*Postintervention T2*CMR was not performed.
†This is defined as the time to death from the beginning of the intervention. All patients died during the postintervention phase.
‡Described as sustained and non-sustained atrial and ventricular tachycardia.
AE, adverse events; T2*CMR, cardiac T2* magnetic resonance imaging; TTE, transthoracic echocardiography.
