Cardiovascular Diagnosis and Therapy

BACKGROUND: Pemafibrate is a potent selective peroxisome proliferator-activated receptor α modulator. Whether this agent favorable modulates atherosclerosis in vivo remains unknown. This is the first case report to evaluate serial changes of coronary atherosclerosis under pemafirate use in type 2 diabetic patients already taking a high-intensity statin. CASE DESCRIPTION: A 75-year-old gentleman was hospitalized due to peripheral artery disease, which was treated by endovascular treatment...

OBJECTIVE: This article reviews current practices and outcomes in endovascular thrombectomy techniques for the treatment of thrombosed arteriovenous grafts (AVGs) and fistulas (AVFs). BACKGROUND: Arteriovenous (AV) access allows patients with end-stage renal disease (ESRD) to receive hemodialysis. Thrombosis of AV access can lead to delay in hemodialysis or abandonment of access requiring dialysis catheter placement. Endovascular approach has become the preferred treatment option for thrombosed access over surgery...

Acupuncture has already been extensively utilized to treat high blood pressure (hypertension) in several nations. Nevertheless, the bibliometric research on the worldwide usage of acupuncture for hypertension is mostly unclear. As a result, our objective for the research aimed to investigate the present state as well as developments in the global usage of acupuncture on hypertension during the last 20 years using CiteSpace (5.8.R2). The Web of Science (WOS) database examined papers on acupuncture treatment of hypertension from 2002 to 2021...

Central venous occlusion is a common condition in certain patient populations, with significant associated morbidity. Symptoms range from mild arm swelling to respiratory distress and can be particularly troublesome in the end stage renal disease population when related to dialysis access and function. Crossing completely occluded vessels is often the most challenging step and various techniques exist to accomplish this. Traditionally, blunt and sharp recanalization techniques are used to cross occluded vessels and are described in detail...

BACKGROUND AND OBJECTIVE: Heart failure (HF) in the pediatric population is a multi-factorial process with a wide spectrum of etiologies and clinical manifestations, that are distinct from the adult HF population, with congenital heart disease (CHD) as the most common cause. CHD has high morbidity/mortality with nearly 60% developing HF during the first 12 months of life. Hence, early discovery and diagnosis of CHD in neonates is pivotal. Plasma B-type natriuretic peptide (BNP) is an increasingly popular clinical marker in pediatric HF, however, in contrast to adult HF, it is not yet included in pediatric HF guidelines and there is no standardized reference cut-off value...

Hemodialysis remains the most frequently chosen kidney replacement modality across the world. A well-functioning dialysis vascular access is critical to providing successful dialysis therapy. Despite its drawbacks, central venous catheter is commonly used as a vascular access to initiate hemodialysis therapy in acute and chronic settings. The growing recognition of providing patient centric care and per recommendations from the recently published Kidney Disease Outcome Quality Initiative (KDOQI) Vascular Access Guidelines, selecting the appropriate patient population for a central venous catheter placement involves implementing the End Stage Kidney Disease (ESKD) Life-Plan strategy...

BACKGROUND AND OBJECTIVE: Drug-coated balloons (DCBs) seek to inhibit restenosis in treated hemodialysis access lesions by delivering an anti-proliferative agent (paclitaxel) into the vessel wall. While DCBs have proven effective in the coronary and peripheral arterial vasculature, the evidence for their use in arteriovenous (AV) access has been less robust. In part two of this review, a comprehensive overview of DCB mechanisms, implementation, and design is provided, followed by an examination of the evidence basis for their use in AV access stenosis...

Lower limb vascular access (LLVA) should be considered for patients in whom upper extremity access has been exhausted. The decisional process around vascular access (VA) site selection should incorporate a patient centered approach that aligns with End Stage Kidney Disease life-plan as recently described in proffered in 2019 Vascular Access Guidelines. The current surgical approaches to LLVA can be divided into two main groups: (A) autologous arteriovenous fistulas (AVFs); (B) synthetic arteriovenous grafts (AVGs)...

End-stage kidney disease (ESKD) affects over 780,000 Americans and is associated with excess morbidity and premature death. Kidney disease health disparities are well-recognized, manifesting as ESKD overburden among racial and ethnic minority populations. Specifically, Black and Hispanic individuals have a 3.4-fold and 1.3-fold greater life risk of developing ESKD than their white counterparts. There is compelling evidence that communities of color have less opportunity to benefit from kidney-specific care throughout the course of their disease, from pre-ESKD, to ESKD home therapies and kidney transplantation...

