Causes and timing of mortality.

Patient Identifier	Postoperative Day of Death	Cardiac Diagnosis	Procedure	Early Shunt Occlusion	Late Shunt Occlusion	Cause of Death
A	12	HLHS	Norwood / m-BTS	No	Yes	Late shunt occlusion.
B	13	HLHS	Norwood / m-BTS	No	No	Well until POD 13; autopsy suggested acute myocardial infarction.
C	17	Heterotaxy, RVDAVC, dTGA, TAPVR	m-BTS, bilateral PA plasty, TAPRV repair	No	No	Arrested POD 1. Placed on ECMO. Cardiac function remained poor; withdrew care.
D	18	TA, VSD	Norwood / m-BTS	No	Yes	Late shunt occlusion.
E	31	VSD, PS, DORV	m-BTS	No	No	Transfusion reaction POD 0 with associated arrest with significant sequellae; made DNR.
F	131	HLHS	Norwood / m-BTS, PA debanding, bilateral PA plasty	No	No	Micropremature infant. Remained in hospital through Glenn; thrombus in Glenn circuit.

DORV = Double outlet right ventricle; dTGA = Dextro-transposition of the great arteries; DNR = Do not resuscitate; ECMO = Extracorporeal membrane oxygenation; HLHS = Hypoplastic left heart syndrome; m-BTS = modified Blalock-Taussig shunt; PA = Pulmonary artery; POD = Postoperative day; PS = Pulmonary stenosis; RVDAVC = Right ventricle dominant atrioventricular canal; TA = Tricuspid atresia; TAPVR = Total anomalous pulmonary venous return; VSD = Ventricular septal defect
