Article Synopsis
- * A total of 22 patients, primarily elderly males with a mean age of 71.7 years, underwent the LBBP procedure, achieving an 86% success rate in lead implantation without major complications.
- * The findings indicate that the Agilis HisPro™ catheter, paired with the Tendril STS Model 2088TC lead, is a promising and safe method for performing LBBP.
A patient with permanent atrial fibrillation, triple mechanical prosthetic valve replacements, and nonischemic cardiomyopathy presented with symptomatic high-grade atrioventricular block. A transvenous implantable cardioverter-defibrillator system was achieved with the defibrillator lead and bipolar pace-sense lead in separate anterolateral branches of the coronary sinus with successful defibrillation testing.

Objectives: We evaluated whether the predictive value of Tpe for SCA improves with heart rate correction and sought to determine an optimal cutoff value for Tpec in the context of SCA risk.
Introduction: Remote monitoring of cardiac implantable electronic devices (CIED) has been shown to improve patient safety and reduce in-office visits. We report our experience with remote monitoring via the Medtronic CareLink(®) network.
Methods: Patients were followed up for six months with scheduled monthly remote monitoring transmissions in addition to routine in-office checks.
Introduction: Improvements in risk stratification for sudden cardiac arrest (SCA) will require discovery of markers that extend beyond the LV ejection fraction (LVEF). The frontal QRS-T angle has been shown to predict risk of SCA but the value of this marker independent of the LVEF has not been investigated.
Methods And Results: Cases of adult SCA with an archived electrocardiogram (12-lead ECG) available before the event, with a computable frontal QRS-T angle, were identified from the Oregon Sudden Unexpected Death Study (Oregon SUDS) ongoing in the Portland, Oregon metro area.
