RESUMEN
Background: Acute coronary syndrome (ACS) hospital admissions decreased during the start of the COVID-19 outbreak. Information is limited on how Google searches were related to patients' behaviour during this time. Methods: We examined de-identified data from 2019 through 2020 regarding the following monthly items: (i) admissions for ACS from the Veterans Affairs Healthcare System; (ii) out-of-hospital cardiac arrest (OHCA) from the National Emergency Medical Services Information System (NEMSIS) public dataset; and (iii) Google searches for "chest pain," "coronavirus," "chest pressure," and "hospital safe" from Google Trends. We analyzed the trends for ACS admissions, OHCA, and Google searches. Results: During the early months of the first COVID-19 outbreak, the following occurred: (i) Veterans Affairs data showed a significant reduction in ACS admissions at a national and regional (Florida) level; (ii) the NEMSIS database showed a marked increase in OHCA at a national level; and (iii) Google Trends showed a significant increase in the before-mentioned Google searches at a national and regional level. Conclusions: ACS hospital admissions decreased during the beginning of the pandemic, likely owing to delayed healthcare utilization secondary to patients fear of acquiring a COVID-19 infection. Concordantly, the volume of Google searches for hospital safety and ACS symptoms increased, along with OHCA events, during the same time. Our results suggest that Google Trends may be a useful tool to predict patients' behaviour and increase preparedness for future events, but statistical strategies to establish association are needed.
Contexte: Les admissions à l'hôpital pour un syndrome coronarien aigu (SCA) ont diminué au début de la pandémie de COVID-19. Or, il existe peu de données sur les recherches effectuées par les patients dans Google pendant cette période. Méthodologie: Nous avons examiné des données mensuelles dépersonnalisées de 2019 à 2020 sur les éléments suivants : i) admissions pour un SCA dans le système de santé de Veterans Affairs aux États-Unis; ii) arrêts cardiaques extrahospitaliers (ACEH) de l'ensemble de données publiques du National Emergency Medical Services Information System (NEMSIS); et iii) les recherches dans Google selon Google Trends pour « chest pain ¼ (douleur thoracique), « coronavirus ¼, « chest pressure ¼ (oppression thoracique) et « hospital safe ¼ (sécurité dans les hôpitaux). Nous avons également analysé les tendances relatives aux admissions pour un SCA, aux ACEH et aux recherches dans Google. Résultats: Pour les premiers mois de la première vague de COVID-19, les observations sont les suivantes : i) les données de Veterans Affairs ont montré une réduction significative des admissions pour un SCA à l'échelle nationale et régionale (Floride); ii) la base de données du NEMSIS a montré une augmentation marquée des ACEH à l'échelle nationale; et iii) les tendances observées au moyen de Google Trends indiquent une augmentation significative à l'échelle nationale et régionale des recherches dans Google à l'aide des termes mentionnés précédemment. Conclusions: Les admissions à l'hôpital pour un SCA ont diminué au début de la pandémie, probablement en raison de la crainte des patients de contracter la COVID-19, qui les a amenés à repousser le recours à des soins de santé. Pendant la même période, le volume des recherches dans Google à propos de la sécurité dans les hôpitaux et les symptômes de SCA a augmenté, tout comme le nombre d'ACEH. Nos résultats semblent indiquer que Google Trends pourrait être un outil pratique pour prédire les comportements des patients et mieux se préparer aux événements futurs, mais il convient d'élaborer des stratégies statistiques permettant de mieux caractériser ces liens.
RESUMEN
A 67-year-old male presenting with an anterior ST-segment elevation myocardial infarction (STEMI) underwent stent placement in the left anterior descending coronary. The patient was discharged on an appropriate medical regimen containing dual antiplatelet therapy (DAPT). Four days later, the patient presented with repeat acute coronary syndrome symptomatology. Electrocardiogram demonstrated ongoing STEMI in the previously treated artery distribution. Emergency angiography revealed restenosis and total thrombotic occlusion. Post-intervention stenosis was 0% after aspiration thrombectomy and balloon angioplasty. Stent thrombosis is a high-mortality and therapeutically challenging condition requiring prepared clinicians who recognize predisposing risk factors and initiate early management.
RESUMEN
Transcatheter aortic valve replacement (TAVR) is well-established for severe symptomatic aortic stenosis (AS), but its use in rheumatic heart disease (RHD) has been limited. We systematically review the use of TAVR for severe symptomatic AS in RHD. Pubmed, Embase, and Scopus were searched for TAVR for symptomatic severe AS and proven or suspected RHD. Procedure characteristics, efficacy, and safety endpoints were collected and all definitions were based on the Valve Academic Research Consortium-2 (VARC-2) criteria. We included 3 case series and 12 case reports, with a total of 43 patients. Mean age was 76 years, 75% were female, and 85% had NYHA class III-IV symptoms. Follow up ranged from 1 to 29 months. Patients were moderate to high risk, with Society of Thoracic Surgery score ranging from 6.1% to 17.6%. The approach was transfemoral in 30 (83%) cases. Procedural success occurred in 37 (86%) patients. Of the 7 patients with periprocedural complications, 4 had valve dislodgement, 1 deployment failure, 1 unplanned cardiopulmonary bypass, and 1 moderate aortic regurgitation. Paravalvular leak was reported in 5 (11.6%) patients. Only 1 patient had heart block requiring pacemaker. Among 13 studies (23 patients), 30-day mortality was 0%. One case series with 19 patients had a 30-day, 1-year, 2-year, and 5-year mortality of 5%, 11%, 31%, and 48%, respectively. TAVR appears feasible for selected patients with rheumatic severe AS, albeit our results indicate a 14% incidence of device failure. Future randomized clinical trials may clarify the role of TAVR in this group.

