An 80-year-old woman with a history of mitral and aortic prosthesis replacement with biological prostheses due to endocarditis presented worsening dyspnea. A transthoracic echocardiogram demonstrated a paravalvular regurgitation between the left ventricle and left atrial appendage. Given her high-risk surgery (EuroSCORE-II: 38%), a percutaneous approach was performed for definitive closure. Transesophageal echocardiography (TEE) peri-procedure allowed the visualization of a partial dehiscence of the mitral prosthesis (Panel A, ). Through the 3D images, a tunneled defect with wall dissection measuring 12.5 […]
