He was asymptomatic from a cardiovascular perspective, but his activity level was less than four metabolic equivalents. Physical examination was notable for a 2/6 systolic murmur at the apex. ECG showed sinus rhythm. A transthoracic echocardiogram was performed (figure 1 and online supplementary video 1).DC1SP110.1136/heartjnl-2018-313413.supp1Supplementary file 1 heartjnl;104/22/1887/F1F1F1Figure 1Transthoracic echocardiography.
