We report the case of a novel mitochondrial DNA mutation in the MT-ATP8 gene in an infant with tetralogy of Fallot. Next-generation sequencing was applied to sequence whole mitochondrial DNA of the patient. A known Leber's hereditary optic neuropathy-associated mutation (G9804A), a heteroplasmic T7501C mutation (17%), and a novel C8481 T Pro > Leu missense mutation in the MT-ATP8 gene was identified.

Objective: To demonstrate a detailed procedural guide for right ventricular outflow tract (RVOT) stent placement for palliation of tetralogy of Fallot and pulmonary stenosis in a patient weighing <2 kg.
Key Steps: Obtain wire position with an 0.018-inch Hi-Torque floppy wire in a distal branch pulmonary artery.

Objectives: To assess the surgical outcomes of atrioventricular septal defect associated with Tetralogy of Fallot (AVSD)-TOF repair performed at 2 specialized cardiac centers.
Methods: From May 2012 to December 2024, 20 patients diagnosed with AVSD-TOF who underwent surgical repair were included.
Results: The median age at the time of surgical repair was 13 months, with a median weight of 8.

Our previous research identified 12 small Cajal body-specific RNAs (scaRNAs) with reduced expression in the right ventricle in infant patients with tetralogy of Fallot. Likewise, we showed that there were significant changes in mRNA processing in the RV in these patients. ScaRNAs play a crucial role in the biochemical maturation of spliceosomal RNAs (pseudouridylation and 2'-O-methylation).

It is characterized by a congenital defect in the Spigelian fascia, resulting in a hernia along the semilunar line, often associated with intestinal obstruction. A hallmark feature is the presence of an ectopic testis, typically located within or immediately adjacent to the hernia sac.
