💠Pericardial shell ➡️dissociation between intrathoracic pressure (PCWP) and intracardiac (ICP) ∆s
💠Inspiration: PCWP outside the sac &⬇️; ICP inside the sac and ≠ ⬇️
💠⬇️driving gradient & LV doesn’t fill as well.

💠To dx V interdependence: turn on respirometer on machine (ask a sonographer!)
💠Other D/O also have V interdependence (tamponade)
💠Annulus reversus (lateral e’ < septal – opposite of usual). Lateral not septal
myocardium bound by pericardium
