Comprehensive evaluation of atrial septal defects in individuals undergoing percutaneous repair by 64-detector row computed tomography.

Transcatheter atrial septal defect closure is becoming more commonplace as it has been demonstrated to be safe, efficacious and associated with low morbidity. Pre-procedural assessment of individuals has primarily relied upon transesophageal echocardiography. We present four individuals who underwent both transesophageal echocardiography as well as cardiac multidetector computed tomography. In all four cases, multidetector computed tomography added incremental information above the transesophageal echocardiogram. Multidetector computed tomography may play an essential role in individuals with atrial septal defects undergoing percutaneous transcatheter closure.
