OBJECTIVES This study sought to evaluate feasibility of nonsurgical transthoracic catheter-based left ventricular (LV) access and closure. BACKGROUND Implanting large devices, such as mitral or aortic valve prostheses, into the heart requires surgical exposure and repair. Reliable percutaneous direct transthoracic LV access and closure would allow new nonsurgical therapeutic procedures. MET...
BACKGROUND In patients with percutaneous device implantation for closure of patent foramen ovale (PFO), a 10% incidence of new or worsened aortic regurgitation within 12 months has been reported with echocardiography. Cardiac magnetic resonance imaging is a powerful noninvasive tool to quantify volume and fraction of valve insufficiencies. We studied the acute and long-term impact of percutaneo...
OBJECTIVES To determine the causes and outcome of residual shunting after transcatheter occlusion of persistent ductus arteriosus with the Rashkind double umbrella occluder, and to determine the potential of the device to produce obstruction to flow in the aorta and left pulmonary artery. DESIGN Angiographic examination of morphology of ductus followed by prospective clinical and ultrasound e...
AIMS Percutaneous patent foramen ovale (PFO) closure for secondary stroke prevention is discussed controversially. Long-term data comparing different closure devices are limited. The objective is the prospective comparison of procedural complications and long-term results after PFO closure in patients with cryptogenic stroke randomized to three different closure devices. METHODS AND RESULTS B...
OBJECTIVE Large flap valve patent foramens may cause paradoxical thromboembolism and neurological decompression illness in divers. The ability of a self expanding Nitinol wire mesh device (Amplatzer septal occluder) to produce complete closure of the patent foramen ovale was assessed. PATIENTS Seven adults, aged 18-60 years, who had experienced neurological decompression illness related to di...
A large fistula from the left coronary artery to the right ventricle was successfully closed percutaneously in a 40 year-old patient using a patent ductus arteriosus occluder. The device was positioned and deployed via the venous system using a guidewire that had been advanced via the aorta, coronary artery and fistula to the venous circulation (arterio-venous loop creation). No complications w...
