Dynamic aortic pouch: a rare etiology of aortic regurgitation.
The causes of aortic regurgitation (AR) include rheumatic heart disease, infective endocarditis, and various congenital and degenerative defects. We report an unusual case of AR in a 72-year-old man due to an aortic root pouch. The diagnosis AR was made by cardiac echocardiography, and the cause was revealed by cardiac catheterization and 64-slice cardiac computed tomography. During aortic valve replacement, a saccular pouch between the noncoronary cusp and the right coronary cusp of the aortic valve was noted.
