Staying in the Shallow End: Minimizing Permanent Pacemaker Implantation With a Novel Implantation Method.
Abstract
Although transcatheter aortic valve replacement (TAVR) has expanded the treatment paradigm in patients with symptomatic, severe aortic stenosis, the risk of permanent pacemaker (PPM) implantation has emerged as a clear, known procedural complication following the procedure. The pivotal randomized studies have demonstrated that the risk of PPM is higher with self-expanding valves compared with balloon-expandable valves.1,2 As TAVR utilization increases in younger, lowerrisk patients, it will be challenging to tolerate significantly higher rates of conduction system abnormalities in excess to those observed with surgical aortic valve replacement.
