Added value of three dimensional transesophageal echocardiography in
percutaneous closure of atrial septal defect.
Abstract
Unrepaired secundum ASD (atrial septal defect) is the commonest
congenital heart disease encountered in adulthood. In this study we try
to correlate the three-dimensional size of a secundum ASD to the device
size. We did a retrospective analysis to 36 patients who underwent
successful transcatheter closure of atrial septal defect guided by
balloon sizing and correlated this to the device size. The device size
was correlated significantly with all the maximal ASD diameter by
2D-TTE, 2D-TEE and 3D-TEE. However, the most significant correlation was
between three-dimensional maximal diameter and device. 3D TEE is a
promising and reliable tool that can be used to determine the size,
number and shape of ASD and to accurately select the suitable device
size during percutaneous closure.
