Why the study?
Occult ATTR-CA carries a poor postoperative prognosis in severe AS but is difficult to recognize before treatment using current diagnostic strategies.
Does myocardial ECV quantification using TAVR-planning CT identify occult ATTR-CA in patients with severe aortic stenosis?
Does myocardial ECV quantification using TAVR-planning CT identify occult ATTR-CA in patients with severe aortic stenosis?
Myocardial ECV quantification derived from routine TAVR-planning CT may serve as a diagnostic tool to identify occult cardiac amyloidosis in patients with severe aortic stenosis.
