Distinctive phenogroup to differentiate diagnosis of cardiac myxoma vs cardiovascular disease examining blood-based circulating cell biomarkers.

Cardiac myxoma (CM) is a potentially life-threatening disease because frequently asymptomatic or debuts with aspecific manifestations. Definitive diagnosis is established by histopathological assessment including tumor and endothelial cell markers. To derive a specific panel of circulating cells antigenically detectable, pre-surgery peripheral blood samples of CM patients were analyzed.

Massive Thrombosis of Mitral Bioprosthesis Due to SARS-CoV-2 Infection.

Thromboembolic events have been reported as frequent and fearsome complications in patients affected by SARS-CoV-2 infection. Patients undergoing cardiac valve replacement exhibit an increased risk of valve thrombosis, even with prosthetic biological valves, and especially in the first period after surgery. The management of these patients is challenging and requires prompt interventions.

Genetic screening in heritable thoracic aortic disease-rationale, potentials and pitfalls.

Thoracic aortic aneurysms are silent yet deadly clinical entities which may elude detection until an acutely life-threatening aortic dissection or rupture occurs. Approximately 20% of patients with thoracic aortic aneurysms or dissection have a positive family history, indicating a strong genetic component to the aetiology. Genetic screening in such hereditary thoracic aortic disease (HTAD) may thus be beneficial in detecting causative genetic mutations in affected patients, identifying asymptomatic family members who may be at risk, and in guiding the optimal timing of preventative surgery in those with confirmed genetic aortopathy.

Micro-Invasive 3D Endoscopic Mitral Valve Surgery.

Since its introduction in 1995, minimally invasive mitral valve surgery (MIMVS) has been shown to be a valid alternative to conventional sternotomy and several studies have reported excellent clinical outcomes. While MIMVS is now a commonly performed procedure, it is still difficult to standardize. We proprose here a "road to safer surgery", and offer some tips and tricks that could be useful in its learning and performance, and may help surgeons minimize the risk of major complications.

Gender and the Outcome of Postcardiotomy Veno-arterial Extracorporeal Membrane Oxygenation.

Objective: There is a paucity of sex-specific data on patients' postcardiotomy venoarterial extracorporeal membrane oxygenation (VA-ECMO). The present study sought to assess this issue in a multicenter study.

Design: Retrospective, propensity score-matched analysis of an international registry.

Neurological Complications in High-Risk Patients Undergoing Coronary Artery Bypass Surgery.

Background: Coronary artery bypass grafting (CABG) without cardiopulmonary bypass and minimal or no aortic manipulation may be associated with a lower risk of neurological complications. We investigated this issue in patients with a high risk of perioperative stroke.

Methods: Data on 7352 patients who underwent isolated CABG from January 2015 to May 2017 were included in the multicenter study E-CABG (European Coronary Artery Bypass Grafting) registry.

Clinical and Hemodynamic Outcomes of Rapid-Deployment Aortic Bioprostheses.

Aim of this retrospective, multicenter study was to evaluate early and mid-term clinical and hemodynamic results of patients who underwent surgical aortic valve replacement (SAVR) with Intuity rapid-deployment bioprostheses (RDB) (Edwards Lifesciences, Irvine, CA). We analyzed data from the Italian Registry of Intuity Valve (INTU-ITA registry) that is a national, real-world and independent from the industry registry. Preoperative variables were defined according to EuroSCORE and postoperative outcomes according to Valve Academic Research Consortium (VARC).

Outcome of Repeat Venoarterial Extracorporeal Membrane Oxygenation in Postcardiotomy Cardiogenic Shock.

Objective: Data on patients requiring a second run of venoarterial extracorporeal membrane oxygenation (VA-ECMO) support in patients affected by postcardiotomy cardiogenic shock (PCS) are very limited. The authors aimed to investigate the effect of a second run of VA-ECMO on PCS patient survival.

Design: Retrospective analysis of an international registry.

Duration of Venoarterial Extracorporeal Membrane Oxygenation and Mortality in Postcardiotomy Cardiogenic Shock.

Objective: The optimal duration of venoarterial extracorporeal membrane oxygenation (VA-ECMO) in patients affected by postcardiotomy cardiogenic shock (PCS) remains controversial. The present study was conducted to investigate the effect of VA-ECMO duration on hospital outcomes.

Design: Retrospective analysis of an international registry.

Relation of Prolonged Pacemaker Dependency After Cardiac Surgery to Mortality.

Permanent pacemaker implantation (PPI) represents a rare complication after cardiac surgery, with no uniform agreement on timing and no information on follow-up. A multicenter retrospective study was designed to assess pacemaker dependency (PMD) and long-term mortality after cardiac surgery procedures. Between 2004 and 2016, PPI-patients from 18 centers were followed.

