  1. dFLC Difference between involved and uninvolved serum free light chain, NT-proBNP N-terminal pro-brain natriuretic peptide, NYHA New York Heart Association, CR complete response, VGPR very good partial response.
  2. aAlthough this patient had IIIb disease based on cardiac biomarkers, the elevated cardiac biomarkers were clinically deemed to be secondary to renal failure and patient being on peritoneal dialysis (and not from advanced heart involvement).