Academic medicine as a practice model provides unique benefits to society. Clinical care remains an important part of the academic mission; however, equally important are the educational and research missions. More specifically, the sustainability of health care in the United States relies on an educated and expertly trained physician workforce directly provided by academic medicine models. Similarly, the research charge to deliver innovation and discovery to improve health care and to cure disease is key to academic missions. Therefore, to support and promote the growth and sustainability of academic medicine, attracting and engaging top talent from fellows in training and early career faculty is of vital importance. However, as the health care needs of the nation have risen, clinicians have experienced unprecedented demand, and individual wellness and burnout have been examined more closely. Here, we provide a close look at the unique drivers of burnout in academic cardiovascular medicine and propose system-level and personal interventions to support individual wellness in this model.

AIMS: The aims of the Critical Care Cardiology Trials Network (CCCTN) are to develop a registry to investigate the epidemiology of cardiac critical illness and to establish a multicentre research network to conduct randomised clinical trials (RCTs) in patients with cardiac critical illness. METHODS AND RESULTS: The CCCTN was founded in 2017 with 16 centres and has grown to a research network of over 40 academic and clinical centres in the United States and Canada. Each centre enters data for consecutive cardiac intensive care unit (CICU) admissions for at least 2 months of each calendar year. More than 20 000 unique CICU admissions are now included in the CCCTN Registry. To date, scientific observations from the CCCTN Registry include description of variations in care, the epidemiology and outcomes of all CICU patients, as well as subsets of patients with specific disease states, such as shock, heart failure, renal dysfunction, and respiratory failure. The CCCTN has also characterised utilization patterns, including use of mechanical circulatory support in response to changes in the heart transplantation allocation system, and the use and impact of multidisciplinary shock teams. Over years of multicentre collaboration, the CCCTN has established a robust research network to facilitate multicentre registry-based randomised trials in patients with cardiac critical illness. CONCLUSION: The CCCTN is a large, prospective registry dedicated to describing processes-of-care and expanding clinical knowledge in cardiac critical illness. The CCCTN will serve as an investigational platform from which to conduct randomised controlled trials in this important patient population.

