Angioplasty

A congenital anomalous origin of the coronary artery is a rare cardiovascular malformation that includes the left circumflex artery arising from the right sinus of Valsalva (RSV), both coronary arteries arising from RSV, the left anterior descending (LAD) artery arising from the respiratory sinus arrhythmia, and a single coronary artery arising from the left sinus of Valsalva. We present the case of a 72-year-old patient presenting with chest pain to his local hospital while cycling. Troponin levels peaked from 90 to 360 ng/L, and electrocardiography showed normal sinus rhythm and left bundle branch block...

PATIENTS AND METHODS: Materials and Methods: The study included 64 patients who suffered an acute myocardial infarction and underwent PCI with balloon angioplasty and stenting of the infarct-related vessel in the acute period. The predictors of adverse cardiovascular events were assessed events during 1 year of observation...

Background : We conducted a systematic review and meta-analysis to examine the feasibility of paclitaxel-coated balloon (PCB) angioplasty for de novo lesions in patients with acute coronary syndrome (ACS) by comparing with drug-eluting stent (DES) placement. Methods : By a systematic literature search, nine (five randomized controlled, two retrospective propensity-score matched, and two retrospective baseline-balanced) studies comparing the midterm clinical and angiographic outcomes after PCB angioplasty and DES placement were included, yielding 974 and 1130 ACS cases in PCB and DES groups, respectively...

The aim of the study is to evaluate the safety and effectiveness of rotational atherectomy-assisted balloon angioplasty (BTK-RA) for the treatment of isolated below the knee (BTK) atherosclerotic lesions and to compare the outcomes to plain old balloon angioplasty (POBA). Between January 2020 and September 2023, 96 consecutive patients with chronic limb threatening ischemia (CTLI) and isolated BTK-lesions underwent POBA (group A) or BTK-RA (group B). The primary outcome measures were: periprocedural technical success, primary patency, postoperative increase of the ankle branchial index (ABI), target lesion revascularization (TLR), limb salvage, minor amputation and death...

BACKGROUND: Endovascular treatment devices require compatible guide catheters to navigate complex vessels and anatomy. The Fubuki XF Long Sheath guide catheter (Fubuki XF) was developed with a 0.090-inch internal diameter with hydrophilic coating, an atraumatic rounded tip, and enhanced trackability and support with gradual shaft transition zones. METHODS: We retrospectively analyzed a prospectively maintained database of neuroendovascular patients treated using Fubuki XF at our center (July 2022─May 2023)...

Balloon entrapment is a rare complication of angioplasty in calcified or recalcitrant lesions. A 65-year-old man with chronic limb-threatening ischemia underwent balloon angioplasty of his heavily calcified tibial arteries with a low-profile, tapered, compliant balloon. The balloon became entrapped within the posterior tibial artery and required multiple endovascular maneuvers to deflate and separate the balloon from the calcified arterial wall. This case report describes several adjunctive techniques for retrieval of an entrapped balloon in small, calcified arteries before consideration of surgical removal...

Although numerous case series and meta-analyses have shown the efficacy of venous sinus stenting (VSS) in the treatment of idiopathic intracranial hypertension and idiopathic intracranial hypertension-associated pulsatile tinnitus, there remain numerous challenges to be resolved. There is no widespread agreement on candidacy; pressure gradient and failed medical treatment are common indications, but not all clinicians require medical refractoriness as a criterion. Venous manometry, venography, and cerebral angiography are essential tools for patient assessment, but again disagreements exist regarding the best, or most appropriate, diagnostic imaging choice...

BACKGROUND: Endovascular treatment of severe intracranial atherosclerotic stenosis (ICAS) using coronary drug-eluting stents (DESs) significantly reduces the risk of in-stent restenosis (ISR) and stroke recurrence. However, there are few reports regarding the treatment of ICAS with intracranial dedicated DES. Herein, we present our experience with the feasibility, safety, and medium-term follow-up outcomes of a novel intracranial DES, named NOVA stent, in patients with symptomatic severe ICAS (≥70%)...

OBJECTIVE: The use of endovascular treatments for symptomatic intracranial atherosclerosis disease (ICAD) remains contentious due to high periprocedural complications. Many centers resort to general anesthesia for airway protection and optimal periprocedural conditions; however, this approach lacks real-time monitoring of patients' neurological status during procedures. In this study, we employed intracranial stenting with the Wingspan system under local anesthesia to address this challenge...

