Suggested diagnostic criteria for primary graft failure [7, 9].

Presence of	Evidenced by
Ventricular systolic dysfunction—left, right, or biventricular dysfunction	Echocardiographic evidence of dysfunction
Cardiogenic shock lasting more than one hour	Low systolic blood pressure < 90 mmHg and/or low cardiac output—<2 L/minute/m2 Despite adequate intracardiac filling pressures—CVP > 15 mmHg and/or PAWP > 20 mmHg
Circulatory support	Use of ≥2 inotropic agents/vasopressors including high-dose epinephrine or norepinephrine and/or use of a mechanical assist device—IABP, ECMO, VAD
Appropriate time frame	Onset < 24 hours after transplantation
Exclusion of secondary causes of PGF	For example, cardiac tamponade and hyperacute rejection
