Our study aimed to assess the influence of incorporating new oral anticoagulant (NOAC) therapy on clinical outcomes among patients who underwent endovascular intervention for below-the-knee (BTK) occlusions necessitating reintervention. The inclusion criteria encompassed patients with chronic limb-threatening ischemia (CLTI) and had undergone a successful endovascular intervention for BTK artery occlusion, necessitating reintervention. Patients who underwent endovascular interventions for BTK reocclusion were compared to those who received dual-pathway inhibition with NOAC (rivaroxaban 2...

INTRODUCTION: Several studies have addressed technical aspects of endovascular thrombectomy (EVT), but it is not well known how procedural factors contribute to technical success in routine healthcare. The aim was to explore factors associated with technically successful EVT on nationwide scale. METHODS: We did an observational register-based study assessing factors associated with technical success off anterior circulation EVT in Sweden. The main outcome was successful recanalization defined as modified treatment in cerebral ischemia score 2b-3...

Introduction Obesity is a pandemic causing a significant burden on healthcare systems and carries increased morbidity and mortality. One of the options for managing obesity is endoscopic intragastric balloon (IGB) insertion. The aim of the study is to assess the efficacy, tolerance, and side effects of IGB insertion in overweight and obese patients. Methods This is a cross-sectional retrospective study that includes 71 patients who underwent IGB insertion from 2015 to 2019 at King Hamad University Hospital (KHUH), Kingdom of Bahrain...

Several regression-based models for predicting outcomes after acute myocardial infarction (AMI) have been developed. However, prediction models that encompass diverse patient-related factors over time are limited. This study aimed to develop a machine learning-based model to predict longitudinal outcomes after AMI. This study was based on a nationwide prospective registry of AMI in Korea ( n  = 13,104). Seventy-seven predictor candidates from prehospitalization to 1 year of follow-up were included, and six machine learning approaches were analyzed...

UNLABELLED: Takotsubo cardiomyopathy (TCM) is characterized by transient left ventricular dysfunction with apical ballooning, usually observed in postmenopausal women after a stressful event. We discuss a rare presentation of TCM induced by thyrotoxicosis secondary to Graves' disease. This case raises interesting questions about the pathogenesis, diagnosis, and management of TCM. LEARNING OBJECTIVES: 1. To recognize hyperthyroidism as a possible etiology of takutsubo cardiomyopathy...

UNLABELLED: Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome (ACS), which typically occurs in women at low risk of atherosclerosis. We herein report a case of SCAD in a 57-year-old man who later developed Takayasu arteritis. The patient presented to our hospital complaining of chest pain and was diagnosed with unstable angina. Emergent coronary angiography was performed, and optical coherence tomography revealed that ACS was caused by SCAD. The patient was treated medically without further ballooning or stenting...

UNLABELLED: An 89-year-old man with symptomatic severe aortic stenosis underwent transcatheter aortic valve implantation due to old age and a history of coronary artery bypass grafting. Computed tomography showed a tricuspid aortic valve and severe calcification at the aortic valve annulus, with a perimeter of 88.7 mm. The 34-mm Evolut PRO+ (Medtronic Inc., Minneapolis, MN, USA) was selected. After balloon aortic valvuloplasty, deployment of the Evolut PRO+ was attempted, but significant expansion failure was observed...

Subclavian artery injuries during internal jugular vein puncture when attempting central venous catheter insertion are rare. A 60-year-old man undergoing treatment for neuromyelitis optica with paralysis and sensory loss developed a complication during catheter placement into his right internal jugular vein for plasmapheresis. His previous physician felt resistance and discontinued the procedure. The patient later developed mild dyspnea and dysphagia. Computed tomography scans indicated thrombus formation and tracheal deviation...

Recently, resuscitative endovascular balloon occlusion of the aorta (REBOA) had been introduced as an innovative procedure for severe hemorrhage in the abdomen or pelvis. We aimed to investigate risk factors associated with mortality after REBOA and construct a model for predicting mortality. This multicenter retrospective study collected data from 251 patients admitted at five regional trauma centers across South Korea from 2015 to 2022. The indications for REBOA included patients experiencing hypovolemic shock due to hemorrhage in the abdomen, pelvis, or lower extremities, and those who were non-responders (systolic blood pressure (SBP) < 90 mmHg) to initial fluid treatment...

