Outcomes of concomitant percutaneous coronary interventions and transcatheter aortic valve replacement.

ABSTRACT:

Introduction

Coronary artery disease is a common diagnosis among patients undergoing transcatheter aortic valve replacement (TAVR). The treatment and timing of percutaneous coronary intervention (PCI) remain controversial. We sought to compare in-hospital periprocedural outcomes of combined TAVR and PCI during the same index hospitalization versus the isolated TAVR procedure.

Material and methods

The study population was extracted from the 2016 Nationwide Readmissions Data (NRD) using International Classification of Diseases, tenth edition, clinical modifications/procedure coding system codes for TAVR, coronary PCI, and post-procedural complications. Study endpoints included in-hospital all-cause mortality, length of index hospital stay, cardiogenic shock, need for mechanical circulatory support (MCS) devices, mechanical complications of prosthetic valve, paravalvular leak (PVL), acute kidney injury (AKI), bleeding and total hospital charges. Propensity matching was used to adjust for baseline characteristics.

Results

There were 23,604 TAVRs in the 2016 NRD, of which 852 were combined with PCI during the same index hospitalization. Mean age was 80.5 years and 45.9% were female. In comparison to isolated TAVR, TAVR-PCI was associated with higher in-hospital all-cause mortality (4.5% vs. 1.7%, p < 0.01), longer length of stay (10.5 vs. 5.4 days, p < 0.01), and higher incidence of cardiogenic shock (9.4% vs. 2.1%, p < 0.01), use of MCS devices (6.8% vs. 0.7%, p < 0.01), mechanical complications of prosthetic valve (6.8% vs. 0.7%, p < 0.01), PVL (0.9% vs. 0.4%, p = 0.01), AKI (25.5% vs. 11.5%, p < 0.01), bleeding (25.2% vs. 18.1%, p < 0.01), and total hospital charges ($354,725 vs. $220474, p < 0.01).

Conclusions

In comparison to isolated TAVR, combined TAVR-PCI was associated with a higher incidence of in-hospital morbidity and mortality. The association and mechanism of increased mortality warrant further study.

Project description:ObjectiveAlthough patients with significant coronary artery disease and aortic stenosis have traditionally undergone open valve replacement and bypass grafting, percutaneous coronary intervention (PCI) and transcatheter aortic valve replacement (TAVR) are increasingly considered. Because of the lack of data regarding timing of PCI/TAVR, in the present study we evaluated associations of staged and concomitant PCI/TAVR on outcomes in a nationally representative cohort.MethodsAdults who underwent TAVR and PCI were identified using the 2016 to 2018 Nationwide Readmissions Database. If PCI/TAVR occurred on the same day, patients were considered Concomitant and otherwise considered Staged. Staged were further classified as Early-Staged if both occurred in the same hospitalization or Late-Staged if TAVR ensued PCI in a subsequent hospitalization. Multivariable regression models were developed to evaluate the association of TAVR timing on outcomes. The primary end point was in-hospital mortality whereas perioperative complications including acute kidney injury and hospitalization costs were secondarily considered.ResultsOf an estimated 5843 patients, 843 (14.4%) were Concomitant and 745 (12.7%) and 4255 (72.8%) were Early-Staged and Late-Staged, respectively. Although age and TAVR access were similar, Concomitant had a lower proportion of chronic kidney disease and more commonly underwent single-vessel PCI. Staged showed similar risk-adjusted mortality but greater odds of acute kidney injury (Early-Staged adjusted odds ratio: 2.68; 95% CI, 1.57-4.55 and Late-Staged: 1.97; 95% CI, 1.29-2.99) compared with Concomitant. Although post-TAVR hospitalization duration was similar, total length of stay and costs were increased in Staged.ConclusionsConcomitant PCI/TAVR was associated with similar rates of in-hospital mortality but reduced rates of acute kidney injury and lower resource utilization. While evaluating patient-specific factors, concomitant PCI/TAVR might be reasonable in select individuals.

