Effects of Preoperative Aspirin Use on Mortality in Coronary Artery Bypass Grafting Patients

Background and Aim: Discontinuing aspirin use in patients before coronary artery bypass grafting (CABG) has focused on bleeding risks. The aim of this study was to determind the effect of aspirin use on overall mortality with this procedure.Materials and Methods: In a retrospective review was under taken of 2,252 consecutive isolated coronary artery bypass grafting (CABG) procedures performed between July 1995 and May 3003 in Tehran, Shriati hospital. Patients who had isolated CABG operations and received aspirin were analyzed and compared to nonusers undergoing similar bypass procedures during the same period. Aspirin use was defined by identification of ingestion within 7 days before the operation.Results: CABG patients using preoperative aspirin were less likely to experience in hospital hemorrhage compared to nonusers (P=0.0001). Significant difference was seen for transfusion of blood products, and need for reexploration for hemorrhage between patients who did and did not receive aspirin (P=0.0001).Mortality in multivariate (odds ratio [OR] =0.12, 95%confidence interval [0.05, 0.28] analysis was less to patients using aspirin compared to nonusers (p=0.0001).Conclusions : Preoperative aspirin use appears to be associated with a decreased risk of mortality in CABG patients with significant increase in hemorrhage, blood product requirements, or related morbidities

Mesenchymoma of the left atrium

Mr.M.H. 27 years old, is referred with symptoms and signs of inflow portion obstruction of the left heart. Laboratory test and echocardiography confirmed this diagnosis and revealed the presence of a tumor involving left atrium and mitral valve. The patients underwent operation and a tumor of left atrium with adhesion to the base of mitral valve posterior leaflet and another mass which existed on the mitral valve anterior leaflet were taken out. Histopathological examination of the tumor led to the diagnosis of mesenchymoma. Mesenchymoma is one of the rare connective tissue tumors and even more rarely is observed in the heart. Rare cases of cardiac mesenchymoma have been reported in literature since 1966 (A.D.) and this is the first case of mitral valve mesenchymoma to be introduced to literature

A case report of partial anomalous pulmonary venous connection and its surgical repair

This article aim is to introduce a case of PAPVC (partial anomalous pulmonary venous connection). The patient was a 25-year-old women who had dyspnea and palpitation. She expressed no special disease, no past medical history, and no drug usage, but her brother and her aunt had the above-mentioned history. In the physical examination, lungs were clear and the heart had S2 splitting, and there was a systolic murmur in the pulmonary area. Her liver could be palpitated two centimeters below the costal edge, but she didn't have any hepatomegaly. In cardiac catheterism, she had PAPVC, atrial septal defect (ASD), and mitral valve prolapse (MVP). The patient underwent operation had left pulmonary vein was separated from the superior vena cava and anastomosed to the left atrial auricle. By means of the pericardial patch, the left atrium became enlarged and ASD was closed. She was in a good condition after surgery and left the hospital without any complication with a good condition and recovery and had no problem any longer
