Utility of Artificial Intelligence Plaque Quantification: Results of the DECODE Study.

Background: Artificial Intelligence Plaque Analysis (AI-QCPA, HeartFlow) provides, from a CCTA, quantitative plaque burden information including total plaque and plaque subtype volumes. We sought to evaluate the clinical utility of AI-QCPA in clinical decision making.

Methods: One hundred cases were reviewed by 3 highly experienced practicing cardiologists who are SCCT level 3 CCTA readers.

Recipient atrial flutter masquerading as donor flutter in a heart transplant recipient.

Atrial flutter is common after orthotopic heart transplantation. We present the case of a patient who presented with atrial flutter on 12-lead electrocardiogram. On invasive electrophysiologic study, the donor heart was found to be in sinus rhythm and the recipient atrium was in flutter, which was dissociated from the donor.
