Government Regulation and Percutaneous Coronary Intervention Volume, Access and Outcomes: Insights From the Washington State Cardiac Care Outcomes Assessment Program.

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.

Spontaneous coronary artery dissection and exogenous estrogen in a transgender female.

We report the case of a 37-year-old transgender patient with a history of orchiectomy on gender-affirming estrogen therapy who was hospitalized with an acute onset of chest pain with a resolution shortly after the presentation. On presentation, the patient had a rapid rise in troponin level and was urgently taken to the cardiac catheterization lab where spontaneous coronary artery dissection was diagnosed and treated with cutting balloon angioplasty and medical management. After a multidisciplinary discussion, the only notable risk factor was estrogen supplementation after gender reassignment surgery. To our knowledge, this is the only report of a male to female transgender patient reported to have spontaneous coronary artery dissection.

Cardiovascular Risk Assessment in the Older Athlete.

CONTEXT: Limited data are available to guide cardiovascular screening in adult or masters athletes (≥35 years old). This review provides recommendations and the rationale for the cardiovascular risk assessment of older athletes. EVIDENCE ACQUISITION: Review of available clinical guidelines, original investigations, and additional searches across PubMed for articles relevant to cardiovascular screening, risk assessment, and prevention in adult athletes (1990-2020). STUDY DESIGN: Clinical review. LEVEL OF EVIDENCE: Level 3. RESULTS: Atherosclerotic coronary artery disease (CAD) is the leading cause of exercise-induced acute coronary syndromes, myocardial infarction, and sudden cardiac death in older athletes. Approximately 50% of adult patients who experience acute coronary syndromes and sudden cardiac arrest do not have prodromal symptoms of myocardial ischemia. The risk of atherosclerotic cardiovascular disease (ASCVD) can be estimated by using existing risk calculators. ASCVD 10-year risk is stratified into 3 categories: low-risk (≤10%), intermediate-risk (between 10% and 20%), and high-risk (≥20%). Coronary artery calcium (CAC) scoring with noncontrast computed tomography provides a noninvasive measure of subclinical CAD. Evidence supports a significant association between elevated CAC and the risk of future cardiovascular events, independent of traditional risk factors or symptoms. Statin therapy is recommended for primary prevention if 10-year ASCVD risk is ≥10% (intermediate- or high-risk patients) or if the Agatston score is >100 or >75th percentile for age and sex. Routine stress testing in asymptomatic, low-risk patients is not recommended. CONCLUSION: We propose a comprehensive risk assessment for older athletes that combines conventional and novel risk factors for ASCVD, a 12-lead resting electrocardiogram, and a CAC score. Available risk calculators provide a 10-year estimate of ASCVD risk allowing for risk stratification and targeted management strategies. CAC scoring can refine risk estimates to improve the selection of patients for initiation or avoidance of pharmacological therapy.

Cover up: Clinic outcomes of covered stent usage for coronary perforation during PCI.

Coronary artery perforation is an uncommon, but potentially devastating, complication of PCI, and is observed most frequently in complex procedures. Clinical outcomes, including periprocedural and long-term mortality, are markedly worse with increasing degree of perforation. Perforation required covered stent usage predicts a high in-hospital and overall mortality, although no difference is noted between covered stent type.

ACC/AHA/ASE/HRS/ISACHD/SCAI/SCCT/SCMR/SOPE 2020 Appropriate Use Criteria for Multimodality Imaging During the Follow-Up Care of Patients With Congenital Heart Disease: A Report of the American College of Cardiology Solution Set Oversight Committee and Appropriate Use Criteria Task Force, American Heart Association, American Society of Echocardiography, Heart Rhythm Society, International Society for Adult Congenital Heart Disease, Society for Cardiovascular Angiography and Interventions, Society of Cardiovascular Computed Tomography, Society for Cardiovascular Magnetic Resonance, and Society of Pediatric Echocardiography.

The American College of Cardiology (ACC) collaborated with the American Heart Association, American Society of Echocardiography, Heart Rhythm Society, International Society for Adult Congenital Heart Disease, Society for Cardiovascular Angiography and Interventions, Society of Cardiovascular Computed Tomography, Society for Cardiovascular Magnetic Resonance, and the Society of Pediatric Echocardiography to develop Appropriate Use Criteria (AUC) for multimodality imaging during the follow-up care of patients with congenital heart disease (CHD). This is the first AUC to address cardiac imaging in adult and pediatric patients with established CHD. A number of common patient scenarios (also termed "indications") and associated assumptions and definitions were developed using guidelines, clinical trial data, and expert opinion in the field of CHD.1 The indications relate primarily to evaluation before and after cardiac surgery or catheter-based intervention, and they address routine surveillance as well as evaluation of new-onset signs or symptoms. The writing group developed 324 clinical indications, which they separated into 19 tables according to the type of cardiac lesion. Noninvasive cardiac imaging modalities that could potentially be used for these indications were incorporated into the tables, resulting in a total of 1,035 unique scenarios. These scenarios were presented to a separate, independent panel for rating, with each being scored on a scale of 1 to 9, with 1 to 3 categorized as "Rarely Appropriate," 4 to 6 as "May Be Appropriate," and 7 to 9 as "Appropriate." Forty-four percent of the scenarios were rated as Appropriate, 39% as May Be Appropriate, and 17% as Rarely Appropriate. This AUC document will provide guidance to clinicians in the care of patients with established CHD by identifying the reasonable imaging modality options available for evaluation and surveillance of such patients. It will also serve as an educational and quality improvement tool to identify patterns of care and reduce the number of Rarely Appropriate tests in clinical practice.

