Long-term risk of adverse limb outcomes in older patients after endovascular femoral artery revascularization: The Boston femoral artery endovascular revascularization outcomes (Boston FAROUT) study.

Introduction: Older patients may be denied endovascular revascularization of the superficial femoral artery (SFA) for peripheral artery disease (PAD) due to concerns of worse limb outcomes than younger patients.

Methods: We assessed adverse outcomes in patients after an index revascularization stratified by age (age < 65, 65-75 years, and > 75 years) from two centers between 2003 and 2011 and followed a median 9 (25 %-75 %: 7, 11) years. Outcomes included major adverse limb events (MALE) or minor repeat revascularization, death, and major adverse cardiac and cerebrovascular events (MACCE).

Long-Term Adverse Limb Events After Femoral Artery Endovascular Revascularization: The Boston FAROUT Study.

Background: : Patient, lesion, and procedural characteristics may impact the long-term risks of adverse limb outcomes differently after successful endovascular revascularization for lower extremity peripheral artery disease. The study objective was to assess the relationships of patient, lesion, and procedural characteristics to the subsequent risk of major and minor adverse limb events over the decade after successful endovascular revascularization of the superficial femoral artery for chronic limb-threatening ischemia (CLTI) or lifestyle-limiting claudication.

Methods: A retrospective cohort of patients who underwent endovascular revascularization between 2003-2011 were followed for a median of 9.

Directional growth of iron oxide nanowires on a vicinal copper surface.

Single-crystal magnetic nanostructures with well-defined shapes attract lots of interest due to their potential applications in magnetic and spintronic devices. However, development of methods allowing controlling their mutual crystallographic and geometric orientation constitutes a significant scientific challenge. One of the routes for obtaining such structures is to grow the materials epitaxially on naturally-structured supports, such as vicinal surfaces of single-crystal substrates.

Extracorporeal Femoro-Carotid Shunt for Transcarotid Transcatheter Aortic Valve Replacement.

Transcatheter aortic valve replacement may be performed with a transcarotid approach when peripheral vascular disease is prohibitive for transfemoral access. In this case, a patient who presented in cardiogenic shock secondary to severe aortic stenosis developed electroencephalographic changes during transcarotid TAVR. A temporary extracorporeal femoro-carotid shunt permitted successful TAVR.

Risk of Mortality Related to Recurrent Limb Events After Endovascular Revascularization of the Superficial Femoral Artery for Peripheral Artery Disease: The Boston Femoral Artery Endovascular Revascularization Outcomes (Boston FAROUT) Study.

Endovascular revascularization of the superficial femoral artery (SFA) may lead to recurrent ischemic syndromes, revascularization, or amputation. The impact of these events on mortality is unknown. We followed all patients having SFA endovascular revascularization for claudication or chronic limb-threatening ischemia in 2 cardiovascular (CV) divisions in Boston, Massachusetts.

Patient and limb outcomes 10 years after endovascular revascularization of the superficial femoral artery for peripheral artery disease: The Boston Femoral Artery Endovascular Revascularization Outcomes (Boston FAROUT) study.

Methods: We assessed outcomes in patients having endovascular revascularization of the superficial femoral artery in two centers between 2003 and 2011 and followed for a median 9.3 (25-75%: 6.

Improper ferroelastic phase transition in a hydrogen-bonded metallocyanide-based (azetidinium)(HO)[Co(CN)] framework.

A hydrogen-bonded metallocyanide-based (AZE)(HO)[Co(CN)] framework was obtained by introducing a hydronium cation to the AB(1)B(2)CN-type structure. Simple K/HO substitution exchange the three-dimensional structure of the double-perovskite into two-dimensional layers containing open inorganic cages with a strongly discontinuous improper ferroelastic phase transition.

Marital Status and Sex-Based Differences in Outcomes After Transcatheter Aortic Valve Implantation.

Studies have shown improved outcomes among married patients who underwent cardiovascular surgery; however, this has not been well studied in transcatheter aortic valve implantation (TAVi). We examined the impact of marital status and patient sex on outcomes after TAVi. Patients who underwent TAVi from January 2015 to June 2018 were reviewed and stratified into 3 groups: single, married, and widowed.

Acute Myocardial Infarction Within 24 Hours After COVID-19 Vaccination.

COVID-19 vaccination was launched in the United States in mid-December 2020. There are limited data on the risk of thrombotic events related to COVID-19 vaccines. In conclusion, we report 2 cases of acute myocardial infarction with onset <24 hours after the first dose of a COVID-19 vaccine in patients presenting with shoulder pain.

