Clinical Outcomes in Patients With Bicuspid Aortic Valves and Ascending Aorta ≥50 mm Under Surveillance.

Background: Clinical outcomes of bicuspid aortic valve (BAV) patients with ascending aortic diameters ≥50 mm who are under surveillance are poorly defined.

Objectives: The purpose of this study was to assess clinical outcomes in BAV patients with ascending aorta ≥50 mm.

Methods: Multicenter retrospective cohort study of BAV adults with ascending aorta diameters ≥50 mm by transthoracic echocardiography (TTE).

[Mortality predictors in patients with native valve infective endocarditis].

Introduction: Mortality of infective endocarditis (IE) in Argentina continues to be high. The aim objective was to describe the clinical characteristics and identify factors associated with in-hospital and long-term mortality in patients with native valve IE.

Methods: Retrospective cohort study including adult patients with diagnosis of native valve IE, hospitalized during 2011-2021.

Looking for a definition of aortic dilatation in overweight and obese individuals: body surface area-indexed values versus height-indexed diameters.

Introduction: Patient's body size is a significant determinant of aortic dimensions. Overweight and obesity underestimate aortic dilatation when indexing diameters by body surface area (BSA). We compared the indexation of aortic dimensions by height and BSA in subjects with and without overweight to determine the upper normal limit (UNL).

Population attitude and access to the healthcare system during the COVID-19 pandemic.

The COVID-19 pandemic elicited important changes in community habits and behaviors, including a distancing of people from the healthcare system. The objective of this work was to understand the causes that gave rise to changes in behavior from an individual perspective in the Argentine Republic. We performed a cross-sectional, web-based survey using an online questionnaire.

Worsening renal function in patients admitted with acute decompensated heart failure: incidence, risk factors and prognostic implications.

Introduction And Objectives: Acute decompensated heart failure (ADHF) is a common cause of hospital admission and is associated with an increased risk of worsening renal function (WRF). The aims of this study were to investigate the incidence and predictors of WRF in patients admitted for ADHF and to assess the prognostic significance of WRF at 1 year.

Methods: A retrospective analysis of data on 200 consecutive patients admitted with ADHF was carried out.
