In the following case report, we present two clinical cases of patients after valvular intervention and percutaneous occluder implantation into the left atrium. The first patient is a 68-year-old male admitted to the Department of Cardiology because of Non- ST-Elevation Myocardial Infarction (NSTEMI). He had a medical history of paroxysmal atrial fibrillation and implantation of a biological mitral prosthesis due to severe secondary mitral regurgitation. Due to contraindications to the chronic use of anticoagulants, the patient underwent percutaneous closure of the left atrium appendage. The second patient is an 80-year-old man with a history of permanent atrial fibrillation. Eight years ago, the patient underwent percutaneous Atrial Septal Defect type II (ASD II) closure with and the Amplatzer occluder. A year later, the patient underwent Coronary Artery Bypass Graft (CABG) and biological mitral valve implantation due to multivessel coronary disease accompanied by severe mitral regurgitation. In both patients, Transthoracic Echocardiogram (TTE) showed massive thrombosis in the left atrium.
