Assess septal motion and right ventricular hypertrophy |
Image and colour of right ventricular outflow tract, pulmonary artery and branches |
Measure maximum velocity at any areas of aliasing |
Assess pulmonary and tricuspid regurgitation from colour signals |
Measure right ventricular pressure from tricuspid regurgitation velocity |
Look for a residual ventricular septal defect |
Measure aortic root size and look for aortic regurgitation |
Remember in distal obstruction imaging poor and spectral velocity unreliable |
• right ventricular pressure may give better indication of obstruction |