State-of-the-art percutaneous coronary interventions applied to the treatment of bifurcation lesions: Are we there yet?

Treatment of bifurcation lesions has advanced with the development of second-generation drug-eluting stents and state-of-the-art percutaneous coronary interventions techniques. This subanalysis of SYNTAX II demonstrates similar major adverse cardiac or cerebrovascular events in patients with bifurcation and nonbifurcation lesions, with a trend toward higher target lesion failure in the bifurcation cohort. The results, while compelling, require larger studies with longer follow-up, stratified by bifurcation strategy.

Uncommon but devastating: Stroke after percutaneous coronary intervention.

Stroke occurs infrequently following percutaneous coronary intervention (PCI) with 30-day and 1-year cumulative incidence of 0.4 and 1.5%, respectively. Patient comorbidities, acute presentations, and complex coronary lesions are more prevalent among patients who sustain a stroke. The occurrence of stroke is associated with higher short-term and overall mortality compared with bleeding or myocardial infarction.

Shading operators from the Gray: Are novel radiation barriers or changing physician behaviors the best next step?

Lead barriers to reduce operator radiation exposure in the catheterization laboratory are effective. This study of a novel vertical radiation shield suggests significant reduction in operator radiation exposure when used in addition to standard protection methods. Although additional barriers may help reduce radiation exposure, further education and training of operators in radiation safety may be as effective and perhaps more effective than additional barriers.

Members cooperate in the advancement of knowledge and education through research, publication, study, and teaching in the fields of cardiovascular disease. This summary reflects the proceedings from the recent scientific meeting to assess current clinical problems and propose future directions and possible solutions.

Robotic PCI: Evolving from novel toward non-inferior.

Robotic-assisted PCI appears to be safe and feasible in both simple and complex lesions. In this small cohort study, analysis of manual versus robotic PCI suggests comparable clinical outcomes. Further adequately powered, randomized, multicenter studies are needed to definitively evaluate outcomes in manual versus robotic-assisted PCI.

HAS-BLED for predicting transfemoral transcatheter aortic valve replacement outcomes: Enough to tamponade the problem?

As indications for TAVR expand, there is a need for predictive models of procedural complications. Application of the HAS-BLED score demonstrated patient comorbidities that contribute to increased bleeding events and mortality. Further adequately powered studies will be needed to validate the HAS-BLED score for use in the TAVR population or further elucidate important risk factor to incorporate into future predictive risk models.

ACC/AATS/AHA/ASE/ASNC/HRS/SCAI/SCCT/SCMR/STS 2019 Appropriate Use Criteria for Multimodality Imaging in the Assessment of Cardiac Structure and Function in Nonvalvular Heart Disease: A Report of the American College of Cardiology Appropriate Use Criteria Task Force, American Association for Thoracic Surgery, American Heart Association, American Society of Echocardiography, American Society of Nuclear Cardiology, Heart Rhythm Society, Society for Cardiovascular Angiography and Interventions, Society of Cardiovascular Computed Tomography, Society for Cardiovascular Magnetic Resonance, and the Society of Thoracic Surgeons.

This document is the second of 2 companion appropriate use criteria (AUC) documents developed by the American College of Cardiology, American Association for Thoracic Surgery, American Heart Association, American Society of Echocardiography, American Society of Nuclear Cardiology, Heart Rhythm Society, Society for Cardiovascular Angiography and Interventions, Society of Cardiovascular Computed Tomography, Society for Cardiovascular Magnetic Resonance, and Society of Thoracic Surgeons. The first document1 addresses the evaluation and use of multimodality imaging in the diagnosis and management of valvular heart disease, whereas this document addresses this topic with regard to structural (nonvalvular) heart disease. While dealing with different subjects, the 2 documents do share a common structure and feature some clinical overlap. The goal of the companion AUC documents is to provide a comprehensive resource for multimodality imaging in the context of structural and valvular heart disease, encompassing multiple imaging modalities. Using standardized methodology, the clinical scenarios (indications) were developed by a diverse writing group to represent patient presentations encountered in everyday practice and included common applications and anticipated uses. Where appropriate, the scenarios were developed on the basis of the most current American College of Cardiology/American Heart Association Clinical Practice Guidelines. A separate, independent rating panel scored the 102 clinical scenarios in this document on a scale of 1 to 9. Scores of 7 to 9 indicate that a modality is considered appropriate for the clinical scenario presented. Midrange scores of 4 to 6 indicate that a modality may be appropriate for the clinical scenario, and scores of 1 to 3 indicate that a modality is considered rarely appropriate for the clinical scenario. The primary objective of the AUC is to provide a framework for the assessment of these scenarios by practices that will improve and standardize physician decision making. AUC publications reflect an ongoing effort by the American College of Cardiology to critically and systematically create, review, and categorize clinical situations in which diagnostic tests and procedures are utilized by physicians caring for patients with cardiovascular diseases. The process is based on the current understanding of the technical capabilities of the imaging modalities examined.

