Question 17 of 17:
Clinical and hemodynamic recovery occurs eventually in patients with right ventricular dysfunction.
You clicked 'False'
Incorrect!
Clinical and hemodynamic recovery eventually occur even in patients with right ventricular dysfunction (1-4) This return to normal may be due to improvement of concomitant LV dysfunction, resulting in a reduction in right ventricular afterload or to a gradual stretching of the pericardium with amelioration of its restraining effect (2).
