BACKGROUND Patency of the revascularization conduit is an essential predictor of long-standing survival after coronary artery bypass grafting. OBJECTIVES We have conducted this study to compare the mid-term patency rates of radial artery (RA), left internal thoracic artery (LITA) and also saphenous vein (SV) grafts in asymptomatic patients following(More)
BACKGROUND Pleurotomy during coronary artery bypass grafting (CABG) may cause post-operative events, mostly pulmonary complications. In this study, we evaluated the influence of pleurotomy during CABG on the clinical outcome following left internal mammary artery (LIMA) harvesting. METHODS Between March and August 2009, 102 patients who underwent cardiac(More)
BACKGROUND Despite the advances in pain control following surgery, data on the location and distribution of pain following coronary artery bypass grafting (CABG) are lacking. OBJECTIVES This study was intended to investigate the location, distribution, and intensity of pain in patients undergoing CABG during their postoperative hospital stay from the(More)
INTRODUCTION Excessive bleeding presents a risk for the patient in cardiovascular surgery. Local haemostatic agents are of great value to reduce bleeding and related complications. TachoSil (Nycomed, Linz, Austria) is a sterile, haemostatic agent that consists of an equine collagen patchcoated with human fibrinogen and thrombin. This study evaluated the(More)
BACKGROUND Pregnant patients with mechanical heart valves require anticoagulation. The risk of bleeding and embryopathy associated with oral anticoagulants must be weighed against the risk of valve thrombosis. METHODS In this prospective study, undertaken between 1999 and 2009, 53 pregnancies (47 women with mechanical mitral valves; 29.8 ± 4.8 years old)(More)
INTRODUCTION Standards have a significant role in showing the minimum level of optimal optimum and the expected performance. Since the perfusion technology staffs play an the leading role in providing the quality services to the patients undergoing open heart surgery with cardiopulmonary bypass machine, this study aimed to assess the standards on how(More)
Dear Editor, We read with great interest the recent article by Nouei et al. [1]. They have reported a study for developing a Genetic Fuzzy System for risk assessment of mortality after cardiac surgery. Using demographic, comorbidity, cardiac status, and para-clinical variables and applying ad hoc data-driven and hybrid optimization methods to generate the(More)
Pseudoaneurysms of the ascending aorta, which are rare and life-threatening complications in cardiovascular surgeries, can be caused by the Bentall procedure. We describe a 44-year-old woman, who had a medical history of acute aortic dissection (Type A) and the Bentall procedure and was admitted because of exertional dyspnea, edema of the lower extremities,(More)
INTRODUCTION Excessive fibrinolysis contributes to post-cardiopulmonary bypass bleeding. Tranexamic Acid (TXA) and Caproamin Fides are synthetic lysine analogues that inhibit plasminogen-fibrin binding. The present study aimed to compare TXA and Caproamin Fides versus placebo in patients undergoing elective coronary artery revascularization. METHODS We(More)
BACKGROUND The objective of this study was to assess the results of the pulmonary artery (PA) banding in patients with congenital heart defects (CHD) and pulmonary hypertension (PH) in the current era. METHODS We analyzed data from 305 patients who underwent PA banding between April 2005 and April 2010 at our centre. All patients were approached through a(More)
