🧵 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

"1/15" I posted my method to investigate LV diastolic function and was questioned about two unusual aspects: 1) relaxation o LV was analyzed on a 2D PLAX view (how come?); 2) LA size was analyzed by eyeballing (eyeball ????????). Even though I explained in an extensive article.
"2/15" I made this thread to be better understood. Some necessary tenets: normally, 70% of the total diastolic volume reaches LV by the initial 1/3 of diastole, during the rapid filling phase, and 30% by the remaining 2/3. This relation is inverted when relaxation is abnormal.
"3/15" During systole, mitral annulus is pulled in an apical direction. During diastole it recoils, just as an elastic rubber band, in response to its filling. Normally, 70% or close to 100% of its systolic pulling recoils during the initial 1/3 and just 30% or less at the end.
