The Impact of Right Atrial Function on Prognosis and Renal Function in Patients With Tricuspid Regurgitation.

Tricuspid regurgitation (TR) is related to survival, and right atrial (RA) size and function may play a role. This study aimed to assess the impact of RA function measured by strain (RA strain [RAS]) on outcome and end-organ congestion. We enrolled 134 patients (mean age 73 ± 13 years, 62% women) with any TR grade or etiology and a complete echocardiogram, clinical follow-up, and renal function assessment.

Procoagulant phenotype of virus-infected pericytes is associated with portal thrombosis and intrapulmonary vascular dilations in fatal COVID-19.

Background & Aims: The underlying mechanisms and clinical impact of portal microthrombosis in severe COVID-19 are unknown. Intrapulmonary vascular dilation (IPVD)-related hypoxia has been described in severe liver diseases. We hypothesised that portal microthrombosis is associated with IPVD and fatal respiratory failure in COVID-19.

Epidemiology and outcomes of pediatric cardiac arrest in a cardiovascular unit at a public hospital in Argentina.

Background: Children with congenital heart disease present a higher frequency of cardiorespiratory arrest (CRA) than the general pediatric population. The epidemiology of CRA is not exactly known in our setting, nor are the mortality risk or the neurological evolution factors.

Objective: To describe the epidemiology and outcomes associated with pediatric cardiopulmonary resuscitation in a cardiovascular recovery unit.

Peak atrial longitudinal strain and risk stratification in moderate and severe aortic stenosis.

Aims: We sought to investigate the association of left atrial strain with the outcome in a large cohort of patients with at least moderate aortic stenosis (AS).

Methods And Results: We analysed 467 patients (mean age 80.6 ± 8.

Extracorporeal Membrane Oxygenation (ECMO) Training Program in A Pediatric Cardiac Intensive Care Unit: An 8-Year Single-Center Experience in Argentina.

Introduction: Extracorporeal membrane oxygenation (ECMO) for temporary cardiopulmonary support is one of the most intense and technologically complex therapies offered in medicine. It is a high-risk procedure that requires specific knowledge and technical skills to perform it with good results.

Objective: The main goal of this study is to describe our extracorporeal membrane oxygenation (ECMO) training program based on the study of specialized nurses and physicians of a simulation teaching experience, conducted in a pediatric cardiac intensive care unit.