BACKGROUND Exploring the factors that impact the time from symptom onset to first medical contact (S2FMC) is crucial for improving outcomes in elderly patients diagnosed with acute ST-segment elevation myocardial infarction (STEMI). This study conducted a retrospective analysis on 282 patients who underwent emergency percutaneous coronary intervention (PCI) or percutaneous transluminal coronary angioplasty (PTCA) in Guangzhou City District to identify significant factors affecting S2FMC. MATERIAL AND METHODS A retrospective analysis was conducted on 282 patients with STEMI who underwent emergency percutaneous coronary intervention (PCI)...

BACKGROUND: The left pulmonary artery (LPA) may be kinked and stenotic, especially in tetralogy of Fallot, because of ductal tissue and anterior deviation of the conal septum. If LPA stenosis is not effectively treated during total correction, surgical angioplasty is occasionally performed. However, whether pulmonary artery (PA) angioplasty in adolescents or adults improves perfusion in the ipsilateral lung remains unclear. METHODS: This retrospective review enrolled patients who underwent PA angioplasty for LPA stenosis between 2004 and 2019...

OBJECTIVES: To evaluate the efficacy of rejoining mainstream and accessory veins for forced maturation of autogenous arteriovenous fistula (AVF) METHODS: Twenty-three patients who underwent forced maturation through vein rejoining between January 2018 and September 2022 were included. In cases where AVF maturation failure due to the presence of accessory veins, rejoining was primarily considered when distinguishing the main branch becomes challenging. This difficulty typically occurs when the sizes of the two vessels are nearly equal and the combined diameters of these veins exceed 6 mm...

OBJECTIVES: The utility and benefit of intravascular ultrasound (IVUS) has been well established in coronary interventions, however widespread adoption for peripheral interventions has lagged. The objectives of this review article were to discuss the technical components of IVUS, describe key learning pearls for IVUS utilization and review the literature describing the clinical outcomes of endovascular, peripheral arterial interventions using IVUS. METHODS: A scoping review of the current literature utilizing Pubmed...

For patients with Chronic Limb Threatening Ischemia (CLTI), endovascular approaches to revascularization are often employed as a component of multimodality care aimed at limb preservation. However, patients with CLTI are also prone to treatment failure, particularly following balloon angioplasty alone. Drug-coated devices utilizing Paclitaxel were developed to decrease restenosis but have been primarily studied in patients presenting with claudication. In recent years, data have emerged which describe the efficacy of drug-coated devices in the treatment of patients with CLTI...

PURPOSE: To investigate the safety and efficacy of large-bore uncovered stents for treating malignant superior vena cava syndrome. METHODS: This retrospective study included 115 patients (89 men, 26 women; mean age 63.2 years; range 21-83 years) who underwent endovascular large-bore (≥18 mm in diameter) uncovered stent placement between August 2015 and July 2022. One patient was lost to follow-up. Therefore, 114 patients were available for follow-up...

BACKGROUND: Although distal native fistula is the best first-line vascular access (VA), upper arm fistula (UAF) prevalence is increasing worldwide, except in Japan. Our previous survey on 50% of hemodialysis patients (HP) revealed a prevalence of UAF of less than 5%, which is lower than the findings published by the DOPPS 5 study in our country. We analyzed the VA prevalence on 100% of HPs from our department. METHODS: In December 2021, we investigated the prevalence of vascular access of 1295 hemodialysis patients from 17 dialysis factories...

BACKGROUND: Neurointerventionalists must pay close attention to multiple devices on multiple screens simultaneously, which can lead to oversights and complications. Artificial intelligence (AI) has potential application in recognizing and monitoring these devices on fluoroscopic imaging. METHODS: We report out preliminary experience with a real time AI assistance software, Neuro-Vascular Assist (iMed technologies, Tokyo, Japan), in six patients who underwent carotid artery stenting...

BACKGROUND: Measurement of cardiac troponin (cTn) by a high sensitivity method is now the recommended strategy for the detection of myocardial injury. An international survey was undertaken to assess how this has been implemented. METHODS: A questionnaire based around 14 domains on cardiac biomarkers was distributed electronically with the aid of professional societies accessed by a web link within the invitation. Results were returned electronically then extracted into a relational database for analysis...

AIMS: Many cardiovascular events occur in seemingly healthy individuals.We set out to assess the predictive value of atherosclerosis imaging in combination with cardiovascular risk calculators in subjects aged 40-65 years. METHODS: We compared PROCAM (PROspective CArdiovascular Münster study), SCORE (Systematic COronary Risk Evaluation) and SCORE2 with carotid ultrasound (total plaque area, TPA) in subjects without cardiovascular disease. In this prospective cohort study, follow-up was obtained by phone or mail from patients; or from clinical records, if needed...
