BackgroundBackground
• Based on randomized trials with first generation devices, Based on randomized trials with first generation devices, transcatheter aortic valve replacement (TAVR) has been transcatheter aortic valve replacement (TAVR) has been incorporated into the treatment strategy for high-risk and incorporated into the treatment strategy for high-risk and inoperable patients with severe AS.inoperable patients with severe AS.
• Procedural complications remain a concern with TAVR, Procedural complications remain a concern with TAVR, including stroke, vascular complications, paravalvular leak including stroke, vascular complications, paravalvular leak (PVL) and conduction disturbances.(PVL) and conduction disturbances.
• Addressing these limitations will support TAVR use in Addressing these limitations will support TAVR use in lower risk populations.lower risk populations.
