Coronary Flow in Hypertrophic Obstructive Cardiomyopathy—Immediate Effects of Alcohol Septal Ablation

Catheterization and Cardiovascular Interventions, Volume 108, Issue 4, Page 1344-1353, October 1, 2026.
ABSTRACT Background Hypertrophic cardiomyopathy is associated with alterations in coronary microvascular function which have variable pathophysiologic mechanisms, and variable reversibility acutely and chronically following alcohol septal ablation (ASA).

Multisystem Complications in Non‐Transfusion‐Dependent β‐Thalassemia Intermedia: A Case Highlighting the Need for Early Intervention

Clinical Case Reports, Volume 14, Issue 10, October 2026.
ABSTRACT This case highlights that severe complications of non‐transfusion‐dependent β‐thalassemia may be preventable with appropriate monitoring and timely intervention; however, once established, multisystem complications can be challenging to treat.

Large Obstructive Left Atrial Myxoma in an Adolescent Girl Presenting With Stroke

Clinical Case Reports, Volume 14, Issue 10, October 2026.
ABSTRACT Pediatric cardiac myxomas are rare but may present with embolic stroke and rapidly progress to life‐threatening hemodynamic obstruction. Ischemic stroke with a suspected embolic source in children should prompt echocardiographic evaluation. Early recognition and urgent surgical management are critical to prevent obstruction, embolization, and ...

Diagnostic Performance of a Deep Learning Model Using Phonocardiogram and Single‐Lead ECG Signals for Detecting Moderate‐or‐Greater Aortic Stenosis: Multicenter External Validation

Clinical Cardiology, Volume 49, Issue 10, October 2026.
In an independent multicenter cohort of 951 patients undergoing echocardiography, a deep learning model analyzing an 8‐s heart sound and ECG recording detected moderate‐or‐greater aortic stenosis with 92.9% sensitivity and 87.9% specificity. This approach may support the decision to refer patients from auscultation to echocardiography.

MODERN METHODS OF MITRAL VALVE PROLAPSE DIAGNOSTICS AND PREVALENCE ASSESSMENT IN YOUNG PEOPLE

Российский кардиологический журнал, 2010
The paper presents echocardiography examination results in healthy young people. The prevalence of classic and nonclassic mitral valve prolapse (MVP) is assessed. The prevalence of primary myxomatous MVP is independent of gender or age, while non-classic

Effect of the Mitral Valve on the Intra Ventricular Hemodynamics

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 10, October 2026.
Patient‐specific Computational Fluid Dynamics was employed to analyze the impact of four distinct mitral valve geometries, varying in area and jet direction, on left‐ventricular flow and overall heart efficiency. The valve design influenced intraventricular vortices, turbulent kinetic energy, and dissipation.
