The editorial companion framed this as "complications, not rescue" — meaning the CMS volume threshold debate should focus on procedural technique, patient selection, and CT planning, not ICU heroics after things go wrong.

Two adjunct findings sharpen the picture.

A Cureus meta-analysis of 4,828 patients (four studies, all non-randomized) found Abbott's Navitor self-expandable valve tripled moderate-to-severe PVL versus SAPIEN (RR 3.36) and doubled permanent pacemaker rates (RR 2.16), while cutting patient-prosthesis mismatch nearly in half (RR 0.55) — a hemodynamic-versus-complication tradeoff the guidelines don't yet address.

Editor’s take pending for this article; this is the section commentary excerpt.

Source Abstract

The extension of transcatheter aortic valve replacement (TAVR) to younger patients with longer life expectancy has driven a shift in focus toward procedural optimization, with the goals of maximal clinical improvement, durable outcomes, maintained coronary access, and avoidance of permanent pacemaker implantation. A TAVR CODE framework including 4 key fluoroscopic parameters-coaxiality, orientation, depth, and expansion-has recently been proposed to standardize the intraprocedural evaluation of optimal transcatheter heart valve (THV) implantation. Systematic implementation of these concepts during TAVR is expected to improve valve performance and durability. This is hypothesized to improve afterload reduction, enhance left ventricular reverse remodeling, and confer increased and longer lasting clinical benefits. To date, procedural strategies to optimize TAVR outcomes have been largely based upon expert opinion, supported predominantly by mechanistic and retrospective studies. Ongoing randomized trials are evaluating the effects of systematic pre- and postdilatation during TAVR, the impact of same-volume double-tap techniques with balloon-expandable valves, and the effectiveness of different commissural alignment techniques. Meanwhile, intravascular ultrasound is under investigation as a tool to evaluate THV expansion to guide postdilatation, while technical consistency may be improved by innovative THV designs that promote symmetrical expansion, better fluoroscopic visualization, and robotic insertion systems using artificial intelligence. In this article, we detail the possible impact of implementing the TAVR CODE framework on THV function, durability, and clinical outcomes, and provide an expert perspective on procedural strategies to achieve optimal index TAVR outcomes, including management frameworks and position statements according to contemporary best practices.
