RESUMEN
Background It is unclear how to geographically distribute percutaneous coronary intervention (PCI) programs to optimize patient outcomes. The Washington State Certificate of Need program seeks to balance hospital volume and patient access through regulation of elective PCI. Methods and Results We performed a retrospective cohort study of all non-Veterans Affairs hospitals with PCI programs in Washington State from 2009 to 2018. Hospitals were classified as having (1) full PCI services and surgical backup (legacy hospitals, n=17); (2) full services without surgical backup (new certificate of need [CON] hospitals, n=9); or (3) only nonelective PCI without surgical backup (myocardial infarction [MI] access hospitals, n=9). Annual median hospital-level volumes were highest at legacy hospitals (605, interquartile range, 466-780), followed by new CON, (243, interquartile range, 146-287) and MI access, (61, interquartile range, 23-145). Compared with MI access hospitals, risk-adjusted mortality for nonelective patients was lower for legacy (odds ratio [OR], 0.59 [95% CI, 0.48-0.72]) and new-CON hospitals (OR, 0.55 [95% CI, 0.45-0.65]). Legacy hospitals provided access within 60 minutes for 90% of the population; addition of new CON and MI access hospitals resulted in only an additional 1.5% of the population having access within 60 minutes. Conclusions Many PCI programs in Washington State do not meet minimum volume standards despite regulation designed to consolidate elective PCI procedures. This CON strategy has resulted in a tiered system that includes low-volume centers treating high-risk patients with poor outcomes, without significant increase in geographic access. CON policies should re-evaluate the number and distribution of PCI programs.

Objectives: This study was conducted to determine why heart teams recommended transcatheter aortic valve replacement (TAVR) versus surgical AVR (SAVR) for patients at low predicted risk of mortality (PROM) and describe outcomes of these cases. Background: Historically, referral to TAVR was based predominately on the Society of Thoracic Surgeons (STS) risk model's PROM >3%. In selected cases, heart teams had latitude to overrule these scores. The clinical reasons and outcomes for these cases are unclear. Methods: Retrospective data were gathered for all TAVR and SAVR cases conducted by 9 hospitals between 2013 and 2017. Results: Cases included TAVR patients with STS PROM >3% (n = 2,711) and ≤3% (n = 415) and SAVR with STS PROM ≤3% (n = 1,438). Leading reasons for recommending TAVR in the PROM ≤3% group were frailty (57%), hostile chest (22%), severe lung disease (16%), and morbid obesity (13%), and 44% of cases had multiple reasons. Most postoperative and 30-day outcomes were similar between TAVR groups, but the STS PROM ≤3% group had a one-day shorter length of stay (2.5 ± 3.4 vs. 3.5 ± 4.7 days; p ≤ 0.001) and higher one-year survival (91.6% vs. 86.0%, p=0.002). In patients with STS PROM ≤3%, 30-day mortality was higher for TAVR versus SAVR (2.0% vs. 0.6%; p < 0.001). Conclusions: Heart teams recommended TAVR in patients with STS PROM ≤3% primarily due to frailty, hostile chest, severe lung disease, and/or morbid obesity. Similar postoperative outcomes between these patients and those with STS PROM >3% suggest that decisions to overrule STS PROM ≤3% were merited and may have reduced SAVR 30-day mortality rate.

