FIGURE 1 (A) Color doppler flow imaging (CDFI) shows the ventricular septal defect of 0.5 cm (Arrow); shunt from left to right. (B) Tricuspid anterior leaflet atrial surface slightly hyperechoic with a mass about 0.9 x 0.6 cm (Arrow), oscillating with anterior leaflet. (C) Arrow shows interrupted echo continuity of the anterior lobe of the tricuspid valve (about 0.2 cm). (D) The CDFI shows tricuspid regurgitation, in which a beam of regurgitation came from the interrupted echo of the anterior lobe of the tricuspid valve (Arrow). LV: left ventricle; RV: right ventricle; RA: right atrium.
