Association of body mass index and visceral fat with aortic valve calcification and mortality after transcatheter aortic valve replacement: the obesity paradox in severe aortic stenosis.

In non-obese, low VAF was associated with higher mortality, whereas a positive trend was apparent between VAF and all-cause death in the obese (MV-adjustment: 0.98 [95% CI (0.96; 0.99)]; p = 0.029 vs. 1.06 [95% CI (0.97; 1.10)], p = 0.385, for non-obese and obese, respectively; p value for BMI interaction of 0.04) (Table 3 ).
