Transcatheter Mitral Valve Replacement Using Annular Reduction by Cinching With TEER in the Commissure (ARCTIC).

Background: Mitral annular calcification with valve dysfunction remains a challenging syndrome. Operative risk is high, and available transcatheter therapies are limited.

Methods: This study describes our initial experience with a novel procedure to address large mitral annuli when no surgical or trial-based transcatheter mitral valve replacement device is available.

Novel Transcatheter Approach to Treat Primum Atrial Septal Defects.

•Degenerative common AVC defect can mimic rheumatic MV stenosis.•Closure of primum ASD can be achieved percutaneously.•Live 3D multiplanar TEE is crucial for procedural guidance.

Multimodality Imaging Assessment of Anomalous Aortic Origin of the Left Main Coronary Artery Presenting With Syncope and Non-ST Elevation Myocardial Infarction.

Anomalous aortic origin of a coronary artery (AAOCA) is a rare congenital abnormality associated with myocardial ischemia and sudden cardiac death. We present a case of a 20 year old previously healthy male presenting with exertional syncope and non-ST elevation myocardial infarction. Coronary computed tomography angiography showed an anomalous left main coronary artery arising from the right coronary cusp with a slit-like appearance, acute angle origin, intramural course, and a subsequent inter-arterial course between the main pulmonary artery and the proximal aorta.
