    Correlations between myocardial injury current and lead performance in His bundle pacing compared with left bundle branch area pacing and right ventricular septum pacing

    Conduction system pacing by implanting the lead in the His bundle (HBP) region or in the left bundle branch area (LBBAP) has gained popularity. Myocardial injury current (IC) is useful for predicting adequate ...

    Pulmonary vein volume and myocardial sleeve extension estimated by 3D computed tomography and voltage map** predict arrhythmogenic triggers of paroxysmal atrial fibrillation

    Relationship between pulmonary vein (PV) anatomy and the pathophysiology of paroxysmal atrial fibrillation (PAF) remains incompletely studied. The aim of this study was to determine whether PV anatomy predicts...

    Inverse Correlation Between Left Atrial Appendage Function and CHA2DS2-VASc Score in Patients with Atrial Flutter

    Impaired left atrial appendage ejection fraction (LAA-EF) and peak LAA flow velocity (LAA-FV) are associated with high thromboembolic risks in patients with atrial fibrillation (AF). Herein, we examined LAA fu...

    Green tea extract given before regional myocardial ischemia–reperfusion in rats improves myocardial contractility by attenuating calcium overload

    There is evidence for a negative correlation between green tea consumption and cardiovascular diseases. The aim of the present study was to examine whether green tea extract (GTE) given before regional myocard...

    Green tea extract protects rats against myocardial infarction associated with left anterior descending coronary artery ligation

    There is increasing evidence that green tea polyphenols can protect against myocardial damage. Recently, we showed that they bind to cardiac troponin C and alter myofilament Ca2+ sensitivity in cardiac muscle. In...

    Pre-Procedure Duplex Ultrasonography to Assist Cephalic Vein Isolation in Pacemaker and Defibrillator Implantation

    Background: Difficulty in isolating the cephalic vein contributes to failed pacemaker and intracardiac cardioverter-defibrillator (ICD) implantation via the cephalic venous approach. The deltopectoral groove is u...

    Feasibility and Accuracy of Pre-procedure Imaging of the Proximal Cephalic Vein by Duplex Ultrasonography in Pacemaker and Defibrillator Implantation

    Background: Failure of the cephalic venous approach in pacemaker and defibrillator implantation is always due to the small size and difficulty in isolation of the cephalic vein. We propose that pre-procedure ima...
