Vascular Teams in Peripheral Vascular Disease

Peripheral vascular disease affects millions of individuals worldwide, and results in significant morbidity and mortality. The complex nature of the disease, the presence of multiple comorbidities, and the existence of a wide variety of therapeutic options suggests that a multidisciplinary approach to treatment has the potential to improve care of these patients. The success of the heart team for complex coronary artery and structural heart disease could serve as a model for the efficient and effective management of patients with peripheral vascular disease. In this paper, the authors propose a multidisciplinary vascular team approach for the treatment of critical limb ischemia, pulmonary embolism, acute ischemic stroke, and acute aortic syndromes. The successful implementation of such vascular teams has the potential to significantly enhance quality of care, improve clinical outcomes, and reduce costs. Prospective evaluation is warranted to determine how to best integrate this approach into routine clinical care.

Patterns of In-Hospital Mortality and Bleeding Complications Following PCI for Very Elderly Patients: Insights from the Dartmouth Dynamic Registry

Background Very elderly patients (age ≥ 85 years) are a rapidly increasing segment of the population. As a group, they experience high rates of in-hospital mortality and bleeding complications following percutaneous coronary intervention (PCI). However, the relationship between bleeding and mortality in the very elderly is unknown. Methods Retrospective review was performed on 17,378 consecutive PCI procedures from 2000 to 2015 at Dartmouth-Hitchcock Medical Center. Incidence of bleeding during the index PCI admission (bleeding requiring transfusion, access site hematoma > 5 cm, pseudoaneurysm, and retroperitoneal bleed) and in-hospital mortality were reported for four age groups (< 65 years, 65–74 years, 75–84 years, and ≥ 85 years). The mortality of patients who suffered bleeding complications and those who did not was calculated and multivariate analysis was performed for in-hospital mortality. Lastly, known predictors of bleeding were compared between patients age < 85 years and age ≥ 85 years. Results Of 17,378 patients studied, 1019 (5.9%) experienced bleeding and 369 (2.1%) died in-hospital following PCI. Incidence of bleeding and in-hospital mortality increased monotonically with increasing age (mortality: 0.94%, 2.27%, 4.24% and 4.58%; bleeding: 3.96%, 6.62%, 10.68% and 13.99% for ages < 65, 65–74, 75–84 and ≥ 85 years, respectively). On multivariate analysis, bleeding was associated with increased mortality for all age groups except patients age ≥ 85 years [odds ratio (95% CI): age < 65 years, 3.65 (1.99–6.74); age 65–74 years, 2.83 (1.62–4.94); age 75–84 years, 3.86 (2.56–5.82), age ≥ 85 years: 1.39 (0.49–3.95)]. Conclusions Bleeding and mortality following PCI increase with increasing age. For the very elderly, despite high rates of bleeding, bleeding is no longer predictive of in-hospital mortality following PCI.

Transfemoral TAVR in Nonagenarians: From the CENTER Collaboration

ObjectivesThis study aimed to compare differences in patient characteristics and clinical outcomes of nonagenarians undergoing transcatheter aortic valve replacement (TAVR) versus patients younger than 90 years of age and to test the predictive accuracy of the logistic EuroSCORE (European System for Cardiac Operative Risk Evaluation), the EuroSCORE II, and the STS-PROM (Society of Thoracic Surgeons Predicted Risk of Mortality) for mortality after TAVR in nonagenarians.BackgroundThe prevalence of severe aortic valve stenosis is increasing due to the rising life expectancy. However, there are limited data evaluating outcomes in patients older than 90 years of age. Moreover, the predictive accuracy of risk scores for mortality has not been evaluated in nonagenarian patients undergoing transfemoral TAVR.MethodsThe CENTER (Cerebrovascular EveNts in Patients Undergoing TranscathetER Aortic Valve Implantation) collaboration (N = 12,381) is an international collaboration consisting of 3 national registries, 6 local or multicenter registries, and 1 prospective clinical study, selected through a systematic online search. The primary endpoint of this study was the difference in 30-day all-cause mortality and stroke after TAVR in nonagenarians versus patients younger than 90 years of age. Secondary endpoints included differences in baseline characteristics, in-hospital outcomes, and the differences in predictive accuracy of the logistic EuroSCORE, the EuroSCORE II, and STS-PROM.ResultsA total of 882 nonagenarians and 11,499 patients younger than 90 years of age undergoing transfemoral TAVR between 2007 and 2018 were included. Nonagenarians had considerably fewer comorbidities than their counterparts. Nevertheless, rates of 30-day mortality (9.9% vs. 5.4%; relative risk [RR]: 1.8; 95% confidence interval [CI]: 1.4 to 2.3; p = 0.001), in-hospital stroke (3.0% vs. 1.9%; RR: 1.5; 95% CI: 1.0 to 2.3; p = 0.04), major or life-threatening bleeding (8.1% vs. 5.5%; RR: 1.6; 95% CI: 1.1 to 2.2; p = 0.004), and new-onset atrial fibrillation (7.9% vs. 5.2%; RR: 1.6; 95% CI: 1.1 to 2.2; p = 0.01) were higher in nonagenarians. The STS-PROM adequately estimated mortality in nonagenarians, with an observed-expected mortality ratio of 1.0.ConclusionsIn this large, global, patient-level analysis, mortality after transfemoral TAVR was 2-fold higher in nonagenarians compared with patients younger than 90 years of age, despite the lower prevalence of baseline comorbidities. Moreover, nonagenarians had a higher risk of in-hospital stroke, major or life-threatening bleeding, and new-onset atrial fibrillation. The STS-PROM was the only surgical risk score that accurately predicted the risk of mortality in nonagenarians.

