ABSTRACT
Background: The transcatheter aortic valve replacement (TAVR) has recently gained traction as a viable alternative to surgical aortic valve replacement (SAVR), but data on its safety and clinical outcomes in transplant patients are limited.Methods: We retrieved relevant demographic and clinical outcome data from the U.S. National Inpatient Sample (NIS) for the year 2012-2015. The clinical outcomes of TAVR in renal transplant (RT) and liver transplant (LT) were ascertained using an adjusted odds ratio (aOR) with a 95% confidence interval (CI) on Mantzel-Hensel test.Results: A total of 62,399 TAVR patients were identified; 62,180 (99.6%) with no history of transplant, 219 (0.4%) with RT and 85 (0.1%) with LT. There was no significant difference in odds of in-hospital mortality (OR 0.61, 95% CI 0.25-1.5, p = 0.37), major cardiovascular, respiratory or neurological complications in patients with and without RT. Similarly, the odds of cardiac complications, renal and neurological complications between patients with and without LT were identical.Conclusion: Compared to non-transplant patients, TAVR appears to be associated with similar odds of major systemic complications or mortality in patients with a history of kidney or liver transplant.
