Figure 4.
Two-dimensional transthoracic echocardiographic views of case #4, (A); Biventricular apical SAX view, (B,C); Transesophageal gastric views, illustrating hypertrabeculated apical portions in addition to deep intertrabecular recesses. (D); Color Doppler echocardiography, showing evidence of direct blood flow from the ventricular cavity into deep intertrabecular recesses. (E–G); Two- and three-dimensional mid-transesophageal echocardiographic views, showing a large ostium primum type of atrial septal defect with left to right shunt. (H); Speckle tracking echocardiographic findings, compatible with myocardial performance impairment, mild in apical to severe in basal segments, and GLS = −10.9%. (I–L); Twelve-lead electrocardiography and a couple of tracings at different times, showing complete heart block and sustained runs of wide QRS tachycardia.
