Assessment of chronical total occlusions management in France: The ENCOCHE Registry, a prospective, multicentric study.

Background: Coronary chronic total occlusions (CTO) are frequent, and coronary angioplasty has been increasingly used in recent years for lesion revascularisation. However, to date, no dedicated multicentric prospective study is available in France.

Aim: To describe the characteristics of CTO patients and to assess current treatment strategies in French catheterisation laboratory practice.

Circumflex distortion following mitral valve repair.

Mitral valve repair or replacement poses a potential risk of injury to the left circumflex coronary artery (LCx). Such injuries can arise from either direct LCx injury caused by encircling or transfixing stitches, or indirect occlusion resulting from the distortion of adjacent tissues. We provide and illustrate a representative image depicting LCx distortion.

Association Between Aortic Wall Thrombus and Thromboembolic Events After Transfemoral Transcatheter Aortic Valve Replacement.

Background: Thromboembolic events, particularly strokes, remain a major complication of transcatheter aortic valve replacement (TAVR). Embolic protection devices have failed to show significant clinical benefit in large randomized clinical trials. Aortic wall thrombus (AWT) is often observed on multidetector computed tomography during TAVR work-up, but its prognostic significance is uncertain.

What's Next for First Row Fluorometallacycles?

Hydrocarbon-derived metallacycles have been identified as key intermediates in a host of catalyzed transformations of unsaturated organic substrates. In contrast, our knowledge of analogous reactivity of fluorometallacycles is underdeveloped and largely confined to first row metals. Our summary of recent advances aims to inform young investigators of the exciting challenges offered by this pursuit.
