The panels show subcostal four chamber echocardiographic cuts revealing malalignment between the atrial and muscular ventricular septal structures in a heart with straddling and overriding of the tricuspid valve. Note the tendinous cords attached to a papillary muscle (yellow asterisk) within the left ventricle. The left hand panel shows the diastolic, and the right panel the systolic location of the overriding leaflets.
