Oxygen step up in right atrium – MCQ – Answer Step up in oxygen saturation on cardiac catheterization in the right atrium is suggestive of – Correct answer: a) Atrial septal defect In ventricular septal defect oxygen step up is seen at ventricular level. For example, if the oxygen saturation is 64% in the right atrium, it becomes 82% in the right ventricle due to entry of oxygenated blood from the left ventricle across the ventricular septal defect. In patent ductus arteriosus, oxygen step up is noted at the level of the pulmonary artery. Back to question

Rationale: Atrioventricular reentrant tachycardia (AVRT) is the most common supraventricular tachycardia occurring in children. However, in complex congenital heart disease patients with a different heart anatomy and conduction system morphology, accessory pathway modification may be particularly challenging because of distortion of typical anatomic landmarks. Patient concerns: A 10-year-old boy with tricuspid atresia and history of bidirectional Glenn operation had recurrent chest distress and palpitation for 3 months. He had multiple hospitalizations for narrow-QRS tachycardia with poor hemodynamic tolerance, despit...

CONCLUSIONS Although prediabetes, hyperuricemia, and dyslipidemia were all more prevalent in patients with inoperable left-to-right shunts, only prediabetes was found to be significantly associated with higher pulmonary vascular resistance. PMID: 29705813 [PubMed - in process]

This study evaluated the safety and acute haemodynamic effects of inhaled iloprost in children with PAH associated with congenital heart disease (CHD). Children with PAH –CHD who underwent cardiac catheterization and iloprost administration in our catheter laboratory between June 2007 and October 2015 were included. Iloprost was administered by atomization inhalation and changes in hemodynamic parameters were recorded. In total, 100 children with PAH–CHD were en rolled. Median age was 13 [1.5–18.0] years and 34% were male. A ventricular septal defect was present in 84%, a patent duct in 12%, a complete at...

Purpose: The aim of the study was to assess the detection of congenital cardiovascular anomalies (congenital heart disease) in neonates and infants using model-based iterative reconstruction (MBIR) algorithm compared with hybrid iterative reconstruction (HIR) and filtered back projection (FBP) reconstructions on axial computed tomography (CT) performed at minimum scanner dose. Materials and Methods: Over 1 year, all CT angiographies performed in infants below 3 months of age with congenital heart disease were assessed retrospectively. All were scanned on a 256-slice CT (Brilliance iCT) using single axial rotation at minim...
