TAVI vs. SAVR: A Paradigm Shift in Aortic Valve Replacement

The adoption of Transcatheter Aortic Valve Implantation (TAVI) over Surgical Aortic Valve Replacement (SAVR) marks a significant shift in cardiovascular care, driven by minimally invasive techniques, faster recovery, and expanding indications that now extend to younger, low-risk patients. TAVI offers shorter hospital stays, reduced ICU resource use, and a quicker return to daily activities, making it the preferred option for elderly and high-risk patients. Increasing clinical and economic evidence also supports its viability in younger, low-risk populations. As a result, healthcare systems worldwide are redefining treatment pathways to align with these advancements, solidifying TAVI’s role as a preferred approach in aortic valve replacement^1-3.

The Role of Simulation in Optimizing TAVI Outcomes‍

As TAVI adoption increases and patient demographics expand, clinical studies allude that simulation-based training is not just beneficial but a necessary step to ensure procedural success and patient safety. Despite significant advancements in device technology and procedural techniques, TAVI remains operator-dependent, with a well-documented learning curve impacting procedural efficiency, early safety endpoints, and long-term valve performance^4-6. With studies showing that high-volume centers consistently achieve lower complication rates, the need for structured simulation-based training has become paramount⁷.
‍
Understanding the TAVI Learning Curve: What the Data Reveals‍

A multi-center study analyzing over 3,400 TAVI procedures has demonstrated the strong correlation between operator experience and patient outcomes. The study categorized centers into five experience levels—ranging from initial (1–75 cases) to very high (>300cases)—and found a significant reduction in complications and mortality rates as experience increased.

Key findings include:

• 30-day mortality was significantly higher in low-experience centers (9.6% in the initial group, 7.9% in early-stage operators) compared to high-experience centers (3.3%)⁸.
• The early safety endpoint (mortality, stroke, major vascular complications, and surgical conversion) was significantly improved at high-volume centers (27.5% at initial vs. 14.9% at very high experience levels, p < 0.001)⁹.
• Centers performing >100 TAVI cases per year saw a greater than 50% reduction in 30-day all-cause mortality compared to those performing <50 cases annually¹⁰.

These findings highlight the importance of procedural exposure and technical proficiency in navigating complex TAVI procedures. Importantly, simulation-based training provides a structured and scalable, risk-free method for operators to gain experience before real patient cases.

Clinical Impact: How Simulation Enhances TAVI Performance

The implementation of advanced TAVI simulation has been shown to:
✔ Improve procedural accuracy by allowing operators to master cusp overlap technique, commissural alignment, and annular sizing in a controlled setting⁸.
✔ Reduce technical errors associated with misaligned valve positioning, coronary occlusion, and conduction disturbances^9
‍ ✔ Accelerate operator learning by providing real-time hemodynamic feedback and post-procedure assessments¹⁰.
✔ Enhance decision-making by allowing trainees to manage complex anatomy and patient variability across both balloon-expandable and self-expanding valve platforms¹¹.
✔ Standardize TAVI training, ensuring low-volume centers can achieve outcomes comparable to high-volume centers^12.

At leading interventional cardiology conferences such as PCR London Valves, structured simulation training has proven instrumental in preparing operators for real-world TAVI procedures:
‍

"We have used the simulator in multiple sessions at PCR congresses to great effect, where we showcase the latest advancements in interventional cardiology, the Mentice simulator has proven invaluable. It not only integrates all the key principles we teach through other simulators and visual aids but elevates them by providing a unified and comprehensive training experience. This platform uniquely combines tactile feedback, realistic procedural scenarios, and advanced visualization to create a seamless learning experience. By bringing together the full procedural workflow, the simulator ensures that physicians leave with a clear understanding of how to execute the techniques with precision and confidence.”
