摘要

An 83-year-old male patient presented to our hospital with complaints of chest pain, shortness of breath, and leg swelling. His medical history included a biological mitral valve replacement (MVR) for mitral stenosis 9 years ago and percutaneous coronary intervention (PCI) to the circumflex (CX) and diagonal arteries 5 years ago. Echocardiography and coronary angiography (CAG) revealed moderate mitral valve stenosis, left atrial thrombus, and critical stenosis in the left main coronary artery (LMCA) and CX artery. Redo MVR, coronary artery bypass grafting (CABG), tricuspid valve repair, and thrombus excision were planned. However, CABG could not be performed due to extensive pericardial adhesions. After redo MVR, during LMCA stenting, the proximal portion of the stent protruded towards the aorta and hemodynamic instability developed. The protruded stent was surgically removed, and a drug-eluting stent (DES) was successfully implanted into the LMCA.
