Pulsed Wave Doppler: Parasternal Short Axis View Pulmonary Artery

NC012e-2.jpg

NC012a.jpg

Sample Volume: In the Right Ventricular Inflow Tract (RVIT)
Normal Flow: Primarily diastolic
Abnormal Finding: Increased diastolic flow velocity and spectral broadening due to tricuspid  stenosis.


NC012b.jpg

Sample Volume: In the Right Atrium (RA)
Normal Flow: Diastolic
Abnormal Finding: High velocity retrograde systolic flow and spectral broadening due to tricuspid  regurgitation.


NC012c.jpg

Sample Volume:    In the Right Ventricular Outflow Tract (RVOT)
Normal Flow:    Systolic
Abnormal Findings:
  1. Increased systolic flow velocity and spectral broadening due to a subpulmonic stenosis, or to a ventricular septal defect.
  2. High velocity retrograde diastolic flow and spectral broadening due to pulmonic insufficiency.


NC012d.jpg

Sample Volume:    In the Pulmonary Artery (PA)
Normal Flow:    Systolic
Abnormal Findings:
  1. High systolic flow velocity and spectral broadening due to a pulmonic or subpulmonic stenosis.
  2. Continuous (systollic and diastolic) nonlaminar flow due to a patent ductus arteriosus.