Pericardial decompression syndrome, a rare but potentially fatal complication following pericardiocentesis, is defined as paradoxical hemodynamic deterioration. The exact pathophysiology is unknown, but it is likely that several mechanisms involving hemodynamic, ischemic, and autonomic imbalance play a role. There is no specific treatment; however, early supportive interventions should be implemented. (Level of Difficulty: Intermediate.).
RESUMEN
BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has impacted many aspects of ST-segment elevation myocardial infarction (STEMI) care, including timely access to primary percutaneous coronary intervention (PPCI). OBJECTIVES: The goal of the NACMI (North American COVID-19 and STEMI) registry is to describe demographic characteristics, management strategies, and outcomes of COVID-19 patients with STEMI. METHODS: A prospective, ongoing observational registry was created under the guidance of 3 cardiology societies. STEMI patients with confirmed COVID+ (group 1) or suspected (person under investigation [PUI]) (group 2) COVID-19 infection were included. A group of age- and sex-matched STEMI patients (matched to COVID+ patients in a 2:1 ratio) treated in the pre-COVID era (2015 to 2019) serves as the control group for comparison of treatment strategies and outcomes (group 3). The primary outcome was a composite of in-hospital death, stroke, recurrent myocardial infarction, or repeat unplanned revascularization. RESULTS: As of December 6, 2020, 1,185 patients were included in the NACMI registry (230 COVID+ patients, 495 PUIs, and 460 control patients). COVID+ patients were more likely to have minority ethnicity (Hispanic 23%, Black 24%) and had a higher prevalence of diabetes mellitus (46%) (all p < 0.001 relative to PUIs). COVID+ patients were more likely to present with cardiogenic shock (18%) but were less likely to receive invasive angiography (78%) (all p < 0.001 relative to control patients). Among COVID+ patients who received angiography, 71% received PPCI and 20% received medical therapy (both p < 0.001 relative to control patients). The primary outcome occurred in 36% of COVID+ patients, 13% of PUIs, and 5% of control patients (p < 0.001 relative to control patients). CONCLUSIONS: COVID+ patients with STEMI represent a high-risk group of patients with unique demographic and clinical characteristics. PPCI is feasible and remains the predominant reperfusion strategy, supporting current recommendations.

BACKGROUND: Biological considerations suggest that renin-angiotensin system inhibitors might influence the severity of COVID-19. We aimed to evaluate whether continuing versus discontinuing renin-angiotensin system inhibitors (angiotensin-converting enzyme inhibitors or angiotensin receptor blockers) affects outcomes in patients admitted to hospital with COVID-19. METHODS: The REPLACE COVID trial was a prospective, randomised, open-label trial done at 20 large referral hospitals in seven countries worldwide. Eligible participants were aged 18 years and older who were admitted to hospital with COVID-19 and were receiving a renin-angiotensin system inhibitor before admission. Individuals with contraindications to continuation or discontinuation of renin-angiotensin system inhibitor therapy were excluded. Participants were randomly assigned (1:1) to continuation or discontinuation of their renin-angiotensin system inhibitor using permuted block randomisation, with allocation concealed using a secure web-based randomisation system. The primary outcome was a global rank score in which participants were ranked across four hierarchical tiers incorporating time to death, duration of mechanical ventilation, time on renal replacement or vasopressor therapy, and multiorgan dysfunction during the hospitalisation. Primary analyses were done in the intention-to-treat population. The REPLACE COVID trial is registered with ClinicalTrials.gov, NCT04338009. FINDINGS: Between March 31 and Aug 20, 2020, 152 participants were enrolled and randomly assigned to either continue or discontinue renin-angiotensin system inhibitor therapy (continuation group n=75; discontinuation group n=77). Mean age of participants was 62 years (SD 12), 68 (45%) were female, mean body-mass index was 33 kg/m2 (SD 8), and 79 (52%) had diabetes. Compared with discontinuation of renin-angiotensin system inhibitors, continuation had no effect on the global rank score (median rank 73 [IQR 40-110] for continuation vs 81 [38-117] for discontinuation; ß-coefficient 8 [95% CI -13 to 29]). There were 16 (21%) of 75 participants in the continuation arm versus 14 (18%) of 77 in the discontinuation arm who required intensive care unit admission or invasive mechanical ventilation, and 11 (15%) of 75 participants in the continuation group versus ten (13%) of 77 in the discontinuation group died. 29 (39%) participants in the continuation group and 28 (36%) participants in the discontinuation group had at least one adverse event (χ2 test of adverse events between treatment groups p=0·77). There was no difference in blood pressure, serum potassium, or creatinine during follow-up across the two groups. INTERPRETATION: Consistent with international society recommendations, renin-angiotensin system inhibitors can be safely continued in patients admitted to hospital with COVID-19. FUNDING: REPLACE COVID Investigators, REPLACE COVID Trial Social Fundraising Campaign, and FastGrants.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for coronavirus disease 2019 (COVID-19), is associated with high incidence of multiorgan dysfunction and death. Angiotensin-converting enzyme 2 (ACE2), which facilitates SARS-CoV-2 host cell entry, may be impacted by angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs), two commonly used antihypertensive classes. In a multicenter, international randomized controlled trial that began enrollment on March 31, 2020, participants are randomized to continuation vs withdrawal of their long-term outpatient ACEI or ARB upon hospitalization with COVID-19. The primary outcome is a hierarchical global rank score incorporating time to death, duration of mechanical ventilation, duration of renal replacement or vasopressor therapy, and multiorgan dysfunction severity. Approval for the study has been obtained from the Institutional Review Board of each participating institution, and all participants will provide informed consent. A data safety monitoring board has been assembled to provide independent oversight of the project.

