Congenital Anomalies of the Aortic Arch
1Pediatric Cardiology, Johns Hopkins University Medical Center, 600 North Wolfe St., Baltimore, MD 21287.
Insights
This review examines isolated congenital aortic arch anomalies, including abnormal connections, obstructions, and formation defects like right aortic arches and vascular rings.
Area of Science:
- Cardiovascular Medicine
- Pediatric Cardiology
- Medical Imaging
Background:
- Congenital anomalies of the aortic arch are common cardiovascular malformations.
- These anomalies can occur independently or alongside intracardiac defects.
- Understanding isolated anomalies is crucial for diagnosis and management.
Purpose of the Study:
- To review congenital anomalies of the aortic arch occurring in isolation.
- To categorize these anomalies into distinct classes for clarity.
- To provide a foundational understanding for further research and clinical practice.
Main Methods:
- Literature review focusing on isolated congenital aortic arch anomalies.
- Categorization of anomalies into three main groups based on pathophysiology.
- Analysis of existing data on prevalence and presentation of isolated defects.
Main Results:
- Identified three primary categories of isolated aortic arch anomalies: abnormal aortopulmonary connections, aortic arch obstructions, and aortic arch formation defects.
- Specific examples include right aortic arches, vascular rings, and cervical aortic arches.
- Highlighted the importance of recognizing these in isolation despite frequent co-occurrence with intracardiac issues.
Conclusions:
- Congenital aortic arch anomalies present a spectrum of isolated defects.
- Classification aids in understanding the diverse presentations of these conditions.
- Further investigation into isolated anomalies is warranted for improved patient outcomes.
Abstract:
Congenital anomalies of the aortic arch can occur either in isolation or in conjunction with other intracardiac defects. This review will examine congenital aortic arch anomalies as if they occur in isolation, with the awareness that intracardiac defects often coexist. The three general classes of abnormalities to be reviewed are: (1) abnormal connections between the aorta and pulmonary arterial system; (2) aortic arch obstructions; and (3) defects in the formation of the aortic arch typified by right aortic arches, vascular rings, and cervical aortic arches.