Project description:ImportanceThe US Centers for Medicare and Medicaid Services recently released an updated national coverage determination proposal for transcatheter aortic valve replacement (TAVR) that maintains a focus on hospital TAVR volume and percutaneous coronary intervention (PCI) volume, and the national coverage determination for transcatheter mitral valve repair (TMVr) also has PCI volume requirements. However, the associations between hospital PCI volume and TAVR and TMVr outcomes are unknown.ObjectiveTo investigate whether hospital inpatient PCI volume is associated with rates of risk-adjusted in-hospital mortality and 30-day hospital readmission after TAVR and TMVr.Design, setting, and participantsThis population-based cross-sectional study of the 2016 Nationwide Readmissions Database included procedures completed in hospitals with a minimum of 5 TAVR or 5 TMVr procedures between January 1, 2016, and November 30, 2016.ExposuresHospitals were divided into quartiles based on annual inpatient PCI volumes.Main outcomes and measuresPrimary outcomes were in-hospital mortality and 30-day readmission rates. The associations between hospital inpatient PCI quartile and outcomes were evaluated using Kruskal-Wallis tests. Risk adjustment for in-hospital mortality rates was done through inclusion of variables based on the Elixhauser comorbidity classification, and risk adjustment for 30-day readmission rates was done in accordance with the Hospital-Wide Readmission Measure methodology used by the Centers for Medicare and Medicaid Services for public reporting.ResultsThere were 283 hospitals that performed at least 5 TAVRs, with a median inpatient PCI volume of 386 (interquartile range, 299-571) procedures, and 125 hospitals that performed at least 5 TMVr procedures, with a median inpatient PCI volume of 451 (interquartile range, 326-651) procedures. There was no association between hospital inpatient PCI volume and median TAVR risk-standardized in-hospital mortality (median [IQR] rates: bottom quartile, 1.82% [1.77%-1.90%]; second quartile, 1.81% [1.76%-1.86%]; third quartile, 1.81% [1.75%-1.90%]; top quartile, 1.82% [1.76%-1.91%]; P = .75) or the 30-day readmission (median [IQR] rates: bottom quartile, 13.6% [13.2%-14.3%]; second quartile, 13.3% [12.7%-14.0%]; third quartile, 13.5% [12.7%-14.3%]; top quartile, 13.8% [12.8%-14.3%]; P = .10) rates. Similarly, there was no association between hospital inpatient PCI volume and median TMVr risk-standardized in-hospital mortality rates (median [IQR] rates: bottom quartile, 1.84% [1.47%-2.53%]; second quartile, 1.65% [1.21%-3.02%]; third quartile, 1.80% [1.52%-3.58%]; top quartile, 1.76% [1.33%-4.20%]; P = .71) or 30-day readmission rates (median [IQR] rates: bottom quartile, 13.4% [13.1%-13.6%]; second quartile, 13.1% [12.9%-13.5%]; third quartile, 13.1% [12.9%-13.5%]; top quartile, 13.3% [12.8%-13.6%]; P = .30).Conclusions and relevanceIn this study, there was no association between inpatient PCI volume and TAVR or TMVr outcomes. Further evidence is needed to support inclusion of PCI volume minimums in national coverage determination requirements for hospital TAVR and TMVr programs.

