Utility of 30-Day Continuous Ambulatory Monitoring to Identify Patients With Delayed Occurrence of Atrioventricular Block After Transcatheter Aortic Valve Replacement.

Background: Mechanical injury in the conduction system requiring permanent pacemaker (PPM) associated with transcatheter aortic valve replacement (TAVR) procedure is a common complication. The objective of this study was to use ambulatory monitor BodyGuardian to assess late occurrence of atrioventricular block (AVB) after TAVR.

Methods: This prospective study evaluated 365 patients who underwent TAVR at Mayo Clinic, Rochester, Minnesota between June 2016 and August 2017.

Effect of ventricular pacing lead position on tricuspid regurgitation: A randomized prospective trial.

Background: Pacing lead-related tricuspid regurgitation (TR), a recognized complication of ventricular pacing lead implantation, may be affected by lead position or diameter.

Objective: This study sought to determine the effect of ventricular pacing lead position and diameter on pacing lead-related TR.

Methods: A randomized prospective trial compared pacing leads in the right ventricular apex (RVA), right ventricular septum (RVS), or left ventricle via the coronary sinus (LV-CS) in a 1:1:1 fashion.

Remote ischemic preconditioning immediately before percutaneous coronary intervention does not impact myocardial necrosis, inflammatory response, and circulating endothelial progenitor cell counts: a single center randomized sham controlled trial.

Aims: Percutaneous coronary intervention (PCI) is frequently accompanied by myocardial injury. The present study was performed to determine whether remote ischemic preconditioning (IP) induces cardioprotection during PCI.

Methods: We enrolled 95 patients requiring nonemergency PCI for stable disease or unstable angina into this prospective clinical trial.