Role of Cardiac CT in Pre-Procedure Planning for Transcatheter Mitral Valve Replacement.

Objectives: This study sought to evaluate cardiac computed tomography (CCT) findings and their clinical impact among patients being considered for transcatheter mitral valve replacement (TMVR).

Background: CCT is used to evaluate whether patients are candidates for TMVR, but limited data exist on the yield of such tests.

Methods: Patients referred for pre-procedural CCT for TMVR planning in the context of failing mitral bioprosthetic valves, annuloplasty rings, and severe native valve disease with annular calcification were included in this study.

A step-by-step guide to transseptal valve-in-valve transcatheter mitral valve replacement.

With the recent success of transcatheter aortic valve replacement (TAVR), transcatheter options for the management of mitral valve pathology have also gained considerable attention. Valve-in-valve (ViV) transcatheter mitral valve replacement (TMVR) is one such technique that has emerged as a safe and effective therapeutic option for patients with degenerated mitral valve bioprostheses at high-risk for repeat surgical mitral valve replacement. Several access strategies, including trans-apical, transseptal, trans-jugular, and trans-atrial access have been described for ViV-TMVR.

Short-Term Outcomes of Transcatheter Versus Isolated Surgical Aortic Valve Replacement for Mediastinal Radiation-Associated Severe Aortic Stenosis.

Background: Surgical aortic valve replacement (SAVR) is associated with adverse outcomes in patients with radiation-associated aortic stenosis. Transcatheter aortic valve replacement (TAVR) may improve outcomes in this population.

Methods: We evaluated 1668 TAVR and 2611 patients with SAVR enrolled in the Society of Thoracic Surgeons' database between 2011 and 2018.

A step-by-step guide to trans-axillary transcatheter aortic valve replacement.

The application of transcatheter aortic valve replacement (TAVR) has expanded rapidly over the last decade as a less invasive option for the treatment of severe aortic stenosis. In order to perform successful TAVR, vascular access must be obtained with a large-bore catheter to deliver the transcatheter valve to the aortic annulus. Several techniques have been developed for this purpose including transfemoral (TF), trans-aortic, trans-apical, trans-caval, trans-carotid, and trans-axillary (TAx) with varying degrees of success.

Magnetic reversal in perpendicularly magnetized antidot arrays with intrinsic and extrinsic defects.

Defects can significantly affect performance of nanopatterned magnetic devices, therefore their influence on the material properties has to be understood well before the material is used in technological applications. However, this is experimentally challenging due to the inability of the control of defect characteristics in a reproducible manner. Here, we construct a micromagnetic model, which accounts for intrinsic and extrinsic defects associated with the polycrystalline nature of the material and with corrugated edges of nanostructures.

Ion induced ferromagnetism combined with self-assembly for large area magnetic modulation of thin films.

A highly versatile and scalable path to obtain buried magnetic nanostructures within alloy thin films, while maintaining a flat topography, is described. A magnetic pattern of nanoscale periodicity is generated over ∼cm2 areas by employing a B2 → A2 structural transition in the prototype Fe60Al40 thin alloy films. The phase transition was induced in the confined regions via ion-irradiation through self-assembled nanosphere masks.

Comparison of Sex-Based Differences in Home or Nonhome Discharge Utilization of Rehabilitative Services and Outcomes Following Transcatheter Aortic Valve Implantation in the United States.

Sex-based differences in outcomes have been shown to affect caregiving in medical disciplines. Increased spending due to postacute care transfer policies has led hospitals to further scrutinize patient outcomes and disposition patterns after inpatient admissions. We examined sex-based differences in rehabilitative service utilization after transcatheter aortic valve implantation (TAVI).

ACC/AHA/SCAI/SIR/SVM 2018 Appropriate Use Criteria for Peripheral Artery Intervention: A Report of the American College of Cardiology Appropriate Use Criteria Task Force, American Heart Association, Society for Cardiovascular Angiography and Interventions, Society of Interventional Radiology, and Society for Vascular Medicine.

The American College of Cardiology (ACC) collaborated with the American Heart Association, Society for Cardiovascular Angiography and Interventions, Society of Interventional Radiology, and Society for Vascular Medicine, along with several ACC Councils, to establish and evaluate Appropriate Use Criteria (AUC) for peripheral artery intervention (PAI). Although PAI has been the subject of prior single-society papers, this is the first multisocietal effort on the topic. To initiate the AUC process, patient scenarios that are common in clinical practice were drafted, along with assumptions and definitions for those scenarios.
