Why the study?
Does preventive aortic surgery at the time of AVR prevent aortic dissection or rupture in patients with a dilated ascending aorta (40 to 50 mm)?
Does preventive aortic surgery at the time of AVR prevent aortic dissection or rupture in patients with a dilated ascending aorta (40 to 50 mm)?
Preventive aortic surgery should be considered during AVR for patients with mild ascending aorta dilation (40-50 mm) to prevent future dissection or rupture.
No takes yet. Share an insight, caveat, or question.
Challenges 50 mm threshold; leaves open whether preventive surgery at AVR reduces events in 40-50 mm dilation.
Matsuyama et al. (2005) studied this question.
