BACKGROUND: We compared the direct inotropic and lusitropic effects of two inodilators, milrinone and levosimendan in patients after aortic valve replacement for aortic stenosis. METHODS: In this randomised, blinded study, 31 patients with normal LV function, were randomised to either levosimendan (0.1 and 0.2 μg/kg/min, n = 15) or milrinone (0.4 and 0.8 μg/kg/min, n = 16) after aortic valve replacement. The effects on LV performance, LV strain, systolic (SR-S) and early diastolic (SR-E) strain rate were assessed by a pulmonary artery catheter and transoesophageal two-dimensional speckle tracking echocardiography of the LV inferior wall...

Damme H Van, E Boesmans, J O Defraigne
Despite major advances in the contemporary management of peripheral arterial occlusive disease, acute ischemia of the lower limb is still characterized by an important morbidity, limb threat, and mortality, and continues to pose a challenge to the vascular surgeon. Ageing of the population increases the prevalence of acute lower limb ischemia. The two principal etiologies of acute ischemia of the lower limbs are arterial embolism and in situ thrombosis of an atherosclerotic artery or of a bypass graft. Popliteal aneurysm thrombosis and vascular trauma are less common causes of severe limb ischemia...

BACKGROUND: Cardiovascular magnetic resonance (CMR) fluoroscopy allows for simultaneous measurement of cardiac function, flow and chamber pressure during diagnostic heart catheterization. To date, commercial metallic guidewires were considered contraindicated during CMR fluoroscopy due to concerns over radiofrequency (RF)-induced heating. The inability to use metallic guidewires hampers catheter navigation in patients with challenging anatomy. Here we use low specific absorption rate (SAR) imaging from gradient echo spiral acquisitions and a commercial nitinol guidewire for CMR fluoroscopy right heart catheterization in patients...

Objective: To observe the effect of 5 F Tiger Ⅰ catheter shaping technique in complex coronary angiography. Methods: This study was a single-center, single-blind, randomized, parallel controlled trial and subjects were consecutively enrolled if the first coronary angiography could not be completed by 5 F Tiger Ⅰ catheterization at our department from January 2016 to June 2017 ( n= 159). The subjects were divided into 2 groups using a random number table method: 79 patients in the control group, and 6 F Judkins and Amplatz catheters were used to perform coronary angiography through the radial artery; 80 patients in the experimental group, and 5 F Tiger Ⅰ shaping technique were used to perform coronary angiography through the radial artery...

I N Shchanitsyn, M R Sharafutdinov, R A Iakubov, I V Larin
A femoral approach is the main access in stenting of carotid arteries, mainly due to rapid training in how to perform the procedure and a possibility of using large-diameter catheters. However, this approach is not always feasible in atherosclerosis, tortuosity of lower-limb arteries and in certain anatomical peculiarities of the aortic arch. Using a transradial approach is based on the desire to diminish the incidence rate of haemorrhagic complications in the zone of the puncture and to avoid the necessity of a long-term bed rest...

Although the arterial switch operation has become the standard procedure for infants with complete transposition of the great arteries, possible late adverse events after surgery have not been fully elucidated. One such problem may be the postoperative function of the aorta that is radically manipulated. The current study enrolled 12 patients aged 4-9 years who had undergone an arterial switch operation. The ascending and descending aortic pressure waveforms were recorded by a catheter-mounted pressure sensor...

We described an 88-year-old woman presented with large aneurysm on the carotid siphon of the right internal carotid artery (ICA). Digital subtraction angiography showed extravasation from the distal cervical segment of the right ICA due to positioning a guiding catheter for intra-aneurysmal coil embolization. Transoral carotid ultrasonography (TOCU) showed arrested bleeding and a pseudolumen in the distal cervical segment of the right ICA. We originally described that TOCU was useful for evaluating iatrogenic extravasation and extracranial ICA dissection during neurointervention...

