Answers are grounded in this paper and cite their sources.
Live/real-time 3DTTE provides accurate pre-operative characterization of ventricular septal defects that correlates well with intraoperative 3DTEE and surgical findings.
In this report, we present 12 patients (range 14-76 years, mean 40 +/- 22.7 years) who underwent surgical repair of a ventricular septal defect (VSD). Location, size, and surrounding anatomy of the VSD were assessed prior to intervention in all patients with live/real time three-dimensional transthoracic echocardiography (3DTTE). In 9 patients, measurements of maximum dimension, circumference, and area by 3DTTE correlated well with the same measurements from intraoperative three-dimensional transesophageal echocardiographic (3DTEE) reconstruction. 3DTTE measurement of maximum dimension of VSDs also agreed well with maximum dimension by surgery in 10 patients. Live/real time 3DTTE accurately defined VSD location, size, and surrounding anatomy in all patients studied by us. VSD characterization by live 3DTTE agreed well with surgery descriptions and 3DTEE measurements.

Mehmood et al. (2006) conducted a case report in Ventricular septal defect (n=12). Live/real time three-dimensional transthoracic echocardiography (3DTTE) vs. Intraoperative three-dimensional transesophageal echocardiography (3DTEE) and surgery was evaluated on Agreement of VSD characterization (location, size, anatomy) with surgery and 3DTEE.
