Background: Patients with end-stage renal disease on hemodialysis (ESRD-HD) and aortic stenosis have poor prognosis. The role of transcatheter aortic valve replacement (TAVR) in this high-risk population is debated. Methods: We compared the outcomes among ESRD-HD Medicare beneficiaries who were managed with TAVR, surgical AVR (SAVR), or conservative management for aortic stenosis between 2015 and 2017, using overlap propensity score weighting analysis to control for differences in treatment assignment. The primary outcome was all-cause mortality and was compared between treatment groups as well as to age-sex matched mortality for ESRD-HD in the US population. Secondary outcomes included trend of heart failure hospitalizations. Results: A total of 8107 ESRD-HD patients with aortic stenosis were included, 4130 (50%) underwent TAVR, 2565 (31.6%) underwent SAVR, and 1412 (17.4%) were managed conservatively. TAVR patients had more comorbidities and higher frailty compared with the other 2 groups. Thirty-day mortality was lower with TAVR compared with SAVR (4.6% versus 12.8%, P <0.01). After a median follow-up of 465 days (interquartile range, 261–759), on overlap propensity score weighting analysis, there was no difference in mortality between TAVR and SAVR (adjusted hazard ratio, 1.02 [95% CI, 0.91–1.15], P =0.7), and mortality was lower with TAVR compared with conservative management (adjusted hazard ratio, 0.53 [95% CI, 0.47–0.60], P <0.001). Standardized mortality ratios with TAVR, SAVR, and conservative management compared with age-sex matched ESRD-HD US population were 1.24, 1.27, and 1.83, respectively. The rate of heart failure admissions declined after TAVR (incidence rate ratio, 0.55 [95% CI, 0.48–0.62], P <0.001) and SAVR (incidence rate ratio, 0.76 [95% CI, 0.65–0.88], P <0.001). Conclusions: In ESRD-HD patients with aortic stenosis, mortality was lower in the short-term with TAVR compared with SAVR but comparable in the mid-term. AVR is associated with an improvement in survival and reduction in heart failure hospitalizations compared with conservative management.

A 54-year-old man with remote large cell non-Hodgkin’s lymphoma in remission following R-CHOP and severe atopic dermatitis was transferred from another hospital with a non-ST elevation myocardial infarction. Over the preceding year, the patient had suffered recurrent admissions for acutely decompensated heart failure with a newly depressed left ventricular ejection fraction (LVEF) of 20% by echocardiography and rapidly progressive end-stage renal disease of unclear etiology requiring the initiation of hemodialysis. Prior workup had demonstrated an infrarenal abdominal aortic aneurysm and bilateral common iliac artery aneurysms with subsequent computed tomography (CT) additionally demonstrating a superior mesenteric artery aneurysm. The patient was taken for immediate coronary arteriography, which demonstrated giant aneurysms in the left main and right coronary arteries, as well as multivessel severe stenoses. CT coronary angiogram demonstrated significant circumferential wall thickening throughout the coronary vasculature. Given concern for IgG4-related disease (IgG4-RD), a renal biopsy was pursued that confirmed the diagnosis. 18F-fluorodeoxyglucose positron emission tomography-CT identified only mild aortic inflammation. The patient was treated with high-dose steroids and rituximab. The serological inflammatory markers improved, and he underwent coronary artery bypass grafting. Pericardial, aortic adventitial, left internal mammary artery, and saphenous vein biopsies showed cardiovascular involvement of IgG4-RD. The patient has been maintained on rituximab with normalization of his LVEF and no recurrence of chest pain over the past eighteen months. IgG4-RD is a fibroinflammatory systemic disease newly described in 2003 and only recently found to involve the cardiovascular system with several reports of peripheral aneurysmal disease. To our knowledge, the current case represents the first report of a patient successfully treated for biopsy-proven IgG4-RD associated with coronary artery disease and left ventricular systolic dysfunction. IgG4-RD may represent a novel mechanism underlying some forms of peripheral and coronary arterial disease and may offer new insights into vascular biology.

Introduction: End-stage renal disease (ESRD) is associated with increased complications due to oral anticoagulation (OAC) use for stroke prevention in atrial fibrillation (AF). Left atrial appendage occlusion (LAAO) is indicated for patients who cannot tolerate or prefer not to use OAC but the outcomes of LAAO in ESRD has not been well studied. Methods: Using National Readmission Database January 2016-December 2017, we identified all adult AF patients who had LAAO performed in the months of January to November with no missing length of stay and/or mortality information. We excluded patients who had ablation, device implantation/revision, other form of LAAO and/or coronary artery bypass graft surgery performed during index hospitalization. 1:1 propensity score matching was performed for patients with and without ESRD based on variables shown in Table 1. The main outcome of interest was early mortality defined as mortality of index hospitalization or 30-day readmissions and index hospital complications. Results: A total of 13,790 procedures were included and of these 370 patients had history of ESRD. The baseline characteristics before and after matching are shown in table 1. After propensity score matching, ESRD group was associated with significantly higher early mortality, 30-day readmissions, systemic embolism and pericardial complications (Table 2). In the matched cohort, none of the patients had postprocedural cerebrovascular accident, transient ischemic attack, device thrombosis and device embolization. After propensity matching 2 (0.5%) developed acute kidney injury requiring hemodialysis. Conclusions: ESRD is associated with higher LOS, index hospital complications and early mortality from LAAO compared to patients without ESRD. Further studies comparing outcomes between OAC use and LAAO are warranted.
