RESUMEN
BACKGROUND: Geographic cohorting is a hospital admission structure in which every patient on a given physician team is admitted to a dedicated hospital unit. Little is known about the long-term impact of this admission structure on patient outcomes and resident satisfaction. OBJECTIVE: To evaluate the effect of geographic cohorting on patient outcomes and resident satisfaction among inpatient internal medicine teaching services within an academic hospital. DESIGN AND INTERVENTION: We conducted an interrupted time series analysis examining patient outcomes before and after the transition to geographic cohorting of our 3 inpatient teaching services within a 520-bed academic hospital in November 2017. The study observation period spanned from January 2017 to October 2018, allowing for a 2-month run-in period (November-December 2017). PARTICIPANTS: We included patients discharged from the inpatient teaching teams during the study period. We excluded patients admitted to the ICU and observation admissions. MAIN MEASURES: Primary outcome was 6-month mortality adjusted for patient age, sex, race, insurance status, and Charlson Comorbidity Index (CCI) analyzed using a linear mixed effects model. Secondary outcomes included hospital length of stay (LOS), 7-day and 30-day readmission rate, Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) scores, and resident evaluations of the rotation. KEY RESULTS: During the observation period, 1720 patients (mean age 64, 53% female, 56% white, 62% Medicare-insured, mean CCI 1.57) were eligible for inclusion in the final adjusted model. We did not detect a significant change in 6-month mortality, LOS, and 7-day or 30-day readmission rates. HCAHPS scores remained unchanged (77 to 80% top box, P = 0.19), while resident evaluations of the rotation significantly improved (mean overall score 3.7 to 4.0, P = 0.03). CONCLUSIONS: Geographic cohorting was associated with increased resident satisfaction while achieving comparable patient outcomes to those of traditional hospital admitting models.

Cardiovascular disease (CVD) remains the leading cause of death in the United States. However, percutaneous interventional cardiovascular therapies are often underutilized in Blacks, Hispanics, and women and may contribute to excess morbidity and mortality in these vulnerable populations. The Society for Cardiovascular Angiography and Interventions (SCAI) is committed to reducing racial, ethnic, and sex-based treatment disparities in interventional cardiology patients. Accordingly, each of the SCAI Clinical Interest Councils (coronary, peripheral, structural, and congenital heart disease [CHD]) participated in the development of this whitepaper addressing disparities in diagnosis, treatment, and outcomes in underserved populations. The councils were charged with summarizing the available data on prevalence, treatment, and outcomes and elucidating potential reasons for any disparities. Given the huge changes in racial and ethnic composition by age in the United States (Figure 1), it was difficult to determine disparities in rates of diagnosis and we expected to find some racial differences in prevalence of disease. For example, since the average age of patients undergoing transcatheter aortic valve replacement (TAVR) is 80 years, one may expect 80% of TAVR patients to be non-Hispanic White. Conversely, only 50% of congenital heart interventions would be expected to be performed in non-Hispanic Whites. Finally, we identified opportunities for SCAI to advance clinical care and equity for our patients, regardless of sex, ethnicity, or race.

OBJECTIVES: Grit, defined as passion and perseverance for long-term goals, has been associated with the avoidance of burnout among residents in a number of specialties. We aimed to evaluate the relationship between grit and burnout among first-year Internal Medicine residents. METHODS: During the 2018-2019 academic year, the authors recruited 75 first-year Internal Medicine residents within a large academic program to complete the Short Grit Scale (Grit-S) and the Maslach Burnout Inventory General Survey (MBI-GS) at baseline and after 6 and 12 months. The primary outcome was the association between baseline Grit-S and MBI-GS scores within the domains of emotional exhaustion (EE) or cynicism (CYN) over time using linear mixed models. Secondary outcomes included the association between grit and high burnout at 6 or 12 months, grit and persistently high burnout, and the association of baseline high burnout with later high scores at 6 and 12 months using logistic regression models and trends in grit over time using repeated-measures analysis of variance. RESULTS: A total of 53 of 75 (71%) first-year residents completed the Grit-S and MBI-GS at baseline and at least one other time point. There was no association between grit and EE (P = 0.44) or CYN (P = 0.61) burnout domain scores. High baseline EE and high baseline CYN significantly increased the odds of later high burnout scores within each domain (EE odds ratio 9.66, 95% confidence interval 1.16-80.83; CYN odds ratio 13.37, 95% confidence interval 1.52-117.75). Grit scores and professional efficacy scores remained stable throughout the year (P = 0.15 and 0.46, respectively), while EE and CYN significantly increased (both P < 0.01). CONCLUSIONS: In this single-center study, grit was not associated with burnout among first-year Internal Medicine residents; however, our findings highlight the value of baseline burnout scores in helping to identify first-year residents who may be at higher risk of later burnout.

