We present a case of transcatheter valve-in-valve replacement performed because of structural valve deterioration of a subcoronary implanted stentless aortic bioprosthesis. A 23-mm self-expandable transcatheter heart valve (THV) with supraannular seating was chosen. The procedure was performed with the patient under conscious sedation. After anchoring and partial valve deployment, the patient experienced an acute onset of angina. The angiogram showed left main coronary artery obstruction. Prompt resheathing and retrieval of the THV was performed, and the procedure was aborted. Subsequently, an open-heart redo operation was performed by the use of a sutureless aortic bioprosthesis, with satisfactory hemodynamic and clinical results.

Prevalence of pulmonary hypertension and associated factors among rheumatic heart disease patients in Ethiopia.

Department of Internal Medicine, Collage of Medicine and Health Science, Debre Markos University, Debre Markos, Ethiopia.
Background: In developing countries evidences regarding pulmonary hypertension (PH) in rheumatic heart disease (RHD) patients are lacking, despite being responsible for significant morbidity and mortality. As a result, identifying the factors that influence PH is crucial to improve the quality of care.
Objective: To determine prevalence of pulmonary hypertension and its associated factors among rheumatic heart disease patients at the public hospitals of Bahir Dar city, Ethiopia.
Transcatheter edge-to-edge repair in severe mitral regurgitation following acute myocardial infarction - aetiology-based analysis.

Aims: To evaluate the association between transcatheter edge-to-edge repair (TEER) and outcomes in patients with significant mitral regurgitation (MR) following acute myocardial infarction (MI), focusing on the aetiology of acute post-MI MR in high-risk surgical patients.
Methods And Results: The International Registry of MitraClip in Acute Mitral Regurgitation following Acute Myocardial Infarction (IREMMI) includes 187 patients with severe MR post-MI managed with TEER. Of these, 176 were included in the analysis, 23 (13%) patients had acute papillary muscle rupture (PMR) and 153 (87%) acute secondary MR.
Analysis of the haemodynamic changes caused by surgical and transcatheter aortic valve replacements by means fluid-structure interaction simulations.

Aortic valve replacements, both surgical and transcatheter, are nowadays widely employed treatments. Although clinically effective, these procedures are correlated with potentially severe clinical complications which can be associated with the non-physiological haemodynamics that they establish. In this work, the fluid dynamics changes produced by surgical and transcatheter aortic valve replacements are analysed and compared with an ideal healthy native valve configuration, employing advanced fluid-structure interaction (FSI) simulations.

Background And Objective: In clinical practice, valve-sparing aortic root replacement surgery primarily addresses left ventricular dysfunction in patients due to severe aortic regurgitation, but there is controversy regarding the choice of surgical technique. In order to investigate which type of valve-sparing aortic root replacement surgeries can achieve better blood flow conditions, this study examines the impact of changes in the geometric morphology of the aortic root on the hemodynamic environment through numerical simulation.
Methods: An idealized model of the aortic root was established based on data obtained from clinical measurements, including using the model of the aortic root without significant lesions as the control group (Model C), while using surgical models of leaflet reimplantation with tubular graft (Model T), leaflet reimplantation with Valsalva graft (Model V), and the Florida sleeve procedure (Model F) as the experimental groups.
Heyde's Syndrome Manifesting as Recurrent Gastrointestinal Bleeding After Valve Replacement.
Cureus
December 2024
Internal Medicine, Hospital Universitario Dr. José Eleuterio González, Monterrey, MEX.
Heyde's syndrome is a clinical entity that combines aortic stenosis, gastrointestinal angiodysplasia, and an acquired von Willebrand factor disorder. This syndrome is characterized by the association between aortic stenosis and recurrent gastrointestinal bleeding episodes, typically linked to angiodysplasias. Effective treatment requires addressing the underlying condition, specifically aortic stenosis, which leads to the structural destruction of coagulation proteins, resulting in the acquired von Willebrand factor disorder and perpetuating the bleeding.