Project description:ObjectivesThis study sought to address a knowledge gap by examining the incidence, timing, and predictors of acute coronary syndrome (ACS) after transcatheter aortic valve replacement (TAVR) in Medicare beneficiaries.BackgroundEvidence about incidence and outcomes of ACS after TAVR is scarce.MethodsWe identified Medicare patients who underwent TAVR from 2012 to 2017 and were admitted with ACS during follow-up. We compared outcomes based on the type of ACS: ST-segment elevation myocardial infarction (STEMI), non-STEMI (NSTEMI), and unstable angina. In patients with non-ST-segment elevation ACS, we compared outcomes based on the treatment strategy (invasive vs. conservative) using inverse probability weighting analysis.ResultsOut of 142,845 patients with TAVR, 6,741 patients (4.7%) were admitted with ACS after a median time of 297 days (interquartile range: 85 to 662 days), with 48% of admissions occurring within 6 months. The most common presentation was NSTEMI. Predictors of ACS were history of coronary artery disease, prior revascularization, diabetes, valve-in-TAVR, and acute kidney injury. STEMI was associated with higher 30-day and 1-year mortality compared with NSTEMI (31.4% vs. 15.5% and 51.2% vs. 41.3%, respectively; p < 0.01). Overall, 30.3% of patients with non-ST-segment elevation ACS were treated with invasive approach. On inverse probability weighting analysis, invasive approach was associated with lower adjusted long-term mortality (adjusted hazard ratio: 0.69; 95% confidence interval: 0.66 to 0.73; p < 0.01) and higher risk of repeat revascularization (adjusted hazard ratio: 1.29; 95% confidence interval: 1.16 to 1.43; p < 0.001).ConclusionsAfter TAVR, ACS is infrequent (<5%), and the most common presentation is NSTEMI. Occurrence of STEMI after TAVR is associated with a high mortality with nearly one-third of patients dying within 30 days. Optimization of care is needed for post-TAVR ACS patients and if feasible, invasive approach should be considered in these high-risk patients.

Project description:ObjectiveTo identify outcomes of patients undergoing emergency transcatheter aortic valve replacement (TAVR) and determine predictors of in-hospital mortality.BackgroundEmergency TAVR has emerged as a viable treatment strategy for patients with decompensated severe aortic stenosis and/or regurgitation; however, data on patients undergoing emergency TAVR are limited.MethodsAll emergency TAVR procedures were identified from a single tertiary academic center between January 2015 and August 2018.Results31 patients underwent emergency TAVR due to cardiogenic shock (26 patients), electrical instability with incessant ventricular tachycardia (2 patients), severe refractory angina (2 patients), and decompensated heart failure with hypoxemic respiratory failure requiring mechanical ventilation (1 patient). Mechanical circulatory support (MCS) was used in 16 (51.6%). MCS initiation occurred immediately prior to TAVR in 10 patients and placed post-TAVR in 6 patients. 6 patients died before hospital discharge (in-hospital mortality 19.4%). 1-year and 2-year survival rates were 61.0% and 55.9%, respectively. Univariate predictors of in-hospital mortality were preprocedural pulmonary artery pulsatility index (PAPi) ≤1.8 (66.7% vs. 20.0%, p=0.01), intraprocedural cardiopulmonary resuscitation (CPR) (83.3% vs 4.0%, p ≤ 0.001), acute kidney injury post-TAVR (80.0% vs. 4.2%, p ≤ 0.001), initiation of dialysis post-TAVR (60.0% vs. 4.2%, p ≤ 0.001), and MCS initiation post-TAVR (50.0% vs. 12.0%, p=0.03). MCS initiation before TAVR was associated with improved survival compared with post-TAVR initiation.ConclusionEmergency TAVR in extreme risk patients with acute decompensated heart failure or cardiogenic shock secondary to severe aortic valve disease is associated with high in-hospital mortality rates. Careful patient selection taking into account right heart function, assessed by PAPi, and early utilization of MCS may improve survival following emergency TAVR.