BACKGROUND: Patients with small aortic annuli (SAA) are prone to higher post-transcatheter aortic valve replacement (TAVR) transvalvular gradients and development of prosthesis-patient mismatch (PPM). In many patients with SAA, the choice of TAVR valve commonly involves choosing between the 26-mm Medtronic Evolut 2 (ME26) or the 23-mm Edwards Sapien 3 valve (ES23). We compared echocardiographic and clinical outcomes in patients with SAA undergoing TAVR with either valve. METHODS: We queried the Providence St. Joseph Health Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry database for patients undergoing TAVR with either the ES23 or ME26 between July 2015 and December 2018 at 11 hospitals. Post-TAVR echocardiographic and clinical results in-hospital, at 1 month, and at 1 year were examined. High gradient (HG) was defined as mean gradient (MG) ≥20 mm Hg. RESULTS: We identified 1162 patients with SAA undergoing TAVR with either the ME26 (n = 233) or ES23 valve (n = 929). Baseline characteristics between groups were similar. At 1 month, the ME26 was associated with a lower MG than the ES23 (7.7 ± 4.7 mm Hg vs 13.1 ± 4.9 mm Hg; P<.001) and moderate or severe PPM (11% and 3% vs 27% and 13%; P<.001). Occurrence of HG at 1 year was lower with the ME26 valve vs the ES23 valve (0% vs 15%; P<.001). In-hospital and follow-up clinical outcomes to 1 year were similar for both groups. CONCLUSION: TAVR in SAA with the ME26 is associated with lower incidence of HG or PPM compared with the ES23. While clinical outcomes at 1 year were similar, the long-term implications of these findings remain unknown.

Background Patient selection and outcomes for percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) have changed over the past decade. However, there is limited information on outcomes for both revascularization strategies in the same population. The study evaluated temporal changes in risk profile, procedural characteristics, and clinical outcomes for PCI- and CABG-treated patients. Methods and Results We analyzed all PCI and isolated CABG between 2005 and 2017 in nonfederal hospitals in Washington State. Descriptive analysis was performed to evaluate temporal changes in risk profile and, risk-adjusted in-hospital mortality. Over the study period, 178 474 PCI and 36 592 CABG procedures were performed. PCI and CABG volume decreased by 2.9% and 22.6%, respectively. Compared with 2005-2009, patients receiving either form of revascularization between 2014 and 2017 had a higher prevalence of comorbidities including diabetes mellitus and hypertension and dialysis. Presentation with ST-segment-elevation myocardial infarction (17% versus 20%) and cardiogenic shock (2.4% versus 3.4%) increased for patients with PCI compared with CABG. Conversely, clinical acuity decreased for patients receiving CABG over the study period. From 2005 to 2017, mean National Cardiovascular Data Registry CathPCI mortality score increased for patients treated with PCI (20.1 versus 22.4, P<0.0001) and decreased for patients treated with CABG (18.8 versus 17.8, P<0.0001). Adjusted observed/expected in-hospital mortality ratio increased for PCI (0.98 versus 1.19, P<0.0001) but decreased for CABG (1.21 versus 0.74, P<0.0001) over the study period. Conclusions Clinical acuity increased for patients treated with PCI rather than CABG. This resulted in an increase in adjusted observed/expected mortality ratio for patients undergoing PCI and a decrease for CABG. These shifts may reflect an increased use of PCI instead of CABG for patients considered to be at high surgical risk.

BACKGROUND: Intrathoracic complications (ITC) requiring emergency surgical intervention occur during transcatheter aortic valve replacement (TAVR). OBJECTIVES: Characterize the incidence, outcomes and predictors of ITC in a large cohort of transfemoral (TF) TAVR cases over a 5 year period. METHODS: Retrospective registry and chart review of all nonclinical trial TF-TAVR patients from seven centers within one hospital system from 2012-2016. ITC were defined as cardiac perforation, new or worsening pericardial effusion/tamponade, annular rupture, thoracic aortic injury, aortic valve dislodgement, and coronary artery occlusion. Procedural and 30-day outcomes and 1-year mortality were compared between ITC and no ITC patients. Multivariable logistic regression was used to identify predictors of ITC. RESULTS: Over the study period, 1,581 patients had TF-TAVR and 68 ITC occurred in 46 patients (2.9%). The most common ITCs were pericardial effusion/tamponade (59%), cardiac perforation (33%), and valve dislodgement (33%). ITC rate did not decline over time (rate (95% confidence interval) for 2012 = 0% (0-8.8%), 2013 = 1.3% (0-7.2%), 2014 = 4.4% (2.2-8.0%), 2015 = 3.5% (2.0-5.6%), and 2016 = 2.4% (1.5-3.8%)). ITC patients had worse 1-year survival (ITC: 60.7% (45.1-73.1%), no ITC: 88.7% (87.0-90.3%); p < .001). The majority of ITC patient deaths occurred within the first 30 days. Multivariable models to predict ITC were not successful. CONCLUSIONS: ITC did not decline over time in our cohort. Predictors of ITC could not be identified. While these events are rare, they are associated with worse procedural outcomes and mortality. Heart teams should continue to be prepared for emergency intervention.

