Locally derived system for cardiac operative risk evaluation.

Introduction: During the last two decades, many authors have found that European Systems for Cardiac Operative Risk Evaluation (additive and logistic models) overestimate the risk in cardiac surgery. The new European model has recently been introduced as an update to previous versions. The aim of the study was to investigate the significance of locally derived system for cardiac operative risk evaluation and to compare its predictive power with the existing European systems.

Clinical performance of the EuroSCORE II compared with the previous EuroSCORE iterations.

Background: The European System for Cardiac Operative Risk Evaluation (EuroSCORE) II has been recently introduced as an update to the previous versions. We sought to evaluate the predictive performance of the EuroSCORE II model against the original additive and logistic EuroSCORE models.

Patients And Methods: The study included 1,247 consecutive patients who underwent cardiac surgery procedures during a 14-month period starting from the beginning of 2012.

Vojvodinascore--local system for cardiac operative risk evaluation.

Introduction: The aim of the study was to investigate the prognostic value, sensitivity and specificity of both the logistic and additive European System for Cardiac Operative Risk Evaluation (as well as the European System for Cardiac Operative Risk Evaluation II and to assess the necessity for developing a local outcome prediction model in cardiac surgery.

Material And Methods: The research included 406 consecutive patients who had undergone cardiac surgical procedures at Institute of Cardiovascular Diseases of Vojvodina from January 2012 to July 2012. The authors compared the predicted mortality according to the additive and logistic European Systems for Cardiac Operative Risk Evaluation, the new European System for Cardiac Operative Risk Evaluation II and the observed mortality (30 days after surgery).

[Postoperative nonlethal complications following open heart surgery].

Background/aim: Postoperative nonlethal complications after open heart surgery are a serious clinical problem causing a considerable engagement of health workers, an augmented use of drugs, and prolonged operation incapac ity leading to prolonged hospital stay and increased expenses. The aim of the study was to establish whether there is any correlation between the level of expected operative risk and postoperative nonlethal complications.

Methods: A consecutive series of 853 patients subjected to the open heart surgery were investigated, 622 (73%) males and 231 (27%) females.

Patency of internal thoracic artery and vein grafts according to revascularized coronary artery properties.

Long-term results of surgical myocardial revascularization are determined by the quality of grafts and the progression of atherosclerosis in coronary arteries. The aim of the study was to evaluate the patency rate of internal thoracic artery and great saphenous vein grafts in relation to the hemodynamic properties of revascularized coronary artery. The patency of internal thoracic artery and great saphenous vein grafts was analyzed in relation to the degree of coronary stenosis estimated by angiography and the diameter of distal portion of coronary artery assessed intra-operatively.

[Prevention of sudden cardiac death by the implantable cardioverter defibrilator].

INTRODUCTION; Sudden cardiac death or, as it is also called, a modern man's killer occurs a few hours after the beginning of the disease. Sudden death is the one that happens within an hour from the onset of the subjective discomforts regardless of the existence of any previous disease. According to modern statistics, 450.

Myocardial revascularization without extracorporeal circulation in patients at high operative risk.

It is considered that over 25% of surgical patients with coronary artery disease are treated without extracorporeal circulation, i.e. off-pump coronary artery bypass.

[Ministernotomy: a preliminary experience in heart valve surgery].

Background/aim: The last decade of the 20th century brought up a significant development in the field of minimally invasive approaches to the valvular heart surgery. Potential benefits of this method are: good esthetic appearance, reduced pain, reduction of postoperative hemorrhage and incidence of surgical site infection, shorter postoperative intensive care units (ICU) period and overall in-hospital period. Partial upper median stemotomy currently presents as a state-of-the art method for minimally invasive surgery of cardiac valves.

[Evaluation of results in coronary surgery using EuroSCORE].

Introduction: The European System for Cardiac Operative Risk Evaluation (EuroSCORE) was developed in order to predict operative risk in cardiac surgery and to assess the quality of the cardio-surgical care. Introduction of the uniform terminology in result evaluation process leads to the significant improvement in measuring and evaluation of surgical treatment quality.

Objective: The aim of the study was to evaluate our results in isolated coronary surgery using the EuroSCORE.

[Hospital infections at the Department of Cardiovascular Surgery].

Introduction: Despite modern surgical techniques, preoperative preventive use of antibiotics and optimal treatment of operative site, patients who underwent surgical procedures are still at a risk of developing hospital infections. The aim of this paper was to estimate the frequency of hospital infections at the Department of Cardiovascular Surgery and their presence according to the anatomic localization as well as to identify the most frequent causes of hospital infections.

Material And Methods: During one-year period, all surgically treated patients were prospectively followed at the Department of Cardiovascular Surgery of the Institute of Cardiovascular Diseases, Vojvodina.

[Trends of risk factors in coronary surgery].

Introduction: In current era of widespread use of percutaneous coronary interventions (PCI), it is debatable whether coronary artery by-pass graft (CABG) patients are at higher risk.

Objective: The aim of the study was to evaluate trends in risk profile of isolated CABG patients.

Methods: By analysing the EuroSCORE and its risk factors, we reviewed a consecutive group of 4675 isolated CABG patients, operated on during the last 8 years (2001-2008) at our Clinic.

Surgical treatment of heart failure in patients with primary and ischemic dilated cardiomyopathy.

Objective: The aim of this study was to show hemodynamic and clinical improvement of heart failure after reductive annuloplasty of double (mitral and tricuspid) orifices (RADO) in the treatment of ischemic (IDCM) and primary (PDCM) dilated cardiomyopathy.

Materials And Methods: From November 1986 to July 15, 2002, 341 patients underwent operations for dilated cardiomyopathy. The IDCM group consisted of 231 patients (68%) with a mean ejection fraction (EF) of 23.

Reductive annuloplasty of double orifices in patients with primary dilated cardiomyopathy.

Background: Patients with primary dilated cardiomyopathy exhibit extensive remodeling of the left ventricle, mitral and tricuspid annular dilation and both mitral and tricuspid regurgitation. These factors significantly contribute to heart failure, and are predictors of early lethal outcome. The aim of this study is to show hemodynamic and clinical improvement after reductive annuloplasty of both mitral and tricuspid orifices in primary dilated cardiomyopathy.
