Abstract

Background: Transcatheter aortic valve implantation (TAVI) is an alternative treatment for surgically high-risk patients with severe aortic stenosis (AS). This study aimed to assess the echocardiographic outcomes of TAVI in patients with severe AS, focusing on left ventricular mass, volume, and pressure.

Methods: This retrospective, registry-based, single-center study was conducted at King Salman Heart Center, Riyadh, Saudi Arabia. We included 200 adult patients who underwent the TAVI procedure and completed at least one year of clinical and echocardiographic follow-up. Baseline demographic, clinical, and echocardiographic data were collected and paired pre- and post-procedure echocardiographic measurements were analyzed.

Result: Paired analysis in comparison of pre and post-transcatheter aortic valve implantation (TAVI) shows significant improvement in left ventricular (LV) mass, volume, and pressure.

Conclusion: This study demonstrates that transcatheter aortic valve implantation (TAVI) leads to significant improvement in key echocardiographic parameters such as left ventricular (LV) size, functions, mass, and ejection fractions (EF).

经导管主动脉瓣植入术（TAVI）对左心室质量、容量和压力的影响。单中心超声心动图分析。

背景：经导管主动脉瓣植入术（TAVI）是外科高危严重主动脉瓣狭窄（AS）患者的替代治疗方法。本研究旨在评估严重AS患者TAVI的超声心动图结果，重点关注左心室质量、体积和压力。方法：这项回顾性、基于登记的单中心研究在沙特阿拉伯利雅得的萨勒曼国王心脏中心进行。我们纳入了200名接受TAVI手术并完成至少一年临床和超声心动图随访的成年患者。收集基线人口统计学、临床和超声心动图数据，并对术前和术后超声心动图测量结果进行配对分析。结果：经导管主动脉瓣植入术（TAVI）前后的配对分析显示，左室（LV）质量、容积和压力均有显著改善。结论：经导管主动脉瓣植入术（TAVI）可显著改善左室（LV）大小、功能、质量和射血分数（EF）等关键超声心动图参数。
