Color Doppler detection of multiple ventricular septal defects.

摘要: Combined two-dimensional and Doppler echocardiography has a high sensitivity specificity for detection of isolated perimembranous ventricular septal defects. However, muscular or multiple defects may be difficult to diagnose with noninvasive methods, particularly in older children, necessitating angiography accurate diagnosis. Detection single color flow mapping was compared by standard imaging Doppler. Both techniques were four-chamber left angiography. Fifty-one patients (age 3 months 25 years, mean 5.6 years) studied. Eighteen had solitary defects, 18 15 intact septum served as control group. At least one defect detected two-dimensional/Doppler methods all proved no false positives. In the 72% that 38% (100% both). Color failed identify five (two weighing less than 4 kg three reduced pulmonary blood flow). large additional missed is useful higher The contribution appears small
