Cardiac resynchronization therapy (CRT) using a biventricular pacemaker is an invasive and expensive treatment option for left ventricular mechanical dyssynchrony (LVMD). The CRT candidate selection is a crucial issue due to the unreliability of the current standard CRT indicators. Real-time three-dimensional (3-D) echocardiography (RT3DE) provides(More)
A 24-year-old male with Wolff-Parkinson-White syndrome developed systolic cardiomyopathy and severe heart failure following membranous ventricular septal defect repair and tricuspid valve replacement. Following successful catheter ablation of a right anterolateral accessory pathway (AP), complete AV block with junctional escape rhythm was noted. Patient(More)
Introduction: Atrioventricular (AV) nodal ablation performed during pacemaker or ICD implantation for management of atrial tachyarrhythmias. The ablation performed normally from the femoral vein while the device placed via the axillary or cephalic vein approach. Objective: To improve patient safety, satisfaction, and outcomes, we performed AV nodal ablation(More)
BACKGROUND Venous stenosis is a common complication of transvenous lead implantation, but the risk factors for venous stenosis have not been well defined to date. This study was designed to evaluate the incidence of and risk factors for venous stenosis in a large consecutive cohort. METHODS AND RESULTS A total of 212 consecutive patients (136 male, 76(More)
