Do NT-proBNP levels differ among different types of Fontan circulation?
NT-proBNP levels are inherently higher in older types of Fontan circulation (APC/AVC) independent of cardiac status, requiring careful interpretation.
Levels of NT-pro BNP are related to the type of Fontan circulation. The older types (APC/AVC) that involve more atrial tissue in the systemic venous pathway show higher NT-proBNP levels independently of their cardiac status. Their NT-proBNP levels should be interpreted with care.
Heck et al. (Tue,) studied this question.
