Considerations for cardiac catheterization laboratory procedures during the COVID-19 pandemic perspectives from the Society for Cardiovascular Angiography and Interventions Emerging Leader Mentorship (SCAI ELM) Members and Graduates.

The novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is highly infectious, carries significant morbidity and mortality, and has rapidly resulted in strained health care system and hospital resources. In addition to patient-related care concerns in infected individuals, focus must also relate to diminishing community spread, protection of staff, case selection, and concentration of resources. The current document based on available data and consensus opinion addresses appropriate catheterization laboratory preparedness for treating these patients, including procedure-room readiness to minimize external contamination, safe donning and doffing of personal protective equipment (PPE) to eliminate risk to staff, and staffing algorithms to minimize exposure and maximize team availability.

Thirty-Day Outcomes of Transcatheter Mitral Valve Replacement for Degenerated Mitral Bioprostheses (Valve-in-Valve), Failed Surgical Rings (Valve-in-Ring), and Native Valve With Severe Mitral Annular Calcification (Valve-in-Mitral Annular Calcification) in the United States: Data From the Society of Thoracic Surgeons/American College of Cardiology/Transcatheter Valve Therapy Registry.

Background: Transcatheter mitral valve replacement using aortic transcatheter heart valves has recently become an alternative for patients with degenerated mitral bioprostheses, failed surgical repairs with annuloplasty rings or severe mitral annular calcification who are poor surgical candidates. Outcomes of these procedures are collected in the Society of Thoracic Surgeons/American College of Cardiology/Transcatheter Valve Therapy Registry. A comprehensive analysis of mitral valve-in-valve (MViV), mitral valve-in-ring (MViR), and valve-in-mitral annular calcification (ViMAC) outcomes has not been performed.

Outcomes of Transcatheter Aortic Valve Replacement in Patients With Bicuspid Aortic Valve Disease: A Report From the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry.

Background: Patients with bicuspid aortic valve (AV) stenosis were excluded from the pivotal evaluations of transcatheter AV replacement (TAVR) devices. We sought to evaluate the outcomes of TAVR in patients with bicuspid AV stenosis in comparison with those with tricuspid AV stenosis.

Methods: We used data from the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry (November 2011 through November 2018) to determine device success, procedural outcomes, post-TAVR valve performance, and in-hospital clinical outcomes (mortality, stroke, and major bleeding) according to valve morphology (bicuspid versus tricuspid).

Retrograde Chronic Total Occlusion Percutaneous Coronary Intervention via Saphenous Vein Graft.

Objectives: The aim of this study was to examine the use of saphenous vein grafts (SVGs) for retrograde crossing during chronic total occlusion (CTO) percutaneous coronary intervention (PCI).

Background: The use of SVGs for retrograde crossing during CTO PCI has received limited study.

Methods: A total of 1,615 retrograde CTO PCIs performed between 2012 and 2019 at 25 centers were examined.

Takotsubo cardiomyopathy and acute manic attack.

Takotsubo cardiomyopathy predominantly occurs in women, with a high incidence in patients with psychiatric diseases. We present a 64-year-old white woman with an acute manic episode complicated by rhabdomyolysis and takotsubo cardiomyopathy.

SCAI publications committee manual of standard operating procedures.

Evidence-based recommendations for clinical practice are intended to help health care providers and patients make decisions, minimize inappropriate practice variation, promote effective resource use, improve clinical outcomes, and direct future research. The Society for Cardiovascular Angiography and Interventions (SCAI) has been engaged in the creation and dissemination of clinical guidance documents since the 1990s. These documents are a cornerstone of the society's education, advocacy, and quality improvement initiatives.

Assessing the risk of an anomalous circumflex artery using balloon aortic valvuloplasty prior to transcatheter aortic valve replacement.

Anomalous origin of the left circumflex coronary artery from the right sinus of Valsalva or proximal right coronary artery (RCA) is a well-known anatomic variation. Although the condition is usually benign, there is risk for compression of the anomalous artery by a prosthetic valve in patients undergoing aortic valve replacement (AVR). In more recent years, balloon aortic valvuloplasty (BAV) has been performed prior to transcatheter aortic valve replacement (TAVR) to serve as a diagnostic tool in the evaluation of symptom relief and procedural risks prior to definitive therapy with TAVR.

