Article Abstract
Accurate segmentation of cardiac chambers is helpful for the diagnosis of Congenital Heart Disease (CHD) in fetal echocardiography. Previous studies mainly focused on single cardiac chamber segmentation, which cannot provide sufficient information for the cardiologists. In this paper, we present an instance segmentation approach capable of segmenting four cardiac chambers accurately and simultaneously. A novel object proposal recovery strategy is further deployed to retrieve possible missing objects. To alleviate the shortage of medical data and further improve the segmentation performance, we utilize a rotation and distortion method for data augmentation. Experiments on a fetal echocardiography dataset of 319 fetuses demonstrate that the proposed approach can achieve superior performance according to common-used evaluation metrics.Clinical relevance-This can be used to help the cardiologists to better analyze the structure and function of the fetal heart.

Mitral annular disjunction distance is associated with adverse outcomes in children and young adults with connective tissue disorders.

Introduction: Mitral annular disjunction (MAD) is a pathologic fibrous separation of the mitral valve hinge point from the ventricular myocardium. The aims of this study were to describe the range of MAD distance by cardiac magnetic resonance (CMR) in children and young adults with connective tissue disorders (CTDs) versus a healthy control sample, and to assess the MAD distance as a predictor of adverse cardiovascular outcomes.
Methods: This was a retrospective, single-center study of healthy subjects and patients with Marfan syndrome, Loeys-Dietz syndrome, Ehlers-Danlos syndrome, or nonspecific CTD who underwent CMR between 01/01/2000 and 01/01/2020.

Approximately 0.8 % of all children are born with heart defects, with the prenatal incidence naturally being even higher. Among all congenital heart defects (CHD), conotruncal anomalies are the most common critical heart defects - after ventricular and atrial septal defects.

Resistance arteries, which include small arteries and arterioles, play essential roles in regulating blood pressure and tissue perfusion. Dysfunction in these arteries can lead to various cardiovascular conditions such as hypertension, atherosclerosis, and heart failure, as well as neurovascular conditions. The examination of human resistance arteries is crucial for understanding cardiovascular disease mechanisms and developing targeted therapeutic strategies.

Cor triatriatum is a rare congenital heart defect that divides the right or left atrium into three chambers. Although the diagnosis is typically made within the first years of birth, it can occasionally be made later in adulthood and is frequently associated with other cardiac defects but may be present in isolation. Clinical manifestations range from lung congestion, exhaustion, coughing, and dyspnea to the onset of heart failure.

Background: Pacemaker implantation has become a routine procedure in contemporary cardiology. Several possible complications during and after the procedure have been described, with this article focusing on the rare complication and the prevention of left-sided lead placement after arterial puncture.
Case Summary: A 90-year-old female patient was admitted to our hospital due to recurrent transient ischaemic attacks following a dual-chamber pacemaker implantation six weeks earlier.
