Diagnostic Accuracy of Echocardiography and Intraoperative Surgical Inspection of the Unicuspid Aortic Valve.

Unicuspid aortic valve (UAV) is a rare malformation that is often difficult to distinguish from a bicuspid aortic valve (BAV) with commissural fusion by echocardiography or intraoperative surgical inspection. This study assessed the accuracy of intraoperative surgical inspection and two-dimensional echocardiography in diagnosing UAV compared to a gold standard of pathological diagnosis. The Mayo Clinic echocardiographic database, tissue registry database and electronic medical record were searched for all patients assigned a diagnosis of UAV by any technique.

Three Cases of Rare Retroaortic Coronary Anomalies Diagnosed With Angiography and Cardiac CTA.

Coronary artery anomalies are relatively rare (approximately 1% on CTA). We present two exceedingly rare cases, as well as the first reported case of anomalous retro-aortic coronary arteries diagnosed with cardiac CTA and angiography.

Preprocedural Utility of the Echocardiographic Retroaortic Anomalous Coronary Sign.

Imaging series highlighting echocardiographic findings associated with the retroaortic anomalous coronary sign and its utility as a non-invasive modality to recognize technically complex and high-risk retroaortic coronary anomalies prior to intervention.
