Coronary Access After Transcatheter Aortic Valve Replacement With Commissural Alignment: The ALIGN-ACCESS Study

Giuseppe Tarantini et al.

Summary: This study investigated the impact of commissural alignment on the feasibility of coronary access after transcatheter aortic valve replacement (TAVR). The results showed that commissural alignment improves the rate of selective coronary access, but aligned supra-annular transcatheter heart valves (THVs) have a higher risk of unfeasible/nonselective coronary access compared to SAPIEN 3 THVs.

Which patients with aortic stenosis should be referred to surgery rather than transcatheter aortic valve implantation?

Stephan Windecker et al.

Summary: Transcatheter aortic valve implantation (TAVI) has become a standard treatment option for patients with severe symptomatic aortic valve stenosis (AS). The selection between TAVI and surgical aortic valve replacement (SAVR) should be made by a multidisciplinary heart team, considering clinical and anatomical factors as well as patient preferences and lifetime management.

Rationale, Definitions, Techniques, and Outcomes of Commissural Alignment in TAVR From the ALIGN-TAVR Consortium

Gilbert H. L. Tang et al.

Summary: Commissural alignment plays a crucial role in transcatheter aortic valve replacement (TAVR) for younger patients. Recent studies have introduced improved techniques and tools for achieving commissural alignment, and further development is needed to refine the design of transcatheter heart valve and delivery systems.

Transcatheter aortic valve implantation in degenerated surgical aortic valves

Giuseppe Tarantini et al.

Summary: Transcatheter aortic valve implantation (TAVI) within failed bioprosthetic surgical aortic valves (valve-in-valve TAVI) is a well-established procedure for high-risk patients needing repeat aortic valve intervention. Challenges in valve-in-valve treatment include malposition, prosthesis-patient mismatch, and coronary obstruction, highlighting the importance of optimal patient selection and preprocedural planning to minimize risks. This review article provides a comprehensive overview of key periprocedural considerations for valve-in-valve TAVI.

Patient-Specific Implantation Technique to Obtain Neo-Commissural Alignment With Self-Expanding Transcatheter Aortic Valves

Gintautas Bieliauskas et al.

Summary: This study investigates a patient-specific implantation technique during TAVR to achieve safe and reproducible neo-commissural alignment of self-expanding transcatheter heart valves. The results suggest that this technique is feasible and safe in achieving optimal commissural alignment during TAVR procedures.
