TAVI in porcelain aorta patients avoids aortic manipulation and shows a consistent trend toward lower neurological risk than surgery, despite limited observational data.
Does transcatheter aortic valve implantation reduce neurological and procedural hazards compared to surgical aortic valve replacement in younger and low-risk patients with porcelain aorta?
In younger and low-risk patients with porcelain aorta, TAVI is frequently favored over surgery to minimize ascending aortic manipulation and mitigate neurological hazards, though lifetime management principles must be considered.
Background and Objectives: Porcelain aorta is an anatomy-driven high-risk phenotype characterized by extensive calcification of the ascending aorta, which complicates surgical aortic valve replacement by increasing embolic and technical hazards during cannulation and cross-clamping. As transcatheter aortic valve implantation (TAVI) expands into younger and low-surgical-risk populations, porcelain aorta creates a distinct clinical dilemma: optimizing short-term procedural safety while ensuring durable long-term outcomes and preserving future treatment options. Materials and Methods: We performed a targeted literature search of MEDLINE/PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL), with the last search conducted on 31 January 2026. We synthesized contemporary clinical evidence on TAVI in patients with imaging-defined porcelain aorta, focusing on neurological outcomes, procedural strategies to reduce embolic risk, access considerations, valve performance, cerebral embolic protection, and implications for lifetime valve management (including coronary access and feasibility of future valve-in-valve interventions). Results: The evidence base specific to porcelain aorta in the contemporary TAVI era is limited and largely observational. Across published cohorts, TAVI avoids direct ascending aortic cannulation and cross-clamping and is generally associated with favorable early safety, with a recurring directional signal toward lower neurological risk compared with surgical strategies that require manipulation of a severely calcified ascending aorta. Interpretation is constrained by heterogeneity in porcelain-aorta definitions, patient selection, valve platforms and access routes, as well as, variability in neurological endpoint definitions and adjudication. Conclusions: In patients with porcelain aorta, TAVI is frequently favored because it minimizes ascending aortic manipulation and may mitigate neurological and procedural hazards. In younger and low-risk patients, Heart Team decision-making should incorporate lifetime management principles, including access planning, preservation of future coronary access, and procedural strategies to reduce embolic risk (with consideration of cerebral embolic protection when appropriate).
