Percutaneous closure of patent foramen ovale and atrial septal defect A case report

A 67-year old man with a hemodynamically significant type secundum atrial septal defect (ASD), large patent foramen ovale (PFO) and significant septal aneurism presented with shortness of breath and limited exercise tolerance. There was no evidence of additional structural abnormalities nor significant coronary artery disease. Simultaneous percutaneous closure of both defects was planned. Since the wire could have been passed only through PFO and the second wire not through the ASD, only PFO was closed with 35 mm Amplatz PFO occluder. After 3 months, which served for tissue ingrowth of Amplatz PFO occluder and aneurism stabilization, ASD located in posterior-inferior part of fossa ovalis documented by three-dimensional transesophageal echocardiography (3D-TEE) was easily crossed and successfully closed with a 12 mm Amplatz ASD occluder. Stable position without unwanted interference between the devices was obtained. There was noresidual shunting on color Doppler and no bubble shunting during Valsalva maneuver. Within 6 months after the procedure, symptoms significantly improved and right heart chambers decreased. 3D-TEE revealed both devices in good position with only trivial shunting through PFO occluder documented by color Doppler.
