NCT03915015
This is a database study of clinically indicated MRIs on patients with permanent pacemakers and implantable cardioverter defibrillators.

Implanted cardiac devices are commonly used to treat a wide variety of heart diseases, including arrhythmias, cardiac resynchronization in select heart failure patients, and life threatening heart rhythms. Approximately 400,000 devices are implanted annually, and more than 3 million patients currently have implanted devices1. Implanted cardiac devices are made to 2 components, the can and the leads. The can contains the electric circuits and the battery, which must be replaced every 5-10 years. The can is connected to external leads which pass through the subclavian vein, and depending on the device, into the vena cava, right atrium, right ventricle, and/or coronary sinus. Leads typically last longer than the battery, and are simply reconnected to a new can at the time of replacement. Certain clinical situations necessitate lead removal, including pocket infection, device related endocarditis, venous stenosis or occlusion with the need for new access, and removal of abandoned or malfunctioning leads. Removing the leads is technically difficult due to fibrosis, and requires specialized equipment. Compared to lead implantation, extraction of leads is relatively rare, with a life time risk of a device patient needing an extraction in the 1-5% range. Given that this is a relatively rare procedure and is only done at a few centers, documentation of our experiences with lead extraction can lead to ongoing improvements in both procedural techniques and outcomes.
NCT06087497
The goal of this study is to understand the effects of early mobilization after a Z stitch procedure in patients undergoing certain heart-related treatments. The investigators want to find out if allowing patients to move around sooner after their procedure can improve their satisfaction and potentially lead to earlier discharge from the hospital. Type of Study: Clinical Trial Participant Population/Health Conditions: Patients aged 18-99 undergoing specific heart procedures such as atrial fibrillation treatment, atrial flutter treatment, supraventricular tachycardia treatment, diagnostic electrophysiology studies, AV node ablation, or Watchman device placement. Main Questions: Does early mobilization (getting up and moving around sooner) after the Z stitch procedure improve patient satisfaction? Participants will be divided into two groups, and researchers will compare those who have one hour of bedrest with those who have four hours of bedrest after the Z stitch procedure. The investigators want to see if the shorter bedrest period leads to higher patient satisfaction.
