598: A Stroke of Luck: A Hypercoagulable State Saved by an Atrial Septal Defect

Cryptogenic stroke after percutaneous closure of an atrial septal defect.

We present the case of a patient who underwent a percutaneous secundum atrial septal defect (ASD II) closure with an undersized septal occluder device. One week and one month later she experienced two transient ischemic attacks. Three-dimensional transesophageal echocardiography (TEE) revealed a residual patent foramen ovale (PFO) with a positive Valsalva bubble test. She underwent a second pro...

Atrial Septal Defect – A Review

Defects in the atrial septum cause left to right shunt because the left atrial pressure is higher than that in the right atrium. This causes volume overloading of the right ventricle. While this is generally well tolerated in infancy and childhood, development of exercise intolerance and arrhythmias in later childhood and adolescence, and the risk for development of pulmonary vascular obstructi...

Integrated Percutaneous Atrial Septal Defect Occlusion and Pulmonary Balloon Valvuloplasty

Introduction: Atrial Septal Defect (ASD) is one of the most common congenital heart diseases during childhood. Today, ASD closure is done by occlutech device via cardiac catheterization. ASD repair with transcatheter technique has shown high closure rate. However, coexistence of severe pulmonary stenosis and large defect in atrial septum is rare. When these two problems coexist, the result is i...

Simultaneous Closure of a Left Atrial Appendage through an Atrial Septal Defect and the Atrial Septal Defect

Left atrial appendage (LAA) occlusion can be employed as an alternative treatment to oral anticoagulation in patients with atrial fibrillation to prevent embolic events. Atrial septal defect (ASD) may be related with right heart dysfunction and allow paradoxical embolism to occur. However, occlusion of both LAA through atrial access with ostium secundum ASD and ASD in the same setting is unusua...
