Popis: Introduction Left ventricular pseudoaneurysm is a rare and often fatal complication of myocardial infarction. It has an incidence of 0,2-0,4% of all the STEMI and a very high mortality, particularly in the first month. Symptoms can vary from shortness of breath on exertion, orthopnea, chest pain, fatigue. At least 10% of patients do not present any symptoms and the pseudoaneurysm is diagnosed incidentally during a follow-up appointment. Signs include persistent ST elevation on EKG and its diagnosis can easily be made with a transthoracic echocardiogram and more in depth with a CT scan and a cardiac MRI. Its treatment is surgical, but the choice is up to the anesthesiologist and cardiothoracic surgeon, depending on patient's comorbidity and surgery risk. Surgical treatment has a high rate of death, reaching even the 37%. Background We present the case of a 74 years old patient with an history of chronic hypertension and cerebral vasculopathy, who sustained a STEMI in 2017. Urgent coronarography study was performed, but unfortunately the angioplasty treatment was unsuccessful and the left anterior descending artery could not be recanalized. Therefore, the patient was transferred to the cardiothoracic department in order to undergo bypass surgery: surgery was performed five days after, using left internal mammary artery to the left anterior descending artery and great saphenous vein to the first diagonal. Surgery went well with no complications; the post-operative period passed by without any complications and, after 15 days, patient was discharged with no complains. Two months later, he was admitted to intensive care unit of a hospital of our town, because of dyspnea (NYHA 3), peripheral edema, moderate-severe mitral insufficiency, moderate pleural and pericardial effusion. He underwent a CT-scan that showed “9×6,4 cm cavity with blood that seemed to have a connection with the postero-lateral wall of the left ventricle”. He also underwent a cardiac MRI that displayed a pseudoaneurysm with an endoluminal thrombus. After an accurate evaluation of the case, the Heart Team decided to do not perform surgery because of the high risk of the patient. Thence, we have been followed him with close echocardiographic exams for more than four years. Methods From March 2018 to September 2022, we have been followed the patient with complete echocardiographic follow-ups, done every three-six month. Results and conclusions Patient with left ventricle pseudoaneurysm due to an extensive myocardial infarction has been followed in our echo lab for more than 4 years. He has been stable during these years, NYHA II, in a good clinical and hemodynamical state.
