Why the study?
Does the presence and severity of mitral annular calcification predict mortality and complications in patients with severe aortic stenosis undergoing TAVR?
Does the presence and severity of mitral annular calcification predict mortality and complications in patients with severe aortic stenosis undergoing TAVR?
Severe mitral annular calcification is present in nearly 10% of TAVR patients and independently predicts increased all-cause mortality and the need for permanent pacemaker implantation.
No takes yet. Share an insight, caveat, or question.
Severe MAC may identify higher-risk TAVR patients; leaves open impact on selection or planning in observational data.
Abramowitz et al. (2016) studied this question.