We sought to demonstrate the safety of ambulation of patients with intra-aortic balloon pumps (IABPs) inserted via the femoral approach in the setting of 1 cardiovascular surgical intensive care unit and 1 cardiac care unit. We studied 70 patients who had received femoral IABPs at our institution between December 2015 and June 2019 and who met standardized criteria for ambulation. These patients underwent initial standing trials with a specialty standing bed/tilt table and progressed to standing exercises and, ultimately, to ambulation (defined as covering a distance of at least 10 feet) with the physical therapist. A total of 323 sessions of ambulation were successfully performed in 70 patients with IABPs inserted via the femoral approach, for an average of 4.61 sessions per patient. The average ambulation session time was 45 minutes (3-62 minutes, covering a median distance of 420 ft [805 IQR]). Complications were defined as major or minor and were monitored for during and after ambulation. Major complications included limb ischemia, arterial dissection, aortic aneurysm, balloon rupture, significant hemodynamic compromise, and death. Minor complications included balloon migration, infection, paresthesia, changes in balloon augmentation, and hematoma at insertion site. No major complications were associated with ambulation, and only 11 minor complications were observed. The total complication rate was 3.40% for all ambulation sessions. Ambulation of selected patients with femoral IABPs appears to be a safe activity when using the enclosed protocol and selection process. Future studies are required to show that such activities decrease muscle deconditioning in these patients and enhance recovery.

BACKGROUND: No data exist comparing outcome prediction from arm exercise vs pharmacologic myocardial perfusion imaging (MPI) stress test variables in patients unable to perform treadmill exercise. METHODS: In this retrospective study, 2,173 consecutive lower extremity disabled veterans aged 65.4 ± 11.0years (mean ± SD) underwent either pharmacologic MPI (1730 patients) or arm exercise stress tests (443 patients) with MPI (n = 253) or electrocardiography alone (n = 190) between 1997 and 2002. Cox multivariate regression models and reclassification analysis by integrated discrimination improvement (IDI) were used to characterize stress test and MPI predictors of cardiovascular mortality at ≥10-year follow-up after inclusion of significant demographic, clinical, and other variables. RESULTS: Cardiovascular death occurred in 561 pharmacologic MPI and 102 arm exercise participants. Multivariate-adjusted cardiovascular mortality was predicted by arm exercise resting metabolic equivalents (hazard ratio [HR] 0.52, 95% CI 0.39-0.69, P < .001), 1-minute heart rate recovery (HR 0.61, 95% CI 0.44-0.86, P < .001), and pharmacologic and arm exercise delta (peak-rest) heart rate (both P < .001). Only an abnormal arm exercise MPI prognosticated cardiovascular death by multivariate Cox analysis (HR 1.98, 95% CI 1.04-3.77, P < .05). Arm exercise MPI defect number, type, and size provided IDI over covariates for prediction of cardiovascular mortality (IDI = 0.074-0.097). Only pharmacologic defect size prognosticated cardiovascular mortality (IDI = 0.022). CONCLUSIONS: Arm exercise capacity, heart rate recovery, and pharmacologic and arm exercise heart rate responses are robust predictors of cardiovascular mortality. Arm exercise MPI results are equivalent and possibly superior to pharmacologic MPI for cardiovascular mortality prediction in patients unable to perform treadmill exercise.

The ROX Coupler is a stented arterial-venous anastomosis intended for implantation in the external iliac artery and vein. Prior studies of the ROX Coupler show that it increases cardiac output, oxygen delivery, and decreases systemic vascular resistance, thereby lowering blood pressure. Clinical data for the ROX Coupler demonstrates significant reduction in blood pressure but proximal venous stenoses have been seen post-implantation requiring treatment.

