The patient's electrocardiogram. The black arrow indicated the first-degree
atrioventricular block. The red arrows indicate the poor R-wave
progression.

A 12-lead electrocardiogram revealed sinus rhythm with a first-degree atrioventricular block and poor R-wave progression (see Figure 1).
Two-dimensional transthoracic echocardiography series. (a) Parasternal
long-axis view indicates the width of the central regurgitant jet, deemed
trivial-mild. (b) A cross-sectional view of the aortic valve reveals the
quadricuspid architecture enclosed by the red circumference. This is
consistent with Hurwitz-Roberts class A and Nakamura type I morphology. (c)
A cross-sectional view of the aortic valve reveals the central to mild
trivial aortic regurgitant jet.

Two-dimensional transthoracic echocardiography (2D-TTE) demonstrated a QAV with trivial to mild AR (see Figure 2a-c).

A cardiac CT angiogram also revealed nonobstructive coronary artery disease with a calcium score of 0 and QAV (see Figure 3).
