A Nano‐Interception Strategy for Chronic Heart Failure: Prussian Blue Nanoparticles Disrupt Fibroblast‐Immune Communication via CCL2 Sequestration

Advanced Materials, Volume 38, Issue 31, 2 June 2026.
A nano‐interception strategy disrupts pathogenic fibroblast–macrophage crosstalk in chronic heart failure. Scalable Prussian blue nanoparticles selectively sequester CCL2 via ultrahigh‐affinity binding, preventing CCR2+ macrophage recruitment and breaking a key fibro‐inflammatory circuit. This approach demonstrates robust efficacy in murine and porcine

Around and Through: Successful Mitral Paravalvular Leakage Closure Using Both Anterograde and Retrograde Approaches

Catheterization and Cardiovascular Interventions, Volume 107, Issue 7, Page 2179-2182, June 1, 2026.
ABSTRACT Paravalvular leak (PVL) is a recognized complication after surgical mitral valve replacement and may cause heart failure, pulmonary hypertension, or hemolysis when moderate or severe. Although redo surgery is the definitive treatment, it carries substantial risk in elderly patients or those with multiple prior cardiac surgeries.

Measurement of Atrial Septal Defect Size: A Comparative Study between Transesophageal Echocardiography and Balloon Occlusive Diameter Method

Journal of Tehran University Heart Center, 2010
Background: Transcatheter closure of atrial septal defect secundum (ASD-II) has become an alternative method for surgery. We sought to compare the two-dimensional transesophageal echocardiography (TEE) method for measuring atrial septal defect with ...

Primary Cardiac Angiosarcoma in a Young Male: Rare Presentation With Right Atrial Endocardial Dissection and Right Coronary Artery Tumor Fistula

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT We report the case of a 19‐year‐old man who presented with several months of exertional dyspnea and recent‐onset hemostasis. Initial imaging revealed multiple pulmonary nodules. Days later, he was referred to a specialized center with chest pain and signs of pericarditis.

Atrial Flutter as a Late Presentation of Scimitar Vein in an Adult With Prior ASD Repair

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Adult patients with unexplained atrial arrhythmias and right heart dilation should prompt consideration of congenital anomalies such as scimitar vein, even decades after atrial septal defect repair. Early recognition using multi‐modality imaging may prevent delayed diagnosis and progressive cardiopulmonary complications.

Two Cases of Post‐Operative Coronary–Cameral Fistulas After Unusual Myectomy Procedures

Clinical Case Reports, Volume 14, Issue 6, June 2026.
Post‐surgical coronary–cameral fistulas (CCF) can occur after various myectomy procedures. Here we present one case of CCF after resection of the hypertrophied RV muscle bundle in double‐chambered RV (DCRV) and one case of CCF after subaortic web resection.

“Diagnostic Performance of Artificial Intelligence in Evaluating Tricuspid Regurgitation: A Systematic Review and Meta‐Analysis”

Clinical Cardiology, Volume 49, Issue 6, June 2026.
Artificial intelligence demonstrates strong diagnostic accuracy for detecting tricuspid regurgitation, particularly with echocardiography‐based models. Despite promising performance, substantial heterogeneity and limited external validation highlight the need for prospective, multicenter studies before routine clinical implementation.

Cytologic Findings in Esophageal Perforation: An Institutional Experience With Pleural Fluid Specimens

Diagnostic Cytopathology, Volume 54, Issue 6, Page 429-435, June 2026.
ABSTRACT Introduction Esophageal perforation (EP) is a rare but life‐threatening condition, and most cases are due to iatrogenic causes. The rest occur spontaneously, due to malignancies, or trauma. The mortality rates can approach 50%, and delayed diagnosis of EP exacerbates patient outcomes.