Public reporting of health care data continues to proliferate as consumers and other stakeholders seek information on the quality and outcomes of care. Medicare's Hospital Compare website, the U.S. News & World Report hospital rankings, and several state-level programs are well known. Many rely heavily on administrative data as a surrogate to reflect clinical reality. Clinical data are traditionally more difficult and costly to collect, but more accurately reflect patients' clinical status, thus enhancing the validity of quality metrics. We describe the public reporting effort being launched by the American College of Cardiology and partnering professional organizations using clinical data from the National Cardiovascular Data Registry (NCDR) programs. This hospital-level voluntary effort will initially report process of care measures from the percutaneous coronary intervention (CathPCI) and implantable cardioverter-defibrillator (ICD) registries of the NCDR. Over time, additional process, outcomes, and composite performance metrics will be reported.

OBJECTIVES: This paper reviews the published data and reports 3 cases of thrombosis involving CoreValve (Medtronic, Minneapolis, Minnesota) and 1 involving Edward Sapien (Edwards Lifesciences, Irvine, California) devices. Three of these cases had pathological findings at autopsy. BACKGROUND: Only a limited number of cases of valve dysfunction with rapid increase of transvalvular aortic gradients or aortic insufficiency post-transcatheter aortic valve replacement (TAVR) have been described. This nonstructural valvular dysfunction has been presumed to be because of early pannus formation or thrombosis. METHODS: Through reviews of the published reports and 4 clinical cases, pathological and clinical findings of early valve thrombosis are examined to elucidate methods for recognition and identifying potential causes and treatments. RESULTS: This paper presents 4 cases, 2 of which had increasing gradients post-TAVR. All 3 pathology cases showed presence of a valve thrombosis in at least 2 TAV leaflets on autopsy, but were not visualized by transthoracic echocardiogram or transesophageal echocardiogram. One case was medically treated with oral anti coagulation with normalization of gradients. The consequence of valve thrombosis in all 3 pathology patients either directly or indirectly played a role in their early demise. At least 18 case reports of early valve thrombosis have been published. In 12 of these cases, the early treatment with anticoagulation therapy resolved the thrombus formation and normalized aortic pressures gradients successfully. CONCLUSIONS: These 4 cases elucidate the occurrence of valve thrombosis post-TAVR. Consideration should be given to treatment with dual antiplatelet therapy and oral anticoagulation in patients post-TAVR with increasing mean pressure gradients and maximum aortic valve velocity. Further research should be conducted to create guidelines for antithrombotic therapy following TAVR procedure.

AIMS: We sought to determine the degree of anticoagulation reversal required to mitigate bleeding, and assess the feasibility of using pegnivacogin to prevent ischaemic events in acute coronary syndrome (ACS) patients managed with an early invasive approach. REG1 consists of pegnivacogin, an RNA aptamer selective factor IXa inhibitor, and its complementary controlling agent, anivamersen. REG1 has not been studied in invasively managed patients with ACS nor has an optimal level of reversal allowing safe sheath removal been defined. METHODS AND RESULTS: Non-ST-elevation ACS patients (n = 640) with planned early cardiac catheterization via femoral access were randomized 2:1:1:2:2 to pegnivacogin with 25, 50, 75, or 100% anivamersen reversal or heparin. The primary endpoint was total ACUITY bleeding through 30 days. Secondary endpoints included major bleeding and the composite of death, myocardial infarction, urgent target vessel revascularization, or recurrent ischaemia. Enrolment in the 25% reversal arm was suspended after 41 patients. Enrolment was stopped after three patients experienced allergic-like reactions. Bleeding occurred in 65, 34, 35, 30, and 31% of REG1 patients with 25, 50, 75, and 100% reversal and heparin. Major bleeding occurred in 20, 11, 8, 7, and 10% of patients. Ischaemic events occurred in 3.0 and 5.7% of REG1 and heparin patients, respectively. CONCLUSION: At least 50% reversal is required to allow safe sheath removal after cardiac catheterization. REG1 appears a safe strategy to anticoagulate ACS patients managed invasively and warrants further investigation in adequately powered clinical trials of patients who require short-term high-intensity anticoagulation.

