In severe TR, flow reversal during ventricular systole is usually when pulsed wave doppler is applied in _______________.

Normal pulmonary venous flow pattern, except.

• retrograde flow occurs in systole

the ____________ can be visualized from the suprasternal notch as a vertical structure just to the right of the aortic arch.

Normal variant found in RV

Patients with right ventricular ________ maintain septal flattening throughout the cardiac cycle, both systole and diastole.