Minimally Invasive vs Conventional Aortic Valve Replacement With Rapid-Deployment Bioprostheses.

Background: The aim of this multicenter retrospective study was to compare early and midterm clinical and hemodynamic results of aortic valve replacement with rapid-deployment bioprostheses performed through conventional full-sternotomy vs mini-sternotomy.

Methods: Data from the Italian multicenter registry of aortic valve replacement with rapid-deployment bioprostheses (INTU-ITA registry) were analyzed. Patients were divided into 2 groups: full sternotomy (FS) and ministernotomy (MS).

Hospital Volume and Outcome after Bilateral Internal Mammary Artery Grafting.

Background: Bilateral internal mammary artery (BIMA) grafting largely is underutilized in patients undergoing coronary artery bypass grafting (CABG), partly because of the perceived increased complexity of the procedure.

Aims: In this study, we evaluated whether BIMA grafting can safely be performed also in centers, where this revascularization strategy infrequently is adopted.

Methods: Out of 6,783 patients from the prospective multicenter E-CABG study, who underwent isolated non- emergent CABG from January 2015 to December 2016, 2,457 underwent BIMA grafting and their outcome was evaluated in this analysis.

Failure to achieve a satisfactory cardiac outcome after isolated coronary surgery in low-risk patients.

Objectives: This study aims to investigate the incidence and determinants of major early adverse events in low-risk patients undergoing isolated coronary artery bypass grafting (CABG).

Methods: The multicentre E-CABG registry included 7352 consecutive patients who underwent isolated CABG from January 2015 to December 2016. Patients with an European System for Cardiac Operative Risk Evaluation (EuroSCORE) II of <2% and without any major comorbidity were the subjects of the present analysis.

Surgery for Bentall endocarditis: short- and midterm outcomes from a multicentre registry.

Objectives: Endocarditis after the Bentall procedure is a severe disease often complicated by a pseudoaneurysm or mediastinitis. Reoperation is challenging but conservative therapy is not effective. The aim of this study was to assess short- and midterm outcomes of patients reoperated on for Bentall-related endocarditis.

Venoarterial Extracorporeal Membrane Oxygenation After Surgical Repair of Type A Aortic Dissection.

Venoarterial (VA) extracorporeal membrane oxygenation (ECMO) support for postcardiotomy cardiogenic shock (PCS) in patients undergoing surgery for acute type A aortic dissection (TAAD) is controversial and the available evidence is confined to limited case series. We aimed to evaluate the impact of this salvage therapy in this patient population. Between January 2010 and March 2018, all TAAD patients receiving VA-ECMO for PCS were retrieved from the PC-ECMO registry.

Preoperative risk stratification of deep sternal wound infection after coronary surgery.

Objective: To develop a risk score for deep sternal wound infection (DSWI) after isolated coronary artery bypass grafting (CABG).

Design: Multicenter, prospective study.

Setting: Tertiary-care referral hospitals.

Surgical aortic valve replacement with new-generation bioprostheses: Sutureless versus rapid-deployment.

Objectives: The aim of this retrospective multicenter study was to compare early clinical and hemodynamic outcomes of Perceval-S sutureless (Livanova, London, United Kingdom) and Intuity rapid-deployment (Edwards Lifesciences, Irvine, Calif) bioprostheses.

Methods: Data from patients who underwent isolated or combined aortic valve replacement with Perceval-S and with Intuity bioprostheses at 18 cardiac surgical institutions were analyzed. Propensity matching was performed to identify similar patient cohorts.

Perspective. Reoperative Bentall: choice of conduits.

The Bentall procedure represents the gold standard in the treatment of patients requiring aortic root replacement. The most common indications for redo Bentall are structural degeneration or graft infection. Redo aortic root replacement can be performed with low perioperative morbidity and death.

Surgical treatment of isolated tricuspid valve infective endocarditis: 25-year results from a multicenter registry.

Background: To assess early and late mortality in patients with isolated acute tricuspid valve infective endocarditis (TVIE) using data from a multicenter registry.

Methods: From 1983 to 2018, isolated acute TVIE was surgically treated in 157 (3.8%) patients [mean age 47 ± 16 years (range 15-86 years), 25% females].

Identification of mesothelial cells in intraoperative blood salvage.

Intraoperative auto-transfusion with the use of cell saver systems is routinely used to reduce the rate of packed red blood transfusion in major surgery. Nevertheless some concerns have been raised on possible risks of coagulation disorders. The aim of the study was to analyze the blood processed by the cell saver, ready to be re-infused to the patient, in order to individuate unexpected cellular components, that can favor coagulopathy.
