Left ventricular (LV) pseudoaneurysm is a rare complication that occurs shortly after myocardial infarction or previous cardiac surgery. We present here a case of an elderly patient with an LV pseudoaneurysm that developed over a long period of time after Dor operation. An 83-year-old man with rapid LV enlargement 18 years after Dor operation presented with dyspnea. We diagnosed his mass as an LV pseudoaneurysm using multiple non-invasive imaging modalities. The suture between the patch and the LV myocardium became fragile and detached over time. However, due to adhesion in the thorax and slow blood flow, the enlargement stopped. Surgery was considered, but due to his age and renal dysfunction, he did not undergo surgery. Conservative treatment with antihypertensive and heart failure therapy was continued. Clinical manifestations of LV pseudoaneurysm vary from asymptomatic to signs of heart failure and even sudden death. Surgery is recommended for LV pseudoaneurysm because of the high risk of rupture, but conservative treatment may be an option that has been developed long after surgery in the era of an increasing number of elderly OMI or post-cardiac surgery patients. Proper diagnosis using multiple imaging modalities may lead to the avoidance of this devastating complication.
