He was asymptomatic with no significant medical history. Physical examination revealed dual heart sounds with a grade II\/VI systolic murmur heard in the left sternal border. An ECG\u00a0was in normal sinus rhythm. TTE was performed (figure 1A\u2013C, online supplementary videos 1\u20134) followed by cardiac CT angiography (CTA) (figure 1D,E).<\/jats:p>\n                  <jats:fig id=\"F1\" position=\"float\" orientation=\"portrait\">\n                     <jats:label>Figure 1<\/jats:label>\n                     <jats:caption>\n                        <jats:p>(A) Transthoracic echocardiography, parasternal left ventricular long axis view.
