Comparative outcomes of balloon-expandable versus self-expanding transcatheter aortic valves: insights from a large-scale German registry.
BACKGROUND: While transcatheter aortic valve replacement (TAVR) has become an established alternative to surgical aortic valve replacement (SAVR), the comparative outcomes of balloon-expandable (BE) a...
Development and Validation of an Extended Risk Model for Secondary Surgery Following Repair of Discrete Membranous Subaortic Stenosis in Pediatric Patients.
BACKGROUND: Long-term outcomes remain heterogeneous for patients with discrete membranous subaortic stenosis who underwent surgical repair. We aim to develop and validate an extended risk model for pr...
Systemic Inflammation and Outcomes After Mitral Edge-to-Edge Repair: Insights From the OCEAN-Mitral Registry.
BACKGROUND: Systemic inflammation is increasingly recognized as an important contributor to cardiovascular outcomes. High-sensitivity CRP (C-reactive protein) is an established biomarker, but its prog...
RE-LOCK and TRACK: A Reproducible Minimally Invasive Repair for Bileaflet Mitral Disease.
Complex bileaflet and Barlow-type degenerative disease remains among the most demanding substrates in reconstructive mitral surgery, and a right mini-thoracotomy amplifies every source of intraoperati...
Cardiac Myxoma Originating From the Septal Papillary Muscle of the Right Ventricle in a Second-Trimester Patient.
This case illustrates a large right ventricular myxoma causing severe right ventricular outflow tract obstruction. Multimodality imaging, including echocardiography and CT, guided the diagnosis. The p...
Trends and Outcomes of Antithrombotic Strategies for Valve-in-Valve TAVR: The STS/ACC TVT Registry.
BACKGROUND: The optimal antithrombotic strategy after valve-in-valve (ViV) transcatheter aortic valve replacement (TAVR) for degenerated aortic bioprostheses remains undetermined, and current practice...
Proteomic Profiling of RHD-Related Mitral Annulus Calcification Enabled by Magnetic Carbon Nanomaterial-Supported Quasi-Immobilized Enzyme Digestion.
Elucidating the mechanisms underlying rheumatic heart disease (RHD) accompanied by mitral annulus calcification (MAC) facilitates the identification of sensitive diagnostic biomarkers and the developm...
Endoscopic Minimally Invasive Beating-Heart Tricuspid Valve Surgery Without Jugular Vein Cannulation or Caval Snaring: Clinical Outcomes Using Novel Percutaneous Venous Cannulation.
Background and Objectives: Endoscopic beating-heart tricuspid valve (TV) surgery is increasingly adopted in cardiac surgery due to its association with improved postoperative recovery. Conventional ap...
Comparison of Clinical Outcomes of Myval vs. Acurate Neo Valves in TAVR: A Single-Center Experience.
Background and Objectives: Transcatheter aortic valve replacement (TAVR) has become an established treatment for severe symptomatic aortic stenosis, and continuous technological advances have led to t...
Refined Carbohydrate-Rich Diet Promotes Early Myocardial Dysfunction Associated with Adiponectin Reduction, Inflammation, and Impaired Ca(2+) Handling in Female Rats.
Introduction: Diets rich in refined carbohydrates are associated with cardiometabolic dysfunction, but the mechanisms linking metabolic disturbances to myocardial impairment in females remain unclear....
Transcatheter aortic valve implantation outcomes by patient age and sex in COMPARE-TAVI 1: a cohort study.
OBJECTIVES: To explore the outcomes among patients treated with TAVI (transcatheter aortic valve implantation) in the COMPARE-TAVI 1 trial by age groups and sex. DESIGN: Cohort study. SETTING: Three D...
Incidence and risk factors for permanent pacemaker implantation following aortic root surgery.
BACKGROUND: Permanent pacemaker implantation (PPI) remains a serious complication following aortic root replacement (ARR) and valve-sparing root replacement (VSRR). This is due to the proximity of the...
Prognostic Value of the Meta-Analysis Global Group in Chronic Heart Failure Risk Score in Patients Undergoing Mitral Valve Transcatheter Edge-to-Edge Repair.
BACKGROUND: The prognostic value of the Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC) score in patients undergoing mitral valve transcatheter edge-to-edge repair (M-TEER) remains unclea...
Diagnostic and Prognostic Utility of Mitral Annular Plane Systolic Excursion: A Systematic Review and Meta-Analysis.
BACKGROUND: Movement of the mitral annulus toward the left ventricular (LV) apex during systole, termed atrioventricular plane displacement or mitral annular plane systolic excursion (MAPSE), was firs...
Left atrial remodelling and diastolic unloading after transcatheter tricuspid repair.
BACKGROUND AND AIMS: Severe tricuspid regurgitation (TR) alters ventricular interaction and left-sided filling dynamics. However, the longitudinal effects of transcatheter tricuspid edge-to-edge repai...
