12-year-old male with a small muscular apical ventricular septal defect ventricular septal defect. Ecocardiography in (a) a long-axis four-chamber plane b) color Doppler image shows the presence of a small apical muscular ventricular septal defect (arrow in b).

The report was as follows: Situs solitus, normal atrio-ventricular and ventricular-arterial connections, no ASDs; small muscular apical VSD of 3 mm in diameter [Figure 1] and patchy appearance of the posterior wall of the LV. The cine SSFP sequences showed a hypertrabeculation of the mid-lateral and inferior wall and of the apical septum with a ratio between normal and hypertrabeculated myocardium of about two [Figure 2 and Video 1].
12-year-old male with a small muscular apical ventricular septal defect. Cine true-fast imaging with steady-state precession short-axis in the apical portions in (a and c) systole and (b and d) diastole show hypertrabeculation of the myocardium of the left ventricle (arrow).

The cine SSFP sequences showed a hypertrabeculation of the mid-lateral and inferior wall and of the apical septum with a ratio between normal and hypertrabeculated myocardium of about two [Figure 2 and Video 1]. During the first-pass perfusion, a jet of highly concentrated contrast material was clearly visible from the apical VSD throughout the RV [Figure 3 and Video 2].
12-year-old male with a small muscular apical ventricular septal defect (VSD). First Pass Perfusion long-axis four-chambers shows the passage of the contrast material through a) the right chambers (*), then b) through the left (+) chambers. (c, d), When the right chambers are empty and clear the image shows the passage of the contrast material (arrow) from left to right ventricle through the small apical muscular ventricular septal defect