Dialysis access interventions have undergone significant developments over the last few decades. Angioplasty has been the mainstay of therapy since the early interventions in the 1980s and 1990s, but poor long-term patency and early loss of access has led investigators to assess other devices to treat stenoses associated with dialysis access failure. Multiple retrospective studies of stents for treatment of stenoses that did not respond to angioplasty demonstrated that the long-term outcomes were not improved over angioplasty alone...

BACKGROUND: Ethnic and sex-based disparity in outcomes after out-of-hospital cardiac arrest (OHCA) may exist and could be due to social factors and inequality in care. We aimed to study whether ethnic and sex-based differences in out-of-hospital cardiac arrest outcomes occurred in a safety net hospital within the largest municipal healthcare system in the United States. METHODS: We conducted a retrospective cohort study of patients successfully resuscitated from an OHCA and brought to New York City Health + Hospitals/Jacobi, from January 2019 to September 2021...

For years, the elephant trunk (ET) technique has been applied to extended aortic arch pathology facilitating staged downstream open- or endovascular completion. The recent use of a stentgraft as so-called frozen ET enables even single-stage repair, or its use as a scaffold in an acutely or chronically dissected aorta. Hybrid prosthesis have since been introduced, available as either a 4-branch graft or a straight graft for reimplantation of the arch vessels using the classic island technique. Both techniques are known to have technical advantages and disadvantages in specific surgical scenarios...

BACKGROUND AND OBJECTIVE: The incidence of patients with end-stage renal disease (ESRD) and subsequent need for dialysis is continuously rising. The detailed preoperative planning and careful creation of a functioning access for hemodialysis as a bridge to transplant or as a long-term solution, has a crucial role to reduce vascular access associated morbidity and mortality and improve quality of life of the ESRD patient population. In addition to a detailed medical workup including physical exam, a variety of imaging modalities exist to support further decision making with regard to the best suited vascular access for each individual patient...

Patients with end-stage renal disease (ESRD) often will ultimately require dialysis to survive. One type of dialysis is peritoneal dialysis (PD), which utilizes the vessel-rich peritoneum as a semi-permeable membrane to filter blood. In order to perform PD, a tunneled catheter must be placed through the abdominal wall and into the peritoneal space, with ideal positioning of the catheter within the most dependent portion of the pelvis, represented by the rectouterine or rectovesical space in women and men, respectively...

With the increasing life expectancy of patients with end-stage kidney disease, the creation and maintenance of hemodialysis vascular access are becoming more challenging. A comprehensive patient evaluation including a complete history, physical examination, and ultrasonographic vessel assessment is the foundation of the clinical evaluation. A patient-centered approach acknowledges the myriad of factors that impact the selection of optimal access for the distinct clinical and social circumstance of each patient...

The rise in prevalence of end stage renal disease (ESRD) and the impact on health care resulted in increasing focus on delivery of vascular access. Hemodialysis vascular access is the most common renal replacement therapy method. The vascular access types include arteriovenous fistula, arteriovenous graft, and tunneled central venous catheters. Vascular access function remains an important outcome measure with significant impact on morbidity and health care cost. The survival and quality of life of patients on hemodialysis is dependent on the adequacy of dialysis through proper vascular access...

BACKGROUND: Bicuspid aortic valve (BAV) disease leads to deviant helical flow patterns especially in the mid-ascending aorta (AAo), potentially causing wall alterations such as aortic dilation and dissection. Among others, wall shear stress (WSS) could contribute to the prediction of long-term outcome of patients with BAV. 4D flow in cardiovascular magnetic resonance (CMR) has been established as a valid method for flow visualization and WSS estimation. The aim of this study is to reevaluate flow patterns and WSS in patients with BAV 10 years after the initial evaluation...

BACKGROUND: Infective endocarditis (IE) is associated with high morbidity and mortality. Following an initial negative transesophageal echocardiogram (TEE), high clinical suspicion warrants repeat examination. We evaluated the diagnostic performance of contemporary TEE imaging for IE. METHODS: This retrospective cohort study included patients ≥18 years old undergoing ≥2 TEEs within 6 months, with confirmed diagnosis of IE based on Duke criteria, 70 in 2011 and 172 in 2019, were included...
