Distinct renal outcomes for transcatheter aortic valve replacement and surgical repair
To the editor,
Aortic stenosis is one of the most common cardiac degenerative valvular diseases with an estimated prevalence of 1.3% in patients aged between 65 and 74 years and 2.8–4.6% in those aged 75 or more [1, 2]. Transcatheter aortic valve replacement (TAVR) has emerged as a viable option for the treatment of patients with aortic stenosis who are not suitable candidates for surgical aortic valve replacement (SAVR). Acute kidney injury (AKI) is considered an established postoperative complication that is associated with a significant increase in the risk of mortality . We sought to explore the available evidence on the risk of AKI after TAVR as compared with SAVR.
We searched the articles cited in PubMed database from years 2000 to 2017 using key words “aortic stenosis” and “transcatheter aortic valve replacement”, and those evaluating the role of TAVR in management of aortic stenosis were reviewed. Randomized controlled trials (RCT) that contained data on comparative impact...