BACKGROUND AND OBJECTIVES: Rates of hospitalization are known to be high in patients with kidney disease. However, ongoing risks of subsequent hospitalization and mortality are uncertain. The primary objective was to evaluate patients with kidney disease for long-term risks of subsequent hospitalization, including admissions resulting in death. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Patients hospitalized in Washington State between April of 2006 and December of 2008 who survived to discharge (n=676,343) were classified by International Classification of Disease codes into CKD (n=27,870), dialysis (n=6131), kidney transplant (n=1100), and reference (n=641,242) cohorts. Cox proportional hazard models controlling for age, sex, payer, comorbidity, previous hospitalization, primary diagnosis category, and length of stay were conducted for time to event analyses. RESULTS: Compared with the reference cohort, risks for subsequent hospitalization were increased in the CKD (hazard ratio=1.20, 99% confidence interval=1.18-1.23, P<0.001), dialysis (hazard ratio=1.76, 99% confidence interval=1.69-1.83, P<0.001), and kidney transplant (hazard ratio=1.85, 99% confidence interval=1.68-2.03, P<0.001) cohorts, with a mean follow-up time of 29 months. Similarly, risks for fatal hospitalization were increased for patients in the CKD (hazard ratio=1.41, 99% confidence interval=1.34-1.49, P<0.001), dialysis (hazard ratio=3.04, 99% confidence interval=2.78-3.31, P<0.001), and kidney transplant (hazard ratio=2.25, 99% confidence interval=1.67-3.03, P<0.001) cohorts. Risks for hospitalization and fatal hospitalization increased in a graded manner by CKD stage. CONCLUSIONS: Risks of subsequent hospitalization, including admission resulting in death, among patients with kidney disease were substantially increased in a large statewide population. Patients with kidney disease should be a focus of efforts to reduce hospitalizations and mortality.

AIMS: Small reference vessel diameter predicts adverse outcomes following coronary stenting. TAXUS Express and TAXUS Liberté paclitaxel-eluting stents (PES) reduce restenosis compared to bare metal stents (BMS) in small diameter vessels. TAXUS Element is a novel thin-strut, platinum chromium stent designed to enhance visibility, conformability, and drug delivery in small diameter vessels. METHODS AND RESULTS: The PERSEUS Small Vessel (SV) prospective, single-arm, superiority trial evaluates the TAXUS Element PES in 224 subjects with target lesion length≤20 mm and vessel diameter≥2.25 to <2.75 mm, compared to 125 lesion-matched historical Express BMS control subjects from the TAXUS V trial. The primary endpoint was nine-month in-stent late loss. The secondary endpoint was 12-month target lesion failure (TLF) compared to a pre-specified performance goal (PG). Outcomes were analysed with and without propensity-score adjustment. TAXUS Element was superior to the Express BMS for late loss (0.38±0.51 versus 0.80±0.53 mm respectively; P<0.001), and TLF (7.3%) was significantly less than the 19.5% PG (P<0.001). No differences in mortality, myocardial infarction, or stent thrombosis were observed through 12 months. Results were similar after adjustment. CONCLUSIONS: PERSEUS SV supports the efficacy and safety of the platinum chromium, thin-strut TAXUS Element stent in small coronary vessels.
