Transcatheter aortic valve replacement (TAVR) was first introduced as a minimally invasive treatment for patients with severe aortic stenosis (AS) who are at high or intermediate surgical risk. Recently, its application has expanded to include younger and lower-risk patients, establishing TAVR as a less invasive alternative to surgical aortic valve replacement (SAVR) across the entire surgical spectrum. The expanding utilization of TAVR has driven significant advancements that have greatly enhanced its safety and effectiveness, resulting in a substantial reduction in complications such as paravalvular leak, conduction abnormalities, and periprocedural strokes. Numerous trials have demonstrated the potential superiority of TAVR over conventional surgery in achieving favorable clinical outcomes. Furthermore, the increasing number of long-term trials has provided valuable insight into TAVR outcomes in previously under-studied populations, including patients with complex anatomies. However, significant challenges remain, particularly in ensuring the long-term durability of transcatheter valves, with younger patients likely to outlive their bioprosthetic valves. Consequently, the focus is shifting towards lifetime management strategies, including considerations for coronary re-access, the risk of coronary obstruction, and prosthesis-patient mismatch. This review explores key developments in the field, including TAVR for aortic regurgitation and bicuspid anatomy, the emerging role of TAVR in moderate and asymptomatic AS, and innovations in valve design and procedural planning. We also examine novel imaging tools, adjunctive technologies, and strategies to address coronary access and re-intervention. As long-term data accumulate, these evolving trends will shape the future of TAVR and its role in managing aortic valve disease across increasingly complex clinical scenarios.
