Using the MB-LATER score for predicting arrhythmia outcome after catheter ablation for atrial fibrillation: The Guangzhou atrial fibrillation project.

Several clinical scoring systems have been derived to predict the arrhythmia outcome of catheter ablation (CA) for atrial fibrillation (AF) but which is better is not clear. Simple clinical risk scores (that any clinician can use in the everyday clinic) can help assess the likelihood of recurrence of AF following CA and the simple MB-LATER score has recently been described. We compare the predictive ability of seven existing clinical scoring systems (HATCH, CHADS , CHA DS -VASc, BASE-AF , APPLE, CAAP-AF, a...


Electroanatomic mapping-guided pediatric catheter ablation with limited/zero fluoroscopy.

The use of fluoroscopy in pediatric catheter ablation has decreased because of mapping systems. In this study, we present the efficiency and reliability of the electroanatomic mapping system in nonfluoroscopic pediatric catheter ablation.

Comparison of the device performance between the conventional guide extension catheter and the soft guide extension catheter.

The guide extension catheter is frequently used in current percutaneous coronary intervention, and the GuideLiner (Vascular Solutions Inc., Minneapolis, MN) has been the standard guide extension catheter. Recently, the Guideplus (Nipro, Osaka, Japan) has emerged as a new guide extension catheter. The aim of the present study was to compare device performance between the Guideplus and GuideLiner.

Dialysis catheter management practices in Australia and New Zealand.

Dialysis catheter associated infections (CAI) are a serious and costly burden on patients and the healthcare system. Many approaches to minimising catheter use and infection prophylaxis are available and the practice patterns in Australia and New Zealand are not known. We aimed to describe dialysis catheter management practices in dialysis units in Australia and New Zealand.

Malfunction of a central venous multilumen access catheter caused by kinking: A case report.

A multilumen access catheter (MAC) is a large-bore catheter that prevents kinking or collapsing. Misplacement is a frequently reported complication.

Reduction of catheter kinks and knots via radial approach.

Coronary angiography and percutaneous coronary intervention using the radial approach are becoming more frequent. Pronounced guide catheter manipulation in cases with tortuous access routes may lead to severe catheter kinking or knotting. The purpose of this review article is to present several techniques to resolve radial access catheter knots and kinks. First, simple maneuvers such as gentle traction, rotation, and guidewire advancement can often resolve minor kinking; however, complex loops and kinks are...

Varan B, Yakut K, Harman A. Transcatheter retrieval of embolized catheter using venovenous loop in a neonate. Turk J Pediatr 2018; 60: 113-115. Umbilical venous catheters are reliable in providing adequate medical care for premature babies however complications include infections, bleeding, thrombosis, catheter occlusion and migration of a piece of catheter to other parts in the body. Here, we present a case with migration of a piece of umbilical venous catheter which has been trapped between hepatic vein a...

Evaluation of later morphologic alterations in renal artery wall and renal nerves in response to catheter-based renal denervation in sheep: comparison of the single-point and multiple-point ablation catheters.

This study evaluated the subacute morphologic alterations in renal artery wall and renal nerves in response to catheter-based renal denervation in sheep and also compared the efficiency of single-point and multiple-point ablation catheters. Effect of each ablation catheter approved for the clinical use (Symplicity Flex(TM), Medtronic, INC. or EnligHTN(TM), St. Jude Medical, INC.) was compared to intact contralateral renal artery in 12 sheep by histopathology and immunohistochemistry evaluation after a 10-da...

The influence of the electrodes spacing of a mapping catheter on the atrial voltage substrate map.

Detailed substrate mapping is important for catheter ablation. However, the influence of the electrode spacing of the mapping catheter on the substrate map has not been well clarified. The aim of this study was to investigate the influence of the electrode spacing of the mapping catheter on the voltage of the substrate map.

Anatomy Revisited: Hemodialysis Catheter Malposition into the Chest.

In most situations, central catheters are implanted in the right jugular vein as initial access for hemodialysis. However, after repeated punctures, the proximal vessels become stenosed and thrombosed and misplacement is likely to occur. Correct catheter position in the vein can be easily ascertained with X-ray or cross-sectional CT imaging. In this report, we describe the case of a 77-year-old patient on chronic hemodialysis via catheter due to arteriovenous fistula dysfunction. We placed a cuffed-tunneled...

Haemodialysis catheter related central venous thrombosis; Clinical approach to evaluation and management.

Central venous catheter use is common among patients undergoing haemodialysis. Catheter related vascular thrombosis is a frequent complication, which results in catheter dysfunction. This may eliminate the affected vein as a potential route of vascular access and leads to significant morbidity of the limbs involved. Despite increasing prevalence, there is a dearth of evidence-based guidelines for managing such catheter related thrombi, often leading to treatment dilemmas in clinical practice. Minimizing the...

Left atrial shape predicts recurrence after atrial fibrillation catheter ablation.

Multiple markers LA remodeling, including LA shape, correlate with outcomes in AF. Catheter ablation is an important treatment of AF, but better tools are needed to determine which patients will benefit. In this study we use particle based modeling to quantitatively assess LA shape, and determine to what degree it predicts AF recurrence after catheter ablation.

Sonographic features of umbilical catheter-related complications.

