Transcatheter management of residual mitral regurgitation after transcatheter edge-to-edge repair: a systematic review.
Cardiovasc Interv Ther
January 2025
Heart Valve Center, IRCCS San Raffaele, Milan, Italy.
Background: Treatment of residual mitral regurgitation (MR) with different percutaneous devices after transcatheter edge-to-edge repair (TEER) has been reported as an alternative option to reclipping or surgery. This review aims at describing the different transcatheter strategies available and their results when managing residual MR after TEER.
Methods: A literature search was undertaken across Pubmed, ScienceDirect, SciELO, DOAJ, and Cochrane library databases, to identify article reporting patients with post-TEER residual MR managed by a transcatheter approach that did not involve only the implantation of new clips.
Indoxyl Sulfate Induces Ventricular Arrhythmias Attenuated by Secretoneurin in Right Ventricular Outflow Tract Cardiomyocytes.
Cardiovasc Toxicol
January 2025
Graduate Institute of Clinical Medicine, College of Medicine, Taipei Medical University, No. 250, Wuxing St., Taipei, 11031, Taiwan.
Ventricular arrhythmias (VAs) are major causes of sudden cardiac death in chronic kidney disease (CKD) patients. Indoxyl sulfate (IS) is one common uremic toxin found in CKD patients. This study investigated whether IS could induce VAs via increasing right ventricular outflow tract (RVOT) arrhythmogenesis.

Department of Diagnostic Radiology, Graduate School of Medical Sciences, Kumamoto University, 1-1-1 Honjo, Chuo-ku, Kumamoto, 860-8556, Japan.
Objectives: There is limited evidence of the pericoronary fat attenuation index (FAI) as an imaging marker to assess cancer therapy-related cardiovascular toxicity. We aimed to measure FAI in four consecutive coronary CT angiography (CTA) scans before and 3, 6, and 12 months after anthracycline treatment in patients with breast cancer to determine trends in dynamic changes in FAI after treatment.
Methods: We performed a post hoc analysis of a prospective study (between August 2019 and July 2020) in which anthracycline-induced myocardial injury was evaluated using cardiac CT.
Left atrial functional impairment as a predictor of atrial fibrillation: insights from cardiac CT.
Eur Radiol
January 2025
Rappaport Faculty of Medicine, Technion - Israel Institute of Technology, Haifa, 3525422, Israel.
Objectives: A strong association exists between left atrial (LA) structural remodeling and the development of atrial fibrillation (AF). The role of LA function in AF prediction remains unclear. We studied the relationship between LA function and incident AF using cardiac CT.

Sci Rep
January 2025
School of Engineering, The University of Manchester, Manchester, UK.
This study examines how heart rate (HR) affects hemodynamics in a South African infant with Coarctation of the Aorta. Computed tomography angiography segments aortic coarctation anatomy; Doppler echocardiography derives inlet flow waveforms. Simulations occur at 100, 120, and 160 beats per minute, representing reduced, resting, and elevated HR levels.
