BACKGROUND The Adult Cardiac Surgery Databank (ACSD) of Tehran Heart Center was established in 2002 with a view to providing clinical prediction rules for outcomes of cardiac procedures, developing risk score systems, and devising clinical guidelines. This is a general analysis of the collected data. METHODS All the patients referred to Tehran Heart Center for any kind of heart surgery betwee...

In this paper, coronary arterial bypass grafting hemodynamics and anastomosis designs are reviewed. The paper specifically addresses the biomechanical factors for enhancement of the patency of coronary artery bypass grafts (CABGs). Stenosis of distal anastomosis, caused by thrombosis and intimal hyperplasia (IH), is the major cause of failure of CABGs. Strong correlations have been established ...

Background: Coronary artery revascularisation procedures (CARPs) include coronary artery bypass graft procedures (CABGs) and the less invasive percutaneous coronary interventions (PCIs) and they are common surgical interventions for coronary heart disease (CHD). The effectiveness of PCIs increased when stents were introduced and there was also a shift towards doing more PCIs and less CABGs, esp...

OBJECTIVE Traditionally, evaluation of outcome post cardiac surgery has focused on objective measures of cardiovascular status. The emphasis has shifted to examining an individual's quality of life (QoL). However a gap in Australian prospective research assessing QoL from a pre-operative period to the early stage of six weeks post-operatively exists. The aim of this study was to investigate rec...

results the mean age of patients was 60 ± 9.9 years. statistically significant relationship between the occurrence of af with mitral valve annulus, la volume index (lavi) , right ventricle function, and type of surgery (off pump or on pump) were detected in our study (p < 0.05) . there was no statistically significant relationship between the occurrence of af and time interval of p wave to a wa...

BACKGROUND Many studies have demonstrated that health related quality of life (HRQoL) improves, on average, after coronary artery bypass graft surgery (CABGS). However, this average improvement may not be realized for all patients, and it is possible that there are two or more distinctive groups with different, possibly non-linear, trajectories of change over time. Furthermore, little is known ...

OBJECTIVE To determine the frequency of cognitive impairment and its predictors in patients, who underwent first time coronary artery bypass graft surgery (CABGS). STUDY DESIGN An observational study. PLACE AND DURATION OF STUDY The National Institute of Cardiovascular Diseases (NICVD), Karachi, from December 2008 to December 2009. METHODOLOGY Study included patients > 18 years, who under...

BACKGROUND Venous coronary artery bypass grafts (CABGs) are prone to accelerated atherosclerosis. In atherosclerotic diseases, serum C-reactive protein (CRP) levels have become an important diagnostic and prognostic marker. The origin of CRP in this setting remains to be elucidated. METHODS AND RESULTS Monoclonal anti-CRP identified CRP expression in medial and intimal alpha-actin-positive sm...

Coronary artery bypass graft (CABG) surgery is associated with an improvement of survival and quality of life in patients with multivessel coronary disease and left main stenosis. However CABGs, similarly to the native coronary vessels, may in time, develop stenosis or occlusion. Invasive coronary angiography is considered the gold standard in the evaluation of CABG, but the technique is associ...
