Implication

3DE may support VSD sizing in surgical candidates; leaves open prospective validation before practice change.

Does 3-dimensional echocardiography accurately measure the dimensions of ventricular septal defects compared to anatomic and surgical measurements?

Population

9 explanted porcine hearts with 17 experimentally created VSDs, and 51 patients with VSDs (25 with comparative surgical measurements)

Intervention

Volume-rendered 3-dimensional echocardiography (3DE)

Comparator

Direct anatomic measurements (in vitro) and surgical measurements (in vivo)

Outcome

Correlation of major and minor axis diameters of VSDs between 3DE and anatomic/surgical measurementssurrogate

3-dimensional echocardiography provides accurate visualization and measurement of ventricular septal defects, correlating well with direct anatomic and surgical measurements.
