Suboptimal iliofemoral artery access requiring alternative trans-catheter aortic valve replacement (TAVR) access is still encountered in 10-20% of subjects undergoing TAVR. Attempting suboptimal vascular access may result in excessive vessel injury, bleeding and even death. Reported is an innovative procedure to address suboptimal heavily calcified iliofemoral access by using Diamondback 360 peripheral orbital atherectomy (POA) to ablate heavy endoluminal vascular calcifications followed by balloon angioplasty...

We reported the role of endobronchial ultrasound as complement to standard diagnostic exams to better define the benign tracheal stenosis (i.e., thickness and tracheal cartilage integrity) and to plan the treatment with flexible instead of rigid bronchoscope. Under sedation and spontaneous ventilation, the flexible bronchoscope was inserted through the laryngeal mask airway that assured the ventilation. The stenosis was first resected with cold scissors and then dilated with balloon catheter. This strategy was successfully applied in five consecutive patients...

BACKGROUND: Chronic thromboembolic pulmonary hypertension (CTEPH) is a progressive disorder with a poor prognosis. Recently, balloon pulmonary angioplasty (BPA) has been reported to be an effective treatment for inoperable patients with CTEPH. However, this catheter-based treatment has potentially life-threatening vascular complications. To improve the efficacy and safety of BPA, we assessed the morphological evaluation of organised thrombus and the vascular injury by BPA procedure. METHODS: In this study, we assessed the morphology of organised thrombi and the vascular injury observed by angioscopy during BPA in 28 lesions from nine CTEPH patients...

BACKGROUND AND AIMS: A simple, safe, targeted, and efficient in vivo DNA delivery system is necessary for clinical-grade liver-targeted gene therapy in humans. Intravascular hydrodynamic gene delivery has been investigated in large animal models, but translation to humans has been hampered by its technical challenges, invasiveness, and potential for significant cardiovascular adverse events. We posited that intrabiliary delivery of DNA plasmids via ERCP-guided hydrodynamic injection could overcome these obstacles...

Hemorrhage remains the leading cause of preventable deaths in trauma. Endovascular management of non-compressible torso hemorrhage has been at the forefront of trauma care in recent years. Since complete aortic occlusion presents serious concerns, the concept of partial aortic occlusion has gained a growing attention. Here, we present a large animal model of hemorrhagic shock to investigate the effects of a novel partial aortic balloon occlusion catheter and compare it with a catheter that works on the principles of complete aortic occlusion...

We describe a 52-year-old male who underwent endoscopic retrograde biliary drainage for acute cholangitis associated with common bile duct stones. Endoscopic papillary balloon dilatation was performed, and the stones were removed using a balloon catheter. Simultaneously, we initiated edoxaban for portal vein thrombosis. Approximately one month later, he visited our hospital complaining of tarry stools and dizziness. Contrast-enhanced computed tomography revealed a pseudoaneurysm in the hepatic artery (A7), and he was diagnosed with hemobilia from bile duct perforation associated with the hepatic arterial pseudoaneurysm...

Coronary artery perforation (CAP) during percutaneous coronary intervention is a rare but serious complication. Treatment options of CAP include prolonged balloon inflation, covered stent, and coil embolization. Although most cases of CAP can be treated with prolonged balloon inflation, some cases, especially Ellis grade III CAP require covered stents or coiling. Covered stents may require a large bore guide catheter and have a high rate of restenosis, which can be a limiting factor in patients with severe peripheral arterial disease...

BACKGROUND: Incomplete stent expansion and inadequate apposition predispose to stent thrombosis following percutaneous coronary intervention. Recent studies have shown that increasing the duration of balloon inflation during stent employment was beneficial. Thus, the balloon inflation time required for optimal stent expansion and apposition in patients receiving second-generation drug-eluting stents (DES) were determined using optical coherence tomography (OCT). PATIENTS AND METHODS: Between April 2014 and March 2015, 38 patients (28 men, 10 women; mean age 60...

Spontaneous pneumothorax is a rare complication of pneumocystis jirovecii pneumonia. We report a patient with pneumocystis jirovecii pneumonia and therapy-refractory, right-sided pneumothorax due to persistent air leak (PAL) despite prolonged chest tube placement and multiple pleurodesis attempts. Due to the patient's morbidity, we evaluated if the PAL can be sealed by unidirectional endobronchial valves (EBVs). After occlusion of the right upper lobe by a balloon catheter, the air leak flow-rate decreased from 800 ml/min to 250 ml/min...

BACKGROUND: Despite high recanalization rates achieved with endovascular treatment of acute ischemic strokes, around 50% of eligible patients will not achieve a good outcome. Parameters that may determine patient outcomes include: time from puncture to recanalization, the collateral status, the anesthesia regimen, blood pressure management, and distal emboli. Characterization of distal emboli generated during mechanical thrombectomy has been performed in previous studies. OBJECTIVE: To further investigate the risk of distal embolization associated with microcatheter navigation across the clot...

INTRODUCTION: Evidence has shown that balloon catheters are as effective as prostaglandins (PGE) in achieving vaginal delivery within 24 hours of the start of induction of labour (IOL), with lower rates of uterine hyperstimulation, and similar Caesarean section and infection rates. International guidelines recommend mechanical methods as a method of IOL. We designed a prospective randomised controlled study to evaluate patient acceptance of the cervical ripening balloon (CRB) for IOL...