Background Right ventricular systolic dysfunction (RVSD) is a known risk factor for adverse outcome in surgical aortic valve replacement. Transcatheter aortic valve replacement (TAVR), on the other hand, has been shown to be either beneficial or have no effect on right ventricular systolic function. However, the prognostic significance of RVSD on TAVR has not been clearly determined. We conducted a systematic review and meta-analysis to define the impact of RVSD on outcomes in terms of 1-year mortality in patients with severe aortic stenosis undergoing TAVR. Methods and Results An extensive literature review was performed, with an aim to identify clinical studies that focused on the prognosis and short-term mortality of patients with severe symptomatic aortic stenosis who underwent TAVR. A total of 3166 patients from 8 selected studies were included. RVSD, as assessed with tricuspid annular plane systolic excursion, fractional area change or ejection fraction, was found to be a predictor of adverse procedural outcome after TAVR (hazard ratio, 1.31; 95% CI, 1.1-1.55; P=0.002). Overall, we found that RVSD did affect post-TAVR prognosis in 1-year mortality rate. Conclusions Patients with severe, symptomatic aortic stenosis and concomitant severe RVSD have a poor 1-year post-TAVR prognosis when compared with patients without RVSD. Right ventricular dilation and severe tricuspid regurgitation were associated with increased 1-year morality post-TAVR and should be considered as independent risk factors. Further evaluations of long-term morbidity, mortality, as well as sustained improvement in functional class and symptoms need to be conducted to determine the long-term effects.

BACKGROUND: Pulseless ventricular tachycardia/ventricular fibrillation (VT/VF) is the initial rhythm in a third of in-hospital cardiac arrest patients. Mechanical circulatory support (MCS) device use remains poorly understood in this population. METHODS: We conducted an observational analysis of temporal trends in the utilization of MCS in VT/VF IHCA between January 2008 and December 2014 utilizing the Nationwide Inpatient Sample (NIS) database. Using multivariable analysis, we assessed factors associated with MCS use and survival to discharge. RESULTS: Among 151,628 hospitalizations with VT/VF IHCA, 14,981 (9.9%) received MCS. Intra-aortic balloon pump (IABP) was the most commonly used MCS (9.1%). From 2008 to 2014, there was significant increase in the utilization of MCS (8.7-11%; ptrend < 0.0001). On multivariable analysis, there was 12-fold increase and three-fold increase in the utilization of PVAD and ECMO respectively; however, there was no significant change in the use of IABP. Over the seven-year sample period, there was significant increase in the overall survival to hospital discharge (35.4-43.5%; ptrend < 0.0001). Survival to hospital discharge increased in both MCS and non-MCS groups. CONCLUSION: There was significant increase in utilization of MCS after VT/VF IHCA during the study period. IABP was the most commonly utilized MCS. The survival to hospital discharge increased in the overall study population including both MCS and non-MCS groups. Future studies are needed to identify patient population most likely to benefit from the use of MCS after VT/VF IHCA.

