Figure 7: Critical pulmonary stenosis in at 32 weeks of gestation: (a) noncontractile right ventricle (left ventricular systolic contraction), nonrestrictive patent foramen ovale (PFO) (yellow arrow); (b) hyperechoic papillary muscle of TV; (c) TR; (d) modified parasternal short axis view: color Doppler: turbulent jet across the PV; (e) High velocity signal across the PV: 288 cm/s (gradient 33 mmHg). TV: Tricuspid valve, TR: Tricuspid regurgitation, PV: Pulmonary valve, RV: Right ventricle, RA: Right atrium, LA: Left atrium, LV: Left ventricle
