Values are mean ± SD or n (%).

AR + MVP = moderate or worse aortic regurgitation plus mitral valve prolapse; BAV = bicuspid aortic valve; BSA = body surface area; COPD = chronic obstructive pulmonary disease; IVSTd = interventricular end-diastolic septum thickness; LVEDd = left ventricular end-diastolic diameter; LVSV = left ventricular stroke volume; RL = right-left coronary; RN = right-noncoronary; STJ = sinotubular junction.

  • RL versus RN (unpaired Student t or chi-square test). Italicized p values are statistically significant.
