We describe a novel technical approach to acute stroke illustrated by the case of a 41 year old male who presented with tandem right common carotid artery (CCA) and M1 occlusions. His NIHSS was 17 and Alberta stroke programe early CT score (ASPECTs) was 8. Thrombectomy initially proved challenging due to large volume CCA thrombus that repeatedly occluded the aspiration catheters. However, by inflating a balloon distally and pulling clot into the adjacent ECA, we were able to quickly restore distal contrast flow to the intracranial circulation and achieve Thrombolysis In Cerebral Infarction/Arterial Occlusive Lesion (TICI2C/AOL3) revascularization...

AIMS: To address the limitations of the two-balloon system for kissing balloon inflation (KBI) for the treatment of coronary bifurcation lesions (CBL), we report a novel coronary dedicated bifurcated balloon (DBB) catheter system. METHODS AND RESULTS: The device has been developed to follow the bifurcation geometry according to scaling laws of coronary anatomy. In an in vivo study, the DBB catheter was compared to the KBI technique in post-stent deployment of a bifurcation of a normal swine...

OBJECTIVES: The goal of this study is to evaluate the safety and efficacy of the second-generation robotic-assisted system CorPath GRX (Corindus) for percutaneous coronary intervention (PCI). BACKGROUND: The first-generation CorPath 200 robotic-assisted system for PCI is effective, but is limited by the lack of an active robotic guide-catheter control. The CorPath GRX device enables robotic guide-catheter manipulation, in addition to guidewire and balloon/stent delivery...

Anthony Andreas Theodorides
Elastomeric pumps are mechanical devices composed of an elastomeric balloon reservoir into which the drug to be infused is stored, a protective casing (used by some manufacturers), a flow controller and a wound catheter. In orthopaedics they are used to provide continuous local infiltration analgesia. In this way patients rely less on other routes of analgesia and thus avoid their systemic side effects. Studies have shown good response to analgesia with these pumps for the first 24 hours but their benefit is not as clear at 48 and 72 hours...

Balloon dilation of the Eustachian tube has been recently introduced as a novel and minimally invasive method for treating chronic obstructive Eustachian tube dysfunction. For the first time worldwide, we assessed the role of this technique in the treatment of children with Eustachian tube dysfunction who did not respond to other treatments. We retrospectively analysed the medical records of 60 children (mean age: 6.3 years, range: 28 months to 12 years) who underwent balloon dilation of the Eustachian tube using the Bielefeld balloon catheter...

BACKGROUND: Randomized controlled trials have reported favorable 1-year outcomes with drug-coated balloons (DCBs) for the treatment of symptomatic peripheral arterial disease when compared with standard percutaneous transluminal angioplasty (PTA). Evidence remains limited on the durability of the treatment effect with DCBs in the longer term. METHODS AND RESULTS: IN.PACT SFA is a single-blind, randomized trial (Randomized Trial of IN.PACT Admiral Paclitaxel-Coated Percutaneous Transluminal Angioplasty [PTA] Balloon Catheter vs Standard PTA for the Treatment of Atherosclerotic Lesions in the Superficial Femoral Artery [SFA] and/or Proximal Popliteal Artery [PPA]) that enrolled 331 patients with symptomatic (Rutherford 2-4) femoropopliteal lesions up to 18 cm in length...

Catheter ablation for symptomatic and drug-resistant atrial fibrillation is considered as the main acquired cause of pulmonary vein stenosis in adults. Controversy currently exists about the optimal treatment approach of this entity. Stenting seems to achieve lower vessel restenosis rates than isolated balloon angioplasty. However, these techniques are not exempt from complications. We present a case of spontaneous massive haemothorax presenting as a late complication of stent implantation in a patient with pulmonary vein stenosis...

