Beat‐to‐beat variability of ventricular repolarization reveals sex‐specific instability and proarrhythmic risk

The Journal of Physiology, EarlyView.
Abstract figure legend A mechanistic framework linking sex‐dependent dynamical instability to proarrhythmic risk. Sex‐specific human ventricular models show that upstream modulators, including biological sex, hormones, drugs and heart disease, promote steeper APD restitution in female than male and enhance dynamical instability.

Safety and Effectiveness of a High‐Dose, Tailored Tissue Plasminogen Activator Therapy Protocol: A Joint Pediatric Hematology and Cardiac ICU Quality Improvement Initiative Analysis

Pediatric Blood &Cancer, Volume 73, Issue 11, November 2026.
ABSTRACT Background Pediatric thromboembolism is increasingly encountered in critical care. Systemic thrombolysis with tissue plasminogen activator (tPA) facilitates vessel or valve patency, yet pediatric‐specific protocols remain undefined, and safety concerns persist. Objective To evaluate the efficacy and safety of a tailored, prolonged systemic tPA

Sympathetic overactivity in patients with rheumatic mitral stenosis

, 2004
Background: Mitral stenosis may increase sympathetic nervous activity by increasing left atrial pressure and reducing cardiac output. And elevated sympathetic nerve activity may be a risk factor for the development of clinical manifestations of mitral ...

Clinical Features, Treatments, and Outcomes of an International Cohort of 96 Children with Takayasu Arteritis

ACR Open Rheumatology, Volume 8, Issue 11, November 2026.
Objective To characterize the clinical features, treatment, and outcomes of a large, international cohort of childhood‐onset Takayasu arteritis (cTAK). Methods Patients with a diagnosis of cTAK were identified in A Registry of Childhood Vasculitis and divided into subcohorts by era‐of diagnosis: pre‐biologic (PB; 1986–2006), early biologic (EB; 2007 ...

Anesthetic Management of a Patient with Mitral Stenosis Posted for C-Section: A Case Series [PDF]

Rheumatic heart disease is the primary cause of mitral stenosis, which leads to symptomatic pregnancies due to increased blood volume and heart rate. However, neuraxial anesthesia for cesarean delivery can be safely administered to patients with moderate

Comparison Between the Acurate Neo and the Acurate Neo 2 Transcatheter Heart Valve System: Impact of Midframe Under‐Expansion

Catheterization and Cardiovascular Interventions, Volume 108, Issue 5, Page 1784-1794, November 1, 2026.
ABSTRACT Background Transcatheter aortic valve implantation (TAVI) with the Acurate Neo has been linked to a significant incidence of paravalvular leakage (PVL), addressed by the Acurate Neo 2 incorporating an active sealing skirt. Recent findings suggest that midframe under‐expansion is associated with worse outcomes.

A Large Retrospective Study to Evaluate Utility of Zephyr Covered Stent in Transcatheter Closure of Sinus Venosus Defects

Catheterization and Cardiovascular Interventions, Volume 108, Issue 5, Page 1808-1817, November 1, 2026.
ABSTRACT Background Transcatheter closure (TCC) of sinus venosus defects (SVD) using balloon‐expandable covered stents is an emerging alternative to surgery. ZephyrCS (Sahajanand Laser Technologies, Gandhinagar, India) is available in long lengths to suit SVD closure.

Development of a Severe Mitral Valve Stenosis Secondary to the Treatment of Mitral Regurgitation with a Single MitraClip

, 2016
We report a patient with class III heart failure symptoms due to mitral regurgitation (MR) subsequent to nonischemic cardiomyopathy. The patient underwent percutaneous transcatheter mitral valve repair using a single MitraClip, which reduced the MR ...

Acute Angina in Anomalous Left Main Coronary Artery With Prepulmonic Course: A Case Report

Clinical Case Reports, Volume 14, Issue 11, November 2026.
ABSTRACT Although a prepulmonic left main coronary artery is usually considered a lower‐risk AAOCA subtype, it may still be associated with acute ischemic symptoms when significant atherosclerotic coronary artery disease is present. Multimodality imaging is essential for defining the coronary anatomy, and coronary artery bypass grafting may be the ...
