With the recent advances in pediatric cardiology and cardiovascular surgery, assessment of ventricular function in single ventricle complexes is becoming increasingly important. The serial assessment of ventricular function helps our understanding of the natural and unnatural history in these patients. Equilibrium radionuclide ventriculography is safe, easy to perform, and well-suited to the serial assessment of ventricular function. Fifteen nuclear studies were performed in 15 children with single ventricle complex. Nuclear studies were imaged in both the anterior and left anterior oblique views in each patient. The ventricular ejection fraction calculated from the anterior view (the view with the best atrial-ventricular separation) closely approximated the cineangiographic ejection fraction (54.0 vs 59.1%). Equilibrium radionuclide ventriculography is a valid method to calculate ventricular ejection fraction in single ventricle. The anterior view should be used for region of interest selection and subsequent ejection fraction analyses.

Background: The Fontan procedure is a surgical intervention designed for patients with single ventricle physiology, wherein the systemic venous return is redirected into the pulmonary circulation, thereby facilitating passive pulmonary blood flow without the assistance of ventricular propulsion. Consequently, long-term follow-up of individuals who have undergone the asymptomatic Fontan procedure is essential.
Objectives: The aims of this investigation were to: 1) examine the impact of flow components and kinetic energy (KE) parameters on hemodynamic disturbances in asymptomatic Fontan patients and control group; 2) Assess left ventricular diastolic dysfunction through the analysis of 4D flow parameters across different Fontan sub-groups; 3) Compare intracardiac flow parameters among Fontan sub-groups based on morphological features of the left ventricle (LV) and right ventricle (RV).

Introduction: Peripartum cardiomyopathy (PPCM) is a pregnancy related cardiomyopathy with a high potential for recovery. One of the contemporary predictors studied in cardiomyopathy is right ventricular (RV) function during initial presentation.
Purpose: This study aimed to determine the role of RV systolic function based on the various RV function parameters by two-dimensional transthoracic echocardiography (2DE) to predict PPCM recovery within 6 months of follow-up and identify the most accurate parameter among them.

Purpose: The purpose of this study was to determine the normal variations of myocardial T1, T2, and T2* relaxation times on cardiac MRI obtained at 1.5 T in healthy, sex-balanced volunteers aged between 18 and 69 years.
Material And Methods: A total of 172 healthy volunteers were recruited prospectively.

The discovery of Kisspeptin (Kiss) has opened a new direction in research on neuroendocrine control of reproduction in vertebrates. Belonging to the RF amide family of peptides, Kiss and its cognate receptor Gpr54 (Kissr) have a long and complex evolutionary history. Multiple forms of Kiss and Kissr are identified in non-mammalian vertebrates, with the exception of birds, and monotreme mammals.
