Sumario:An 82-year-old female patient with severe mitral regurgitation was referred for evaluation of percutaneous mitral valve repair. Transoesophageal echocardiography revealed a left-atrial septal pouch (LASP) with an echogenic structure. Following the heart-team decision, interventional therapy was therefore discarded. During surgery, a thrombus in the LASP was found and carefully resected. Afterward, conventional valve replacement with a biological 31-mm SJM-EPIC prosthesis (Abbott Structural Heart Devices, Santa Clara, CA) was performed. In the fast-evolving field of interventional mitral valve therapy, a trans-septal approach is the common strategy. Therefore, careful evaluation of the interatrial septum—which may contain thrombi with transoesophageal echocardiography before intervention—is of crucial importance.
