Article Synopsis
  • This text describes a groundbreaking case where a unique combination of surgical and percutaneous techniques was used to treat a patient with multiple cardiac issues.
  • The procedure involved several complex interventions, including removing a transvenous lead, repairing the tricuspid valve, and placing both a leadless pacemaker and an implantable cardioverter-defibrillator.
  • These interventions were prompted by serious health challenges faced by the patient, such as active endocarditis, congenital complete AV block, and the need to prevent harmful ventricular arrhythmias.

The proliferation of transcatheter aortic valve implantation has alerted clinicians to a specific type of prosthetic degeneration represented by thrombosis. The pathogenesis of this clinical or subclinical phenomenon, which can occur in up to 15% of both surgical and percutaneous procedures, is poorly understood, as is its potential impact on patient prognosis and long-term bioprosthesis durability. Based on this lack of knowledge about the real meaning and importance of bioprosthetic valve thrombosis, the aim of the present review is to draw the clinicians' attention to its existence, starting from the description of predisposing factors that may require a closer follow-up in such categories of patients, to an in-depth overview of all available imaging modalities with their respective pros and cons.

  • In cardiogenic shock, short-term mechanical assist devices like Extra Corporeal Membrane Oxygenators help stabilize patients before considering long-term solutions.
  • For long-term support in cases of persistent biventricular dysfunction, options are limited to devices like the Syncardia Total Artificial Heart and the Berlin Heart EXCOR, which is not approved for adults in the U.S.
  • While strategies such as using two Left Ventricular Assist Devices are common, they remain off-label, and overall survival rates are around 70%, indicating significant complications and reduced quality of life for patients.

Article Synopsis
  • The study aimed to assess the outcomes of isolated coronary artery bypass grafting (CABG) in patients with or without revascularization of the occluded right coronary artery (RCA).
  • Based on a large European registry, the analysis included 724 patients with RCA occlusion, revealing that one-third did not undergo revascularization, showing variability among medical centers.
  • Results indicated that patients without RCA revascularization had a higher 5-year all-cause mortality rate (17.7%) and an increased risk of major adverse cardiovascular and cerebrovascular events (MACCE) compared to those who had the procedure (24.7% vs. 15.7%).

Redo surgeries are becoming more common because of an increased rate of bioprosthesis implantation. We performed a retrospective study on patients who underwent redo replacement of an aortic and/or mitral bioprosthesis between 2005 and 2018 to evaluate intra-hospital mortality and morbidity. Univariate analysis was performed on the propensity score variables to determine predictors of mortality.

The present explorative study aims to analyze the profiles of students seeking help in the two areas (emotion/relation or learning areas) of a psychological counseling service for students at the University of Genoa to better understand their request for support in pre- and post-pandemic periods. A total of 229 university students seeking for help from November 2018 to December 2021 completed a psychological battery investigating emotion regulation difficulties and pathological domains of personality (students taken in charge by the emotion/relation area) or motivation issues and anxiety and resilience levels (students taken in charge by the learning area). Regarding the emotion/relation area, results show that problems in emotion dysregulation, and especially in regulating positive emotions, are associated to several pathological domains of personality, such as Psychoticism, Antagonism, Disinhibition, Detachment, and Negative Affectivity.

During calcific aortic valve stenosis (CAVS) progression, oxidative stress and endothelial dysfunction mark the initial pathogenic steps with a parallel dysregulation of the antioxidant systems. Here, we tested whether oxidation-induced protein S-glutathionylation (P-SSG) accounts for a phenotypic switch in human aortic valvular tissue, eventually leading to calcium deposition. Next, we tested whether countering this reactive oxygen species (ROS) surge would prevent these perturbations.

The Commando procedure is challenging, and aims to replace the mitral valve, the aortic valve and the aortic mitral curtain, when the latter is severely affected by pathological processes (such as infective endocarditis or massive calcification). Given the high complexity, it is seldomly performed. We aim to review the literature on early (hospitalization and up to 30 days) and long-term (at least 3 years of follow-up) results.

Patients with mitral valve prolapse (MVP), undergoing early surgery for severe regurgitation, are usually characterized by a low degree of right chambers' remodeling. In this selected population, the mechanisms leading to tricuspid annular (TA) dilatation (TAD) are not well understood. In this setting, we aimed to evaluate, using three-dimensional echocardiography (3DE), how right chambers affect TA size and might contribute to functional tricuspid regurgitation (FTR) progression.

Preservation of right ventricle vascularization that is dependent on left coronary network collateral development is essential during left ventricular assist device implantation to avoid postoperative right heart failure. Our technique was performed on a patient who underwent implantation as a bridge to transplantation; the technique is characterized by providing a moderate lateral and inferior displacement of the inflow cannula position, which achieves both the objectives of respecting the apical course of a left anterior descending coronary artery supplying an occluded right coronary and of maintaining a sufficient orientation degree toward the plane of the mitral valve for correct left ventricular unloading.

Mitral valve prolapse (MVP) associated with severe mitral regurgitation is a debilitating disease with no pharmacological therapies available. MicroRNAs (miRNA) represent an emerging class of circulating biomarkers that have never been evaluated in MVP human plasma. Our aim was to identify a possible miRNA signature that is able to discriminate MVP patients from healthy subjects (CTRL) and to shed light on the putative altered molecular pathways in MVP.

Aims: Patients with coronary heart disease (CHD) are at very high risk of recurrent events. A strategy to reduce excess risk might be to deliver structured secondary prevention programmes, but their efficacy has been mostly evaluated in the short term and in experimental settings. This is a retrospective case-control study aimed at assessing, in the real world, the efficacy of a secondary prevention programme in reducing long-term coronary event recurrences after coronary artery bypass surgery (CABG).
