Revision of subcutaneous implantable cardioverter defibrillator to intermuscular pocket to prevent inappropriate shocks.

Sensing and defibrillation threshold for a S-ICD are impacted by positioning at implant or revision. The intermuscular pocket prevents device migration and provides appropriate, stable sensing vectors.

An Extrapericardial Minimally Invasive Approach for Implantable Cardioverter Defibrillator.

The indications for placement of an implantable cardioverter defibrillators (ICDs) have greatly expanded over the last years. However, standard transvenous approach is not suitable for a subset of patients who cannot benefit from ICD therapy. Here, we have demonstrated the feasibility and efficacy of extrapericardial ICD placement through a minimally invasive access in intact hearts as well as in postmyocardial infarction large animal models.

Recovery of self-reported functional capacity after coronary artery bypass surgery.

Study Objectives: This study was conducted to determine the effects of age, gender, comorbid conditions, and exercise on the recovery of self-reported functional capacity after coronary artery surgery, and to identify predictors of 1-year functional capacity.

Patients: One hundred ninety-eight patients undergoing coronary artery bypass graft surgery.

Measurements And Results: Self-reported functional capacity was evaluated before surgery, and 3 months and 1 year postoperatively using the Veterans Specific Activity Questionnaire (VSAQ).
