Biatrial contractility recovery after maze
Time Frame: 24 months
|
All patients were evaluated with 2-dimensional transthoracic echocardiography at 3,6,12,24 months in order to specifically monitor the evolution of cardiac chambers dimensions and systolic performance and to record left and right atrial contractility presence. Transmitral flow velocity was measured with pulsed Doppler echocardiography, with a sample volume positioned at the level of the mitral tip in the apical four-chamber view and was recorded on a strip chart at a paper speed of 100 mm/s. Peak velocity and the time-velocity integral of the early filling wave (E wave) and of the late filling wave (A wave) were determined. A/E ratio, representing atrial contribution to ventricular diastolic filling, was obtained. Each measurement was obtained as an average of 6 to 8 consecutive beats. |
