Официальное название
A Prospective, Multicenter, Randomized Controlled Clinical Study on the Safety and Effectiveness of the SnowyTM PFO Closure System in Plugging Patent Foramen Ovale
Обзор
To evaluate the safety and effectiveness of the SnowyTM PFO closure system in plugging patent foramen ovale
Подробное описание
A prospective, multicenter, randomized controlled clinical trial is conducted to evaluate the safety and effectiveness of PFO closure system produced by Hangzhou Dinova EP Technology Co., Ltd.., Ltd. in closing patent foramen ovale (PFO). 242 patients are expected to be selected. They are randomly divided into the PFO closure system treatment group (121 cases) and the Chinese medicine Shengjie Cardi-o-fix PFO occluder treatment group (121 cases) according to 1:1. All patients will be followed up to 7 days after operation or before discharge, 1 month, 3 month, 6 month, 1 year, 2 year, 3 year, 4 year and 5 year.
