Acute cardiovascular disorders are incriminated in up to 33% of maternal deaths, and the presence of sickle cell anemia (SCA) aggravates the risk of peripartum complications. Herein, we present a 24-year-old Caribbean woman with known SCA who developed a vaso-occlusive crisis at 36 weeks of gestation that required emergency Cesarean section. In the early postpartum period, she experienced fever with rapid onset of acute respiratory distress in the context of COVID-19 infection that required tracheal intubation and mechanical ventilatory support with broad-spectrum antibiotics and blood exchange transfusion.

Predicting mortality after transcatheter aortic valve replacement using AI-based fully automated left atrioventricular coupling index.

J Cardiovasc Comput Tomogr

January 2025

Department of Radiology and Radiological Science, Medical University of South Carolina, Charleston, SC, USA; Department of Diagnostic and Interventional Radiology, University Medical Center of Johannes Gutenberg-University, Mainz, Germany; German Centre for Cardiovascular Research, Mainz, Germany.

Background: This study aimed to determine whether artificial intelligence (AI)-based automated assessment of left atrioventricular coupling index (LACI) can provide incremental value above other traditional risk factors for predicting mortality among patients with severe aortic stenosis (AS) undergoing coronary CT angiography (CCTA) before transcatheter aortic valve replacement (TAVR).

Methods: This retrospective study evaluated patients with severe AS who underwent CCTA examination before TAVR between September 2014 and December 2020. An AI-prototype software fully automatically calculated left atrial and left ventricular end-diastolic volumes and LACI was defined by the ratio between them.

Comorbidities Associated With Different Degrees of Severity in Children and Young People Hospitalized With Acute COVID-19.

Pediatr Infect Dis J

January 2025

From the Innovation and Global Pediatric Infectious Disease, Biomedical Research Foundation of the University Hospital 12 de Octubre (FIBH12O), Instituto de Investigación Hospital 12 de Octubre (imas12), Madrid, Spain.

In this prospective cohort study with 2326 hospitalized children and young people with coronavirus disease 2019 in Spain and Colombia, 36.4% had comorbidities. Asthma, recurrent wheezing, chronic neurological, cardiac and pulmonary diseases significantly increased the risk of severe outcomes such as death, mechanical ventilation and intensive care unit admission.

Background: Right ventricular (RV) failure is a well-recognized pivotal prognostic factor of adverse outcomes in pulmonary artery hypertension (PAH), while RV dilation provides significant implications for adaptive or maladaptive changes. PAH is a predominant cause of mortality among patients with connective tissue disease (CTD). This study aims to elucidate the prognostic significance of RV morphology, as assessed by echocardiography (ECHO), in with CTD associated with PAH (CTD-PAH).

Background: Data on the predictive value of coronary computed tomography angiography-derived fractional flow reserve (CT-FFR) for long-term outcomes are limited.

Methods And Results: A retrospective pooled analysis of individual patient data was performed. Deep-learning-based CT-FFR was calculated.
