Title : Cinecoronariographic arterial standardization in univentricular heart
Abstract:
Background: Univentricular heart (UH) is a rare congenital heart malformation, characterized by the absence of two well-developed ventricles and the presence of a single functional ventricle. In these cases, cardiac magnetic resonance imaging or catheterization can be used for preoperative evaluation, although there is no consensual anatomical description of the pattern of coronary branches in UH.
Objective: To estimate anatomical patterns of coronary arteries in children with UH using coronary angiography.
Methods: Data will be collected from electronic medical records of 30 pediatric patients with UH undergoing cinecoronary angiography in the Hemodynamics sector, from January 2024 to January 2026. Anatomical cinecoronary angiography data will be compared with 30 cinecoronary angiography considered normal in adult patients. All exams will be performed on the Azurion equipment, model Azurion7 M20 ClarityIQ Philips Medical Systems, according to the Consensus guidelines of the American Heart Association. Variables to be considered will include age, gender, ethnic group, weight, height, absence or presence of coronary dominance, absence of specific coronary branches, absence or presence of a single coronary trunk, site of origin (aortic vestibule or ascending part of the aorta artery or pulmonary trunk or other). Statistical analyzes will be obtained using the SPSS Statistics software version 23.0 and will include measures of central tendency (mean and standard deviation) of the branches found, as well as relative frequency (percentage) and combinatorial analysis, with results of independence between the proposed variables evaluated by the P value at 5% significance.
Audience Take Away:
- Possible new anatomical patterns of coronary arteries in children with UH using cinecoronary angiography
- Better understand anatomical patterns of coronary arteries in children with UH
- This research can be extended so that other professionals can increase their understanding of coronary arterial branches in children with UH
- This study could facilitate, in the future, a surgical procedure, facilitating the work of a professional as it can establish anatomical patterns of the coronary arteries
