Atrial septal aneurysm (ASA) is a rarely reported fetal finding. Its definition is variable, but the diagnosis is usually made when the foramen ovale flap extends at least halfway across the left atrium. It is considered a transient, self-limiting condition, but on occasion, it can be complicated by fetal arrhythmia or left ventricular (LV) inflow obstruction-if longstanding, this can lead to left heart hypoplasia. We present two cases of ASA diagnosed at the second trimester scan, one of which was subsequently complicated by LV inflow obstruction and prenatal suspicion of hypoplastic aortic arch. This report is a good illustration of how structure follows function: a small LV preload can lead to a decreased LV output, which in turn will end up in a hypoplastic LV and outflow tract-all this is reversible after birth, due to the physiological circulatory modifications that occur in the newborn.

Macrophages are known to support cardiac development and homeostasis, contributing to tissue remodeling and repair in the adult heart. However, it remains unclear whether embryonic macrophages also respond to abnormalities in the developing heart. Previously, we reported that the structural protein Sorbs2 promotes the development of the second heart field, with its deficiency resulting in atrial septal defects (ASD).

Background: Several studies have demonstrated a notable increase in the incidence of atrial arrhythmias among individuals with atrial septal defect (ASD) occluder. Although the sequential dilation technique has been proposed as the mainstream technique for transseptal puncture with ASD occluder, it is associated with substantial risks and technical difficulties.
Case Summary: We report a patient who underwent catheter ablation for atrial fibrillation and had a large ASD occluder.

Our patient presented to the emergency room following a motor vehicle accident. The traumatic tricuspid valve rupture was diagnosed by transthoracic echocardiogram, and his respiratory status declined rapidly. He was placed on veno-venous extracorporeal membrane oxygenation (VV ECMO) to bridge him to surgical repair.

Background: Mitral valve prolapse (MVP) is a common cardiac valvular anomaly that can be caused by mutations in genes of various biological pathways. Individuals of three generations of a kindred presented with apparently dominant heredity of isolated MVP.
Methods: Clinical evaluation and echocardiography for all complying family members (n=13).