Long-term clinical observations for a biofunctionalized stent: Yet to deliver their theoretical benefits.

Endothelial progenitor cells (EPCs) may allow accelerated and functional endothelialization of stents, theoretically reducing late stent complications as well reducing the duration of DAPT. In a pilot study of 193 patients at high risk of target vessel failure (TVF), the Genous EPC capturing stent (ESC) and TAXUS Liberté paclitaxel-eluting second-generation stent (PES) were similar at 5-years. Events rates appear higher for ESC within the first-year followed by higher rate of complications for PES during years 2-5. A larger randomized multi-center trials powered for non-inferiority of ECS to PES is underway.

Looking for the bare necessities.

The authors suggest that the early durability of the CoreValve implant should not be in question based on the results of this modestly sized, but well-done postmortem observational study. Given the ever-expanding knowledge of valvular degeneration, one thing is clear: more research and study is needed before any routine change in clinical practice, such as change it antithrombotic therapy, can be recommended. Further autopsy studies of patients who die outside of typical healthcare settings and who have had a longer median implant time would aid greatly in furthering the understanding of the degeneration and natural history of bioprosthetic transcatheter heart valves.

Conscious sedation for TAVR: A wave of the future?

As indications for TAVR continue to grow, experienced centers strive to adopt further minimally invasive techniques and continue to improve outcomes. Meta-analysis of the available data demonstrate that conscious sedation is associated with decreased ICU and hospitalization time, and is not associated with decreased procedural efficacy or safety. Randomized Controlled clinical Trial data will be needed to confirm observational findings suggesting decreased mortality with conscious sedation versus general anesthesia.

ACC/AATS/AHA/ASE/EACTS/HVS/SCA/SCAI/SCCT/SCMR/STS 2017 Appropriate Use Criteria for the Treatment of Patients With Severe Aortic Stenosis: A Report of the American College of Cardiology Appropriate Use Criteria Task Force, American Association for Thoracic Surgery, American Heart Association, American Society of Echocardiography, European Association for Cardio-Thoracic Surgery, Heart Valve Society, Society of Cardiovascular Anesthesiologists, Society for Cardiovascular Angiography and Interventions, Society of Cardiovascular Computed Tomography, Society for Cardiovascular Magnetic Resonance, and Society of Thoracic Surgeons.

The American College of Cardiology collaborated with the American Association for Thoracic Surgery, American Heart Association, American Society of Echocardiography, European Association for Cardio-Thoracic Surgery, Heart Valve Society, Society of Cardiovascular Anesthesiologists, Society for Cardiovascular Angiography and Interventions, Society of Cardiovascular Computed Tomography, Society for Cardiovascular Magnetic Resonance, and Society of Thoracic Surgeons to develop and evaluate Appropriate Use Criteria (AUC) for the treatment of patients with severe aortic stenosis (AS). This is the first AUC to address the topic of AS and its treatment options, including surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR). A number of common patient scenarios experienced in daily practice were developed along with assumptions and definitions for those scenarios, which were all created using guidelines, clinical trial data, and expert opinion in the field of AS. The 2014 AHA/ACC guideline for the management of patients with valvular heart disease: a report of the American College of Cardiology/American Heart Association Task Force on Practice Guidelines(1) and its 2017 focused update paper (2) were used as the primary guiding references in developing these indications. The writing group identified 95 clinical scenarios based on patient symptoms and clinical presentation, and up to 6 potential treatment options for those patients. A separate, independent rating panel was asked to score each indication from 1 to 9, with 1-3 categorized as "Rarely Appropriate," 4-6 as "May Be Appropriate," and 7-9 as "Appropriate." After considering factors such as symptom status, left ventricular (LV) function, surgical risk, and the presence of concomitant coronary or other valve disease, the rating panel determined that either SAVR or TAVR is Appropriate in most patients with symptomatic AS at intermediate or high surgical risk; however, situations commonly arise in clinical practice in which the indications for SAVR or TAVR are less clear, including situations in which 1 form of valve replacement would appear reasonable when the other is less so, as do other circumstances in which neither intervention is the suitable treatment option. The purpose of this AUC is to provide guidance to clinicians in the care of patients with severe AS by identifying the reasonable treatment and intervention options available based on the myriad clinical scenarios with which patients present. This AUC document also serves as an educational and quality improvement tool to identify patterns of care and reduce the number of rarely appropriate interventions in clinical practice.
