Visceral fat patterns were associated with higher TAVR mortality; leaves open whether CT VAF assessment refines risk stratification beyond BMI.
Does body mass index and visceral fat associate with aortic valve calcification and mortality in severe aortic stenosis patients undergoing TAVR?
Pre-intervention assessment of visceral abdominal fat by CT provides better mortality discrimination than BMI alone in patients undergoing TAVR, revealing that low visceral fat in non-obese and high visceral fat in obese patients are associated with higher mortality.
