Background: Lower torso hemorrhage is a significant cause of death from injuries in combat. Resuscitative endovascular balloon occlusion of the aorta (REBOA) has been used to rescue patients successfully in the hospital setting, but its prehospital use is controversial. We designed a device that would be easy to use, safer in injured vessels, migration-resistant and amenable to a prehospital environment. Methods: We designed a novel, balloon-led device using common commercial materials...

The number of patients with atrial fibrillation currently referred for catheter ablation is increasing. However, the number of trained operators and the capacity of many electrophysiology labs are limited. Accordingly, a steeper learning curve and technical advances for efficient and safe ablation are desirable. During the last decades several catheter-based ablation devices have been developed and adapted to improve not only lesion durability, but also safety profiles, to shorten procedure time and to reduce radiation exposure...

INTRODUCTION: The incidence of placenta accreta (PA) has markedly increased in the United States, from 1/30 000 in 1950 to 1/731 deliveries in 2011. Although placenta praevia after prior caesarean sections (CS) is the most important risk factor for PA, other risk factors make up 1-5% of PA occurrences. At our referral hospital, we use the pre-caesarean prophylactic balloon catheter with or without post-surgery embolisation in a hybrid room. Here, we evaluate the role of prior CS and placenta praevia on the outcome of this procedure...

Introduction: Symptomatic intracranial hemorrhage represents one of the most feared complications of endovascular reperfusion. We aim to describe a series of patients that experienced immediate reperfusion injury with active intraprocedural extravasation within the territory of the deep penetrating arteries and provide real-time correlation with CT "spot sign." Methods: This was a retrospective analysis of patients that suffered reperfusion injury with active arterial extravasation during endovascular stroke treatment in two tertiary care centers...

Background: Treatment of large vessel occlusion acute ischemic stroke with mechanical thrombectomy has become the standard of care after recent clinical trials. However, the degree of recanalization with stent retrievers remains very important in overall outcomes. We sought to review the utility of a new balloon guide catheter (BGC) in improving the degree of recanalization in conjunction with mechanical thrombectomy. Methods: The medical records of a prospectively collected endovascular ischemic stroke database were reviewed...

Percutaneous coronary intervention (PCI) for anomalous right coronary artery (RCA), originating from the left coronary cusp is challenging, because of the difficulty in engaging the guiding catheter coaxially, and delivering balloons and stents. A 65-year-old man with effort angina underwent PCI for anomalous RCA. This report describes the method we used. Although, delivering the balloon was difficult in short of the guiding catheter's backup force, we finally succeeded by using one more guiding catheter and the balloon-anchored CoKatte ® , a novel, straight 4...

BACKGROUND: Cerebral venous sinus thrombosis (CVST) is a relatively uncommon cause of stroke in pediatric and young adult. The clinical course of CVST is also highly variable. In particular, coma has been noted as a predictor of poor outcome. The standard treatment for CVST in adults is systemic anticoagulation, which can lead to recanalization. Endovascular mechanical thrombectomy (EMT) is considered as possibly indicated in the event of failure to respond to anticoagulation or a comatose state...

BACKGROUND: Isolation of endothelial colony-forming cells (ECFCs) is difficult due to the extremely low concentration of their precursors in the peripheral blood (PB). We hypothesized that mechanical injury to the arterial wall during percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) may increase the release of circulating ECFC precursors and induce their growth in vitro. METHODS: PB samples from patients with coronary artery disease were collected before, immediately after, and 24 h after the surgery in the CABG group...

Technical advances with devices such as catheters, balloons, and stents have widened the indications for endovascular coiling for unfavorable aneurysms. The authors report two cases of coil embolization for a wide-neck bifurcated aneurysm with anterograde horizontal stenting via microcatheter looping. Two women, aged 56 and 38 years, respectively, had an undertall- and overwide-neck aneurysm with bifurcated branches at the basilar bifurcation and middle cerebral bifurcation, respectively. The delivery microcatheter was steamed so that it could be looped deliberately to the opposite vessel...

BACKGROUND: Respiratory mechanics affects the effect of positive end-expiratory pressure (PEEP) on intracranial pressure (ICP). Respiratory mechanics of the lung and the chest wall was not differentiated in previous studies. In the present study, we investigated the influence of the following possible determinants of ICP responsiveness to PEEP: chest wall elastance (ECW ), lung elastance (EL ), and baseline ICP. METHODS: Eight healthy Bama miniature pigs were studied...

