Echocardiography guidance of atrial septal defect closure.

Transcatheter procedures offer less invasive approaches allowing rapid recovery and earlier hospital discharge. A number of international guidelines have defined the role of echocardiography spanning diagnosis, detailed anatomical assessment, device sizing and selection, peri-procedure guidance and post device surveillance. This review discusses the role of echocardiography in transcatheter atrial septal defect (ASD) closure. It describes a systematic approach to assessment including the crucial role of three dimensional echo and provides the reader with key information required during device sizing and procedure guidance.
