ECG-gated CT in Aortic Perivalvular Abscess: Comparison with Transesophageal Echocardiography and Intraoperative Findings

Electrocardiography-gated CT had noninferior sensitivity compared with transesophageal echocardiography in early identification of aortic perivalvular abscesses, extension of these abscesses, fistulization, and valvular destruction but had inferior sensitivity in detecting vegetations.
