Diastology Flashcards
Limitation of E/eā
Mitral stenosis
Prosthetic
MAC
Use ivrt when above
Annular velocities
Lat abn < 10 cm/sec
Sept abnl < 8 cm/sec
Normal pericardial fluid:
Thickness of pericardium:
50cc
Visceral single cell
Parietal <2cm
Right chamber collapse
RV early diastole
RA easily systole
MV/TV respiratory variation causes:
COPD, arrhythmia, deep breathing, PE, obesity
Pulmonary valve and elevated RV pressure:
May cause premature opening of pulmonic valve
IVRT
Aortic closure to MV opening
Components of diastolic function:
Preload of LA
Active relax of LV
Doppler component of diastolic function:
Mitral inflow
IVRT
Pul vein waves
Type 1 diastolic dysfunction
Low LV relaxation prolonges ivrt, decreases e, increases a
ivrt decreases with elevated LA pressure, increases E, decreases a
LA pressures from diastolic function
E<a>< 15 mmhg
Pseudonormal 15-20
Restrictive > 25 mmhg</a>
Pulmonic vein
Sys and Dias waves
Inverted a
Pul a < MV a increase pul a increased lapressure-
E velocity increased or decreased
Increased by increased la pressure
Decreased by less relax
Preload independent parameters of diastolic function:
Flow propagation vel E/fpv
Tissue Doppler velocity
IVCT
IVRT
Ivct: mvc till av opens
Ivrt: av closes till mv opens
