Microscopic Isthmuses and Fibrosis Within the Border Zone of Infarcted Hearts Promote Calcium-Mediated Ectopy and Conduction Block

Frontiers in Physics, 2018
Ventricular tachycardia (VT) secondary to myocardial infarction (MI) remain a major cause of sudden death in adults. Premature ventricular complexes (PVCs), the first initiating beats of a portion of these arrhythmias, arise from triggered activity in ...

A Comprehensive Assessment of Renal Function During and After Pulsed Field Ablation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Acute kidney injury is an uncommon complication of pulsed field ablation (PFA). There is, however, limited empirical data on the dynamics of renal biomarkers apart from creatinine. Furthermore, no study to date has assessed creatinine at more than 24 h after the procedure. Methods Patients undergoing PFA for atrial fibrillation (AF)

Comparison of HEMOlysis Markers Among Three Pulsed Field Ablation Systems: HEMO‐PFA Study

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Pulsed field ablation (PFA) has emerged as a novel non‐thermal modality for atrial fibrillation (AF) ablation. While hemolysis is a known complication of PFA, comparative data among different systems remain limited. Methods We prospectively enrolled 150 consecutive AF patients undergoing ablation with one of three PFA systems ...

Changes in the Type I Collagen mRNA Expression in the Isthmus During the Passage of Egg Through the Oviduct in Japanese Quail

The Journal of Poultry Science, 2003
Type I collagen is one of the major components contained in the eggshell membrane. The aim of this study was to determine whether the expression of type I collagen mRNA is changed during the passage of the egg through the oviduct in Japanese quail ...

Reproductive physiology of the female cat [PDF]

, 2003
Ovarian cyclicity induces considerable changes in morphology, physiology and function of the reproductive organs in animals. This thesis aimed to study reproductive physiology of the female domestic cat, focusing on the cervix, uterus and uterine tube ...

Dominant Frequency Mapping as a Functional Tool for Substrate‐Guided Ventricular Tachycardia Ablation

Journal of Cardiovascular Electrophysiology, EarlyView.
Stimulus‐independent DF mapping integrates intracardiac signals with 3D anatomy to visualize high‐DF activity, with regions derived from SmartTouch and Pentaray catheters showing spatial correspondence with operator‐defined ablation sites. Quantitative analysis demonstrates higher proximity scores at ablation sites, low projection error, and good ...

Oceanscape as Landscape

Landscape Review
‘Landscapes are part of who we are. They are natural systems of which we depend, how we live with our land, and the meaning and pleasure we take from them and our surroundings. They are part of our identity. Landscapes are important to us all’.

Thyroid anomalies with its embryological and clinical correlation

CHRISMED Journal of Health and Research, 2015
Objective: Thyroid gland is the first endocrine gland to start developing in the embryo. It is well-known for its developmental anomalies such as persistence of pyramidal lobe, thyroglossal duct, agenesis of isthmus, agenesis or hemiagenesis of thyroid ...

Prospective Trial of Radiofrequency Catheter Ablation of High Dominant Frequencies After Pulmonary Vein Isolation in Non‐Paroxysmal Atrial Fibrillation (PAD‐AF Trial): A Multicenter, Randomized Clinical Trial

Journal of Cardiovascular Electrophysiology, EarlyView.
In persistent AF, adjunctive dominant frequency‐guided ablation after pulmonary vein isolation did not significantly improve outcomes. Limited overlap between high‐frequency sites and low‐voltage areas suggests functional–structural dissociation, while right atrial low‐voltage burden predicts recurrence.
