Parasternal Short Axis

  • 304 Accesses

Abstract

The parasternal short axis (PSA) is the second window in a transthoracic echocardiogram (TTE). It is one of the most overlooked images in the TTE. The PSA allows for qualitative assessment of left ventricular (LV) function, and LV hypertrophy. It is also important in assessing right ventricular (RV) function, and assessing for RV pressure volume overload evidenced by a D-shaped LV, or flat interventricular septum. The measurement of tricuspid regurgitant velocity in the aortic valve window is a predictor for pulmonary hypertension.
