Maternal MACE events

Subject	Age	Type of CM	EF (%)	Delivery location	Arterial line	CVC	Delivery type	MACE event*
1	18	Other	20	Obstetric operating room	Yes	No	Caesarean section	NICM that required initiation of DBA therapy 9 months post partum. Presented 12 months post partum with ADHF and cardiogenic shock resulting in maternal death.
2	26	Other	30	Obstetric operating room	Yes	Yes	Vaginal	Intrapartum sustained wide complex arrhythmia.
3	33	Other	30	Heart hospital	Yes	Yes	Vaginal	NICM with prior DBA use. Required peripartum DBA weaned 48 hours after delivery.
4	22	Other	20	Heart hospital	Yes	No	Operative vaginal	History of NICM with severe systolic dysfunction requiring Milrinone peripartum; weaned postpartum day 16. Declined for LVAD due to small LV cavity size.
5	30	PPCM	30	Heart hospital	Yes	No	Vaginal	DBA initiated at time of labour induction, weaned off post partum day 6. Several runs of NSVT during delivery admission. Postpartum life vest.
6	44	PPCM	35	Heart hospital	Yes	Yes	Caesarean section	Chronic PPCM with acute worsening of systolic function initiated on peripartum DBA; weaned postpartum day 8.

*Referring to composite MACE events include: maternal death, inotrope use, LVAD, OHT or listingstatus change, acute decompensated heart failure or sustained ventricular arrhythmia up to 1-year post partum.
ADHF, acute decompensated heart failure; CM, cardiomyopathy; CVC, central venous catheter; DBA, dobutamine; EF, ejection fraction; LV, left ventricle; LVAD, left ventricular assist device; MACE, major adverse cardiovascular event; NICM, non-ischaemic cardiomyopathy; NSVT, non-sustained ventricular tachycardia; OHT, orthotopic heart transplant; PPCM, peripartum cardiomyopathy.
