Pulsed wave TDI17 of the systolic tricuspid annular motion [13,18] (cm/s) at the lateral free wall (TVlat) and at the septal wall (TVsept) was obtained from the apical 4-chamber view using a pulsed wave doppler sampling gate of 2-4 mm and a sweep of 100-150 mm/s, as follows: one during the early phase of diastolic myocardial velocity (Em) and another during the late phase of diastolic myocardial velocity (Am) [19, 20]
(d) Apical 4-chamber transthoracic echocardiogram at 1 year follow-up showing no evidence of recurrent myxoma in the left atrium and persistent significant left ventricular dilatation.
Tissue Doppler Imaging (TDI) parameters were measured from 2-D images in apical 4-chamber and 2chamber views.

Mitral inflow measurements (early and late diastolic velocities and deceleration time) were obtained from pulsed-wave Doppler in the apical 4-chamber view.
The two-dimensional images were acquired and measured in the parasternal (standard long- and short-axis images) and apical 4-chamber views, according to the guidelines of the American Society of Echocardiography (ASE).[sup][5] Right ventricular (RV) linear dimensions were estimated from an RV-focused apical 4-chamber view.

The presence of the LV apical thrombus was not detected by a conventional parasternal sweep or apical 4-chamber view but detected only by an off-axis view as we searched intensively due to the ischemic stroke (Figure 2).
Mitral inow was assessed from the apical 4-chamber view with pulsed wave doppler by placing sample volume between the tips of the mitral leaets during diastole.