Successful endovascular intervention for femoral-popliteal (FP) arterial disease provides relief of claudication and offers limb-salvage in cases of critical limb ischemia. Technologies and operator technique have evolved to the point where we may now provide effective endovascular therapy for a spectrum of lesions, patients, and clinical scenarios. Endovascular treatment of this segment offers a significant alternative to surgical revascularization, and may confer improved safety for a wide range of patients, not solely those deemed high surgical risk. Although endovascular therapy of the FP segment has historically been hampered by high rates of restenosis, emerging technologies including drug-eluting stents, drug-coated balloons, and perhaps bio-absorbable stent platforms, provide future hope for more durable patency in complex disease. By combining lessons learned from clinical trials, international trends in clinical practice, and insights regarding emerging technologies, we may appropriately tailor our application of endovascular therapy to provide optimal care to our patients. This document was developed to guide physicians in the clinical decision-making related to the contemporary application of endovascular intervention among patients with FP arterial disease.

OBJECTIVES: To assess the current use and application of simulators in interventional cardiology. BACKGROUND: Despite a paucity of data on the efficacy of simulation in medicine, cardiovascular simulation training is now a mandated part of cardiovascular fellowship training. Additionally, simulators have been endorsed by the Food and Drug Administration as a way to teach physicians new and novel procedures. We sought to establish the current use of simulators in cardiovascular medicine. METHODS: A systematic review was done of available training programs, and currently existing data regarding simulation training. A panel of experts was convened to review this data and provide recommendations as how simulation should be used in the field of interventional cardiology. RESULTS: This document provides a comprehensive review of the current state of simulation and how we as a society must formulate well validated studies to more closely examine and explore how this technology can be further studied and validated. CONCLUSIONS: Simulation will likely take on a larger role in cardiovascular training and maintenance of certification, but at the current time lacks a large body of evidence for its use.

Aorto-iliac arterial occlusive disease is common and may cause a spectrum of chronic symptoms from intermittent claudication to critical limb ischemia. Treatment is indicated for symptoms that have failed lifestyle and medical therapies or occasionally to facilitate other interventional procedures such as TAVR and/or placement of hemodynamic assist devices. It is widely accepted that TASC A, B, and C lesions are best managed with endovascular intervention. In experienced hands, most TASC D lesions may be treated by endovascular methods, and with the development of chronic total occlusion devices, many aorto-iliac occlusions may be recanalized safely by endovascular means. Interventional cardiologists should be well versed in the anatomy, as well as the treatment of aorto-iliac disease, given their need to traverse these vessels during transfemoral procedures. Overall, aorto-iliac occlusive disease is more commonly being treated with an endovascular-first approach, using open surgery as a secondary option. This document was developed to guide physicians in the clinical decision-making related to the contemporary application of endovascular intervention among patients with aorto-iliac arterial disease.

Background: Despite advances in therapy options, pulmonary embolism (PE) continues to carry a high risk of mortality and morbidity. Currently, therapeutic options are limited with only 2 US Food and Drug Administration-cleared catheter-based embolectomy devices approved for the treatment of intermediate-risk PE. The novel Helo PE thrombectomy catheter (Endovascular Engineering, Inc) has a flexible and collapsible funnel with an internal agitator for a dual mechanism of treatment for acute PE. We sought to investigate the safety and feasibility of the novel Helo PE thrombectomy catheter in intermediate-risk PE. Methods: A prospective, single-arm feasibility study evaluating the Helo PE catheter was performed in patients presenting with intermediate-risk PE. Patients underwent preprocedural and postprocedural computed tomography angiography. Primary efficacy was the difference in preprocedural to postprocedural right ventricle/left ventricle (RV/LV) ratio. Primary and secondary safety outcomes were all-cause mortality, major life-threatening bleeding, device-related serious adverse events, pulmonary or cardiac injury, and clinical decompensation at 48 hours postprocedure and at 30 days. Results: A total of 25 patients from 8 centers were consented and included in the analysis. Preprocedural computed tomography angiography revealed an RV/LV ratio of 1.53 ± 0.27. All patients underwent a successful thrombectomy procedure. Postprocedure, the RV/LV ratio was reduced to 1.15 ± 0.18, translating into a 23.2 ± 12.81% decrease from baseline. No patients underwent adjunctive thrombolysis. Two patients had adjunctive catheter-directed embolectomy with an alternative device. Two patients had postprocedural anemia requiring transfusion but did not meet criteria for major life-threatening bleeding by VARC-2 criteria. There were no major adverse events including no deaths, major bleeding, pulmonary injury, or vascular complications at 48 hours or 30 days post procedure. Conclusions: In this multicenter first-in-human study, use of the Helo PE thrombectomy catheter was feasible and safe for the treatment of acute PE.