The Impact of Peripheral Artery Disease in Chronic Total Occlusion Percutaneous Coronary Intervention (Insights From PROGRESS-CTO Registry).

The impact of peripheral artery disease (PAD) in patients undergoing chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has received limited study. We reviewed 3999 CTO PCIs performed in 3914 patients between 2012 and 2018 at 25 centers, 14% of whom had a history of PAD. We compared the clinical and angiographic characteristics and procedural outcomes of patients with versus without history of PAD.

Outcomes of subintimal plaque modification in chronic total occlusion percutaneous coronary intervention.

Background: When crossing into the distal true lumen fails during chronic total occlusion (CTO) percutaneous coronary intervention (PCI), subintimal plaque modification (SPM) is often performed to restore antegrade flow and facilitate subsequent lesion recanalization.

Methods: Between January 2012 and May 4, 2019, 4,659 CTO PCIs were included in the PROGRESS-CTO registry, of which 935 (20%) had a prior unsuccessful attempt. Of those 935 patients, 119 (13%) had prior SPM.

Prospective Evaluation of a Blood Transfusion Protocol for Patients Undergoing Cardiac Operations.

Background: The Society of Thoracic Surgeons clinical practice guidelines recommend the creation of an interdisciplinary blood management team to implement protocols for improved blood transfusion practices. We report our center's prospective evaluation of a blood transfusion protocol.

Methods: An interdisciplinary blood management team developed protocols for transfusion of packed red blood cells, fresh frozen plasma, platelets, and cryoprecipitate.

Postcoronary Artery Bypass Graft Atrial Fibrillation Event Count and Survival: Differences by Sex.

Background: New-onset atrial fibrillation (AF) after coronary artery bypass graft surgery (CABG) is associated with poor outcomes, but data on the effects of its characteristics are lacking and conflicting. We examined the effect number of post-CABG AF events has on long-term mortality risk, and whether this is sex dependent.

Methods: Routinely collected Society of Thoracic Surgeons (STS) data were supplemented with details on new-onset post-CABG AF (detected in-hospital by continuous electrocardiogram/telemetry monitoring) and long-term survival for 9203 consecutive patients with isolated-CABG (2002-2010).

Impact of Aortic Atherosclerosis Burden on Outcomes of Surgical Aortic Valve Replacement.

Background: Epiaortic ultrasound detects and localizes ascending aortic atherosclerosis. In this analysis we investigated the association between epiaortic ultrasound-based atheroma grade during surgical aortic valve replacement (SAVR) and perioperative adverse outcomes.

Methods: SAVR patients in a randomized trial of 2 embolic protection devices underwent a protocol-defined 5-view epiaortic ultrasound read at a core laboratory.

Impact of concomitant treatment of non-chronic total occlusion lesions at the time of chronic total occlusion intervention.

Background: During chronic total occlusion (CTO) percutaneous coronary intervention (PCI), sometimes non-CTO lesions are also treated.

Methods: We compared the clinical and procedural characteristics and outcomes of CTO PCIs with and without concomitant treatment of a non-CTO lesion in a contemporary multicenter CTO registry.

Results: Of the 3598 CTO PCIs performed at 21 centers between 2012 and 2018, 814 (23%) also included PCI of at least one non-CTO lesion.

Pivotal Clinical Study to Evaluate the Safety and Effectiveness of the MANTA Percutaneous Vascular Closure Device.

Background: Open surgical closure and small-bore suture-based preclosure devices have limitations when used for transcatheter aortic valve replacement, percutaneous endovascular abdominal aortic aneurysm repair, or percutaneous thoracic endovascular aortic aneurysm repair. The MANTA vascular closure device is a novel collagen-based technology designed to close large bore arteriotomies created by devices with an outer diameter ranging from 12F to 25F. In this study, we determined the safety and effectiveness of the MANTA vascular closure device.

