Interplay between gender and pollution on the prognosis of resuscitated out-of-hospital cardiac arrest.

Background: Differences between men and women in prognosis after sudden pre-hospital out-of-hospital cardiac arrest (OHCA) have been described in many studies, but the interplay between gender and pollution have not been characterized in detail. We aimed at appraising the interplay between gender and pollution on the prognosis of OHCA.

Methods: Details on patients with OHCA in whom return of spontaneous circulation was obtained and transferred to a large teaching hospital were obtained from the medical charts of the ambulance service and the Polish National Health Fund.

Progression of the ascending aorta diameter after surgical or transcatheter bicuspid aortic valve replacement.

Objectives: Ascending aorta (AA) dilatation in patients with bicuspid aortic valve (AV) is related both to genetic and haemodynamic factors. The aim of this study is to compare late progression of AA dilatation in bicuspid AV patients undergoing surgical aortic valve replacement (SAVR) versus transcatheter aortic valve implantation (TAVI).

Methods: Data of 189 consecutive patients who underwent AV replacement for severe bicuspid AV stenosis were prospectively collected.

Long-Term Outcomes of Bioprosthetic Valves in the Mitral Position: A Pooled Meta-Analysis of Reconstructed Time-to-Event Individual Patient Data.

Bioprosthetic mitral valve replacement (bMVR) use is increasing; however, data regarding long-term durability are lacking. We sought to perform a reconstructed individual patient data meta-analysis from published Kaplan-Meier curves to ascertain survival, freedom from valve degeneration, and reoperation in studies published since 2010. We explored the effects of age and valve type (bovine pericardial or porcine valve) on outcomes.

Outcomes of Minimally Invasive Aortic Valve Replacement in Obese Patients: A Propensity-Matched Study.

Introduction: Obese patients are at risk of complications after cardiac surgery. The aim of this study is to investigate safety and efficacy of a minimally invasive approach via upper sternotomy in this setting.

Methods: We retrospectively reviewed 203 obese patients who underwent isolated, elective aortic valve replacement between January 2014 and January 2023 - 106 with minimally invasive aortic valve replacement (MIAVR) and 97 with conventional aortic valve replacement (CAVR).

The multidisciplinary Heart Team approach for patients with cardiovascular disease: a step towards personalized medicine.

Aims: Despite general agreement on the benefits of the Heart Team approach for patients with cardiac diseases, few data are available on its real impact on the decision-making process. The aim of the study is to define the evolution over time of the level of agreement with the systematic discussion of patients in the Heart Team and to evaluate the adherence to the Heart Team recommendations and the impact of the Heart Team on the clinical outcome of the patients.

Methods: In 2015--2016, an experienced cardiac surgeon and a cardiologist independently reviewed clinical data of a series of 100 patients (Group 1, G1) and subsequently for each patient recommended treatment (surgical, percutaneous, hybrid or medical therapy) or further diagnostic investigations.

Comparison of De-Kay repair versus De Vega suture for functional tricuspid regurgitation: a preliminary experience.

Background: In patients undergoing mitral valve surgery, restrictive suture annuloplasty (De Vega) for less-than-severe functional tricuspid regurgitation has been proven to be safe and effective. The aim of this study is to determine whether the adjunct of the plication of the posterior tricuspid leaflet with the same running suture (bicuspidized De Vega or "De Kay") is equally safe and effective.

Methods: Single center, retrospective study on patients submitted to suture repair of the tricuspid valve during mitral valve surgery, with either conventional or De Kay, between January 2014 and December 2020.

The metaverse in medicine.

The metaverse is an alternative digital world, accessed by means of dedicated audiovisual devices. In this parallel world, various forms of artificial intelligence meet, including individuals in the form of digital copies of real people (avatars), able to interact socially. Metaverse in medicine may be used in many different ways.

Two innovative aortic bioprostheses evaluated in the real-world setting. First results from a two-center study.

Background: The increasing use of biological substitutes for surgical aortic valve replacement (AVR), has led to the development of new bioprostheses with improved hemodynamics and expected durability.

Methods: In this observational retrospective two-center cohort study, two innovative bioprostheses, INSPIRIS Resilia and AVALUS were analyzed. We analyzed early and 2.

The Sodium-Glucose Co-Transporter-2 (SGLT2) Inhibitors Reduce Platelet Activation and Thrombus Formation by Lowering NOX2-Related Oxidative Stress: A Pilot Study.

Sodium−glucose co-transporter-2 inhibitors or gliflozins, the newest anti-hyperglycemic class, induce cardioprotective benefits in patients with type 2 diabetes (T2D). As platelet activation and oxidative stress play a key role in atherothrombotic-related complications, we hypothesized that gliflozins might modulate oxidative stress, platelet activation and thrombus formation. We performed an interventional open-label single-arm before-after study in 32 T2D patients on top of their ongoing metformin therapy.

Natural Activators of Autophagy Increase Maximal Walking Distance and Reduce Oxidative Stress in Patients with Peripheral Artery Disease: A Pilot Study.

Trehalose, spermidine, nicotinamide, and polyphenols have been shown to display pro-autophagic and antioxidant properties, eventually reducing cardiovascular and ischemic complications. This study aimed to investigate whether a mixture of these components improves maximal walking distance (MWD) in peripheral artery disease (PAD) patients. Nitrite/nitrate (NOx), endothelin-1, sNOX2-dp, H2O2 production, H2O2 break-down activity (HBA), ATG5 and P62 levels, flow-mediated dilation (FMD), and MWD were evaluated in 20 PAD patients randomly allocated to 10.

Evaluation of an Innovative Device for Mitral Valve Regurgitation: Experimental Acute In Vivo Results.

Currently, mitral prosthetic rings are intended only to reshape the annulus. We present in vivo results of an innovative device characterized by an intraventricular segment designed to enable artificial chordae implantation and simplify leaflets and subvalvular apparatus correction. Eight sheep were employed.

Usability, performance and safety of a new device for degenerative mitral regurgitation: in vivo chronic evaluation.

Objectives: This study aimed to evaluate the usability, performance and safety of an innovative mitral valve device in the chronic setting characterized by an intraventricular bridge, which enables artificial chordae anchoring and/or direct posterior leaflet fixation.

Methods: Ten female sheep were employed and underwent device implantation. Any interference of the device with leaflet motion, ease of device use, correct chordae length estimation and implantation were evaluated.

Bleeding Complications in Patients With Perioperative COVID-19 Infection Undergoing Cardiac Surgery: A Single-Center Matched Case-Control Study.

Objective: Previous studies reported a poor outcome in patients with coronavirus 2019 (COVID-19) undergoing cardiac surgery. Complications most frequently described were respiratory failure, renal failure, and thromboembolic events. In their recent experience, the authors observed a very high incidence of bleeding complications.
