Doppler echocardiography is a powerful diagnostic modality for evaluating the anatomical and pathophysiological consequences of ventricular septal defects in adults.
Ventricular septal defects account for 10% to 15% of all congenital heart defects observed in adults. The type of defects observed tend to fall at the extreme ends of the spectrum: small restrictive defects with minimal shunts, and large nonrestrictive defects associated with severe occlusive pulmonary vascular disease. Doppler echocardiography has evolved into a powerful diagnostic modality that comprehensively evaluates the anatomical and pathophysiological consequences of a ventricular septal defect. The spectrum of findings caused by ventricular septal defects is the subject of this review.
Peter S. Rahko (1993) studied this question.
