Filter by:This is a prospective, non-randomized, multi-center, real-world post-market study to collect and evaluate data regarding the performance of the enhanced atrial fibrillation detection algorithm of the Assert-IQTM Implantable Cardiac Monitor (ICM) device.
The EMBOL-AF is a multicenter, international, observational study designed as a retrospective registry that will investigate the characteristics of systemic arterial embolic events after treatment of atrial fibrillation by catheter ablation. Due to the retrospective nature of the study, the registry is specially focused on cerebral embolism (stroke and TIA) because these are not only the most frequent and clinically relevant but also the most susceptible to underreporting. However, all embolism associated to AFAbl will be included. This study will gather all clinically relevant aspects and data of all cases of arterial embolism that have occurred over the last 5 years in the centers that will participate in the registry. Based on these reported cases, the incidence, management and outcomes of embolic events (particularly stroke and TIA) will be studied.
This study is set up as a phase I prospective, single center, device interventional pilot study carried in office setting under local anesthesia. It will assess the tolerance and safety of target fusion ablation of prostate cancer tumors using Laser Induced Thermal Therapy (TFA-LITT) guided by fusion imaging in men 50 to 80 years of age with low to intermediate risk prostate cancer Prostate Cancer is currently managed with in a discrete fashion where patients either enroll in active surveillance protocols (No intervention) or undergo full intervention via whole gland treatments - most commonly radical surgery or radiation. These treatments have not shown definitive gains in all cause survival and not uncommonly harbor undesirable adverse effects, most notably: impotency and incontinence. Such events elicit significant and noticeable changes on a male lifestyle and for most prostate cancer tumors are considered overtreatment. This study aims to evaluate the use of TFA-LITT in the office setting under local anesthesia - greatly decreasing patient perioperative surgical risk - focused on the organ sparing cancer lesion ablation, where organ function is preserved. The fundamental objective is to determine the tolerance and safety of TFA-LITT in men with low to intermediate risk prostate cancer, successful performed in the outpatient office-based setting under local anesthesia directed by fusion imaging. Secondary objectives include: 1-Biopsy proven cancer control of ablated areas 12 months after procedure; 2-Uroflowmetry and urinary function Patient Reported Outcome Measures (PROMs) at one, three, six, nine and 12 months; 3- Sexual function Patient Reported Outcome Measures (PROMs) at one, three, six, nine and 12 months; 4- MRI changes of ablated area one, three and 12 months after TFA-LITT; 5- Absence or presence of ejaculation after TFA-LITT.
Developing a deep learning model based on contrast-enhanced ultrasound (CEUS) to predict the prognosis of hepatocellular carcinoma (HCC) and aid choose operation decisions
This randomized, positive control, multicentre trial is designed to compare the analgesic efficacy and safety of nalbuphine hydrochloride injection and morphine hydrochloride injection for perioperative tumor ablation.
Ultrasound (US) as first-line imaging technology in detecting focal liver lesions,also plays a crucial role in evaluating image and guiding ablation which is the main treatment for liver lesions. However, the effect of US in diagnosing liver lesions is challenged by several factors including being highly dependent on doctor's experience, low signal-to-noise ratio, low resolution for lesion feature,large error from thermal field evaluation during the process of ablation and so on. Therefore, it is of great significance to construct an intelligent US analysis system depending on the digital information technology. Basing on these problems,the following research will be involved in our project: 1) US database of liver lesions with seamless connection to Picture Archiving and Communication Systems (PACS) will be developed, with the aim to provide standard data for intelligent US analysis. 2) Deep learning model for accurate segmentation, detection and classification of liver lesions on US images will be studied. Then automatic extraction, selection and analysis of liver lesion ultrasound features and the intelligent US diagnosis for liver lesions will be realized. 3) Proposing a clustering model with deep image features, and depicting the similarity measurement of liver cancer, which can be furthered used to link the liver cancer feature to optimal ablation parameters. The intelligent decision-making system for quantifying thermal ablation will be established. 4) Regression algorithm and Generative Adversarial Nets will be developed to extract the image features of liver cancer which will predict risk factors after US-guided thermal ablation.Based on the above researches, it is of great value to establish an intelligent focal liver lesion US diagnosis system involving intelligent diagnosis,personalized ablation strategy and accurate prognosis evaluation, improving the level of accurate diagnosis and treatment of liver lesions.
The aim of the study is to assess the prevalence of left atrial thrombus in patients with atrial fibrillation (AF) or atrial flutter (AFI), in whom transesophageal echocardiography is performed before AF/AFl cardioversion or ablation.
Premature Ventricular Complex (PVC) ablation is performed in certain indications. Generally acutely abolition of PVC at the time of ablation accepted as successful ablation. However in some patients this effect occurs lately. In this study investigators sought late effect of ablation
Catheter ablation with isolation of the pulmonary veins has proven to be an effective treatment option in patients with paroxysmal atrial fibrillation. In patients who have a relapse of paroxysmal atrial fibrillation after one ablation procedure the investigators compare the reisolation of all pulmonary veins to reisolation plus an anterior left atrial line.
