Aneurysmal dilatation of coronary arteries is characterized by abnormal dilatation of a localized or diffuse segment of the coronary arterial tree. Left main coronary artery aneurysms are rare coronary anatomic abnormalities. They rarely involve the left main coronary artery. Different strategies have been adopted, where the coronary artery aneurysms have been left as such, resected partially, isolated, reconstructed, ligated with a simultaneous bypass with internal mammary artery, or treated with vein grafts. We report a case of a successful ligation of aneurysm of the left main coronary artery and three simultaneous coronary artery bypass procedures (Fig. 1, Ref. 15).

Pericardial mesothelioma is a rare and highly aggressive and lethal cardiac tumour. A 25-year-old male patient who was complaining of fever, night sweats, shortness of breath and palpitations after an upper respiratory system infection was admitted in May 2008. He had a history of 12 years exposure to asbestos. When the patient was referred to our hospital in June 2008, his complaints of palpitations and shortness of breath were continuing. He had oedema of legs and a venous swelling on his neck. The echocardiography showed pericardial effusion and pericardial thickening which were also found on the CT. Through median sternotomy a pericardectomy and tumor resection were performed. Histological and immunohistochemical fi ndings lead to the diagnosis of malignant pericardial mesothelioma. In conclusion, there is still not a radical therapy for primary pericardial mesothelioma. Surgery is done to prevent cardiac tamponade and relieves constriction (Fig. 1, Ref. 12).
