Application of transcatheter aortic valve replacement in elderly patients with native pure aortic regurgitation / 中国医师杂志

ABSTRACT

Objective:This study sought to investigate the feasibility, anatomical indications and operating points of transcatheter aortic valve replacement (TAVR) procedure in the treatment of pure aortic regurgitation (AR).Methods:The medical records of 4 elderly patients with pure AR who were treated in the cardiology department, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from March 2020 to March 2021 were retrospectively analyzed. All patients were implanted with self-expandable valve stents via peripheral artery approach for TAVR treatment. The feasibility, anatomical indications and key points of TAVR were analyzed.Results:The 4 patients with pure AR who were carefully screened had an average age of 66 years, and all achieved TAVR treatment success without serious perioperative complications and death. Postoperative examination and follow-up data showed that cardiac functions and cardiac remodeling indexes were significantly improved.Conclusions:This exploratory study shows that TAVR is technically feasible and effective treatment option for selected elderly patients with native pure AR, which is worthy of further study.
