Outcomes of transcatheter aortic valve implantation compared with surgical aortic valve replacement in geriatric patients with chronic kidney disease




Outcomes of transcatheter aortic valve implantation compared with surgical aortic valve replacement in geriatric patients with chronic kidney disease




Clinical Nephrology 90(2): 87-93



Transcatheter aortic valve implantation (TAVI) is a less invasive treatment modality for patients with severe aortic valve stenosis (AS) who are at a higher risk if they have surgery. Preoperative chronic kidney disease (CKD) influences outcomes of cardiac surgery and is associated with a higher mortality and more complicated hospital course. The aims of our study were to evaluate the comparative outcomes of TAVI versus surgical aortic valve replacement (SAVR) in geriatric patients with preoperative CKD. We prospectively collected data on patients > 75 years of age who underwent either SAVR or TAVI at Shaare Zedek Medical Center, Jerusalem, Israel. The outcomes studied were postoperative acute kidney injury (AKI), in-hospital and long-term mortality, and major neurologic and infectious morbidity. A total of 318 patients were analyzed, of those, 199 and 119 underwent SAVR and TAVI, respectively. In patients with CKD, there was no statistically significant difference in postoperative AKI. SAVR patients had significantly higher in-hospital mortality (OR 5.9; 95% CI 1.6 - 29.6, p = 0.02), postoperative infection (OR 4.2; 95% CI 1.6 - 12.4, p = 0.005), and longer duration of hospital stay. Mortality at 1 and 2 years was lower in the SAVR group, although the difference was not statistically significant (p = 0.059). For elderly patients with CKD who are at a higher risk if they have surgery. TAVI offers a good alternative with lower procedural risk.