OBJECTIVE: The goal of this work was to demonstrate technical feasibility of automated balloon pressure management during REBOA in the pre-clinical setting. METHODS: This paper presents an intelligent balloon management device which automates the balloon inflation process, preventing the possibility of balloon over or under inflation, optimizes inflation pressure and if indicated, deflates automating partial REBOA to allow distal organ perfusion. Edwards TruWave pressure transducers are used to monitor the blood pressure proximal and distal to the balloon, as well as the internal balloon pressure...

Introduction: The mechanical circulation support used in treatment of low cardiac output at most is the intra-aortic balloon pump (IABP). Its usage fields are the complications occurring due to ischemic heart disease, disrupted left ventricle function, and the low cardiac output syndrome occurring during coronary artery by-pass surgery. Methods: During 28 years from 1985 to 2013, IABP support has been implemented to 3135 patients in our cardiac surgery operating theater and intensive care unit. The mean age of the patients was 61...

We report a case of successful percutaneous retrieval of an unexpectedly disrupted balloon catheter using GuideLiner and a low-profile balloon. The procedure and the mechanism of this novel technique were described in detail with ex-vivo testing. This case demonstrated the utility of the combination of GuideLiner and low-profile balloon as a bail-out for intravascular foreign body.

BACKGROUND: Balloon aortic valvuloplasty (BAV) is routinely performed preceding transcatheter aortic valve implantation (TAVI). Among risks inherent in BAV is low cardiac output due to rapid ventricular pacing (RVP), especially in patients with severely impaired left ventricular function. We herein report early experience utilizing a non-occlusive balloon for BAV (TrueFlow™, BARD, Peripheral Vascular, Tempe, AZ, US), which does not require RVP. METHODS: Between 11/2016 and 10/2017, 27 consecutive patients received TAVI using a non-occlusive balloon valvuloplasty catheter for predilatation and a self-expandable transcatheter heart valve (77...

A 46-year-old man underwent angioplasty of a restenotic bifurcation lesion of the circumflex artery. The procedure required repeated balloon exchanges and during the last balloon inflation, no balloon was visualized. A test injection revealed a massive coronary air embolism due to expulsion of air that had accumulated in the guiding catheter shaft. The patient was rapidly resuscitated from electromechanical dissociation with intracoronary injection of adrenaline and atropine and forceful intracoronary saline injections...

Congenital nasolacrimal duct obstruction (CNLDO) is a common condition causing excessive tearing or mucoid discharge from the eyes, due to blockage of the nasolacrimal duct system. Nasolacrimal duct obstruction affects as many as 20% children aged <1 year worldwide and is often resolved without surgery. Available treatment options are conservative therapy, including observation, lacrimal sac massage and antibiotics, and invasive therapy. Observation, combined with conservative options, seems to be the best option in infants aged <1 year...

Mapping of scar-related ventricular tachycardia (VT) in structural heart disease is fundamentally driven by identifying the critical isthmus of conduction that supports re-entry in and around myocardial scar. Mapping can be performed using activation and entrainment techniques during VT, or by substrate mapping performed in stable sinus or paced rhythm. Activation and entrainment mapping requires the patient to be in continuous VT, which may not be haemodynamically tolerated, or, if tolerated, may lead to adverse sequelae related to impaired end organ perfusion...

Background and Purpose- Endovascular treatment for acute intracranial atherosclerosis-related large vessel occlusion (ICAS [+]-LVO) is one of the challenging issues in modern mechanical thrombectomy era. We evaluated procedural and clinical outcomes of endovascular treatment for the ICAS (+)-LVO. We also compared their outcomes with those of large vessel occlusion not associated with intracranial atherosclerosis (ICAS [-]-LVO). Methods- We retrospectively reviewed consecutive patients with acute stroke who underwent endovascular treatment for LVO...

BACKGROUND: Balloon dilatation or debulking seems to be essential to allow successful stent implantation in calcified coronary lesions. Compared with standard balloon predilatation, debulking using high-speed rotational atherectomy (RA) is associated with higher initial procedural success albeit with higher in-stent late lumen loss at intermediate-term follow-up. Whether modified (scoring or cutting) balloons (MB) could achieve similar procedural success compared with RA is not known...
