Emergent Conversion to Open Heart Surgery during Transcatheter Aortic Valve Implantation: The Presence of a Rescue Team Improves Outcomes.

Objective: Transcatheter aortic valve implant (TAVI) is the gold standard for the high-surgical-risk group of patients with aortic valve disease and it is an alternative to surgery in patients at intermediate risk. Lethal complications can occur, and many of these are manageable only with emergent conversion to open heart surgery. We retrospectively evaluate the outcome of all patients undergoing TAVI in our departments and the impact of a complete cardiac rescue team to reduce 30-day mortality.

Mid-term results of endoscopic mitral valve repair and insights in surgical techniques for isolated posterior prolapse.

Background: The adoption of minimally invasive techniques to perform mitral valve repair surgery is increasing. This is enhanced by the compelling evidence of satisfactory short-term results and lower major morbidity. We analyzed mid-term follow-up results of our experience, and further compared two techniques: isolated leaflet resection and neochord implantation for posterior leaflet prolapse.

Bilateral mini-thoracotomy for combined minimally invasive direct coronary artery bypass and mitral valve repair.

Consistent evidence recognizes minimally invasive valve surgery as the top-tier surgical approach for heart valve pathology. Conversely, the overall adoption of minimally invasive coronary surgery remains low. Notwithstanding, excellent clinical outcomes have been recently reported, further consolidating a technique that addresses major concerns associated with the traditional approach for the most frequently performed cardiac operation, including sternal dehiscence (i.

Comparison of a full sternotomy with a minimally invasive approach for concomitant mitral and tricuspid valve surgery.

Objectives: The need for concomitant tricuspid surgery in patients who need mitral valve surgery casts doubt on its feasibility via a minimally invasive approach. Our goal was to evaluate the short-term outcomes of patients undergoing concomitant mitral and tricuspid valve surgery either with a standard full sternotomy (full-MTS) or a minimally invasive approach (mini-MTS).

Methods: The outcomes of patients who had combined mitral and tricuspid valve surgery in 11 centres were retrospectively evaluated.

High-Sensitivity Troponin I after Cardiac Surgery and 30-Day Mortality.

Background: Consensus recommendations regarding the threshold levels of cardiac troponin elevations for the definition of perioperative myocardial infarction and clinically important periprocedural myocardial injury in patients undergoing cardiac surgery range widely (from >10 times to ≥70 times the upper reference limit for the assay). Limited evidence is available to support these recommendations.

Methods: We undertook an international prospective cohort study involving patients 18 years of age or older who underwent cardiac surgery.

Mechanical circulatory support and intravascular lithotripsy in high-risk patients undergoing percutaneous coronary intervention and transcatheter aortic valve replacement: a case series.

Background: Patients undergoing transcatheter aortic valve replacement (TAVR) usually have multiple comorbidities, such as severely impaired left ventricular function (LVF) and heavily calcified coronary lesions. When they undergo pre-TAVR high-risk percutaneous coronary interventions (HR-PCIs) for severely calcified left main (LM) lesions, potential life-threatening intra-procedural complications associated with the different techniques available to treat calcified lesions can arise. In this setting, mechanical circulatory support proves its usefulness.

Prognostic value of SARS-CoV-2 on patients undergoing cardiac surgery.

Objective: To analyze Italian Cardiac Surgery experience during the pandemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) identifying risk factors for overall mortality according to coronavirus disease 2019 (COVID-19) status.

Methods: From February 20 to May 31, 2020, 1354 consecutive adult patients underwent cardiac surgery at 22 Italian Centers; 589 (43.5%), patients came from the red zone.

Sutureless versus transcatheter aortic valve replacement: A multicenter analysis of "real-world" data.

Background: Recent data suggested that transcatheter aortic valve replacement (TAVR) may be indicated also for low-risk patients. However, robust evidence is still lacking, particularly regarding valve performance at follow-up that confers a limitation to its use in young patients. Moreover, a literature gap exists in terms of 'real-world' data analysis.

Minimally invasive tricuspid valve surgery without caval occlusion: Short and midterm results.

Objective: The use of minimally invasive or transcatheter interventions rather than standard full sternotomy operations to treat tricuspid valve (TV) disease is increasing. The debate however is still open regarding venous drainage management during cardiopulmonary bypass (CPB) and wheatear or not superior and inferior vena cava should be occluded during the opening of the right atrium to avoid air entrance in the venous line. The aim of the present study is to report operative outcomes and midterm follow-up results of minimally invasive TV surgery performed without caval occlusion.

Right ventricular assessment can improve prognostic value of Euroscore II.