Project description:ImportanceThe Centers for Medicare & Medicaid Services national coverage determination for transcatheter aortic valve replacement (TAVR) includes volume requirements for surgical aortic valve replacement (SAVR) for hospitals seeking to initiate or continue TAVR programs. Evidence regarding the association between SAVR volume and TAVR outcomes is limited.ObjectiveTo examine the association of hospital SAVR and combined SAVR and TAVR volumes with patient outcomes of TAVR procedures performed within 1 year, 2 years, and for the entire period after initiation of TAVR programs.Design, setting, and participantsThis observational cohort study included 60 538 TAVR procedures performed in 438 hospitals between October 1, 2011, and December 31, 2015, among Medicare beneficiaries.Main outcomes and measuresThe associations between SAVR volume, SAVR and TAVR volumes, and risks of death, death or stroke, and readmissions within 30 days were determined using a hierarchical logistic regression model adjusting for patient and hospital characteristics. The association between SAVR and SAVR and TAVR volumes and 1-year and 2-year mortality after TAVR procedures was determined using a multivariable proportional hazard model with a robust variance estimator. The associations for procedures performed within 1 year, 2 years, and for the entire period after initiation of TAVR programs were examined.ResultsAmong the 60 538 patients, 29 173 were women and 31 365 were men, with a mean (SD) age of 82.3 (8.0) years. Hospitals with high SAVR volume (mean annual volume, ≥97 per year) were more likely to adopt TAVR early and had a higher growth in TAVR volumes over time (median TAVR volume by hospitals with high SAVR volume and low SAVR volume: year 1, 32 vs 19; year 2, 48 vs 28; year 3, 82 vs 38; year 4, 118 vs 54; P < .001). In adjusted analysis, high hospital SAVR volume alone was not associated with better patient outcomes after TAVR. When hospital TAVR and SAVR volumes were jointly analyzed, patients treated in hospitals with high TAVR volume had lower 30-day mortality after TAVR (high TAVR and low SAVR vs low TAVR and low SAVR: odds ratio, 0.85; 95% CI, 0.72-0.99; high TAVR and high SAVR vs low TAVR and high SAVR: odds ratio, 0.81; 95% CI, 0.69-0.95), the effect of which was more pronounced when hospitals also had high SAVR volume. Patients treated in hospitals with high SAVR volume and high TAVR volume had the lowest 30-day mortality (vs hospitals with low SAVR volume and TAVR volume: odds ratio, 0.77; 95% CI, 0.66-0.89).Conclusions and relevanceHospitals with high SAVR volume are most likely to be fast adopters of TAVR. Hospital SAVR volume alone is not associated with better TAVR outcomes. Accumulating high volumes of TAVR is associated with lower mortality after TAVR, particularly when hospitals have high SAVR volumes. Hospitals with high caseloads of both SAVR and TAVR are likely to achieve the best outcomes.

Project description:BackgroundThe past decade has witnessed an ever-increasing momentum of transcatheter aortic valve replacement (TAVR) and a subsequent paradigm shift in the contemporary management of severe aortic stenosis (AS). We conducted a multi-centric TAVR registry based on Chinese patients (the China Aortic valve tRanscatheter Replacement registrY [CARRY]) to delineate the clinical characteristics and outcomes of Chinese patients who underwent TAVR and compare the results between different valve types in different Chinese regions.MethodsCARRY is an all-comer registry of aortic valve disease patients undergoing TAVR across China and was designed as an observational study that retrospectively included all TAVR patients at each participating site. Seven hospitals in China participated in the CARRY, and 1204 patients from April 2012 to November 2020 were included. Categorical variables were compared using the chi-squared test, and continuous variables were analyzed using a t test or analysis of variance (ANOVA) test. The Kaplan-Meier curve was used to estimate the risk of adverse events during follow-up.ResultsThe mean age of the patients was 73.8 ± 6.5 years and 57.2% were male. The median Society of Thoracic Surgeon-Predicted Risk of Mortality score was 6.0 (3.7-8.9). Regarding the aortic valve, the proportion of bicuspid aortic valve (BAV) was 48.5%. During the hospital stay, the stroke rate was 0.7%, and the incidence of high-degree atrioventricular block indicating permanent pacemaker implantation was 11.0%. The in-hospital all-cause mortality rate was 2.2%. After 1 year, the overall mortality rate was 4.5%. Compared to patients with tricuspid aortic valve (TAV), those with BAV had similar in-hospital complication rates, but a lower incidence of in-hospital mortality (1.4% vs. 3.3%) and 1 year mortality (2.3% vs. 5.8%).ConclusionsTAVR candidates in China were younger, higher proportion of BAV, and had lower rates of post-procedural complications and mortality than other international all-comer registries. Given the use of early generation valves in the majority of the population, patients with BAV had similar rates of complications, but lower mortality than those with TAV. These findings further propel the extension of TAVR in low-risk patients.Trial registrationhttps://www.chictr.org.cn/ (No. ChiCTR2000038526).