Association Between β-Blockers and Outcomes in Heart Failure With Preserved Ejection Fraction: Current Insights From the SwedeHF Registry

Backgroundβ-Blockers have an uncertain effect in heart failure with a preserved ejection fraction of 50% or higher (heart failure with preserved ejection fraction [HFpEF]).Methods and ResultsWe included patients with HFpEF from the Swedish Heart Failure Registry (SwedeHF) enrolled from 2011 through 2018. In a 2:1 propensity-score matched analysis (β-blocker use vs nonuse), we assessed the primary outcome first HF hospitalization, the coprimary outcome cardiovascular (CV) death, and the secondary outcomes of all-cause hospitalization and all-cause death. We performed intention-to-treat and a per-protocol consistency analyses. There were a total of 14,434 patients (median age 79 years, IQR 71–85 years, 51% women); 80% were treated with a β-blocker at baseline. Treated patients were younger and had higher rates of atrial fibrillation and coronary artery disease, and higher N-terminal pro-B-type natriuretic peptide levels. In the 4412:2206 patient matched cohort, at 5 years, 42% (95% CI 40%–44%) vs 44% (95% CI 41%–47%) had a HF admission and 38% (IQR 36%–40%) vs 40% (IQR 36%–42%) died from CV causes. In the intention-to-treat analysis, β-blocker use was not associated with HF admissions (hazard ratio 0.95 [95% CI 0.87–1.05, P = .31]) or CV death (hazard ratio 0.94 [95% CI 0.85–1.03, P = .19]). In the subgroup analyses, men seemed to have a more favorable association between β-blockers and outcomes than did women. There were no associations between β-blocker use and secondary outcomes.ConclusionsIn patients with HFpEF, β-blocker use is common but not associated with changes in HF hospitalization or cardiovascular mortality. In the absence of a strong rational and randomized control trials the case for β-blockers in HFpEF remains inconclusive.Bullet points● The effect of β-blockers with heart failure with preserved ejection fraction of 50% or greater is uncertain.● In a propensity score–matched heart failure with preserved ejection fraction analysis in the SwedeHF registry, β-blockers were not associated with a change in risk for heart failure admissions or cardiovascular deaths.Lay summaryThe optimal treatment for heart failure with a preserved pump function remains unknown. Despite the lack of scientific studies, β-blockers are very commonly used. When matching patients with a similar risk profile in a large heart failure registry, the use of β-blockers for the treatment of heart failure with a preserved pump function was not associated with any changes in heart failure hospital admissions or cardiovascular death.     

State of the Art: Which Stent for Which Lesion in Peripheral Interventions?

Applications of endovascular procedures have been expanded dramatically throughout the human body for both occlusive and aneurysmal disease; arteries at the aortoiliac and femoropopliteal levels are no exception. Currently, interventional procedures are the 1st treatment option for most patients who have peripheral artery disease. Although balloon angioplasty alone offers good immediate and long-term results, the addition of stents has been proposed to improve the procedural success of angioplasty and extend its application to more patients with vascular disease. Stenting, however, is controversial. Its use is considered acceptable in the aortoiliac vessels but is more in dispute for the femoropopliteal vessels. Moreover, the rapid development of endovascular stents for peripheral applications has made stent selection a complicated task for clinical practitioners. Many factors influence the type of stent selected; therefore, knowledge of the stents available--including various designs and individual properties--is mandatory. Appropriate selection depends on adequate preprocedural evaluation of the lesion; the choice of approach; the choice of primary versus selective stent placement; the location and characteristics of the lesion; the availability of stents in the intervention suite; and the experience of the operator Several stents are now available, but they are not equivalent; it is important to select the stent that is best suited to the lesion. On the basis of our experience using different types of stents, as well as our review of the world medical literature, we summarize the properties of various stents and specific indications for their application. This report is intended for use as a practical guide to stent selection.
