Electrophysiological study with endocardial electroanatomic voltage mapping may be utilized to further stratify the risk of sudden cardiac death in patients with cardiac amyloidosis being considered for ICD placement.
Patients with cardiac amyloidosis (CA) have an increased risk of sudden cardiac death. (SCD). However, the role of an implantable cardioverter-defibrillator in the primary prevention of SCD in this group of patients is still controversial. We present a case with CA with recurrent syncope and non-sustained ventricular tachycardia. In order to further stratify the risk of SCD, an electrophysiological study with endocardial electroanatomic voltage mapping was performed prior to the ICD placement.