BACKGROUND: Despite improvements in acute care and survival after non-ST-elevation acute coronary syndrome (NSTE-ACS) hospitalization, early readmissions remain common, and have significant clinical and financial impact. OBJECTIVES: Determine the predictors and etiologies of 30-day readmissions in NSTE-ACS. METHOD: The study cohort was derived from the National Readmission Database 2014 identifying patients with a primary diagnosis of NSTE-ACS using ICD9 code. RESULTS: We identified a total of 300,269 patients admitted with NSTE-ACS; 13.4% were readmitted within 30-day. The most common cause of readmission was heart failure (HF) (15.6%), followed by a recurrent myocardial infarction (MI) (10%). Predictors of increased readmissions were age ≥ 75 years (OR: 1.34, 95% CI: 1.30-1.39), female gender (OR 1.12, 95% CI 1.09-1.16), a Charlson Comorbidity Index (CCI) >3 (OR 2.11, 95% CI: 2.04-2.18), ESRD (OR 2.01, 95% CI 1.89-2.14), CKD (OR: 1.58, 95% CI: 1.51-1.64), length of stay ≥5 days (OR: 1.51, 95% CI 1.46-1.56) and adverse events during the index admission such as AKI (OR:1.31, 95% CI: 1.25-1.36), major bleeding (OR:1.20, 95% CI: 1.12-1.24); whereas admission to a teaching hospital (OR 0.92, 95% CI 0.89-0.95) and PCI (OR 0.70, 95% CI 0.67-0.72) were associated with less likelihood of 30-day readmission. CONCLUSION: Readmission rate at 30-days is high among NSTE-ACS patients and the most common readmission etiologies are HF and recurrent MI. A CCI more than 3 and ESRD were the most significant predictors for readmission; patients undergoing PCI had less odds of readmission.

BACKGROUND: We examined the outcomes of older adults undergoing nontrans-femoral (non-TF) transcatheter aortic valve replacement (TAVR) procedures including trans-apical (TA), trans-aortic (TAo), trans-subclavian (TSub), and trans-carotid (TCa) techniques. METHODS AND RESULTS: This is an observational study of all consecutive older patients who underwent non-TF TAVR for symptomatic severe AS with Edwards Sapien (ES), Medtronic CoreValve, ES3 or Lotus Valve at three centers in France and the United States from 04/2008 to 02/2017. Baseline characteristics and clinical outcomes were defined according to VARC-2 criteria. Of 857 patients who received TAVR, 172 (20%) had an alternative access procedure. Of these, 45 (26%) were TA, 67 (39%) TAo, 17 (10%) TSub, and 43 (25%) TCa procedures. The preference for non-TF access site was different between the two countries (US: TA 39%, TAo 52%, TSub 9%; TCa 0% vs. France: TA 9%, TAo 23%, TSub 11%, and TCa 57%, P-value < .001). Most patients who underwent TAo TAVR were older women (median age: TA 82, TAo 84, TSub 81, TCa 81, P-value = 0.043; female gender: TA 32 (27%), TAo 30 (55%), TSub 10 (41%), TCa 27 (37%), P-value = .021). The predicted Society of Thoracic Surgery risk of mortality was similar among groups (TA 7%, TAo 7%, TSub 6%, TCa 7%, P-value= .738). No differences were observed in the frequency of para-valvular leak, intra-procedural bleeding, vascular complications, conversion to open-heart surgery, or development of acute kidney injury. The highest in-hospital mortality was observed in the TAo group (TA 2%, TAo 15%, TSub 0%, TCa 2%, P-value = .014). However, hospital length of stay, one-month, and one-year mortality were similar among non-TF techniques. CONCLUSION: Although regional differences exist in the choice of alternative access techniques, centers with high technical expertise can provide a safe alternative to traditional TF TAVR. TAo TAVR was associated with higher in-hospital mortality than other non-TF approaches, and this may have reflected patient rather than procedural factors. All alternative access techniques had similar mortality rates and clinical outcomes at one-year follow-up. Trans-carotid access is safe and feasible compared to other non-TF access techniques.

OBJECTIVE: This study sought to examine the trends and predictors of mechanical circulatory support (MCS) use in patients hospitalized after out-of-hospital cardiac arrest (OHCA). BACKGROUND: There is a paucity of data regarding MCS use in patients hospitalized after OHCA. METHODS: We conducted an observational analysis of MCS use in 960,428 patients hospitalized after OHCA between January 2008 and December 2014 in the Nationwide Inpatient Sample database. On multivariable analysis, we also assessed factors associated with MCS use and survival to discharge. RESULTS: Among the 960,428 patients, 51,863 (5.4%) had MCS utilized. Intra-aortic balloon pump (IABP) was the most commonly used MCS after OHCA with frequency of 47,061 (4.9%), followed by extracorporeal membrane oxygenation (ECMO) 3650 (0.4%), and percutaneous ventricular assist devices (PVAD) 3265 (0.3%). From 2008 to 2014, there was an increase in the utilization of MCS from 5% in 2008 to 5.7% in 2014 (P trendâ¯<â¯0.001). There was a non-significant decline in the use of IABP from 4.9% to 4.7% (P trendâ¯=â¯0.95), whereas PVAD use increased from 0.04% to 0.7% (P trendâ¯<â¯0.001), and ECMO use increased from 0.1% to 0.7% (P trendâ¯<â¯0.001) during the study period. Younger, male patients with myocardial infarction, higher co-morbid conditions, VT/VF as initial rhythm, and presentation to a large urban hospital were more likely to receive percutaneous MCS implantation. Survival to discharge was significantly higher in patients who were selected to receive MCS (56.9% vs. 43.1%, OR: 1.16, 95% CI: (1.11-1.21), pâ¯<â¯0.001). CONCLUSIONS: There is a steady increase in the use of MCS in OHCA, especially PVAD and ECMO, despite lack of randomized clinical trial data supporting an improvement in outcomes. More definitive randomized studies are needed to assess accurately the optimal role of MCS in this patient population.