Pulmonary embolism (PE) is a life-threatening condition with increasing hospital admissions. Prompt identification and treatment of PE patients with hemodynamic collapse are essential. Conflicting recommendations and weak evidence hinder effective management of PE, resulting in unchanged mortality rates despite advancements in therapies. Current risk stratification lacks granularity, necessitating a more detailed classification to guide treatment, predict outcomes, and improve patient selection for clinical trials. This article reviews clinical practice guidelines from major North American and European societies, emphasizing the need for more research and guidance to improve mortality and morbidity outcomes in PE.

Advocacy is a core mission of the Society for Cardiovascular Angiography & Interventions (SCAI). SCAI advocates on behalf of interventional cardiologists and our patients. This document provides foundational information and a toolkit for grassroots advocacy by interventional cardiologists. The first half of the document summarizes how health care laws are made, how medical devices are approved, and how procedure reimbursement is determined. The second half of the document is a playbook of advocacy strategies: legislative advocacy, judicial advocacy, advocacy with regulators and payors, advocacy in the media, and participation in SCAI advocacy initiatives, such as the Government Relations Committee and SCAI Political Action Committee. Equipped with this toolbox, interventional cardiologists must increase our advocacy activities with government, payors, and industry.
RESUMEN
Background: Interhospital transfer (IHT) of patients with acute life-threatening pulmonary embolism (PE) is necessary to facilitate specialized care and access to advanced therapies. Our goal was to understand what barriers and facilitators may exist during this transfer process from the perspective of both receiving and referring physicians. Methods: This qualitative descriptive study explored physician experience taking care of patients with life threatening PE. Subject matter expert physicians across several different specialties from academic and community United States hospitals participated in qualitative semi-structured interviews. Interview transcripts were subsequently analyzed using inductive qualitative description approach. Results: Four major themes were identified as barriers that impede IHT among patients with life threatening PE. Inefficient communication which mainly pertained to difficulty when multiple points of contact were required to complete a transfer. Subjectivity in the indication for transfer which highlighted the importance of physicians understanding how to use standardized risk stratification tools and to properly triage these patients. Delays in data acquisition were identified in regards to both obtaining clinical information and imaging in a timely fashion. Operation barriers which included difficulty finding available beds for transfer and poor weather conditions inhibiting transportation. In contrast, two main facilitators to transfer were identified: good communication and reliance on colleagues and dedicated team for transferring and treating PE patients. Conclusion: The most prominent themes identified as barriers to IHT for patients with acute life-threatening PE were: (1) inefficient communication, (2) subjectivity in the indication for transfer, (3) delays in data acquisition (imaging or clinical), and (4) operational barriers. Themes identified as facilitators that enable the transfer of patients were: (1) good communication and (2) a dedicated transfer team. The themes presented in our study are useful in identifying opportunities to optimize the IHT of patients with acute PE and improve patient care. These opportunities include instituting educational programs, streamlining the transfer process, and formulating a consensus statement to serve as a guideline regarding IHT of patients with acute PE.
RESUMEN
Background: Intravascular lithotripsy (IVL) for calcified lesion preparation prior to drug-eluting stent placement has high procedural success and safety, especially in women, whereas other atheroablative approaches are associated with increased procedural complications. We sought to investigate long-term sex-based outcomes of IVL-facilitated stenting. Methods: We performed a patient-level pooled analysis of the single-arm Disrupt CAD III and IV studies. Patient baseline, procedural characteristics, and outcomes were examined according to sex at 30 days and 1 year. The primary end point was major adverse cardiac events (a composite of cardiac death, all myocardial infarction, or target vessel revascularization). Target lesion failure was defined as cardiac death, target vessel myocardial infarction, or ischemia-driven target lesion revascularization. Results: A total of 448 patients, 106 (24%) women, were included. Women were older and less likely to be smokers. Women had smaller reference vessel diameters (2.8 mm vs 3.1 mm), shorter lesion length (23.6 mm vs 27.1 mm), and shorter total calcified length (44.4 mm vs 49.3 mm) compared with men. Post-IVL angiographic outcomes and complications were similar between women and men. At 1 year, major adverse cardiac event rates (12.3% vs 13.2%, P = .52) were not different between women and men. There were no differences between women and men (10.4% vs 11.2%; P = .43) in target lesion failure at 1 year. Conclusions: Use of IVL in the treatment of severely calcified lesions is associated with low rates of adverse clinical events and with similar safety and effectiveness in women and men at 1 year.
