Frontal Plane QRS-T Angle as a Marker of Cardiac Iron Overload in Patients with Beta Thalassemia Major.

Introduction: Cardiomyopathy due to myocardial iron deposition is the leading cause of death in transfusion- dependent beta-thalassemia major (β-TM) patients. Although cardiac T2* magnetic resonance imaging (MRI) can be used for the early detection of cardiac iron level before the onset of symptoms associated with iron overload, this expensive method is not widely available in many hospitals. Frontal QRS-T angle is a novel marker of myocardial repolarization and is associated with adverse cardiac outcomes.

Usefulness of the systemic immune-inflammation index in predicting atrial fibrillation recurrence after direct current cardioversion.

We aimed to determine whether there is a relationship between the systemic immune-inflammation (SII) index and the recurrence of atrial fibrillation (AF) after successful direct current cardioversion (DCCV). The study included 99 patients with persistent AF who underwent successful cardioversion between 2015 and 2020. In multiple regression analyses, the SII index was found to be a better independent predictor of AF recurrence after successful DCCV (p < 0.

Asymptomatic Cerebral Emboli Following Carotid Artery Stenting: A Diffusion-Weighted MRI Study.

Background: Silent cranial embolism due to carotid artery stenting has been demonstrated to cause dementia, cognitive decline, and even ischemic stroke. The purpose of this study was to compare the periprocedural asymptomatic cranial embolism rates of different stent designs used for extracranial carotid stenosis with diffusion-weighted magnetic resonance imaging.

Methods: A total of 507 consecutive patients who underwent carotid artery stenting at our center from December 2010 to June 2020 (mean age, 66.
