AI Article Synopsis
- The study outlines a novel surgical approach that combines coronary artery bypass surgery with the implantation of autologous rectus muscle and greater omentum to enhance blood vessel formation (angiogenesis) and muscle cell growth (myogenesis) in damaged heart tissue.
- Post-surgery results showed a significant increase in patient heart function, with left ventricular ejection fraction improving from 0.15 to 0.40 and exercise tolerance doubling.
- Imaging techniques confirmed improved heart tissue viability and blood flow in the affected areas, suggesting this combined surgical technique may be beneficial for patients with heart muscle damage.
Article Abstract
We describe a procedure to promote angiogenesis and impregnation of skeletal myoblast into infarcted myocardium. At the completion of coronary artery bypass surgery, the midline sternotomy incision was extended to open the abdomen, and the greater omentum was tailored to reach the myocardium. Four pieces of autologous rectus muscle were applied to the infarcted left ventricle. This implantation was reinforced by the greater omentum. Incisions were closed in the usual manner. Postoperatively, the patient showed significant improvements in left ventricular ejection fraction (from 0.15 to 0.40) and in exercise tolerance (from 3 METs to 6 METs, or 100%). Computed tomographic angiography and positron emission tomography demonstrated improved myocardial viability and vascularity in the ischemic segments of the left ventricle. Omentopexy and cell patch cardiomyoplasty in conjunction with coronary artery bypass surgery may stimulate myogenesis and angiogenesis in avascular, dyskinetic scar tissue of left ventricle; in this preliminary study, this procedure appeared to improve the functional capacity of the left ventricle.

Are we systematically overdosing women? Revisiting standardized contrast protocols for thoracoabdominal CT scans.
Eur Radiol
January 2025
Department of Diagnostic and Interventional Radiology, University Hospital Augsburg, Augsburg, Germany.
Objectives: The purpose of this study was to evaluate whether the iodine contrast in blood and solid organs differs between men and women and to evaluate the effect of BMI, height, weight, and blood volume (BV) on sex-specific contrast in staging CT.
Materials And Methods: Patients receiving a venous-phase thoracoabdominal Photon-Counting Detector CT (PCD-CT) scan with 100- or 120-mL CM between 08/2021 and 01/2022 were retrospectively included in this single-center study. Image analysis was performed by measuring iodine contrast in the liver, portal vein, spleen, left atrium, left ventricle, pulmonary trunk, ascending and descending aorta on spectral PCD-CT datasets.
Right Ventricle Function: The Role of the Forgotten Chamber in Mitral Valve Surgery.

Background: Referred to as the "forgotten chamber," the right ventricle (RV) is now widely acknowledged as a significant factor, particularly in certain cardiovascular pathologies. Despite historically being undervalued in comparison to the left ventricle, the RV function is deemed crucial in determining patient outcomes following mitral valve (MV) surgery. In the context of MV surgery, it is important to note that the RV is highly susceptible to dysfunction before, during, and after the surgical procedure.

Since FTD exhibits distinct regional atrophy patterns on magnetic resonance imaging (MRI), AI-aided automated brain volume analysis could enhance the clinical diagnostic assessment of FTD, including the detection of the disease and the classification of subtypes, which encompass behavioral variant (BV), semantic variant (SV), and progressive non-fluent aphasia (PNFA). In this study, we leverage automated brain volumetry software to approach both FTD detection and the differential diagnosis among its subtypes.

Aim: Comparative assessment of structural changes in cardiomyocyte mitochondria of the right atrial appendage and the mitochondrial respiratory function in peripheral blood leukocytes in a cohort of patients after acute decompensated heart failure (ADHF) and with stable chronic heart failure of ischemic etiology with reduced ejection fraction (CHFrEF) or moderately reduced ejection fraction (CHFmrEF) of the left ventricle.
Material And Methods: The study analyzed 40 micrographs of right atrial appendage cardiomyocytes obtained from 12 patients with CHFrEF and CHFmrEF. The study protocol was registered on ClinicalTrials.

Background: While we know dementia in Alzheimer's disease (AD) results from the accumulation of β-amyloid (Aβ), tau pathology, and hippocampus atrophy (HC), it is still unclear how these factors impose cognitive decline.
Method: We used Structural Equation Models (SEM; lavaan R package) to explore the complex relationships between the neurobiological factors in the early stages preceding AD dementia in the TRIAD cohort. Our sample comprised 333 timepoints of neuropsychological evaluation (MoCA), structural MRI, Aβ ([18F]AZD4694), and tau ([18F]MK6240) PET of cognitively healthy (NC) and mild cognitive impaired (MCI) participants.
