Volume atrial mínimo

Baseline clinical data were obtained from a comprehensive review of each patient’s medical record. The definitions for all clinical conditions have been previously described. 12 LA volume was measured offline using the biplane area–length method 15 and indexed to body surface area. Minimum and maximum LA volumes were obtained at mitral valve closure and just before mitral valve opening, respectively. Left ventricular ejection fraction and LV mass were determined by standard 2D-echocardiography methods. 15 LV diastolic function was classified by Doppler assessment of mitral inflow, pulmonary venous flow, and tissue Doppler imaging of septal mitral annular motion. The grading of diastolic dysfunction is as follows: Grade 1: impaired relaxation; Grade 2: pseudo normal pattern; and Grade 3/4: reversible/irreversible restrictive pattern. 16

Conceito interessante de medir o AE quando ele está vazio.

Quando a Mitral está aberta, AE e VE funcionam como uma cavidade única.

.

Trabalho esquecido na internet mas que levanta uma questão relevante.

.

Deveríamos medir o volume do AE com a Mitral aberta?