The occurrence of in-stent restenosis (ISR) poses a significant challenge for percutaneous coronary intervention (PCI). Thus, the promotion of vascular reendothelialization is essential to inhibit endothelial proliferation. In this study, we clarified the mechanism by which Detoxification and Activating Blood Circulation Decoction (DABCD) promotes vascular reendothelialization to avoid ISR by miRNA-126-mediated modulation of the vascular endothelial growth factor (VEGF) signaling pathway. A rat model of post-PCI restenosis was established by balloon injury...

BACKGROUND: Dysfunction of the left ventricular (LV) apex (apical variant) is the most common form in Takotsubo syndrome (TS). Several less common non-apical variants have been described - mid-ventricular, basal and focal. We hypothesised that the clinical presentation, and electrocardiographic (ECG) findings may vary between apical and non-apical TS. METHODS: We prospectively identified 194 consecutive patients with TS presenting to Middlemore Hospital, Auckland and obtained clinical, echocardiography, coronary angiography, and long-term follow-up data...

Visceral hypersensitivity resulting from compromised gut barrier with activated immune system is a key feature of irritable bowel syndrome (IBS). Corticotropin-releasing factor (CRF) and Toll-like receptor 4 (TLR4) activate proinflammatory cytokine signaling to induce these changes, which is one of the mechanisms of IBS. As activation of the NLRP3 inflammasome by lipopolysaccharide (LPS) or TLR4 leads to release interleukin (IL)-1β, the NLRP3 inflammasome may be involved in the pathophysiology of IBS...

Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) may be useful in treating exsanguinating trauma patients. This study seeks to compare rates of success, complications and time required for vascular access between ultrasound-guidance and surgical cut-down for femoral sheath insertion as a prospective observational case control study. Participating clinicians from either trauma surgery or anesthesiology were allocated to surgical cut-down or percutaneous ultrasound-guided puncture on a 1:1 ratio...

Homeowners in coastal environments often augment their access to estuarine ecosystems by building private docks on their personal property. Despite the commonality of docks, particularly in the Southeastern United States, few works have investigated their historical development, their distribution across the landscape, or the environmental justice dimensions of this distribution. In this study, we used historic aerial photography to track the abundance and size of docks across six South Carolina counties from the 1950s to 2016...

OBJECTIVES: Predicting whether balloon atrial septostomy (BAS) will be necessary after birth for fetuses with d-transposition of the great arteries (d-TGA) remains challenging. We sought to determine whether measurements obtained during fetal maternal hyperoxygenation (MH) testing can improve our ability to predict need for postnatal BAS. METHODS: Forty-one mothers carrying fetuses with d-TGA with either intact ventricular septum or small ventricular septal defect measuring <3mm underwent MH testing between 33-38 weeks gestation...

BACKGROUND: In this study, we aimed at clarifying the usefulness of drug-coated balloon catheters (DCBs) for arteriovenous fistulas (AVFs) that repeatedly undergo restenosis over a short period and to examine the factors that influence the patency period after DCB use. METHODS: This retrospective observational study was conducted using IN.PACT AV in 29 cases of AVFs with repeated restenosis within approximately 3 months, and temporary patency before and after DCB use in the same patients was compared...

PURPOSE: The aim of this study was to determine if postprocedural peripheral fractional flow reserve (pFFR) is associated with patency one year after drug-coated balloon (DCB) angioplasty for femoropopliteal (FP) lesions. MATERIALS AND METHODS: Forty-five consecutive patients having 49 de novo FP lesions were enrolled in this prospective, observational study conducted from April 2022 to Aug 2023. The pFFR was measured under hyperemic conditions after the administration of 30 mg of papaverine...

BACKGROUND: Candidates for transcatheter aortic valve replacement (TAVR) occasionally have a "borderline-size" aortic annulus between 2 transcatheter heart valve sizes, based on the manufacturer's sizing chart. Data on TAVR outcomes in such patients are limited. METHODS: We retrospectively reviewed 1816 patients who underwent transfemoral-TAVR with balloon-expandable valve (BEV) at our institution between 2016 and 2020. We divided patients into borderline and non-borderline groups based on computed tomography-derived annular measurements and compared outcomes...
