JACC: Case Reports, vol.4, no.24, 2022 (Scopus)
© 2022In this clinical vignette, we describe a case of a patient with windsock-like posterior mitral annulus perforation at the site of annular calcification caused by infective endocarditis. Three-dimensional transesophageal images of the perforation resembling an “alien's mouth” are very striking for how 3-dimensional imaging can improve visualization of anatomy of the heart.
