Coronary ostial atresia seen with pulmonary atresia and coronary-cameral fistulae or, more rarely, in isolation manifested as left main coronary artery atresia, is well described. We describe the clinical course and post-mortem findings in a neonate who suffered a fatal cardiac arrest and was found to have congenital absence of both coronary ostia in a single/common coronary system.

Abnormal development of the second heart field significantly contributes to congenital heart defects, often caused by disruptions in tightly regulated molecular pathways. , a gene encoding a protein with SET and MYND domains, is essential for heart and skeletal muscle development. Mutations in SMYD1 result in severe cardiac malformations and misregulation of expression in mammals.

Background: Congenital mesoblastic nephroma represents 3-10% of all pediatric renal tumors. With the advancement of ultrasound diagnostics and magnetic resonance imaging, the diagnosis of this renal neoplasm is increasingly being established prenatally and at birth. It usually presents as a benign tumor, but it can severely affect pregnancy outcomes, contributing to perinatal morbidity and mortality.

Background: The mitroaortic intervalvular fibrosa is an avascular structure near the left ventricular outflow tract, between the mitral and aortic valves. Mitroaortic intervalvular fibrosa complications, such as tamponade, hemopericardium, and abscesses, are rare and often diagnosed postmortem. On the other hand, the COVID-19 pandemic notably impacted pediatric patients with congenital heart diseases, who frequently presented cardiac complications including arrhythmias, elevated troponins, myocarditis, and heart failure.