Umbilical catheters are commonly used in the neonatal period for blood sampling or for administering medication or parenteral nutrition. The position of the catheter is usually confirmed with radiography. However, many complications associated with the use of umbilical catheters, such as liver collections from extravasation or vascular thrombosis, are not apparent on radiographs but can be easily diagnosed with ultrasound. This pictorial review illustrates the sonographic findings of complications that shou...

The Extended Dwell Peripheral Intravenous Catheter Is an Alternative Method of NICU Intravenous Access.

Establishing vascular access is a common neonatal intensive care unit procedure. The extended dwell peripheral intravenous (EPIV) catheter is a 6-cm and 8-cm silicone catheter for peripheral vein insertion, which is a newer vascular access device than peripherally inserted central catheters (PICCs) and peripheral intravenous (PIV) catheter. Extended dwell peripheral intravenous catheters have been widely used in adults but evidence in neonates is lacking.

A dual-mode imaging catheter for intravascular ultrasound application.

Both the morphological anatomy and functional parameters such as flow speed of the artery provide valuable information for the evaluation of cardiovascular diseases. Direct measurement of the arterial wall can be achieved by intravascular optical/ultrasound imaging methods, however no functional data are acquired with these methods. Fractional flow reserve (FFR) and Doppler wire have been used to assess the blood flow information, but do not provide cross-sectional images of the artery. This study is the fi...

Possibilities and limitations of treatment with clear aligners. An orientation.

The aim of this research was to evaluate the efficiency and effectiveness of an orthodontic treatment with clear-aligner systems, specifically with Invisalign®. In addition to a review of the literature, 4 orthodontists and 9 patients treated with fixed orthodontic therapy and Invisalign® were interviewed. The literature showed that it is difficult to correct an extrusion, rotation or overjet with clear aligners. Often 'refinement' (additional intervention during treatment) is necessary to achieve the bes...

First clinical use of novel ablation catheter incorporating local impedance data.

Successful catheter ablation is limited by both poor spatial resolution of abnormal local signals and inability to deliver an effective lesion due to poor tissue contact. We report first worldwide use of the Intellanav MiFi OI catheter (Boston Scientific), providing ultra-high density mapping and incorporating a 'DirectSense' algorithm to measure local tissue impedance (LI).

A novel catheter with retractable stent that can prevent aortic insufficiency during left ventricular assist.

Left ventricle (LV) assist, which refers to the use of a mini-pump or catheter implanted across the aortic valve connected to the pump, can promote myocardial recovery after left ventricle failure. However, conventional LV assist catheters compress the aortic valve, which can induce aortic insufficiency. Here we describe a novel LV assist catheter containing a retractable stent at its distal end that may prevent such insufficiency. The device was tested in six goats in which the coronary artery was ligated ...

Catheter-Related Candida Endocarditis on the Right Atrial Septum - A Case Report.

The use of subcutaneous catheter devices has increased over the past two decades along with its associated infections. One of the complications is infective endocarditis (IE), which usually occurs on the valves of the heart. However, IE can rarely occur on the atrial septal wall. The most common pathogens associated with catheter-related IE are staphylococcus bacteria, and it is rarely caused by fungi. We present a case of a 75-year-old Caucasian female with infective endocarditis located on the right side...

Utility of Preoperative Simulation for Ventricular Catheter Placement via a Parieto-Occipital Approach in Normal-Pressure Hydrocephalus.

Removal of Intrathecal Catheters Used in Drug Delivery Systems.

Implanted intrathecal drug delivery systems (IDDS) are increasingly used in the treatment of spasticity and in patients with refractory pain. Literature discussing complications associated with intrathecal pump placement is widely available. However, reports of complications following the removal of chronically placed catheters are scarce. We reviewed our series of patients who had surgery to remove the intrathecal catheter.

Misplaced Foley catheter in ureter in a female with neurogenic bladder: a rare complication report.

Accidental placement of Foley catheter in ureter is a rare phenomenon. It is more common in females with neurogenic bladder who have hypocontractile bladder or there can be iatrogenic placement during surgical procedures. We describe a case of a female suffering from upper motor neuronal lesion due to trauma at T8 level (American Spinal Injury grade A) following which she developed neurogenic bladder. A Foley catheter was unintentionally placed in the ureter and subsequently removed through a novel techniqu...

Wang's Forceps-Assisted Percutaneous Insertion and Fixation of Peritoneal Dialysis Catheter.

Percutaneous insertion of peritoneal dialysis catheters is theoretically most preferred by nephrologists because of the advantages of bedside performing, surgery independence, and minimal injury over other procedures of catheter placement such as open surgical dissection or laparoscopic operation. However, blindly placing catheters in the percutaneous procedure brings the risk of catheter malposition or bowel perforation; this largely retarded it's implementation. We had previously developed a novel techniq...

Bedside ultrasound diagnosis of a malpositioned central venous catheter: A case report.

Central venous catheter (CVC) placement is commonly performed in intensive care unit. And CVC placement is associated with risks including CVC malposition, pneumothorax. Many of the previously reported cases are about catheter misplacement detected by bedside ultrasound, chest x-ray (CXR) and computed tomography. In this case, malposition was detected by bedside ultrasound incidentally particularly with no clinical manifestation.
