BACKGROUND: Perforated duodenal ulcers can be treated with a covered stent. Stent migration is a severe complication, sometimes requiring surgery. Pyloric physiology during stent treatment has not been studied and mechanisms for migration are unknown. The aim of this study was to investigate the pyloric response to distention, mimicking stent treatment, using the EndoFLIP. METHODS: A nonsurvival study in five pigs was carried out, followed by a pilot study in one volunteer...

INTRODUCTION: When transcatheter aortic valve replacement (TAVR) was introduced, pre-implantation balloon aortic valvuloplasty (BAV) was a routine part of the procedure. Smaller device profiles have resulted in selective use of BAV; however, there is a paucity of data about the trend in use of direct TAVR and the safety of this strategy. METHODS: All patients who underwent TAVR at a Veterans Affairs Medical Center from September 2013 to November 2016 were included in this retrospective analysis...

AIMS: Transradial access (TRA) has become a standard approach for cardiac catheterization. However, an obstacle to TRA is the risk of radial artery occlusion (RAO) after radial access in about 5%-10% of patients. We analyzed the safety and efficacy of getting vascular access after RAO by percutaneous transluminal angioplasty in cases of chronic radial occlusion. METHODS AND RESULTS: Chronic RAO was confirmed by Allen test and color Doppler in 8 patients. TRA was achieved by puncture in the distal tabatiere (anatomical snuffbox) using Seldinger's technique followed by insertion of a 5 Fr radial introducer sheath...

Data from previous studies of patients with heart failure and coronary artery disease suggest that those with higher resting heart rates (HRs) have worse cardiovascular outcomes. We sought to evaluate whether HR immediately before percutaneous coronary intervention (PCI) is an independent predictor for 30-day outcome. We analyzed the outcome of 3,720 patients who had HR recorded before PCI from the Melbourne Interventional Group registry. HR and outcomes were analyzed by quintiles, and secondarily by dichotomizing into <70 or ≥70 beats/min...

Pulmonary vein stenosis (PVS) is still a frustrating disease with extremely high mortality, especially in children with multiple severe PVS. Hybrid pulmonary vein stenting (HPVS) is a rescue treatment for recurrent and malignant PVS. The aim of this study is to share our successful experience with intraoperative HPVS for recurrent PVS after total anomalous pulmonary venous connection (TAPVC) repair in infant. Six patients were identified between 2013 and January 2018, who were diagnosed with recurrent PVS and underwent HPVS in the operating room...

Objective: One of the late-onset complications of cardiac implanted electronic devices (CIEDs) is central venous obstruction (CVO). The aim of this study was to investigate the feasibility, efficacy, and safety of endovascular treatment of CIED-related CVOs. Methods: Eighteen patients who underwent endovascular management of their device-related CVO were reviewed. Patients were classified into three groups: Group I patients were asymptomatic and needed lead replacement; Group II patients presented with symptomatic CVO without lead dysfunction, and Group III patients were referred with both symptomatic CVO and lead dysfunction...

Venous bullet embolism is a rare complication of trauma. We describe a patient who sustained a gunshot wound. Computed tomography revealed antegrade embolization of the bullet to the right hepatic vein (RHV). The risk of not retrieving the bullet embolus and subsequent embolization to the pulmonary circulation includes pulmonary artery thrombosis, bleeding, or abscess formation. The bullet was retrieved through right internal jugular vein access; assisted by percutaneous transhepatic repositioning and endovascular balloon-immobilization of the bullet...

Purpose: Drug coated balloons (DCB) are continually improving due to advances in coating techniques and more effective excipients. Paclitaxel, the current drug choice of DCB, is a microtubule-stabilizing chemotherapeutic agent that inhibits smooth muscle cell proliferation. Excipients work to promote coating stability and facilitate paclitaxel transfer and retention at the target lesion, although current excipients lack sustained, long-term paclitaxel retention. Keratose, a naturally derived protein, has exhibited unique properties allowing for tuned release of various therapeutic agents...

Increasing evidence is available for the use of percutaneous coronary intervention (PCI) in selected patients with unprotected left main (LM) bifurcation coronary lesions. However, little data have been reported on recurrent in-stent restenosis (ISR) for LM bifurcation lesions. The aim of this study was to evaluate the efficacy of a drug-eluting balloon (DEB) for LM bifurcation ISR compared with that of a drug-eluting stent (DES).Between December 2011 and December 2015, 104 patients who underwent PCI for unprotected LM bifurcation ISR were enrolled...

BACKGROUND: Vascular complications are an important complication of transcatheter aortic valve implantation (TAVI) and are associated with increased morbidity and mortality as well as cost. The Solopath device is an expandable vascular access system that has previously been shown to be associated with lower rates of vascular complications. We sought to evaluate the impact of the use of this system on vascular complications and costs in a decision model analysis. METHODS: A cost-consequence analysis was undertaken utilizing event rate data from the PARTNER trials and a published retrospective analysis of the Solopath device...

PURPOSE: In the evolution of the minimally invasive treatment of vertebral compression fractures, vertebral body stenting (VBS) was developed to reduce intraoperative and secondary loss of vertebral height. Particularly in combination with the usage of biodegradable cement, the influence of VBS on the rate of intraoperative complications and long-term outcome is unclear. The purpose of this study was to investigate the differences between balloon kyphoplasty (BKP) and VBS regarding their long-term clinical and radiological outcome in combination with calcium phosphate (CaP) application instead of polymethyl methacrylate (PMMA)...

INTRODUCTION: Endoscopic balloon dilation (EBD) is the mainstay of endoscopic therapy for laryngotracheal stenosis (LTS), although there is no evidence that it achieves better results than traditional rigid laryngeal dilators. Rigid bougie dilators are less expensive and easier to use, and confer the advantage of providing tactile information about the stenosis to the surgeon. We analyzed the outcome of endoscopic rigid bougie dilatation of LTS in a large series of children and compared it to the reported results of EBD in the same setting...

A 20-week-old fetus was diagnosed with critical pulmonary valve stenosis. Given the ultrasound findings, the outcome was difficult to predict. The fetal cardiologists discussed the possibility of a pulmonary valvuloplasty (an experimental procedure) with the parents, wherein the fetal right ventricle would be punctured with a long 18G needle, and through it, a wire advanced across the pulmonary valve, allowing for balloon dilation of the valve. The experimental procedure had been performed at a handful of centers...
