Introduction:This study evaluated the frequency of domination of the coronary arteries types in patients treated by surgical myocardial revascularization. The aim of the study was to determine whether the left coronary circulation dominance is a prognostic factor for poorer outcome in patients undergoing coronary artery bypass surgery.Material and methods:A total sample consisted of 100 patients with coronary artery disease that were treated with coronary artery bypass grafting at the Clinic for Cardiac Surgery, Clinical Center of the University of Sarajevo. To all patients on the basis of preoperative coronary angiography was determined the dominance of the coronary arteries. Patients included in the study were divided into two groups, with the left and right with coronary dominance.Results:Left coronary dominance in a sample of patients was present in 21/100 (21%), right in 69/100 (69%) and balanced in 10/100 (10%) cases. Female gender was significantly more frequent in patients with left coronary dominance and proved to be a stronger predictor of poorer outcome, especially in combination with left main stenosis of the left coronary artery and left coronary dominance. Inability of revascularization of the r. interventricularis posterior (RIVP) was statistically significantly higher in case of left dominance 9/21 (42.9%), compared to the right 16/79 (20.3%), p=0.033. Lethal outcome was more common in case of left dominance in relation to the right (9.4% vs 0.9%). The incidence of surgical complications, respiratory, neurological and renal complications was not significantly different between groups, while the length of hospital stay was significantly higher in the group of patients with left dominance, p = 0.003.Conclusion:Left coronary dominance is an important risk factor for patients undergoing surgical myocardial revascularization.
Background: Cardiac myxoma is the most common benign tumor of the heart. It presents with a variety of clinical signs and symptomatology making diagnosis frequently quite a challenge. Objective: The aim of this article is to present a case report of giant right atrial myxoma with symptoms of right heart failure in adult patient. Case report: We present a case of large right atrial myxoma which is an uncommon location for this type of heart neoplasms, discovered incidentally in a female patient 77-year-old who came to our polyclinic for cardiological exam with hypertension last 11 years and obesity. Results and Discussion: Various clinical signs and symptoms produced by cardiac myxomas have been reported in the literature. Depending on location and morphology, cardiac tumors can produce four types of clinical manifestations: systemic-constitutional, embolic, cardiac, and secondary metastatic manifestation. Echocardiography as non-invasive imaging method and Transesophageal echocardiography has superior role for precise evaluation of cardiac tumors. Transesophageal echocardiography has superior role for accurate diagnostic evaluation of cardiac mass. Surgical excision of cardiac myxoma carries a low-operative risk and gives excellent short- and long-term results. Conclusion: Myxoma is the most prevalent primary heart tumor. It is rare to find a myxoma in the right atrium, occurring only in 15-20% of myxoma cases. Clinical manifestations of myxomas consist in a triad: constitutional symptoms, embolization and intracardiac obstruction. Transesophageal echocardiography has superior role for precise evaluation of cardiac tumors. Currently, there is no effective medical treatment, and surgical excision of the tumor is necessary.
Introduction:Modern pediatric cardiology mainly deals with congenital heart defects (CHD), as the most common congenital anomalies. In most cases CHD requires surgical or interventional treatment.Goal:The goal of the research was to evaluate CHD treatment at Pediatric Clinic, University Clinical Center (UCC) Sarajevo, Bosnia and Herzegovina (B&H). UCC Sarajevo is the only institution in B&H where cardiac treatment of CHD in pediatric population is performed. Pediatric cardiosurgery has started to develop in Bosnia and Herzegovina in April 1997.Patients and methods:Study included 745 patients (period from April 1997 to January 2017).Results:Cardiac treatment was performed on 745 patients with CHD, 541 (72.6%) of them were acyanotic patients and 204 (27.4%) were cyanotic patients. Reoperation was performed in 49 (6.5%) of patients. Out of total number of patients, 59 (7.9%) died. In 660 children (88.5%) a complete correction and in 85 (11.5%) a palliative operation/correction was performed. Defects with left to right shunt were present in 397 (53.2%) patients, complex heart defects with Tetralogy of Fallot in 173 (23.2%), obstructive heart defects in 106 (14.2%), obstructive heart defects with shunt in 53 (7.1%), and others in 16 (2.1%) of patients. During surgery, extracorporeal circulation was regulated in 554 (74.3%) patients. Peri and early postoperative complications occurred in 180 (24.1%) of patients. During this period 24 pacemakers were implanted and 24 radiofrequency ablations were performed.Conclusion:Results of CHD cardiac treatment in childhood, which took place simultaneously, followed by the contractual joint programs and individual work of the Bosnian and Herzegovinian team has reached the highest level in the last two years, not only by the number, type and complexity of corrected CHD, but also by the age and body weight of the patients who underwent surgery, and development of invasive procedures, arrhytmology, pacemaker placement, intensive peri and postoperative treatment. That led pediatric cardiac surgery of UCC Sarajevo, to a position of leading center in the region.
Introduction: Despite recent advances in anesthesia, cardiopulmonary bypass and surgical techniques, children undergoing congenital heart surgery require postoperativemechanical ventilation� Early extubation was definedas ventilation shorter than 12 hours� Aim of this study is to identify factors associated with successful early extubation after pediatric cardiac surgery�
