The rare case of an adult with a double-chambered left ventricle was revealed using multimodality imaging using echocardiography and cardiac magnetic resonance imaging in a 38-year-old asymptomatic male patient. The congenital malformation was dominated by a second, coarsely trabeculated muscular shelf dividing the left ventricle into 2 chambers without signs for left ventricular inflow or outflow tract obstruction. The partition wall did not show any signs for intramyocardial fibrosis in late gadolinium enhancement cardiovascular magnetic resonance imaging. Flow measurements excluded a relevant intracardial shunt across the additive perimembranous ventricular septal defect. There were no signs for global right and left ventricular dysfunction with left and right ventricular volumes and ejection fraction within normal limits. A conservative approach was recommended. In summary, we are able to present the case of an adult with a double-chambered left ventricle with a second muscular "septum" partially dividing the left ventricular cavity without causing a relevant impact on cardiac function or clinical signs for heart failure.

Assessment of hemodynamic disturbances and impaired ventricular filling in asymptomatic fontan patients: A 4D flow CMR study.
Eur J Radiol Open

Department of Radiology, Shanghai Children's Medical Center, Shanghai Jiao Tong University School of Medicine, 1678 Dong Fang Road, Shanghai 200127, PR China.
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).

Cardiac stereotactic body radiotherapy is a promising noninvasive treatment for patients with refractory ventricular tachycardia. With the aim to prove feasibility of a novel image guided radiotherapy and heart motion gating device, cardiac proton radiotherapy was performed using a porcine model. Using a novel adaptation of γ - H2AX tissue staining techniques, we have been able to localize a radiation beam in large animal tissue to assess targeting accuracy within a defined field.

Background: This study aimed to assess right ventricular (RV) endocardial fibroelastosis (EFE) in fetuses with critical pulmonary stenosis (CPS) and pulmonary atresia with intact ventricular septum (PA-IVS) and to investigate the implications of RV EFE for circulatory outcomes.
Methods: Fetal echocardiographic data from July 2018 to January 2021 were collected. Three reviewers independently graded EFE based on the presence and extent of endocardial echogenicity.
The Advances in Utilizing Right Ventricular Function as a Predictor of Peripartum Cardiomyopathy Recovery: A Single Centre Prospective Cohort Study.

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.
Ventricular Depolarization Abnormalities and Their Role in Cardiac Risk Stratification - A Narrative Review.

Ventricular depolarization refers to the electrical activation and subsequent contraction of the ventricles, visible as the QRS complex on a 12-lead electrocardiogram (ECG). A well-organized and efficient depolarization is critical for cardiac function. Abnormalities in ventricular depolarization may indicate various pathologies and can be present in all leads if the condition is general, or in a subgroup of anatomically contiguous leads if the condition is limited to the corresponding anatomic location of the heart.
