aortic root dilatation
Pathological enlargement of the aortic root structures requiring surgical intervention.
Full Definition
Aortic root dilatation involves enlargement of the aortic sinuses, sinotubular junction, or ascending aorta, often associated with aortic regurgitation or connective tissue disorders. Surgical options include valve-sparing root replacement (David or Yacoub procedures) or composite root replacement with mechanical or biological conduits. Anesthetic considerations include managing acute aortic regurgitation, potential for aortic dissection, and complex surgical reconstruction requiring prolonged cardiopulmonary bypass times.
Usage
Usage note: British spelling uses 'dilatation' while American usage often favors 'dilation'.