INTRODUCTION: Transfemoral access (TFA) is widely used for coronary angiography and percutaneous coronary intervention (PCI). The influence of operator age, gender, experience, and procedural volume on performance of femoral arterial access has not been studied. METHODS: A survey instrument was developed and distributed via e-mail from professional societies to interventional cardiologists worldwide from March to December 2016. RESULTS: A total of 988 physicians from 88 countries responded to the survey. TFA is the preferred approach for patients with cardiogenic shock, left main or bifurcation PCI, and procedures with mechanical circulatory support. Older (<50years: 56.4%; ≥50years: 66.8%, p<0.0039) and high PCI volume operators (<100 PCI: 57.3%; 100-299 PCI: 58.7%; ≥300 PCI: 64.3%, p<0.134) preferred palpation only without imaging (fluoroscopy or ultrasound (US)) for TFA. Most respondents preferred not to use micropuncture needle to puncture the femoral artery. Older (≥50years: 64.4%; <50years: 71.5%, p<0.04) and high PCI volume operators (≥300 PCI: 64.1%; 100-299 PCI: 72.6%; <100 PCI: 67.9%, p<0.072) tended not to perform femoral angiography (FA). Of those performing FA, the majority opted to do it at the end of the procedure. CONCLUSION: Despite best practice guideline recommendations, older and high PCI volume interventional cardiologists prefer not to use imaging for femoral access or perform femoral angiography during TF procedures. These data highlight opportunities to further reduce TFA complications.

OBJECTIVES: The aim of this study was to examine the current practice and use of transfemoral approach (TFA) for coronary angiography and intervention. BACKGROUND: Wide variability exists in TFA techniques for coronary procedures. METHODS: The authors developed a survey instrument that was distributed via e-mail lists from professional societies to interventional cardiologists from 88 countries between March and December 2016. RESULTS: Of 987 operators, 18% were femoralists, 38% radialists, 42% both, and 2% neither. Access using femoral pulse palpation alone was preferred by 60% of operators, fluoroscopy guidance by 11%, and a combination of palpation, fluoroscopy, or ultrasound by 27%. Only 11% used micropuncture in >90% of their cases. Performing femoral angiography immediately after access was preferred by 23% and at the end of the procedure by 47%, and not done at all by 31% of operators. Hemostasis by manual compression was preferred by 50%, collagen plug vascular closure device by 31%, and suture-based vascular closure device by 11% of operators. Judkins left and right catheters were preferred for diagnostic angiography of the left (99%) and right (94%) coronary arteries. Extra backup curves (XB or EBU) were most commonly preferred for percutaneous coronary intervention of the left anterior descending (80%) and left circumflex (80%), whereas the Judkins right catheter was preferred for percutaneous coronary intervention of the right coronary artery (86%). CONCLUSIONS: There is significant variability in preferences for femoral access technique. Even though recommended best practices advocate for fluoroscopic and ultrasound guidance, most operators use palpation alone. Femoral angiography is also not consistently used despite guideline recommendations. The lack of adoption of imaging guidance for vascular access deserves further investigation.

INTRODUCTION: Impella is a catheter-based micro-axial flow pump placed across the aortic valve, and it is currently the only percutaneous left ventricular assist device approved for high-risk percutaneous coronary intervention and cardiogenic shock. Areas Covered: Even though several studies have repeatedly demonstrated the excellent hemodynamic profile of Impella in high-risk settings, it remains underutilized. Here we aim to provide an up-to-date summary of the available literature on Impellas use in High risk settings as well as the practical aspects of its usage. Expert Commentary: Percutaneous coronary interventions in high rsk settings have always been challenging for a physician. Impella 2.5 and CP, have been proven safe, cost effective and feasible in High Risk Percutaneous coronary Interventions with an excellent hemodynamic profile.

