Transcatheter aortic valve implantation (TAVI) has been validated as a reliable therapy for aortic stenosis (AS), similar to surgical aortic valve replacement. Due to the methodological differences between the two therapeutic options, each has unique complications. We experienced a hitherto unreported complication of TAVI. An 81-year-old man underwent TAVI for severe AS. Acute mitral regurgitation (MR) occurred during valve deployment. Interference of the guidewire with the mitral subvalvular structure caused transient severe MR, leading to the development of pulmonary hemorrhaging. During TAVI, careful attention should be paid to the position of the guidewire, changes in hemodynamics and degree of MR.
