Patent ductus arteriosus closure in infants weighing less than 1500 g via a tiny microcatheter: a simple technique with zero-contrast exposure.

Background: Despite patent ductus arteriosus closure in premature infants is a relatively fast procedure, it involves specific steps for equipment exchange and the use of a 4-Fr catheter, which may be large for tiny infants, potentially causing haemodynamic instability or tricuspid valve regurgitation.
Objectives: This study aims to describe the early experience with a new technique designed to simplify transcatheter patent ductus arteriosus closure in premature infants. It enables the closure using the KA micro plug device via a single microcatheter without equipment exchanges and contrast exposure.
Predictive value of CT-based and AI-reconstructed 3D-TAPSE in patients undergoing transcatheter tricuspid valve repair.

Background: The tricuspid annular plane systolic excursion (TAPSE) assessed by echocardiography has failed in predicting outcomes in patients with severe tricuspid regurgitation (TR) undergoing transcatheter tricuspid valve intervention (TTVI). Considering the complex shape of the tricuspid annulus and right ventricle, as well as the difficult echocardiographic image acquisition of the right heart, cardiac computed tomography (CT) might be superior for the analysis of the annular excursion. Thus, this study aimed to analyze whether CT-captured TAPSE provides additional value in predicting outcomes after TTVI.

Objectives: The Ross procedure for aortic regurgitation (AR) and abnormal aortic valve morphologies is associated with an increased risk of autograft dilatation. Autograft support may ameliorate this problem. We analyzed the results for all haemodynamic lesions and the effect of autograft support.

Department of Cardiology, Keio University School of Medicine, Tokyo, Japan.
Background And Aims: The association between periprocedural change in tricuspid regurgitation (TR) and outcomes in patients undergoing mitral transcatheter edge-to-edge repair (M-TEER) is unclear. This study aimed to examine the prognostic value of TR before and after M-TEER.
Methods: Patients in the OCEAN-Mitral registry were divided into four groups according to baseline and post-procedure echocardiographic assessments: no TR/no TR (no TR), no TR/significant TR (new-onset TR), significant TR/no TR (normalized TR), and significant TR/significant TR (residual TR) (all represents before/after M-TEER).
