The majority of children with CHD who underwent tracheostomy did so for ventilator dependence and tracheomalacia and had coexisting genetic syndromes. About half the cohort died; among survivors, readmissions were common but decreased after the first year. These results underscore the ongoing mortality and morbidity risks faced by this vulnerable population.

Swallowing-induced tachycardia is a rare phenomenon, with only 50 cases documented worldwide. We present a unique case of an adolescent with hypertrophic cardiomyopathy (HCM) who presented with palpitations and a near syncopal episode. The patient was found to have a swallowing-induced atrial tachycardia. He underwent radiofrequency isolation of the right superior pulmonary vein and ablation of the right anterior ganglionated plexus, which led to a resolution of his symptoms. This case highlights the possible association between HCM and autonomic instability as potential aetiological mechanism for the tachycardia.

Fetal dilated cardiomyopathy is a rare anomaly characterized by ventricular dilation and dysfunction. Its causes are diverse, and its outcomes are generally dismal. We describe a rare case of prenatally diagnosed left ventricular apical aneurysm that progressed rapidly to dilated cardiomyopathy. At age 2 months, the infant underwent heart transplantation. Pathologic examination of the explanted heart revealed that the cause of the dilated cardiomyopathy was glycogen storage disease. This case highlights the crucial roles of timely diagnosis, frequent close monitoring, and multidisciplinary care in achieving a successful postnatal outcome.