BACKGROUND: Percutaneous coronary interventions (PCI) of old calcified saphenous vein grafts (SVGs) is challenging and is associated with a considerably high risk of adverse ischemic events in the short- and long-term as compared to native coronary arteries. We report a case in which a non-dilatable, calcified SVG lesion is successfully treated with rotational atherectomy followed by PCI and stenting with local stent delivery (LSD) technique using the Guidezilla™ guide extension catheter (5-in-6 Fr) in the "child-in-mother" fashion...

Background and importance Pial arteriovenous fistulas (AVFs) of the brain are treacherous lesions that can be challenging to treat because of high risk of hemorrhage. We report on a rare case of a pial AVF with a giant venous varix as a draining vein treated successfully with flow-directed balloon-assisted Onyx embolization. Clinical presentation A 56-year-old female with headaches underwent brain magnetic resonance imaging, which demonstrated a 4 cm aneurysmal malformation in the right temporal lobe. A diagnostic cerebral angiogram demonstrated a right temporal pial AVF fed by an enlarged right posterior cerebral artery with drainage into a giant venous varix...

Background The "gold standard" for pain relief after thoracotomy has been thoracic epidural analgesia (TEA). The studies comparing TEA with paravertebral block (PVB) and recent reviews recommend PVB as a novel, safer method than TEA. Methods A systematic search of the Cochrane and PubMed databases for prospective, randomized trials (RCTs) comparing TEA and PVB for post-thoracotomy analgesia was done. We assessed how TEA and PVB were performed, methods of randomization, assessment of pain relief, and complications...

INTRODUCTION: Hemodynamic parameters measurements were widely conducted using pulmonary artery catheter (PAC) with thermodilution as a reference standard. Due to its technical difficulties in children, transthoracic echocardiography (TTE) has been widely employed instead. Nonetheless, TTE requires expertise and is time-consuming. Noninvasive cardiac output monitoring such as ultrasonic cardiac output monitor (USCOM) and electrical velocimetry (EV) can be performed rapidly with less expertise requirement...

We report a case of a woman who presented with worsening shortness of breath due to a migrated ventriculoatrial shunt catheter into the pulmonary artery causing severe pulmonary insufficiency. She underwent surgical catheter removal. The majority of the catheter was easily retrieved; however, there were areas where the catheter was embedded into the myocardium, which would have posed a challenge with an endovascular approach.

Background: Failure of delivering a stent or a balloon across the target lesion during percutaneous coronary intervention (PCI) of chronic total occlusion (CTO), especially in arteries with calcified tortuous anatomy, is often due to insufficient backup support from the guiding catheter. The purpose of this study was to assess the feasibility of the GuideLiner (GL) catheter use. Methods: We examined 18 patients and used the GL catheter to overcome poor support and excessive friction in standardized antegrade and retrograde CTO procedures...

A new Low-profile Visualized Intraluminal Support device (LVIS Blue) is a braided stent that provides a higher degree of metal coverage. This stent may be beneficial for complete obliteration of an aneurysm due not only to its support of a higher occlusion rate using coils inside of the aneurysm but also to its flow diverting effect. We introduce and describe a new flow diversion technique using an LVIS Blue-within-an-Enterprise for patients with vertebral artery (VA) dissecting aneurysms. A 6-Fr guiding catheter was positioned in the ipsilateral VA...

Treatment of blood blister-like aneurysm (BBA) is a challenge due to its unfavourable morphology, small size and the friable neck of BBA. In the management of ruptured BBA, coil placement can be achieved by stent-assisted coil embolisation. We propose to incorporate a new technique using a steam-shaped microcatheter to improve safety. A 59-year-old woman was transferred to our hospital and diagnosed with subarachnoid haemorrhage (SAH) due to a ruptured BBA of the left internal carotid artery (ICA) at the C2 portion...

OBJECTIVE Intraoperative angiography can be a valuable tool in the surgical management of vascular disorders in the CNS. This is typically accomplished via femoral artery puncture; however, this can be technically difficult in patients in the prone position. The authors describe the feasibility of intraoperative angiography via the popliteal artery in the prone patient. METHODS Three patients underwent intraoperative spinal angiography in the prone position via vascular access through the popliteal artery. Standard angiography techniques were used, along with ultrasound and a micropuncture needle for initial vascular access...
