Etiologic factors of acute aortic dissection in children and young adults
Insights
Acute aortic dissection is a life-threatening condition in young people, often linked to congenital heart issues or connective tissue disorders. Early recognition of risk factors is crucial for timely diagnosis and intervention.
Area of Science:
- Cardiology
- Pediatric Medicine
- Genetics
Background:
- Acute aortic dissection is a rare but life-threatening condition in pediatric and young adult populations.
- Congenital cardiovascular anomalies and heritable connective tissue disorders are primary predisposing factors.
- Emerging associations include substance abuse and intense physical activities like weight lifting.
Purpose of the Study:
- To review current concepts in pathophysiology and predisposing conditions of acute aortic dissection in young individuals.
- To highlight salient physical findings associated with known predisposing conditions to facilitate early diagnosis.
- To increase physician awareness of risk factors for acute aortic dissection in pediatric and young adult patients.
Main Methods:
- Review of current literature on acute aortic dissection in children, adolescents, and young adults.
- Summary of clinical presentations and diagnostic imaging modalities.
- Identification and discussion of predisposing conditions and their physical findings.
Main Results:
- Congenital cardiovascular anomalies are the most common predisposing factor in this age group.
- Heritable connective tissue disorders significantly increase the risk of aortic dissection.
- Cocaine abuse and weight lifting represent newer, identified risk factors.
Conclusions:
- Physicians in acute care settings must be aware of predisposing conditions for acute aortic dissection in young patients.
- Early diagnosis is critical for managing this life-threatening condition.
- Information on risk factors can aid in assessing sudden death risk during sports preparticipation evaluations.
Abstract:
Current concepts in the pathophysiology and predisposing conditions of acute aortic dissection in children, adolescents, and young adults are presented. Timely diagnosis is required for this life-threatening condition. Most children and adolescents with aortic dissection have congenital cardiovascular anomalies. Certain heritable disorders involving connective tissue also predispose to this disorder. Newer associations include cocaine abuse and weight lifting. To facilitate early diagnosis, the salient physical findings of the known predisposing conditions are reviewed. Clinical presentation and diagnostic imaging of aortic dissection are briefly summarized. Physicians working in an acute care setting, particularly in the emergency room, should be aware of disorders predisposing to acute aortic dissection in the pediatric and young adult population. Practitioners conducting school or college preparticipation sports evaluations can make use of such information in their assessment of risk for sudden death.