OBJECTIVE: To analyze trends in management and outcomes of patients infected with the human immunodeficiency virus (HIV) undergoing percutaneous coronary intervention (PCI) for an acute myocardial infarction (AMI) in the United States. BACKGROUND: Infection with HIV is an independent risk factor for accelerated atherosclerosis associated with higher rates of AMI. Current trends and outcomes of HIV-infected individuals presenting with AMI in the United States remain unknown. METHODS: Using the Healthcare Cost and Utilization Project National Inpatient Sample database we identified HIV-infected individuals who underwent PCI for an AMI from 2002 to 2013. Multivariable logistic regression and propensity-score matching were performed to analyze outcomes. RESULTS: We identified a total of 59 194 patients of which 7841 underwent PCI during index hospitalization (13.3%). Most patients were men (71%), ≥50 years of age (82%), and white (74%). ST-elevation myocardial infarction was present in 21% of cases. Charlson comorbidity index (CCI) was 5.67 ± 0.4. Predictors of post-procedural complications included female sex, black race, higher CCI, and placement of a bare metal stent, whereas predictors of mortality included occurrence of a complication, ST-elevation myocardial infarction, age ≥70 years, and higher CCI. Conversely, placement of a drug-eluting stent was associated with a reduced risk of complications and mortality. After propensity-score matching, HIV-infected individuals were less likely to undergo PCI and receive a drug-eluting stent, while having longer length of stay, higher hospitalization costs, and higher in-hospital mortality when compared to non-infected individuals. CONCLUSION: Significant disparities continue to affect HIV-infected individuals undergoing PCI for AMI in the United States.

Aortic regurgitation (AR) after transcatheter aortic valve replacement (TAVR) is associated with an increased risk of mortality. In severe cases, abrupt hemodynamic changes may occur with a sudden increase in left ventricular end-diastolic pressure that results in frank pulmonary edema, hypoxia, and cardiogenic shock. Here, the case is reported of a patient who developed severe AR immediately after valve deployment that led to severe hemodynamic compromise. The procedural techniques necessary for the immediate management of severe transvalvular and paravalvular AR are described.

OBJECTIVES: The aim of this study was to describe the contemporary incidence of chronic total occlusions (CTOs) and the success rates of CTO percutaneous coronary intervention (PCI), as well as the complications and long-term outcomes of these patients. BACKGROUND: The contemporary prevalence and management of coronary CTOs is understudied. METHODS: Consecutive veterans undergoing coronary angiography at 79 Veterans Affairs sites between 2007 and 2013 were examined. Detailed baseline clinical, angiographic, and follow-up outcomes were evaluated using national data from the Veterans Affairs Clinical Assessment Reporting and Tracking program. RESULTS: Among 111,273 patients with obstructive coronary artery disease, 29,399 (26.4%) had ≥1 CTO, most commonly in the right coronary artery distribution (n = 18,986 [64.6%]). Elective CTO PCI was attempted in 2,394 patients (8.1%), with a procedural success rate of 79.7%. The odds of CTO PCI success increased over the years of the study (odds ratio: 1.08; 95% confidence interval [CI]: 1.01 to 1.16; p = 0.03). Compared with failed CTO PCI, successful CTO PCI was associated with a decreased adjusted risk for mortality (hazard ratio: 0.67; 95% CI: 0.47 to 0.95; p = 0.02) and coronary artery bypass graft surgery (hazard ratio: 0.14; 95% CI: 0.08 to 0.24; p < 0.01) at 2 years but no significant change in the risk for hospitalization for myocardial infarction (hazard ratio: 0.89; 95% CI: 0.58 to 1.36; p = 0.58). CONCLUSIONS: Approximately 1 in 4 patients with obstructive coronary artery disease on coronary angiography had CTOs. Among patients who went on to elective CTO PCI, the success rate was 79.7%. Compared with failed CTO PCI, successful CTO PCI was associated with a decreased risk for mortality as well as a decreased need for subsequent coronary artery bypass graft surgery.