Since 1998 pulmonary hypertension has been clinically classified into five well-defined, distinct categories. A definitive diagnosis of pulmonary hypertension requires the invasive confirmation of an elevated mean pulmonary artery pressure of 25 mm Hg or above during a right heart catheterization. From a hemodynamic point of view, pulmonary hypertension is classified into precapillary and postcapillary pulmonary hypertension on the basis of a pulmonary artery wedge pressure threshold value of 15 mm Hg. Pulmonary vascular resistance is better characterized by multi-point pressure/flow measurements than by single-point determination...

Robotic percutaneous coronary interventions have recently been introduced in the cardiac catheterization laboratory. Robotics offers benefits of greater precision for stent placement and occupational hazard protection for operators and staff. First generation systems were able to advance and retract coronary wires, balloons, and stents, but did not have guide control functions. The second-generation robotic system (CorPath GRX) has an active guide management function offering the ability to move guide catheters...

The Eustachian tube protects against secretion, germs and sound pressure from the nasopharynx, it acts as a drain, and serves pressure equalization in both directions so that the ear drum and sound-conducting apparatus can vibrate optimally. The incidence of Eustachian tube dysfunction in adults is about 1%, in children almost 40%. Symptoms are often unspecific. For diagnosis, the Eustachian tube score (ETS-5) can be used in patients with a perforated ear drum, and the ETS-7 score in patients with intact ear drum...

AIM: The balloon assisted tracking (BAT) technique is utilised to overcome various anatomical difficulties during radial procedures when standard measures such as adequate sedation, pain relief, vasodilators and use of hydrophilic guidewires, fail. The aim of this study was to evaluate the success rates of the BAT technique in overcoming anatomical difficulties during radial coronary interventional procedures. METHODS: We retrospectively reviewed 1100 consecutive patients undergoing coronary procedures from the transradial approach (TRA) between May 2015 and May 2017...

For patients with prior coronary artery bypass graft surgery, reaching lesions in native coronary arteries distal to the anastomosis of bypass grafts can be challenging due to long distance between the graft ostium and the lesion and significant tortuosity that needs to be traversed. We describe one such lesion in a patient presenting with non-ST segment elevation myocardial infarction and cardiogenic shock. The lesion was successfully treated using a variety of strategies, including use of a short guide catheter, long guidewire, a guide catheter extension, long shaft balloons and stents, and short length stents...

BACKGROUND: Since Misoprostol Vaginal Insert (MVI - Misodel ®) was approved for labor induction in Europe in 2013, to date, no study has been published comparing MVI to Misoprostol vaginal tablets (MVT). The aim of this study, performed as part of a quality improvement project, was to compare the efficacy and safety of 200 μg MVI versus 25 μg MVT for labor induction in nulliparous women. METHODS: This retrospective cohort study included 171 nulliparous singleton term deliveries induced with MVI (n = 85) versus MVT (n = 86) at Oslo University Hospital Rikshospitalet, Norway, from November 2014 to December 2015...

BACKGROUND: Mild therapeutic hypothermia (32-36 °C) is associated with improved outcomes in patients with brain injury after cardiac arrest (CA). Various devices are available to induce and maintain hypothermia, but few studies have compared the performance of these devices. We performed a prospective study to compare four frequently used cooling systems in inducing and maintaining hypothermia followed by controlled rewarming. METHODS: We performed a prospective multi-centered study in ten ICU's in three hospitals within the UPMC health system...

CHD affects millions of patients worldwide. Interventional therapies for CHD goes back to the mid-1960s when Bill Rashkind performed balloon atrial septostomy on a cyanotic baby with transposition of the great vessels. This was followed by development of balloon catheters to perform balloon valvuloplasties and angioplasties in the early to late 1980s. Although King and Mills performed the first transcatheter closure of secundum atrial septal defect in the mid-1970s, this procedure was better realised in the mid-1990s...

Axillary access for an intra-aortic balloon pump allows patients with advanced heart failure (HF) to sit upright and ambulate while waiting for destination therapy or bridging to heart transplantation. We describe the combination of radial access for positioning a 4F pigtail catheter to allow axillary angiography and provide a target for a micropuncture needle entry point in a fully anticoagulated patient with advanced HF.