Background: The aim of this multicenter prospective study was to evaluate the prognostic weight of preoperative right ventricular assessment on early mortality in cardiac surgery.

Methods: This is a multicenter prospective observational study performed by the Italian Group of Research for Outcome in Cardiac Surgery (GIROC) including 11 centers. From October 2017 to March 2019, out of 923 patients undergoing cardiac surgery, 28 patients with some missing data were excluded and 895 patients were enrolled in the study right ventricular dilatation was defined as a basal end-diastolic diameter >42 mm.

Aortic valve endocarditis complicated by proximal false aneurysm.

Background: Aortic valve endocarditis remains a life-threatening condition, especially in cases of periannular complications. Aorto-ventricular discontinuity associated with proximal false aneurysm represents a severe picture caused by extensive tissue disruption and is usually associated with prosthetic valve infection. Complex surgical repair is required in these cases and continues to be associated with high mortality and morbidity rates.

Current trends in mitral valve surgery: A multicenter national comparison between full-sternotomy and minimally-invasive approach.

Background: Mitral valve surgery (MVS) is evolving. Compared to standard sternotomy (S-MVS), minimally invasive method (Mini-MVS) has been increasingly adopted in the last years with encouraging results for both repairs and replacements. We evaluated trends of surgical approaches and operative outcomes in a multicenter study involving 10 cardiac surgical centers in Italy.

Full sternotomy and minimal access approaches for surgical aortic valve replacement: a multicentre propensity-matched study.

Objectives: Surgical aortic valve replacement (AVR) can be performed via a full sternotomy or a minimal access approach (mini-AVR). Despite long-term experience with the procedure, mini-AVR is not routinely adopted. Our goal was to compare contemporary outcomes of mini-AVR and conventional AVR in a large multi-institutional national cohort.

Durability of Mitral Valve Bioprostheses: A Meta-Analysis of Long-Term Follow-up Studies.

Background: Porcine and pericardial valves exhibited similar freedom from structural valve deterioration after aortic valve replacement. Limited data exist regarding their durability at long-term follow-up in the mitral position.

Methods: A literature search was performed through online databases.

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].

Prevalence and Clinical Impact of Systemic Inflammatory Reaction After Cardiac Surgery.

Objectives: Cardiac surgery induces a systemic inflammatory reaction that has been associated with postoperative mortality and morbidity. Many studies have characterized this reaction through laboratory biomarkers while clinical studies generally are lacking. This study aimed to assess the incidence of postoperative systemic inflammation after cardiac surgery, and the association of postoperative systemic inflammation with preoperative patients' characteristics and postoperative outcomes.

External aortic cross-clamping and endoaortic balloon occlusion in minimally invasive mitral valve surgery.

Background: Minimally invasive cardiac surgery has increasingly been used for patients with valvular pathology. Two techniques of aortic occlusion are utilized with this technique: transthoracic aortic clamp (TTC) and endoaortic balloon occlusion (EAO). Both possibilities present peculiar advantages and limitations whose current evidence is based on few observational studies.

GLP-1 Receptor Activation Inhibits Palmitate-Induced Apoptosis via Ceramide in Human Cardiac Progenitor Cells.

Context: Increased apoptosis of cardiomyocytes and cardiac progenitor cells (CPCs) in response to saturated fatty acids (SFAs) can lead to myocardial damage and dysfunction. Ceramides mediate lipotoxicity-induced apoptosis. Glucagonlike peptide-1 receptor (GLP1R) agonists exert beneficial effects on cardiac cells in experimental models.

The Effects of Steroids on Coagulation Dysfunction Induced by Cardiopulmonary Bypass: A Steroids in Cardiac Surgery (SIRS) Trial Substudy.

Cardiopulmonary bypass (CPB) surgery, despite heparin administration, elicits activation of coagulation system resulting in coagulopathy. Anti-inflammatory effects of steroid treatment have been demonstrated, but its effects on coagulation system are unknown. The primary objective of this study is to assess the effects of methylprednisolone on coagulation function by evaluating thrombin generation, fibrinolysis, and platelet activation in high-risk patients undergoing cardiac surgery with CPB.

A predictive model for early mortality after surgical treatment of heart valve or prosthesis infective endocarditis. The EndoSCORE.

Background: The aim of this large retrospective study was to provide a logistic risk model along an additive score to predict early mortality after surgical treatment of patients with heart valve or prosthesis infective endocarditis (IE).

Methods: From 2000 to 2015, 2715 patients with native valve endocarditis (NVE) or prosthesis valve endocarditis (PVE) were operated on in 26 Italian Cardiac Surgery Centers. The relationship between early mortality and covariates was evaluated with logistic mixed effect models.
