Four chamber view plus three-vessel and trachea view for a complete evaluation of the fetal heart during the second trimester
Objective: To test the efficacy of a recently introduced ultrasonic scanning plane (three vessel and trachea view -3VTV- plus color flow mapping -3VTVC) on a low-risk population for detection of congenital heart disease (CHD).
Patients and setting: Antenatal clinic dealing with local low-risk population. All antenatal patients having a second trimester scan in a 1 year period. All patients had a 3VT plus 3VTC views added to routine four chamber view. Postnatal examinations were performed according to standard hospital protocol.
Results: 2847 patients were examined. The plane was achievable in all 23 fetuses with CHD detected, three false negative (aortic coarctation) and two false positive. Sensitivity of the examination was 88.5%, as high as more sophisticated and difficult targeted cardiac scanning. The extra time necessary to perform the test was minimal.
Conclusion: 3VTV and 3VTCV were satisfactory used as imaging planes in a busy antenatal clinic in a low-risk population. They could be easily added to the four chamber view as routine screening for CHD and increase the detection rate to 90%.
