Why the study?
What are the morphologic characteristics of the left atrial appendage, roof, and septum in patients with atrial fibrillation compared to controls?
What are the morphologic characteristics of the left atrial appendage, roof, and septum in patients with atrial fibrillation compared to controls?
Considerable variations in LAA and LA roof morphologies, including roof pouches and septal ridges, exist and can be delineated by CT imaging to guide AF ablation and avoid complications.
No takes yet. Share an insight, caveat, or question.
Larger LAA dimensions were associated with AF; leaves open whether CT anatomy improves ablation outcomes.
Wongcharoen et al. (2006) studied this question.
