Successful Transcatheter Aortic Valve Implantation in High Risk Patients Using the Balloon Expandable Myval Valve

Introduction:

Transcatheter aortic valve implantation (TAVI) has emerged as a breakthrough procedure for treating severe aortic stenosis (AS), particularly in high-risk patients with complex coronary anatomies. A novel solution, the balloon-expandable Myval valve, is proving to be a game-changer. This case report delves into two high-risk patients with low coronary ostial heights and the successful deployment of this advanced valve design.

Summary of Findings:

• Patient Case 1: A 70-year-old female with severe AS, post-SAVR, underwent ViV TAVI with the Myval THV, utilizing a guide extension catheter for coronary protection. The procedure resulted in stable hemodynamics with no complications such as coronary obstruction.
• Patient Case 2: A 63-year-old female with morbid obesity and severe AS received a replacement of her native bicuspid valve. The Myval THV was successfully implanted using a left-sided coronary protection strategy, avoiding coronary obstruction.

Key Findings:

• Innovative Valve Design: The Myval valve’s low frame height and hybrid honeycomb design minimize the risk of coronary occlusion, offering a safer alternative for high-risk TAVI patients.
• Coronary Protection Strategy: Both cases utilized the “wire-only” strategy for coronary protection, emphasizing the importance of pre-procedural planning, particularly in patients with low coronary ostial heights.
• No Coronary Obstruction: Despite high-risk factors, the deployment of the Myval THV was successful in preventing coronary obstruction, showcasing its effectiveness in challenging anatomies.

Integration of External Medical Sources:

According to The American College of Cardiology (ACC), TAVI procedures should be carefully tailored to each patient’s unique anatomical challenges to ensure optimal outcomes. The use of newer-generation valves, such as the Myval THV, can mitigate risks associated with traditional valve designs and improve clinical outcomes in complex cases like the ones presented here.
