages of the syndrome is particularly complex in patients who are referred to palliative care as well as in those who are candidates for cardiac replacement therapy. For the latter group, a prompt recognition of the transition to the advanced stage as well as an early referral to the centers for cardiac replacement therapy are essential elements to ensure that patients follow the most appropriate diagnostic-therapeutic pathway.

Organ Care System Heart™ in donors requiring high-risk excision of suspected neoplastic lesions.

Although Heart Transplant is still the gold standard treatment for end-stage heart failure patients, the limitation of this procedure is the discrepancy between the amount of waiting list patients and donors. Organ Care Systems, preventing the detrimental effects of cold ischemia, potentially increase donor pool. Herein we report three cases where high-risk excisions were required to clarify the nature of suspected lesions in donors.

Surgical treatment for post-infarction papillary muscle rupture: a multicentre study.

Objectives: Papillary muscle rupture (PMR) is a rare but potentially fatal complication of acute myocardial infarction. The aim of this study was to analyse the patient characteristics and early outcomes of the surgical management of post-infarction PMR from an international multicentre registry.

Methods: Patients underwent surgery for post-infarction PMR between 2001 through 2019 were retrieved from database of the CAUTION study.

Surgical Treatment of Postinfarction Ventricular Septal Rupture.

Importance: Ventricular septal rupture (VSR) is a rare but life-threatening mechanical complication of acute myocardial infarction associated with high mortality despite prompt treatment. Surgery represents the standard of care; however, only small single-center series or national registries are usually available in literature, whereas international multicenter investigations have been poorly carried out, therefore limiting the evidence on this topic.

Objectives: To assess the clinical characteristics and early outcomes for patients who received surgery for postinfarction VSR and to identify factors independently associated with mortality.

Mechanical Hemolysis Complicating Transcatheter Interventions for Valvular Heart Disease: JACC State-of-the-Art Review.

Mechanical intravascular hemolysis is frequently observed following procedures on heart valves and uncommonly observed in native valvular disease. In most cases, its severity is mild. Nevertheless, it can be clinically significant and even life threatening, requiring multiple blood transfusions and renal replacement therapy.

Percutaneous RVAD with the Protek Duo for severe right ventricular primary graft dysfunction after heart transplant.

Right ventricular primary graft dysfunction after heart transplant is a serious life-threatening condition. The severe form, refractory to maximal medical therapy, has traditionally required temporary mechanical support through veno-arterial extracorporeal membrane oxygenation or central right ventricular support. The Protek Duo is a dual lumen cannula recently introduced in the market, which allows for the institution of a percutaneous right ventricular support.

COVID-19 in Heart Transplant Recipients: A Multicenter Analysis of the Northern Italian Outbreak.

Objectives: The aim of this study was to assess the clinical course and outcomes of all heart transplant recipients affected by coronavirus disease-2019 (COVID-19) who were followed at the leading heart transplant centers of Northern Italy.

Background: The worldwide severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) pandemic has created unprecedented challenges for public health, demanding exceptional efforts for the successful management and treatment of affected patients. Heart transplant patients represent a unique cohort of chronically immunosuppressed subjects in which SARS-CoV-2 may stimulate an unpredictable clinical course of infection.

Switch from minimally invasive biventricular mechanical support to cardiopulmonary bypass during heart transplant.

An easily reproducible surgical technique to switch from percutaneous minimally invasive biventricular mechanical support to cardiopulmonary bypass during heart transplantation is illustrated. After cannulation of the distal ascending aorta with a standard arterial cannula, the ProtekDuo® cannula and the ProtekSolo® Transseptal cannula were partially retracted to reach the superior and inferior vena cava, respectively, and connected to the pump circuit for the venous drainage. With this cardiopulmonary bypass configuration, orthotopic heart transplantation was routinely performed and, at the end of the procedure, the 2 cannulas were uneventfully removed.

