Cross-sectional cardiac anatomy was studied by computed tomography (CT) in normal patients and in patients with well documented cardiac pathology. Specific cardiac chambers, aortic and pulmonary artery enlargement, ventricular aneurysms, coronary artery, and intracardiac calcifications were demonstrated using a 3 sec scan time with and without intravenous iodinated contrast media. Although CT imaging of the heart is in its infancy, the clarity with which cardiac chambers and other structures were visualized is encouraging and suggests the potential value of CT scanning for detecting significant intracardiac pathology on routine thoracic CT scans.

Accurate Reconstruction of Right Heart Shape and Motion From Cine-MRI for Image-Driven Computational Hemodynamics.
Int J Numer Method Biomed Eng

Accurate reconstruction of the right heart geometry and motion from time-resolved medical images is crucial for diagnostic enhancement and computational analysis of cardiac blood dynamics. Commonly used segmentation and/or reconstruction techniques, exclusively relying on short-axis cine-MRI, lack precision in critical regions of the right heart, such as the ventricular base and the outflow tract, due to its unique morphology and motion. Furthermore, the reconstruction procedure is time-consuming and necessitates significant manual intervention for generating computational domains.

Objectives: To investigate the clinical value of fetal heart quantification (fetal HQ) in the evaluation of normal fetal heart size, morphology, and cardiac function at different gestational weeks.
Materials And Methods: A total of 101 pregnant women diagnosed with a healthy fetus by fetal echocardiography from September 2021 to December 2023 were selected and classified into four different periods of gestational weeks: 20-28 weeks (25 cases), 29-32 weeks (26 cases), 33-36 weeks (26 cases), and 37-40 weeks (24 cases). Quantitative analyses were performed by automatically tracking the endocardium using fetal HQ software that comes with the Voluson E10 from GE.
Sequential Double-Lung Transplantation In Kartagener Syndrome: A Case Report.

October 2024
Thoracic Surgery Department - Hospital de Santa Marta, Centro Hospitalar Universitário Lisboa Central, Portugal.
Kartagener syndrome (KS) is a rare congenital disorder, characterized by sinusitis, bronchiectasis and situs inversus. Lung transplantation is an effective treatment for end-stage lung failure, but dextrocardia and differences between hilar structures and pulmonary lobes require adjustments to conventional surgical technique. We present a case of a double-lung transplant without extracorporeal oxygenation in a 48-year-old male patient with KS.

Aims: Hepcidin regulates plasma and tissue iron levels. We studied the association of hepcidin levels with the risk of incident heart failure (HF) and cardiac dysfunction in older adults.
Methods: We included adults from the ongoing, longitudinal Atherosclerosis Risk in Communities (ARIC) study who were free from prevalent anemia and HF at Visit 5 (2011-2013) and had available hepcidin and covariate data.
Occupational exposures and coronary heart disease in the Hamburg City Health Study (HCHS) - a cross-sectional study.
BMC Public Health
January 2025
Institute for Occupational and Maritime Medicine (ZfAM), University Medical Center Hamburg-Eppendorf (UKE), Hamburg, Germany.
Background: Coronary heart disease (CHD) is the leading cause of death among adults in Germany. There is evidence that occupational exposure to particulate matter, noise, psychosocial stressors, shift work and high physical workload are associated with CHD. The aim of this study is to identify occupations that are associated with CHD and to elaborate on occupational exposures associated with CHD by using the job exposure matrix (JEM) BAuA-JEM ETB 2018 in a German study population.
