    Abstract Objective: The Atrial Flow Regulator (AFR) is a double disc device made of self-expanding Nitinol wire mesh, structured around a central lumen. Once deployed via the transfemoral route, the device stents the atrial septum leaving a preselected fixed diameter atrial communication. We sought to evaluate the mid-term performance of the AFR by implanting the device in 5 healthy porcine hearts to assess safety and patency of the device fenestration over a period of 150 days. Method: Five AFR devices were implanted in 5 female Yucatan adult minipigs. The animals were survived to 150 days with periodic… More > Graphic Abstract

    Abstract The percutaneous closure of ostium secundum atrial septal defects (ASD) is a well-established procedure. Currently available devices and delivery systems are designed to be used via the femoral venous route. However, an alternative approach needs to be considered in cases of congenital or acquired caval obstruction. We describe a successful transjugular closure of a moderate sized secundum ASD with the Cocoon Septal Occluder in a 37-year-old symptomatic woman with inferior vena cava (IVC) thrombosis, using a novel deployment technique to overcome difficulties, namely maintaining stable sheath position in the left atrium. Percutaneous closure of secundum More >
