We present a rare case of a left ventricular pseudoaneurysm following mitral valve repair probably due to testing the valve's competence. The pseudoaneurysm was treated successfully with a sutureless technique in which layers of a biodegradable collagen system with fibrinogen-based coating were used. We reviewed the literature regarding left ventricular rupture following mitral valve surgery published from 1990 until 2006. Overall, the incidence of this complication was 0.56% for 10978 operations, and the mortality rate was 57.4%. We also describe a possible mechanism common to all forms of left ventricular rupture.

Growth Differentiation Factor-15 Is Associated With Congestion-Related Anorexia and Weight Loss in Advanced Heart Failure.
JACC Heart Fail

Institute for Clinical and Experimental Medicine (IKEM), Prague, Czech Republic. Electronic address:
Background: Growth differentiation factor (GDF)-15 is a pleiotropic cytokine that is associated with appetite-suppressing effects and weight loss in patients with malignancy.
Objectives: This study aims to investigate the relationships between GDF-15 levels, anorexia, cachexia, and clinical outcomes in patients with advanced heart failure with reduced ejection fraction (HFrEF).
Methods: In this observational, retrospective analysis, a total of 344 patients with advanced HFrEF (age 58 ± 10 years, 85% male, 67% NYHA functional class III), underwent clinical and echocardiographic examination, body composition evaluation by skinfolds and dual-energy x-ray absorptiometry, circulating metabolite assessment, Minnesota Living with Heart Failure Questionnaire, and right heart catheterization.
Transcatheter Left Ventricular Reconstruction in Heart Failure Patients With Prior Anterior Myocardial Infarction: The Prospective ALIVE Trial.
JACC Heart Fail

The Zena and Michael A. Wiener Cardiovascular Institute, Icahn School of Medicine at Mount Sinai, New York, New York, USA.
Background: Left ventricular (LV) dilatation and extensive scar portend a poor prognosis in heart failure (HF). The Revivent TC system (BioVentrix Inc) is used either during a hybrid transcatheter-surgical or a surgical-only procedure to exclude transmural scar and reduce LV dimensions.
Objectives: The purpose of this study was to examine the safety and efficacy of the Revivent TC® anchor system in patients with HF.
Effect of additional dimensions and views in the echocardiographic determination of 3-dimensional left ventricular volume in myxomatous mitral valve disease in dogs.
J Vet Intern Med
January 2025
Department of Clinical Sciences, College of Veterinary Medicine, Cornell University, Ithaca, New York, USA.
Background: Left ventricular (LV) volumes can be calculated from various linear, monoplane, and multiplane echocardiographic methods, and the same method can be applied to different imaging views. However, these methods and their variations have not been comprehensively evaluated against real-time 3-dimensional echocardiography (RT3D).
Hypothesis/objectives: To identify the LV volumetric approaches that produce the least bias and the best agreement with RT3D, and to assess interoperator reproducibility between an experienced and an inexperienced operator.
Effect of del Nido cardioplegia in patients with reduced left ventricular ejection fraction: A meta-analysis.

Department of Cardiothoracic Surgery, Lankenau Heart Institute, Wynnewood, PA, USA.
Purpose: Research on the safety and efficacy of del Nido cardioplegia in adult patients with reduced left ventricular ejection fraction (LVEF) is limited. We evaluated the effect of del Nido cardioplegia on early outcomes of cardiac surgery in this cohort.
Methods: PubMed, Scopus, and the Cochrane Central Register of Controlled Trials were searched through August 2024 to conduct a meta-analysis comparing del Nido to other cardioplegia in adult patients with reduced LVEF (≤50%).