Transcatheter Valve Repair for Patients With Mitral Regurgitation: 30-Day Results of the CLASP Study.

Objectives: The authors report the procedural and 30-day results of the PASCAL Transcatheter Valve Repair System (Edwards Lifesciences, Irvine, California) in patients with mitral regurgitation (MR) enrolled in the multicenter, prospective, single-arm CLASP study.

Background: Severe MR may lead to symptoms, impaired quality of life, and reduced functional capacity when untreated.

Methods: Eligible patients had grade 3+ or 4+ MR despite optimal medical therapy and were deemed appropriate for the study by the local heart team.

Postoperative atrial fibrillation: Sex-specific characteristics and effect on survival.

Background: We sought to fill important gaps in the existing evidence regarding new-onset atrial fibrillation (AF) after coronary artery bypass graft surgery (CABG) by comparing the incidence, characteristics, and effect on long-term survival between men and women.

Methods: Nine thousand two hundred three consecutive patients without preoperative AF underwent isolated CABG from 2002 to 2010 at 3 US academic medical centers and 1 high-volume specialty cardiac hospital. Detailed data on CABG AF events detected via continuous in-hospital electrocardiogram/telemetry monitoring were supplemented with Society of Thoracic Surgeons data, and survival data, censored at October 31, 2011, using a copy of the Social Security Death Master File archived before state-owned data were removed (November 1, 2011).

Thoracic endovascular stent graft repair for ascending aortic diseases.

Objectives: We describe the preliminary results of thoracic endovascular aortic repair (TEVAR) in a group of patients with ascending aortic disease from the Global Registry for Endovascular Aortic Treatment (GREAT).

Methods: We identified TEVAR performed for diseases truly originating from the ascending aorta. Between July 2011 and May 2015, 5014 patients were enrolled; six (0.

Racial Disparities in the Utilization and Outcomes of TAVR: TVT Registry Report.

Objectives: This study sought to evaluate racial disparities in the performance and outcomes of transcatheter aortic valve replacement (TAVR).

Background: Racial disparities in cardiovascular diseases are well described. Whether the racial disparities observed in surgical aortic valve replacement also exist with TAVR remains unknown.

Community-Acquired Acute Kidney Injury as a Risk Factor of de novo Heart Failure Hospitalization.

Objectives: Because patients with hospital-acquired acute kidney injury (AKI) are at risk for subsequent development of heart failure (HF) and little is known about the relation between community-acquired AKI (CA-AKI) and HF, we sought to determine if CA-AKI is a risk factor for incident HF hospitalization.

Methods: We utilized Baylor Scott & White Health databases at the primary care and inpatient hospitalization levels to identify adults without a prior history of HF who had 2 or more serum creatinine measurements within 13 months in the primary care setting. We defined CA-AKI as a serum creatinine increase ≥0.

Hospital Resource Utilization Before and After Transcatheter Aortic Valve Replacement: The STS/ACC TVT Registry.

Background: Patients with severe aortic stenosis (AS) have repeat hospitalizations for multiple conditions.

Objectives: The purpose of this study was to assess the effect of transcatheter aortic valve replacement (TAVR) on hospitalizations in severe AS.

Methods: Using data from the Society of Thoracic Surgeons/American College of Cardiology TVT (Transcatheter Valve Therapy) registry with linkage to Medicare claims, the authors examined rates of all-cause, cardiovascular, and noncardiovascular hospitalizations and hospital days, as well as inpatient costs in the year pre-TAVR and post-TAVR.

In-Hospital Outcomes of Chronic Total Occlusion Percutaneous Coronary Interventions in Patients With Prior Coronary Artery Bypass Graft Surgery.

Background: We examined the procedural outcomes of chronic total occlusions (CTO) percutaneous coronary interventions in patients with prior coronary artery bypass graft surgery (CABG).

Methods And Results: We compared the clinical, angiographic characteristics and outcomes of 3486 CTO interventions performed in patients with (n=1101) and without (n=2317) prior CABG at 21 centers. Prior CABG patients (32% of total cohort) were older (67±9 versus 63±10 years; P<0.