Long-term clinical outcome and performance of transcatheter aortic valve replacement with a self-expandable bioprosthesis.

Aims: In the last decade, transcatheter aortic valve (TAV) replacement determined a paradigm shift in the treatment of patients with severe symptomatic aortic stenosis. Data on long-term TAV performance are still limited. We sought to evaluate the clinical and haemodynamic outcomes of the CoreValve self-expandable valve up to 8-year follow-up (FU).

Sequencing of NOTCH1 gene in an Italian population with bicuspid aortic valve: Preliminary results from the GISSI OUTLIERS VAR study.

Background: Bicuspid aortic valve (BAV) formation is genetically determined, with reduced penetrance and variable expressivity. NOTCH1 is a proven candidate gene and its mutations have been found in familial and sporadic cases of BAV.

Methods: 66 BAV patients from the GISSI VAR study were genotyped for the NOTCH1 gene.

Management of cardiogenic shock in acute decompensated chronic heart failure: The ALTSHOCK phase II clinical trial.

Management of acute decompensated heart failure patients presenting with cardiogenic shock (CS) is not straightforward, as few data are available from clinical trials. Stabilization before left ventricle assist device (LVAD) or heart transplantation (HTx) is strongly advocated, as patients undergoing LVAD implant or HTx in critical status have worse outcomes. This was a multicenter phase II study with a Simon 2-stage design, including 24 consecutive patients treated with low-moderate epinephrine doses, whose refractory CS prompted implantation of intra-aortic balloon pump (IABP) which was subsequently upgraded with peripheral venoarterial extracorporeal membrane oxygenation.

HeartWare-HVAD for end-stage heart failure: a review of clinical experiences with ≥50 patients.

Despite the improvements in medical and surgical treatments, the incidence of end-stage heart failure (ESHF) continues to increase. Different mechanical systems have been adopted to support failing left ventricles. Among continuous-flow devices, the HeartWare-HVAD was the first to use a centrifugal pump rather than an axial one.

Late Echocardiographic Study of Aortic Valve and Aortic Root after Surgery for Type A Acute Aortic Dissection.

Objective: In case of concomitant aortic regurgitation (AR) valve, sparing operation is considered the first choice in selected patients. The aim of this retrospective clinical and echocardiographic study was to evaluate the long-term survival results of conservative approach and the determinants of recurrent AR.

Methods: From 2000 to 2011, fifty patients (median: 63 years and interquartile range: 53-72) underwent an aortic valve-sparing procedure for acute aortic dissection, and discharged alive.

Mitral periprosthetic leakage: contemporary results of surgical correction at a single centre.

Objectives: Mitral periprosthetic leakage (PPL) is a serious complication following valve replacement. Conflicting outcomes of surgical treatment have been reported in the presence of multiple previous cardiac operations and associated co-pathological conditions.

Methods: Sixty-five symptomatic patients (37 women, mean age 64.

Direct Transaortic TEVAR: An Alternative Option for Selected Patients With Unsuitable Peripheral Access.

Thoracic endovascular aortic repair (TEVAR) is effectively executed in patients with arch or descending aortic diseases. Peripheral access sites are preferably used as standard gates for TEVAR. Feasibility of a peripheral approach might need an intraoperative evaluation and alternative routes should have been carefully assessed.

Venoarterial Extracorporeal Membrane Oxygenation for Acute Fulminant Myocarditis in Adult Patients: A 5-Year Multi-Institutional Experience.

Background: Acute fulminant myocarditis (AFM) may represent a life-threatening event, characterized by rapidly progressive cardiac compromise that ultimately leads to refractory cardiogenic shock or cardiac arrest. Venoarterial extracorporeal membrane oxygenation (VA-ECMO) provides effective cardiocirculatory support in this circumstance, but few clinical series are available about early and long-term results. Data from a multicenter study group are reported which analyzed subjects affected by AFM and treated with VA-ECMO during a 5-year period.
