Introduction: Chest radiotherapy has been utilized to treat intra-thoracic and mediastinal tumors. Chest wall irradiation (C-XRT) survivors frequently develop valvular disease, including aortic stenosis, which eventually requires valve replacement. Previous trials have shown worse outcomes with surgical aortic valve replacement. However, transcatheter aortic valve replacement (TAVR) outcomes-related data in patients with C-XRT is limited., Methods: The national inpatient sample (NIS) database was queried from 2016 to 2020 to identify adult hospitalizations with TAVR, which were dichotomized based on a history of C-XRT using ICD-10-CM codes. Propensity score matching was performed to derive age, sex, hospital characteristics, and co-morbidities matched controls without a history of C-XRT. The outcomes studied were inpatient mortality and complications, mean length of stay (LOS), and total hospital charge (THC). Multivariate logistic and linear regression were used to analyze the outcomes., Results: Of 296,670 patients who underwent TAVR between 2016 and 2020, 515 had a history of C-XRT. Upon propensity score matching in patients undergoing TAVR, Patients with a history of C-XRT showed significantly lower adjusted odds of in-hospital mortality (adjusted odd ratio [aOR] 0.04, 95 % CI [0.003-0.57], p = 0.017), lower mean LOS by 1.6 days (-1.88 to -1.26 days, p < 0.001) and reduced mean THC (-$74,720, [-$88,784 to -$60,655], p < 0.001). Additionally, patients with C-XRT had significantly lower adjusted odds of inpatient complications, mainly acute myocardial infarction, cerebrovascular events, acute respiratory failure, acute kidney injury, need for vasopressors and cardiopulmonary resuscitation, whereas similar odds of complications, including a requirement of intubation, mechanical ventilation, hemodialysis, and cardiogenic shock., Conclusion: Our analysis showed reduced adjusted odds of in-hospital mortality, length of stay, total hospital charges, and inpatient complications in patients undergoing TAVR with a history of C-XRT. TAVR appears to be a safe and viable alternative in this population subgroup., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Published by Elsevier Inc.)

Background: Transcatheter aortic valve replacement (TAVR) is a revolutionary procedure for severe aortic stenosis. The coexistence of chronic kidney disease (CKD) and TAVR introduces a challenge that significantly impacts patient outcomes., Aim: To define readmission rates, predictors, and causes after TAVR procedure in CKD stage 1-4 patients., Methods: We used the national readmission database 2018 and 2020 to look into readmission rates, causes and predictors after TAVR procedure in patients with CKD stage 1-4., Results: Out of 24758 who underwent TAVR and had CKD, 7892 (32.4%) patients were readmitted within 90 days, and had higher adjusted odds of being females (adjusted odds ratio: 1.17, 95%CI: 1.02-1.31, P = 0.02) with longer length of hospital stay > 6 days, and more comorbidities including but not limited to diabetes mellitus, anemia, and congestive heart failure (CHF)., Conclusion: Most common causes of readmission included CHF (18.0%), sepsis, and complete atrioventricular block. Controlling readmission predictors with very close follow-up is warranted to prevent such high rate of readmission., Competing Interests: Conflict-of-interest statement: We have no financial relationships to disclose., (©The Author(s) 2024.
