Why the study?
Does aortic valve replacement alter aortic root motion in patients with aortic valve disease?
Does aortic valve replacement alter aortic root motion in patients with aortic valve disease?
Aortic root motion increases after AVR for aortic stenosis, which may theoretically increase mechanical stress and the risk of late aortic dissection.
No takes yet. Share an insight, caveat, or question.
May heighten late dissection risk after AVR for AS; leaves open differential aortic wall stress by preoperative pathology.
Beller et al. (2008) studied this question.
