Characterization of maternal mortality in pulmonary hypertension

Patients	Etiology	sPAP (mmHg)	Delivery timing (weeks)	Delivery mode	Anesthesia	Rescue therapy	Timing after delivery	Cause of death
1	PDA	105	34	Urgent cesarean	Epidural-	dopamine + adrenaline  + ventilator	3 days	Severe preeclampsia, heart failure associated with multiple organ failure
2	PDAa	89	35	Urgent cesarean	General-	nitric oxide + epinephrine + dopamine isoproterenol +  norepinephrineventilator + CPR	10 days	Persistent hypoxemia, circulatory collapse and hypoxic encephalopathy
3	VSD	57	33	Urgent cesarean	General-	epinephrine + dopamine + ventilator + CPR	within 24 h	Multiple organ failure, postpartum hemorrhage(1500 ml)
4	ASD	87	38	Urgent cesarean	General-	dopamine + epinephrine  + dopamine + ventilator	10 days	Severe preeclampsia, circulatory collapse, hypoxic encephalopathy
5	VSDb	84	33	Planned cesarean	Epidural-	Nebulized iloprost + Nitric oxide + defibrillation	2 days	Sudden ventricular fibrillation with RV systolic pressure as high as 132 mmHg
