Fragmented QRS: Electrophysiological Bases, Pathophysiological Mechanisms, and Clinical Prognostic Significance

Background: Fragmented QRS (fQRS) is characterized by morphological irregularities in ventricular depolarization on a standard 12-lead surface electrocardiogram (ECG) and is considered a non-invasive indicator of myocardial conduction heterogeneity. Microstructural changes such as non-uniform anisotropy, gap junction reorganization, and interstitial fibrosis can disrupt the propagation…

Salvage Superselective Vesical Artery Embolization for Intractable Hematuria Refractory to Conservative and Endoscopic Management: Angiographic Patterns and Short-Term Outcomes by Etiology

Background/Objective: Intractable bladder hematuria may persist despite continuous bladder irrigation and endoscopic hemostasis, exposing frail patients to repeated transfusions and the morbidity associated with urinary diversion or palliative cystectomy. This study evaluated the outcomes and safety of salvage microcatheter-based superselective vesical artery embolization (SVAE) in…

Preoperative TSH Levels as an Adjunctive Risk Factor for Malignancy in Thyroid Nodules: Our Single-Center Experience

Objective: To evaluate the association between preoperative thyroid-stimulating hormone levels and postoperative histopathological malignancy in patients undergoing thyroidectomy for thyroid nodules, and to compare the discriminative performance of thyroid-stimulating hormone with that of the Thyroid Imaging Reporting and Data System score. Material and Methods: A…
