We report a case of a left atrial appendage aneurysm (LAAA) in a 16-year-old boy presenting with supraventricular tachycardia (SVT). The aneurysm was detected incidentally on a routine echocardiogram performed before an electrophysiology study for evaluation and management of the SVT. The aneurysm was successfully resected under cardiopulmonary bypass through video-assisted thoracoscopic surgery.

- Children and young adults with severe cardiac channelopathies may initially present with syncope or seizures due to irregular heartbeats, leading to reduced blood flow to the brain.
- Two significant genetic disorders causing arrhythmias—long QT syndrome and catecholaminergic polymorphic ventricular tachycardia—are highlighted, along with their unique symptoms and underlying mechanisms.
- Proper identification of these cardiac conditions can prevent misdiagnosis as epilepsy, allowing for timely treatment and preventing future episodes.
Objective: To assess the ability of urinary acute kidney injury biomarkers and renal near-infrared spectroscopy (NIRS) to predict outcomes in infants after surgery for congenital heart disease.
Methods: Urinary levels of neutrophil gelatinase-associated lipocalin (NGAL), interleukin-18 (IL-18), kidney injury molecule-1 (KIM-1), and cystatin C were measured preoperatively and postoperatively in 49 infants younger than 6 months of age. Renal NIRS was monitored for the first 24 hours after surgery.
Objective: To describe postoperative fluid overload patterns and correlate degree of fluid overload with intensive care morbidity and mortality in infants undergoing congenital heart surgery.
Design: Prospective, observational study. Fluid overload (%) was calculated by two methods: 1) (Total fluid in - Total fluid out)/(Preoperative weight) × 100; and 2) (Current weight - Preoperative weight)/(Preoperative weight) × 100.
