Transcatheter aortic valve replacement versus surgical aortic valve replacement in patients with cirrhosis

To compare the in‐hospital outcomes in cirrhosis patients undergoing transcatheter aortic valve replacement (TAVR) versus those undergoing surgical aortic valve replacement (SAVR).

In-Hospital Outcomes of Atherectomy During Endovascular Lower Extremity Revascularization

Contemporary data on clinical outcomes after utilization of atherectomy in lower extremity endovascular revascularization are sparse. The study cohort was derived from Healthcare Cost and Utilization Project nationwide inpatient sample database from the year 2012. Peripheral endovascular interventions including atherectomy were identified using appropriate International Classification of Diseases, Ninth Revision, Clinical Modification diagnostic and procedural codes. The subjects were divided and compared in 2 groups: atherectomy versus no atherectomy. Two-level hierarchical multivariate mixed models were created. The coprimary outcomes were in-hospital mortality and amputation; secondary outcome was a composite of in-hospital mortality and periprocedural complications. Hospitalization costs were also assessed. Atherectomy utilization (odds ratio, 95% CI, p value) was independently predictive of lower in-hospital mortality (0.46, 0.28 to 0.75, 0.002) and lower amputation rates (0.83, 0.71 to 0.97, 0.020). Atherectomy use was also predictive of significantly lower secondary composite outcome of in-hospital mortality and complications (0.79, 0.69 to 0.90, 0.001). In the propensity-matched cohort, atherectomy utilization was again associated with a lower rate of amputation (11.18% vs 12.92%, p = 0.029), in-hospital mortality (0.71% vs 1.53%, p 0.001), and any complication (13.24% vs 16.09%, p 0.001). However, atherectomy use was also associated with higher costs (

Multivessel Percutaneous Coronary Interventions in the United States: Insights From the Nationwide Inpatient Sample.

Contemporary real-world data on clinical outcomes after utilization of coronary atherectomy are sparse. The study cohort was derived from Healthcare Cost and Utilization Project Nationwide Inpatient Sample database from year 2012. Percutaneous coronary interventions including atherectomy were identified using appropriate International Classification of Diseases, 9th Revision diagnostic and procedural codes. Two-level hierarchical multivariate mixed models were created. The primary outcome was a composite of in-hospital mortality and periprocedural complications; the secondary outcome was in-hospital mortality. Hospitalization costs were also assessed. A total of 107,131 procedures were identified in 2012. Multivariate analysis revealed that atherectomy utilization was independently predictive of greater primary composite outcome of in-hospital mortality and complications (odds ratio 1.34, 95% confidence interval 1.22 to 1.47, p <0.001) but was not associated with any significant difference in terms of in-hospital mortality alone (odds ratio 1.22, 95% confidence interval 0.99 to 1.52, p 0.063). In the propensity-matched cohort, atherectomy utilization was again associated with a higher rate of complications (12.88% vs 10.99%, p = 0.001), in-hospital mortality +a ny complication (13.69% vs 11.91%, p = 0.003) with a nonsignificant difference in terms of in-hospital mortality alone (3.45% vs 2.88%, p = 0.063) and higher hospitalization costs (

Influence of same-day admission on outcomes following transcatheter aortic valve replacement.

Use of transcatheter endovascular stenting has been increasing in the treatment of coarctation of aorta (CoA). The present study was undertaken on adults with CoA who underwent stent placement from 2000 to 2011 to analyze the relation of hospital volumes to the outcomes of stenting in adults with CoA. It was a retrospective study based on Healthcare Cost and Utilization Projects Nationwide Inpatient Sample (NIS) database from 2000 to 2011 and identified subjects using the International Classification of Diseases, Ninth Revision, Clinical Modification procedure code of 747.10 (CoA). Annual hospital volume was calculated using unique hospital identifiers. Weights provided by the Nationwide Inpatient Sample were used to generate national estimates. A total of 105 (weighted 521) subjects were identified with International Classification of Diseases, Ninth Revision, code of 39.90 (Endovascular stent). Hospital volumes were divided into tertiles. We compared the highest tertile (≥3 procedures annually) with other tertiles (<3 procedure annually). The composite outcomes of the analysis were procedure-related complications, length of stay (LOS), and cost in relation to the hospital volume. No inhospital death was reported in either group. Hospitals with ≥3 procedures annually had significantly lower incidence of complications (9.5% vs 23.0%) compared to the hospitals with <3 procedures annually (p-value 0.002). Similar results were obtained after multivariate regression analysis in relation to hospital volume. Shorter LOS and lower cost were observed with annual hospital volume of ≥3 procedures. In conclusion, stenting adults for CoA is remarkably safe, and the outcomes of the procedure have improved in centers with annual hospital volume of ≥3 procedures. There is also decreasing trend of procedure-related complications, shorter LOS, and lower costs compared to centers with annual volume <3 procedures.

Impact of glycoprotein IIb/IIIa inhibitors use on outcomes after lower extremity endovascular interventions from nationwide inpatient sample (2006–2011)

Background: Multivessel coronary artery disease carries significant mortality risk. Comprehensive data on inhospital outcomes following multivessel percutaneous coronary intervention (MVPCI) are sparse. Methods: We queried the Healthcare Cost and Utilization Project’s nationwide inpatient sample (NIS) between 2006 and 2011 using different International Classification of Diseases, 9th Revision, Clinical Modification procedure codes. The primary outcome was inhospital all-cause mortality, and the secondary outcome was a composite of inhospital mortality and periprocedural complications. Results: The overall mortality was low at 0.73% following MVPCI. Multivariate analysis revealed that (odds ratio, 95% confidence interval, P value) age (1.63, 1.48-1.79; <.001), female sex (1.19, 1.00-1.42; P = .05), acute myocardial infarction (AMI; 2.97, 2.35-3.74; <.001), shock (17.24, 13.61-21.85; <.001), a higher burden of comorbidities (2.09, 1.32-3.29; .002), and emergent/urgent procedure status (1.67, 1.30-2.16; <.001) are important predictors of primary and secondary outcomes. MVPCI was associated with higher mortality, length of stay (LOS), and cost of care as compared to single vessel single stent PCI. Conclusion: MVPCI is associated with higher inhospital mortality, LOS, and hospitalization costs compared to single vessel, single stent PCI. Higher volume hospitals had lower overall postprocedural mortality rate along with shorter LOS and lower hospitalization costs following MVPCI.

Transcatheter pulmonary valve implantation: A cross-sectional US experience

ABSTRACT Introduction: Patients with bicuspid aortic valve (BAV) have traditionally been excluded from large randomized clinical trials involving transcatheter aortic valve replacements (TAVR). Technical enhancements, availability of new generation devices and improved outcomes have led to a marked increase in TAVR volume across the world including off label use in patients with BAV stenosis. Areas covered: In this manuscript, we have reviewed the currently available data regarding safety, efficacy, and outcomes of TAVR in patients with BAV stenosis. 11 large observational studies with near 1300 patients with BAV stenosis were included to summarizes outcomes of TAVR. Expert Commentary: The present review suggested that TAVR may be a safe and feasible treatment modality in BAV stenosis patients. New generation devices were associated with high device success rate whereas higher adverse procedural events were observed in early generation devices. There are no differences in post procedural outcomes with new generation TAVR devices for BAV when compared to tricuspid aortic anatomy. Larger studies are needed to evaluate the long-term outcome and durability of TAVR in patients with BAV.
