AI Article Synopsis

  • Cardiovascular diseases significantly impact children with chronic renal failure, making cardiac evaluations important before and after kidney transplants.
  • A study analyzed echocardiography data from 55 pediatric patients, comparing their cardiac health before and after transplantation by looking at various measurements like left ventricular dimensions and function over a 6-month period.
  • Results showed that kidney transplants led to important improvements in heart structure and function, highlighting the need for ongoing cardiac monitoring in these patients to ensure better health outcomes.

Article Abstract

Objectives: Cardiovascular diseases are an important cause of mortality and morbidity in children with chronic renal failure. Cardiac evaluation and followup are crucial for these patients before and after renal transplant. Echocardiography is a noninvasive imaging modality that allows for the assessment of cardiac structure and function.

Materials And Methods: We retrospectively investigated pretransplant and posttransplant echocardiography findings for 55 pediatric patients who had underwent kidney transplant. We recorded patient characteristics before and after transplant, including age, sex, follow-up period, etiology of renal failure, left ventricular systolic and diastolic diameters and the associated z scores, left ventricular mass indexes and z scores, ejection fraction and fractional shortening, aortic valve and atrioventricular valve insufficiencies, presence of pulmonary hypertension, and pericardial effusion (if any) in echocardiography. All participants underwent echocardiography at baseline and after 6 months following the transplant procedure.

Results: Posttransplant echocardiography evaluations showed that the z scores of left ventricular systolic and diastolic diameters decreased significantly, mitral regurgitation decreased, and left ventricular systolic functions and left ventricular mass index increased.

Conclusions: Our study revealed that kidney transplant has a beneficial effect on the cardiovascular status of patients with end-stage renal disease, as shown by improvements in both structural and functional echocardiographic features. Cardiac functions must be monitored regularly before and after transplant. Transplantation is the optimal treatment option for preservation and improvement of cardiovascular functions.

Introduction: Dilated cardiomyopathy (DCM) is a leading cause of heart failure (HF) characterized by left ventricular dilatation and systolic dysfunction not explained by abnormal loading conditions. Despite its prevalence, DCM's epidemiology and prognosis remain poorly studied in our country.

Material And Methods: A retrospective observational study encompassed patients discharged from all Spanish public hospitals between 2016 and 2021 diagnosed with DCM.

Department of Mechanical and Aerospace Engineering, University of Central Florida, and the Biomedical Acoustics Research Company, 32816, Orlando, FL, USA.

Background: Seismocardiographic signals (SCG) are chest wall vibrations induced by mechanical cardiac activities. This study investigated the morphological changes in the SCG signal due to respiration and exercise.

Methods: Fifteen healthy subjects were recruited, and SCG was acquired before and after exercise.

Department of Radiology, Mianyang Central Hospital, School of Medicine, University of Electronic Science and Technology of China, No. 12 Changjia Lane, Alarm Bell St, Fucheng District, Mianyang 621000, China. Electronic address:

Purpose: To investigate differences in left ventricular wall thickness (LVWT) measurements between end-diastole and mid-diastole using cardiac computed tomography (CCT) and establish LVWT reference values stratified by phase, sex, and region.

Methods: Subjects who underwent CCT without a history of cardiovascular disease or risk factors were retrospectively included between 2021 and 2024. LVWT was manually measured in each segment according to the American Heart Association's 17-segment model at end-diastole and mid-diastole.

Background And Objective: Left ventricular myocardium segmentation is of great significance for clinical diagnosis, treatment, and prognosis. However, myocardium segmentation is challenging as the medical image quality is disturbed by various factors such as motion, artifacts, and noise. Its accuracy largely depends on the accurate identification of edges and structures.

Patients with congenitally corrected transposition of the great arteries (ccTGA) can be treated with a double switch operation (DSO) to restore the normal anatomical connection of the left ventricle (LV) to the systemic circulation and the right ventricle (RV) to the pulmonary circulation. The subpulmonary LV progressively deconditions over time due to its connection to the low pressure pulmonary circulation and needs to be retrained using a surgical pulmonary artery band (PAB) for 6-12 months prior to the DSO. The subsequent clinical follow-up, consisting of invasive cardiac pressure and non-invasive imaging data, evaluates LV preparedness for the DSO.
