Question 2

what is constrictive pericarditis

Answer 2

granulation tissue formation in pericardium which results in a loss of pericardial elasticity

Question 3

etiology for Constrictive Pericarditis

Answer 3

1. idiopathic
2. surgery
3. viral/bacteria
4. radiation

Question 4

echo physiologic features you will see for Constrictive Pericarditis

Answer 4

1. dissociation of intrathoracic and intracardiac pressures
   -. respiratory variation in LV and RV filling/emptying
2. exaggerated lv - rv interdependence
   -. septal bounce
3. tethering the posterior wall and MV annulus
   -reduced of MV lateral DTI velocity and abnormal strain
