The temporary total artificial heart (TAH-t) has been valuable as a bridge to transplantation in patients with biventricular failure. However, the challenges of accurately assessing pulmonary vascular resistance after TAH-t implantation can preclude these patients from heart transplantation, especially those with pre-existing pulmonary hypertension. The CardioMEMS Heart Failure System (St. Jude's Medical, Little Canada, MN) comprises a wireless pressure sensor that is implanted percutaneously in the pulmonary artery and transmits real-time measurements of pulmonary artery pressures...

PURPOSE: Establishment of an end-to-end system for the brachytherapy (BT) dosimetric chain could be valuable in clinical quality assurance. Here, the development of such a system using MOSFET (metal oxide semiconductor field effect transistor) detectors and experience gained during 2 years of use are reported with focus on the performance of the MOSFET detectors. METHODS AND MATERIALS: A bolus phantom was constructed with two implants, mimicking prostate and head & neck treatments, using steel needles and plastic catheters to guide the (192)Ir source and house the MOSFET detectors...

Aims: Catheter ablation is underutilized in atrial septal defect (ASD) patients who have undergone implantation of an atrial septal occluder (ASO). This study evaluates the feasibility and safety of catheter ablation of atrial fibrillation (AF) in this subset of patients. Methods and results: Sixteen patients (age 56 ± 12 years, 10 men) with drug-refractory AF (10 paroxysmal and 6 persistent) and previously implanted ASO were enrolled. Balloon dilatation of the closure device was performed if the native septum passage could not be achieved...

INTRODUCTION: Repair of long ureteral defects often requires long graft tissues and extensive surgery. This is associated with complications including a lack of suitable tissue and graft site morbidity. Tissue engineering may provide an attractive alternative to the autologous graft tissues. In this study, ureteral repair using (pre-implanted) tubular collagen-Vicryl templates was evaluated in a new goat model. MATERIALS AND METHODS: Tubular templates were prepared from tubularized Vicryl meshes and 0...

PURPOSE: Implantable loop recorders (ILRs) are increasingly being used for ambulatory electrocardiography. We sought to evaluate ILR indications, diagnostic yield, ILR-guided interventions, and complications in two Canadian centers. METHODS: This was a retrospective study using electronic medical records to identify ILR implants at Queen's University and the University of Manitoba. Information was collected on patient characteristics, medications, indication for implant, results of prior investigations, diagnostic outcome, and subsequent management...

Aims: Pulmonary vein stenosis or occlusion (PVS/O) following catheter ablation of atrial fibrillation is a rare but potentially severe complication. Treatment options include angioplasty with or without stent implantation, but data on outcome and optimal treatment strategy are limited. We report long-term results after catheter-based treatment of patients with symptomatic PVS/O. Methods and results: Retrospective analysis was performed in patients undergoing pulmonary vein (PV) angiography for suspected PVS/O...

BACKGROUND: Antiarrhythmic treatment of patients with recurrent ventricular tachyarrhythmia, in whom catheter ablation and amiodarone treatment were ineffective or contraindicated, is an unsolved clinical problem. AIM: The study aims to evaluate the efficacy and tolerability of mexiletine in patients with recurrent ventricular tachyarrhythmias and/or electrical storm events, in whom standard treatment strategies failed to prevent ventricular tachyarrhythmia. METHODS: We performed a retrospective cohort analysis of all patients treated with mexiletine for recurrent ventricular tachycardia and/or ventricular fibrillation in our institution between January 2011 and September 2015...

BACKGROUND: Biventricular failure is associated with high in-hospital mortality. Limited data regarding the efficacy of biventricular Impella axial flow catheters (BiPella) support for biventricular failure exist. The aim of this study was to explore the clinical utility of percutaneously delivered BiPella as a novel acute mechanical support strategy for patients with cardiogenic shock complicated by biventricular failure. METHODS AND RESULTS: We retrospectively analyzed data from 20 patients receiving BiPella for biventricular failure from 5 tertiary-care hospitals in the United States...

PURPOSE: Pulmonary embolism (PE) is a frequently occurring complication in critically ill patients. Simultaneous occurrence of PE and life-threatening bleeding, may render medical anticoagulation impossible. For these patients, inferior vena cava filters (IVCF) present a valuable therapeutic alternative. The Angel® catheter is a novel IVCF that provides temporary protection from PE and is implanted at bedside. The primary objective of the European Angel® catheter registry is to evaluate the safety and efficacy of this IVCF...

BACKGROUND: Total hip arthroplasty is one of the most common procedures in orthopaedic surgery. We hypothesized that local infiltration of analgesia and continuous wound infusion of anaesthetics in the first 72 h after surgery could provide more effective postoperative analgesia with better rehabilitation. METHODS: A double-blind, randomized, controlled study was conducted with 96 patients who underwent total hip arthroplasty. The patients were randomized to receive either a local infiltration analgesia and continuous wound infusion of anaesthetics or a local infiltration analgesia and continuous wound infusion of saline solution...

INTRODUCTION: Pulmonary vein isolation (PVI) is an effective therapy for paroxysmal atrial fibrillation (AF), but it has limitations. The two most significant recent advances have centred on the integration of real-time quantitative assessment of catheter contact force into focal radio frequency (RF) ablation catheters and the development of dedicated ablation tools capable of achieving PVI with a single ablation lesion (Arctic Front cryoballoon, Medtronic, Minneapolis, MN, USA). Although each of these holds promise for improving the clinical success of catheter ablation of AF, there has not been a rigorous comparison of these advanced ablation technologies...

Intravascular Ultrasound (IVUS) of coronary arteries has lately been extensively used in the routine work of catheter laboratories. This method`s availability for qualifying the structure of atherosclerosis plague, degree of stricture formation in artery opening, length of the plaque while choosing the relevant size of stent and also for stent apposition control after implantation, makes IVUS an irreplaceable help in endovascular surgeons` work. Combination of coronary angiography and IVUS best represents the plaqued segments of artery total picture...

Totally implanted venous access ports (TIVAPs) are commonly used catheters for the management of acute or chronic pathologies. Although these devices improve health care, repeated use of this type of device for venous access over long periods of time is also associated with risk of colonization and infection by pathogenic bacteria, often originating from skin. However, although the skin microbiota is composed of both pathogenic and nonpathogenic bacteria, the extent and the consequences of TIVAP colonization by nonpathogenic bacteria have rarely been studied...

PURPOSE: The frontline treatment for localized muscle-invasive bladder carcinoma (MIBC) is radical cystectomy. However, a significant percentage of this population is elderly with either severe co-morbidities or suboptimal general health, increasing the per- and post-operative risk when undergoing a radical cystectomy. Conservative treatment options have been implemented such as robot-assisted laparoscopic brachytherapy (RALB), a minimally invasive therapeutic approach ensuring excellent results in terms of local control, survival, and low morbidity...
