Background Patients undergoing transcatheter aortic valve replacement (TAVR) are likely to be discharged to a location other than home. We aimed to assess the association between discharge disposition after TAVR and patient survival at 1 year. Methods Patients admitted from home and survived till discharge after TAVR were divided into two groups based on discharge disposition (home discharge vs. non-home discharge). Pre-operative factors predicting the odds of not being discharged home were identified by using multivariable logistic regression analysis. Study patients were matched one-to-one via a propensity scoring method. Differences in procedural outcomes were compared. Survival of both unmatched and matched pairs was evaluated by using the Kaplan-Meier method with the Kleine-Moesch-Berger stratified log-rank test. Results Out of 1,160 TAVR patients, 851 were admitted from home and survived till discharge. The incidence non-home discharge was 19% (n = 159). Factors that were significantly associated with non-home discharge were older age, non-transfemoral approach, female sex, frailty status, history of chronic lung disease, pacemaker placement and insulin-dependent diabetes mellitus. One-to-one propensity score matching resulted in 141 patient pairs with similar age, operative risk, frailty and functional status. At 1-year follow-up, all-cause mortality rates were significantly higher in the non-home group than their home counterparts (18% vs. 3%, P = 0.006; stratified log rank test: P = 0.006). Conclusions A considerable number of TAVR patients are discharged to a location other than home after the procedure. Not being discharged home after TAVR is associated with a high mortality risk at 1 year.

Background The impact of frailty status on TAVR outcomes in nonagenarians is unknown. The present study aims to investigate the impact of frailty status on procedural outcomes and overall survival in nonagenarians after TAVR. Methods A frailty score (FS) was derived by using preoperative grip strength, gait speed, serum albumin, and daily activities. Patients were divided into two groups: Frail (FS ≥ 3/4) and Non-Frail (FS 90 years underwent full assessment for frailty status. There was a significant improvement in overall health status of non-frail patients (mean difference: 11.03, P = 0.032). Unadjusted 30-day and 2-year mortality rates were higher in the frail group than the non-frail group. (14% vs. 2% P = 0.059; 31% vs. 9% P = 0.018). Kaplan-Meier estimated all-cause mortality to be significantly higher in the frail group (log-rank test; P = 0.042). Frailty status was independently associated with increased mortality (hazard ratio: 1.84, 95% C.I: 1.06–3.17; P = 0.028) after TAVR. Conclusion Among nonagenarians selected to undergo TAVR for severe aortic stenosis, a considerable number are frail. Nonfrail patients report a significant improvement in overall health status in the short term. Worse frailty is strongly associated with diminished long-term survival. © 2017 Wiley Periodicals, Inc.

Mechanical rotational atherectomy with the Rotablator is widely used for percutaneous coronary revascularization, but the ideal debulking strategy remains unknown. The purpose of this study was to compare the immediate and late results after Rotablator using two treatment strategies: Large burrs (burr/artery ratio of0.7) to achieve maximal debulking (lesion debulking strategy) or small burrs (burr/artery ratioor = 0.7) to modify lesion compliance (lesion modification strategy). Two hundred twenty-two patients at six centers were prospectively enrolled in this study and randomly assigned to large (n = 104 patients with 118 lesions) or small (n = 118 patients with 136 lesions) burrs. The primary endpoint was final diameter stenosis at the end of the procedure, and secondary endpoints included inhospital angiographic and clinical complications, and target lesion revascularization at 6 months. Baseline demographic and angiographic characteristics were similar. There were no differences in procedural success, the extent of immediate lumen enlargement, inhospital ischemic complications, or late target vessel revascularization. However, compared with small burrs, patients randomized to large burrs were more likely to experience serious angiographic complications (5.1% vs. 12.7%, P0.05) immediately after atherectomy. This study suggests that a routine lesion modification strategy employing small burrs (burr/artery ratioor = 0.7) achieves similar immediate lumen enlargement and late target vessel revascularization compared with a more aggressive debulking strategy (burr/artery ratio0.7), but with fewer angiographic complications.
