🧵 1/9 Thread on constrictive pericarditis. Syncing pathophysio, imaging & hemodynamics to macroscopic findings. @AvrahamCooperMD #CardioTwitter #MedTwitter #echofirst #HeartFailure @YoungDgk @Kardiophil @fuzzymittens @CardioNerds @kardiologie_org @DjawidHashemi @KardiologieHH 2/9 Being a fibroelastic sac the pericardium covers & protects the #heart

In constrictive pericarditis:
1️⃣healing of acute pericarditis
2️⃣granulation tissue
3️⃣obliteration of pericardial cavity
4️⃣loss of pericardial elasticity
5️⃣restriction in ventricular filling
